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 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.

Support for IPQ8064 tsens driver. The driver works
with the thermal framework. The driver overrides the
following fucntionalities:
1. Get current temperature.
2. Get/Set trip temperatures.
3. Enabled/Disable trip points.
4. ISR for threshold generated interrupt.
5. Notify userspace when trip points are hit.

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.

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.

From 13bec8d49bdf10aab4e1570ef42417f6bfbb6126 Mon Sep 17 00:00:00 2001
From: Ajay Kishore <akisho@codeaurora.org>
Date: Fri, 27 Mar 2020 23:32:08 +0100
Subject: pinctrl: qcom: use scm_call to route GPIO irq to Apps
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.

Subject: watchdog: qcom-wdt: disable pretimeout on timer platform
Some platform like ipq806x doesn't support pretimeout and define
some interrupts used by qcom,msm-timer. Change the driver to check
and use pretimeout only on qcom,kpss-wdt as it's the only platform
that actually supports it.

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: phy: qualcomm: add qcom ipq806x dwc usb phy driver
This has lost in the original push for the dwc3 qcom driver.
This is needed for ipq806x SoC as without this the usb ports
doesn't work at all.

From 3d7b0ca5300bd01b176f2b4c10e173db802560d8 Mon Sep 17 00:00:00 2001

Subject: phy: qualcomm: fix setting of tx_deamp_3_5db when device property
read fails
Currently when reading of the device property for "qcom,tx-deamp_3_5db"
fails the default is being assigned incorrectly to phy_dwc3->rx_eq. This
looks like a copy-n-paste error and in fact should be assigning the
default instead to phy_dwc3->tx_deamp_3_5db
Addresses-Coverity: ("Copy-paste error")
Fixes: ef19b117b834 ("phy: qualcomm: add qcom ipq806x dwc usb phy driver")
