Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
|
||||
|
||||
Original patch from Andy Gross.
|
||||
|
||||
This patch removes the crci information from the dma
|
||||
channel property. At least one client device requires
|
||||
using more than one CRCI value for a channel. This does
|
||||
not match the current binding and the crci information
|
||||
needs to be removed.
|
||||
|
||||
Instead, the client device will provide this information
|
||||
via other means.

Subject: [PATCH 02/69] dmaengine: Add ADM driver
|
||||
|
||||
Original patch by Andy Gross.
|
||||
|
||||
Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
|
||||
controller found in the MSM8x60 and IPQ/APQ8064 platforms.
|
||||
|
||||
The ADM supports both memory to memory transactions and memory
|
||||
to/from peripheral device transactions. The controller also provides flow
|
||||
control capabilities for transactions to/from peripheral devices.
|
||||
|
||||
The initial release of this driver supports slave transfers to/from peripherals
|
||||
and also incorporates CRCI (client rate control interface) flow control.

Subject: [PATCH 31/69] mtd: add SMEM parser for QCOM platforms
|
||||
|
||||
On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
|
||||
used to store partition layout. This new parser can now be used to read
|
||||
SMEM and use it to register an MTD layout according to its content.

Subject: [PATCH 33/69] ARM: qcom: automatically select PCI_DOMAINS if PCI is
|
||||
enabled
|
||||
|
||||
If multiple PCIe devices are present in the system, the kernel will
|
||||
panic at boot time when trying to scan the PCI buses. This happens on
|
||||
IPQ806x based platforms, which has 3 PCIe ports.
|
||||
|
||||
Enabling this option allows the kernel to assign the pci-domains
|
||||
according to the device-tree content. This allows multiple PCIe
|
||||
controllers to coexist in the system.

Subject: [PATCH 01/12] ARM: Add Krait L2 register accessor functions
|
||||
|
||||
Krait CPUs have a handful of L2 cache controller registers that
|
||||
live behind a cp15 based indirection register. First you program
|
||||
the indirection register (l2cpselr) to point the L2 'window'
|
||||
register (l2cpdr) at what you want to read/write. Then you
|
||||
read/write the 'window' register to do what you want. The
|
||||
l2cpselr register is not banked per-cpu so we must lock around
|
||||
accesses to it to prevent other CPUs from re-pointing l2cpdr
|
||||
underneath us.
|
||||

Subject: [PATCH 02/12] clk: qcom: Add support for High-Frequency PLLs (HFPLLs)
|
||||
|
||||
HFPLLs are the main frequency source for Krait CPU clocks. Add
|
||||
support for changing the rate of these PLLs.

Subject: [PATCH 03/12] clk: qcom: Add HFPLL driver
|
||||
|
||||
On some devices (MSM8974 for example), the HFPLLs are
|
||||
instantiated within the Krait processor subsystem as separate
|
||||
register regions. Add a driver for these PLLs so that we can
|
||||
provide HFPLL clocks for use by the system.

Subject: [PATCH 07/12] clk: qcom: Add support for Krait clocks
|
||||
|
||||
The Krait clocks are made up of a series of muxes and a divider
|
||||
that choose between a fixed rate clock and dedicated HFPLLs for
|
||||
each CPU. Instead of using mmio accesses to remux parents, the
|
||||
Krait implementation exposes the remux control via cp15
|
||||
registers. Support these clocks.

The ACC and GCC regions present in KPSSv1 contain registers to
|

control clocks and power to each Krait CPU and L2. For CPUfreq
|
||||
purposes probe these devices and expose a mux clock that chooses
|
||||
between PXO and PLL8.

Subject: [PATCH 12/12] clk: qcom: Add safe switch hook for krait mux clocks
|
||||
|
||||
When the Hfplls are reprogrammed during the rate change,
|
||||
the primary muxes which are sourced from the same hfpll
|
||||
for higher frequencies, needs to be switched to the 'safe
|
||||
secondary mux' as the parent for that small window. This
|
||||
is done by registering a clk notifier for the muxes and
|
||||
switching to the safe parent in the PRE_RATE_CHANGE notifier
|
||||
and back to the original parent in the POST_RATE_CHANGE notifier.

The variables are local to the source and do not

need to be in global scope, so make them static.

Subject: [PATCH] cpufreq: qcom: Re-organise kryo cpufreq to use it for other
|
||||
nvmem based qcom socs
|
||||
|
||||
The kryo cpufreq driver reads the nvmem cell and uses that data to
|
||||
populate the opps. There are other qcom cpufreq socs like krait which
|
||||
does similar thing. Except for the interpretation of the read data,
|
||||
rest of the driver is same for both the cases. So pull the common things
|
||||
out for reuse.

Subject: [PATCH] cpufreq: qcom: Refactor the driver to make it easier to
|
||||
extend
|
||||
|
||||
Refactor the driver to make it easier to extend in a later commit.
|
||||
|
||||
Create a driver struct to collect all common resources, in order to make
|
||||
it easier to free up all common resources.
|
||||
Create a driver match_data struct to make it easier to extend the driver
|
||||
with support for new features that might only be supported on certain SoCs.

|

|
||||
In Certain QCOM SoCs like ipq8064, apq8064, msm8960, msm8974
|
||||
that has KRAIT processors the voltage/current value of each OPP
|
||||
varies based on the silicon variant in use.
|
||||
|
||||
The required OPP related data is determined based on
|
||||
the efuse value. This is similar to the existing code for
|
||||
kryo cores. So adding support for krait cores here.

Subject: [PATCH v5 1/4] PM / OPP: Support adjusting OPP voltages at runtime
|
||||
Date: Wed, 16 Oct 2019 16:57:53 +0200
|
||||
Message-ID: <20191016145756.16004-2-s.nawrocki@samsung.com> (raw)
|
||||
In-Reply-To: <20191016145756.16004-1-s.nawrocki@samsung.com>
|
||||
|
||||
From: Stephen Boyd <sboyd@codeaurora.org>
|
||||
|
||||
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
|
||||
employed to optimize the operating voltage of a device. At a
|
||||
given frequency, the hardware monitors dynamic factors and either
|
||||
makes a suggestion for how much to adjust a voltage for the
|
||||
current frequency, or it automatically adjusts the voltage
|
||||
without software intervention. Add an API to the OPP library for
|
||||
the former case, so that AVS type devices can update the voltages
|
||||
for an OPP when the hardware determines the voltage should
|
||||
change. The assumption is that drivers like CPUfreq or devfreq
|
||||
will register for the OPP notifiers and adjust the voltage
|
||||
according to suggestions that AVS makes.
|
||||
|
||||
This patch is derived from [1] submitted by Stephen.

Subject: [PATCH 52/69] PM / OPP: Update the voltage tolerance when adjusting
|
||||
the OPP
|
||||
|
||||
When the voltage is adjusted, the voltage tolerance is not updated.
|
||||
This can lead to situations where the voltage min value is greater
|
||||
than the voltage max value. The final result is triggering a BUG()
|
||||
in the regulator core.
|
||||
Fix this by updating the voltage tolerance values too.

Subject: [PATCH 54/69] cpufreq-dt: Handle OPP voltage adjust events
|
||||
|
||||
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
|
||||
employed to optimize the operating voltage of a device. At a
|
||||
given frequency, the hardware monitors dynamic factors and either
|
||||
makes a suggestion for how much to adjust a voltage for the
|
||||
current frequency, or it automatically adjusts the voltage
|
||||
without software intervention.
|
||||
|
||||
In the former case, an AVS driver will call
|
||||
dev_pm_opp_modify_voltage() and update the voltage for the
|
||||
particular OPP the CPUs are using. Add an OPP notifier to
|
||||
cpufreq-dt so that we can adjust the voltage of the CPU when AVS
|
||||
updates the OPP.

Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
|
||||
|
||||
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
|
||||
on most ARM architectures. This automatically calculate ZRELADDR by
|
||||
masking PHYS_OFFSET with 0xf8000000.
|
||||
|
||||
However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
|
||||
network accelerators, and the bootloader removes this section from the
|
||||
layout passed from the ATAGS (when used).
|
||||
|
||||
For newer bootloader, when DT is used, this is not a problem, we just
|
||||
reserve this memory in the device tree. But if the bootloader doesn't
|
||||
have DT support, then ATAGS have to be used. In this case, the ARM
|
||||
decompressor will position the kernel in this low mem, which will not be
|
||||
in the RAM section mapped by the bootloader, which means the kernel will
|
||||
freeze in the middle of the boot process trying to map the memory.
|
||||
|
||||
As a work around, this patch allows disabling AUTO_ZRELADDR when
|
||||
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
|
||||
which don't support device-tree, which is the case on certain early
|
||||
IPQ806x based designs.

Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
|
||||
|
||||
Provide support for adding configurable high and
|
||||
configurable low trip temperatures. An interrupts is
|
||||
also triggerred when these trip points are hit. The
|
||||
interrupts can be activated or deactivated from sysfs.
|
||||
This functionality is made available only if
|
||||
CONFIG_THERMAL_WRITABLE_TRIPS is defined.

Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
|
||||
|
||||
The command-line arguments provided by the boot loader will be
|
||||
appended to a new device tree property: bootloader-args.
|
||||
If there is a property "append-rootblock" in DT under /chosen
|
||||
and a root= option in bootloaders command line it will be parsed
|
||||
and added to DT bootargs with the form: <append-rootblock>XX.
|
||||
Only command line ATAG will be processed, the rest of the ATAGs
|
||||
sent by bootloader will be ignored.
|
||||
This is usefull in dual boot systems, to get the current root partition
|
||||
without afecting the rest of the system.

|

|

pcie_phy_clk is generated for PCIe controller itself and the
|
||||
GCC controls its branch operation. This error is coming since
|
||||
the assert operations turn off the parent clock before branch
|
||||
clock. Now this patch moves clk_disable_unprepare before assert
|
||||
operations.
|
||||
|
||||
Similarly, during probe function, the clock branch operation
|
||||
should be done after dessert operation. Currently, it does not
|
||||
generate any error since bootloader enables the pcie_phy_clk
|
||||
but the same error is coming during probe, if bootloader
|
||||
disables pcie_phy_clk.

|
||||
For IPQ806x targets, TZ protects the registers that are used to
|
||||
configure the routing of interrupts to a target processor.
|
||||
To resolve this, this patch uses scm call to route GPIO interrupts
|
||||
to application processor. Also the scm call interface is changed.

This patch adds the gpio-ranges property to almost all of
|
||||
the Qualcomm ARM platforms that utilize the pinctrl-msm
|
||||
framework.
|
||||
|
||||
The gpio-ranges property is part of the gpiolib subsystem.
|
||||
As a result, the binding text is available in section
|
||||
"2.1 gpio- and pin-controller interaction" of
|
||||
Documentation/devicetree/bindings/gpio/gpio.txt
|
||||
|
||||
For more information please see the patch titled:
|
||||
"pinctrl: msm: fix gpio-hog related boot issues" from
|
||||
this series.

To help with git bisect, the DT update patch has been intentionally
|
||||
placed after the "pinctrl: msm: fix gpio-hog related boot issues".
|
||||
Otherwise - if the order was reveresed - and bisect decides to split
|
||||
between these two patches, the gpiochip_add_pin_ranges() function
|
||||
will be executed twice with the same parameters for the same pinctrl.
