Subject: [PATCH 107/247] clk: at91: sama7g5: remove mck0 from parent list of
other clocks
MCK0 is changed at runtime by DVFS. Due to this, since not all IPs
are glitch free aware at MCK0 changes, remove MCK0 from parent list
of other clocks (e.g. generic clock, programmable/system clock, MCKX).

Subject: [PATCH 108/247] clk: at91: sama7g5: decrease lower limit for MCK0
rate
On SAMA7G5 CPU clock is changed at run-time by DVFS. Since MCK0 and
CPU clock shares the same parent clock (CPUPLL clock) the MCK0 is
also changed by DVFS to avoid over/under clocking of MCK0 consumers.
The lower limit is changed to be able to set MCK0 accordingly by
DVFS.

Since CPU PLL feeds both CPU clock and MCK0, MCK0 cannot go higher
than 200MHz and MCK0 maximum prescaller is 5 limit the CPU PLL at
1GHz to avoid MCK0 overclocking while CPU PLL is changed by DVFS.

Subject: [PATCH 111/247] clk: at91: sama7g5: register cpu clock
Register CPU clock as being the master clock prescaler. This would
be used by DVFS. The block schema of SAMA7G5's PMC contains also a divider
between master clock prescaler and CPU (PMC_CPU_RATIO.RATIO) but the
frequencies supported by SAMA7G5 could be directly received from
CPUPLL + master clock prescaler and the extra divider would do no work in
case it would be enabled.

Subject: [PATCH 112/247] clk: at91: Fix the declaration of the clocks
These are all "early clocks" that require initialization just at
of_clk_init() time. Use CLK_OF_DECLARE() to declare them.
This also fixes a problem that was spotted when fw_devlink was
set to 'on' by default: the boards failed to boot. The reason is
that CLK_OF_DECLARE_DRIVER() clears the OF_POPULATED and causes
the consumers of the clock to be postponed by fw_devlink until
the second initialization routine of the clock has been completed.
One of the consumers of the clock is the timer, which is used as a
clocksource, and needs the clock initialized early. Postponing the
timers caused the fail at boot.

Subject: [PATCH 116/247] net: macb: add capability to not set the clock rate
SAMA7G5's ethernet IPs TX clock could be provided by its generic clock or
by the external clock provided by the PHY. The internal IP logic divides
properly this clock depending on the link speed. The patch adds a new
capability so that macb_set_tx_clock() to not be called for IPs having
this capability (the clock rate, in case of generic clock, is set at the
boot time via device tree and the driver only enables it).

Subject: [PATCH 122/247] ASoC: atmel-i2s: do not warn if muxclk is missing
Besides the fact that muxclk is optional, muxclk can be set using
assigned-clocks, removing the need to set it in driver. The warning is
thus unneeded, so we can transform it in a debug print, eventually to just
reflect that muxclk was not set by the driver.

Subject: [PATCH 130/247] regulator: mcp16502: lpm pin can be optional on some
platforms
On some platform (e.g. SAMA7G5) LPM pin should be optional as it can
be controlled explicitly (via shutdown controller registers) in the
platform specific power saving code to decrease the power consumption
while suspended as this SoC pin may be connected to other devices that
could take power saving actions based on its value.

Subject: [PATCH 131/247] pinctrl: at91-pio4: add support for fewer lines on
last PIO bank
Some products, like sama7g5, do not have a full last bank of PIO lines.
In this case for example, sama7g5 only has 8 lines for the PE bank.
PA0-31, PB0-31, PC0-31, PD0-31, PE0-7, in total 136 lines.
To cope with this situation, added a data attribute that is product dependent,
to specify the number of lines of the last bank.
In case this number is different from the macro ATMEL_PIO_NPINS_PER_BANK,
adjust the total number of lines accordingly.
This will avoid advertising 160 lines instead of the actual 136, as this
product supports, and to avoid reading/writing to invalid register addresses.

Subject: [PATCH 132/247] dmaengine: at_xdmac: adapt perid for mem2mem
operations
The PERID in the CC register for mem2mem operations must match an unused
PERID.
The PERID field is 7 bits, but the selected value is 0x3f.
On later products we can have more reserved PERIDs for actual peripherals,
thus this needs to be increased to maximum size.
Changing the value to 0x7f, which is the maximum for 7 bits field.

Subject: [PATCH 133/247] dmaengine: at_xdmac: add support for sama7g5 based
at_xdmac
SAMA7G5 SoC uses a slightly different variant of the AT_XDMAC.
Added support by a new compatible and a layout struct that copes
to the specific version considering the compatible string.
Only the differences in register map are present in the layout struct.
I reworked the register access for this part that has the differences.
Also the Source/Destination Interface bits are no longer valid for this
variant of the XDMAC. Thus, the layout also has a bool for specifying
whether these bits are required or not.

Subject: [PATCH 134/247] dmaengine: at_xdmac: add AXI priority support and
recommended settings
The sama7g5 version of the XDMAC supports priority configuration and
outstanding capabilities.
Add defines for the specific registers for this configuration, together
with recommended settings.
However the settings are very different if the XDMAC is a mem2mem or a
per2mem controller.
Thus, we need to differentiate according to device tree property.

From 982347f757b85ef526afaf243867ddd515475e1b Mon Sep 17 00:00:00 2001

Date: Mon, 4 Jan 2021 10:38:02 +0000
Subject: [PATCH 135/247] net: macb: Correct usage of MACB_CAPS_CLK_HW_CHG flag
A new flag MACB_CAPS_CLK_HW_CHG was added and all callers of
macb_set_tx_clk were gated on the presence of this flag.
- if (!clk)
+ if (!bp->tx_clk || !(bp->caps & MACB_CAPS_CLK_HW_CHG))
However the flag was not added to anything other than the new
sama7g5_gem, turning that function call into a no op for all other
systems. This breaks the networking on Zynq.
The commit message adding this states: a new capability so that
macb_set_tx_clock() to not be called for IPs having this
capability
This strongly implies that present of the flag was intended to skip
the function not absence of the flag. Update the if statement to
this effect, which repairs the existing users.
Fixes: daafa1d33cc9 ("net: macb: add capability to not set the clock rate")

Subject: [PATCH 139/247] drivers: soc: atmel: add per soc id and version match
masks
SAMA7G5 has different masks for chip ID and chip version on CIDR
register compared to previous AT91 SoCs. For this the commit adapts
the code for SAMA7G5 addition by introducing 2 new members in
struct at91_soc and fill them properly and also preparing the
parsing of proper DT binding.

Subject: [PATCH 144/247] ASoC: atmel-pdc: Use managed DMA buffer allocation
Instead of manually managing its DMA buffers using
dma_{alloc,free}_coherent() lets the sound core take care of this using
managed buffers.
On one hand this reduces the amount of boiler plate code, but the main
motivation for the change is to use the shared code where possible. This
makes it easier to argue about correctness and that the code does not
contain subtle bugs like data leakage or similar.

Subject: [PATCH 146/247] pinctrl: at91-pio4: add support for slew-rate
SAMA7G5 supports slew rate configuration. Adapt the driver for this.
For output switching frequencies lower than 50MHz the slew rate needs to
be enabled. Since most of the pins on SAMA7G5 fall into this category
enabled the slew rate by default.

There is no usrio config defined for default gem config leading to
a kernel panic devices that don't define a data. This issue can be
reprdouced with microchip polar fire soc where compatible string
is defined as "cdns,macb".

The latest I2S-MCC available in SAMA7G5 supports multi-channel for I2S and
Left-Justified formats. For this, the new version uses 8 (4 * 2) input and
output pins, with each pin being responsible for 2 channels. This sums up
to a total of 8 channels for synchronous capture and playback.

Subject: [PATCH 152/247] ASoC: mchp-i2s-mcc: Add support to select TDM pins
SAMA7G5's I2S-MCC has 4 pairs of DIN/DOUT pins. Since TDM only uses a
single pair of pins for synchronous capture and playback, the controller
needs to be told which of the pair is connected. This can be mentioned
using the "microchip,tdm-data-pair" property from DT. The property is
optional, useful only if TDM is used. If it's missing, DIN/DOUT 0 pins
will be used by default.

Subject: [PATCH 154/247] pinctrl: at91-pio4: Fix slew rate disablement
The slew rate was enabled by default for each configuration of the
pin. In case the pin had more than one configuration, even if
we set the slew rate as disabled in the device tree, the next pin
configuration would set again the slew rate enabled by default,
overwriting the slew rate disablement.
Instead of enabling the slew rate by default for each pin configuration,
enable the slew rate by default just once per pin, regardless of the
number of configurations. This way the slew rate disablement will also
work for cases where pins have multiple configurations.

Date: Fri, 23 Apr 2021 16:47:42 +0200
Subject: [PATCH 155/247] media: atmel: properly get pm_runtime
There are several issues in the way the atmel driver handles
pm_runtime_get_sync():
- it doesn't check return codes;
- it doesn't properly decrement the usage_count on all places;
- it starts streaming even if pm_runtime_get_sync() fails.
- while it tries to get pm_runtime at the clock enable logic,
it doesn't check if the operation was suceeded.
Replace all occurrences of it to use the new kAPI:
pm_runtime_resume_and_get(), which ensures that, if the
return code is not negative, the usage_count was incremented.
With that, add additional checks when this is called, in order
to ensure that errors will be properly addressed.

Subject: [PATCH 156/247] media: atmel: atmel-isc: Remove redundant assignment
to i
Variable i is being assigned a value however the assignment is
never read, so this redundant assignment can be removed.
Clean up the following clang-analyzer warning:
drivers/media/platform/atmel/atmel-isc-base.c:975:2: warning: Value
stored to 'i' is never read [clang-analyzer-deadcode.DeadStores].

Subject: [PATCH 158/247] media: atmel: atmel-isc: specialize driver name
constant
The driver name constant must defined based on product driver, thus moving
the constant directly where it's required. This will allow each ISC based
product to define it's own name.

Subject: [PATCH 159/247] media: atmel: atmel-isc: add checks for limiting
frame sizes
When calling the subdev, certain subdev drivers will overwrite the
frame size and adding sizes which are beyond the ISC's capabilities.
Thus we need to ensure the frame size is cropped to the maximum caps.

Subject: [PATCH 162/247] media: atmel: atmel-isc: extract CSC submodule config
into separate function
The CSC submodule is a part of the atmel-isc pipeline, and stands for
Color Space Conversion. It is used to apply a matrix transformation to
RGB pixels to convert them to the YUV components.
The CSC submodule should be initialized in the product specific driver
as it's product specific. Other products can implement it differently.

Subject: [PATCH 165/247] media: atmel: atmel-isc: extract CBC submodule config
into separate function
The CBC submodule is a part of the atmel-isc pipeline, and stands for
Contrast Brightness Control. It is used to apply gains and offsets to the
luma (Y) and chroma (U, V) components of the YUV elements.
The CBC submodule should be initialized in the product specific driver
as it's product specific. Other products can implement it differently

The RLP submodule is a part of the atmel-isc pipeline, and stands for
Rounding,Limiting and Packaging. It used to extract specific data from the
ISC pipeline. For example if we want to output greyscale 8 bit, we would
use limiting to 8 bits, and packaging to Luma component only.
Add rlp to the reg offsets struct.
This will allow different products to have a different reg offset for this
particular module.

Subject: [PATCH 174/247] media: atmel: atmel-isc: extend pipeline with extra
modules
Newer ISC pipelines have the additional modules of
Defective Pixel Correction -> DPC itself,
Defective Pixel Correction -> Green Disparity Correction (DPC_GDC)
Defective Pixel Correction -> Black Level Correction (DPC_BLC)
Vertical and Horizontal Scaler -> VHXS
Some products have this full pipeline (sama7g5), other products do not (sama5d2)
Add the modules to the isc base, and also extend the register range to include
the modules.

Subject: [PATCH 175/247] media: atmel: atmel-isc: add CC initialization
function
The CC submodule is a part of the atmel-isc pipeline, and stands for
Color Correction. It is used to apply gains and offsets to the
chroma (U, V) components of the YUV elements.
Implement the CC submodule initialization, as a product
specific function, which currently configures the neutral point in color
correction.

Subject: [PATCH 177/247] media: atmel: atmel-isc: create callback for DPC
submodule product specific
The DPC submodule is a part of the atmel-isc pipeline, and stands for
Defective Pixel Correction. Its purpose is to detect defective pixels and
correct them if possible with the help of adjacent pixels.
Create a product specific callback for initializing the DPC submodule
of the pipeline.
For sama5d2 product, this module does not exist, thus this function is a noop.

Subject: [PATCH 181/247] media: atmel: atmel-isc: create an adapt pipeline
callback for product specific
Once the pipeline is set in the base code, create a callback that will adapt
the ISC pipeline to each product.
Create the adapt_pipeline callback that will be used in this fashion.

Subject: [PATCH 190/247] media: atmel: fix build when ISC=m and XISC=y
Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in
(or viceversa) causes build errors:
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete':
atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module'

or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module'
This is caused by the file atmel-isc-base.c which is common code between
the two drivers.
The solution is to create another Kconfig symbol that is automatically
selected and generates the module atmel-isc-base.ko. This module can be
loaded when both drivers are modules, or built-in when at least one of them
is built-in.

Subject: [PATCH 193/247] media: atmel: atmel-sama5d2-isc: fix YUYV format
SAMA5D2 does not have the YCYC field for the RLP (rounding, limiting,
packaging) module.
The YCYC field is supposed to work with interleaved YUV formats like YUYV.
In SAMA5D2, we have to use YYCC field, which is used for both planar
formats like YUV420 and interleaved formats like YUYV.
Fix the according rlp callback to replace the generic YCYC field (which
makes more sense from a logical point of view) with the required YYCC
field.

Subject: [PATCH 198/247] ARM: at91: pm: move the setup of soc_pm.bu->suspended
Move the setup of soc_pm.bu->suspended in platform_suspend::begin
function so that the PMC code in charge with clocks suspend/resume
to differentiate b/w standard PM mode and backup mode.

Subject: [PATCH 200/247] ARM: at91: pm: check for different controllers in
at91_pm_modes_init()
at91_pm_modes_init() checks for proper nodes in device tree and maps
them accordingly. Up to SAMA7G5 all AT91 SoCs had the same mapping
b/w power saving modes and different controllers needed in the
final/first steps of suspend/resume. SAMA7G5 is not aligned with the
old SoCs thus the code is adapted for this. This patch prepares
the field for next commits.
