bcm27xx: update 6.1 patches from RPi foundation

Browse Source 
Sync 6.1 patches with the RPi foundation.
Since rpi-6.6.y is now the main branch of the RPi foundation, there won't be
any new patches for linux 6.1.

Subject: [PATCH] drm/v3d: Improve MMU support for larger pages
The built-in MMU driver went most of the way towards supporting larger
kernel pages, but dropped the ball when it comes to calculating indexes
into the page table. Fix it.

Subject: [PATCH] i2c: designware: Look for *CNT values in DT
The i2c-designware driver supports reading precise timing values from
ACPI, but the Device Tree support relies on a combination of standard
rise and fall times and hard-coded minimum timings. The result of this
is that it is difficult to get optimum timings, particularly given that
the values are bus speed-specific and only one set can be stored in
DT at a time.
Add support for initialisation from DT that is similar to that for
ACPI.

Subject: [PATCH 1247/1295] drm/vc4: Optimise vc4_hvs_dlist_free_work to only

vc4_hvs_dlist_free_work was iterating through the list of stale
dlist entries and reading the frame count and active flags from
the hardware for each one.
Read the frame count and active flags once, and then use the
cached value in the loop.

Subject: [PATCH 1248/1295] drm/vc4: Flush stale dlist entries if allocation
fails
This is largely for debug at present.
For reasons unknown we are not getting the end of frame interrupts
that should trigger a sweep of stale dlist entries.
On allocation failure clear out ALL stale entries, and retry the
allocation. Log the interrupt status so we have debug regarding
whether the HVS believes the interrupt is enabled.

Subject: [PATCH 1252/1295] Improvement on backup-switchover-mode overlay value
definitions (#5884)
For the RV3028 RTC, the definitions for its `backup-switchover-mode` overlay
were not intelligible neither complete/exhaustive.
Accordingly to the https://github.com/raspberrypi/linux/issues/2912#issuecomment-477670051
these one here proposed should be correct.
`/boot/config.txt` should be as a configuration example, for rv3028, on a
Uputronics GPS Extension HAT:
# For GPS Expansion Board from Uputronics
dtparam=i2c_arm=on
dtoverlay=i2c-rtc,rv3028,backup-switchover-mode=3
dtoverlay=pps-gpio,gpiopin=18
init_uart_baud=115200
From my tests (`sudo rmmod rtc_rv3028 && sudo i2cget -y 1 0x52 0x37`):
`Default from factory`: `0x10`
`Mode 0`: `0x10`
`Mode 1`: `0x14`
`Mode 2`: `0x18`
`Mode 3`: `0x1c`
`Mode 3`: `0x1c` is consistent with the manufacturer configuration script: http://store.uputronics.com/files/configure-rv3028.sh

Subject: [PATCH 1260/1295] iommu/bcm2712: don't allow building as module
Since bcm2712-iommu{,-cache}.c doesn't have usual module descriptors
such as `MODULE_LICENSE`, configuring this as 'M' fails the build with
`ERROR: modpost: missing MODULE_LICENSE() in <...>/bcm2712-iommu.o`.
Since it seems like the code is not intended to be built as a module
anyway (it registers the driver with `builtin_platform_driver()`), don't
allow building this code as a module.

Subject: [PATCH 1261/1295] drm/rp1: depends on, instead of select, MFD_RP1
According to kconfig-language.txt [1], select should be used only for
"non-visible symbols ... and for symbols with no dependencies". Since
MFD_RP1 both is visible and has a dependency, "select" should not be
used and "depends on" should be used instead.
In particular, this fixes the build of this kernel tree on NixOS, where
its kernel config system will try to answer 'M' to as many config as
possible.

Subject: [PATCH 1262/1295] Update touch PiTFT overlays
Expose the invert and swap touch parameters on 2.8" and 3.5" resistive touchscreens. Add
the DRM parameter to the PiTFT 2.2" and 2.8" Capacitive overlay in the same
way it is on the resistive overlays. Change the DRM driver to `adafruit,yx240qv29`
because the rotations are consistent with the FBTFT Driver. Fix the override size parameters
on the 2.8" capacitive PiTFT.

Subject: [PATCH 1264/1295] ARM: dts: rp1: Add a safe I2C SDA hold time
Failing to set a reasonable SDA hold time can cause SDA to change too
close to the falling edge of SCL. 300ns is the recommended minimum
interval between the two at 100kHz and 400kHz, and also seems to
work at 1MHz, so use that.

The former code did not adjust the physical sample width when
in clock consumer mode and has taken the fixed 32 bit default.
This has caused the audio to be played at half its frequency due to
the fixed bclk_ratio of 64.

Subject: [PATCH 1266/1295] ASoC: adds support for AMP4 Pro to the DAC Plus
driver
The AMP4 Pro is a I2S master mode capable amplifier with
clean onboard clock generators.
We can share the card driver between TAS575x amplifiers
and the PCM512x DACs as they are SW compatible.
From a HW perspective though we need to limit the sample
rates to the standard audio rates to avoid running the
onboard clocks through the PLL. Using the PLL would require
even a different HW.
DAI/stream name are also set accordingly to allow the user
a convenient identification of the soundcard
Needs the pcm512x driver with TAS575x support (already in
upstream kernel).

Subject: [PATCH 1271/1295] drivers: media: cfe: Increase default size of
embedded buffer
Increase the size of the default embedded buffer to 16k. This is done to
match what is advertised by the IMX219 driver and workaround a problem
where the embedded stream is not actually used. Without full streams API
support, the media pipeline validation will fail in these circumstances.

Subject: [PATCH 1279/1295] drm/v3d: Enable V3D to use different PAGE_SIZE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, the V3D driver uses PAGE_SHIFT over the assumption that
PAGE_SHIFT = 12, as the PAGE_SIZE = 4KB. But, the RPi 5 is using
PAGE_SIZE = 16KB, so the MMU PAGE_SHIFT is different than the system's
PAGE_SHIFT.
Enable V3D to be used in system's with any PAGE_SIZE by making sure that
everything MMU-related uses the MMU page shift.

Subject: [PATCH 1280/1295] overlays: adau1977-adc: Replace use of i2c label
The label 'i2c' is no longer created by the firmware - i2c_arm or
i2c1 should be used instead. Replace the last occurrence of &i2c with
&i2c1.

Subject: [PATCH 1285/1295] vc4/hvs: Fix lbm size calculation for yuv (#6012)
The code was reducing the number of components by one when we were not
blending with alpha. But that only makes sense if the components include
alpha.
For YUV, we were reducing the number of components for Y from one to zero
which resulted in no lbm space being allocated.

Subject: [PATCH 1290/1295] Overlays:Add specific clk-producer/-consumer
overlays for Hifiberry DAC+
As the easy switching of the I2S module bewteen clock producer/consumer
on the PI5 is not possible, two specific DT-overlays are introduced.
The DAC+PRO boards with onboard clocks use the -PRO overlay, the boards
without oscillators the -STD version.
The "hifiberry-dacplus,slave" parameter in the -STD overlay disables
the automatic clock detection inside the hifiberry-dacplus driver.
The former hifiberry-dacplus overlay is kept for compatibility but
will be deprecated.

Subject: [PATCH 1293/1295] overlays: Sets i2s_clk_producer as default for
Hifiberry DACplusADC
As we have never released a (standard) DACplusADC board with onboard
clocks, we can simply use a fixed setup avoiding incompatibilities
with Pi5 during driver init. Setting 'hifiberry-dacplusadc,slave' in
the overlays disables the failing clock probing mechanism.
Removes 'slave' parameter description from README which is still
supported but not needed.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
Allow trigger-mode to be overridden using device tree so that it can be
set per camera. Previously the mode could only be changed using a module
parameter, which would then affect all cameras.
