Subject: [PATCH v3 13/18] ARM: dts: qcom: add opp table for cpu and l2 for
ipq8064
Add opp table for cpu and l2 cache. While the current cpufreq is
the generic one that doesn't scale the L2 cache, we add the l2
cache opp anyway for the sake of completeness. This will be handy in the
future when a dedicated cpufreq driver is introduced for krait cores
that will correctly scale l2 cache with the core freq.
Opp-level is set based on the logic of
0: idle level
1: normal level
2: turbo level

Subject: [PATCH 1/4] devfreq: qcom: Add L2 Krait Cache devfreq scaling driver
Qcom L2 Krait CPUs use the generic cpufreq-dt driver and doesn't actually
scale the Cache frequency when the CPU frequency is changed. This
devfreq driver register with the cpu notifier and scale the Cache
based on the max Freq across all core as the CPU cache is shared across
all of them. If provided this also scale the voltage of the regulator
attached to the CPU cache. The scaling logic is based on the CPU freq
and the 3 scaling interval are set by the device dts.

Subject: [PATCH 4/9] clk: qcom: krait-cc: register REAL qsb fixed clock
With some tools it was discovered the real frequency of the qsb fixed
clock. While not 100% correct it's still better than using 1 as a dummy
frequency.
Correctly register the qsb fixed clock with the frequency of 225 MHz
instead of 1.

Subject: [PATCH 9/9] clk: qcom: krait-cc: rework mux reset logic and reset
hfpll
Rework and clean mux reset logic.
Compact it to a for loop to handle both CPU and L2 in one place.
Move hardcoded aux_rate to define and add a new hfpll_rate value to
reset hfpll settings.
Change logic to now reset the hfpll to the lowest value of 600 Mhz and
then restoring the previous frequency. This permits to reset the hfpll if
the primary mux was set to source out of the secondary mux.

Subject: [PATCH v2 4/4] clk: qcom: gcc-ipq806x: remove cc_register_board for
pxo and cxo
Now that these clock are defined as fixed clk in dts, we can drop the
register_board_clk for cxo_board and pxo_board in gcc_ipq806x_probe.

Subject: [PATCH v2 1/2] ARM: decompressor: support memory start validation for
appended DTB
There is currently a problem with a very specific sets of kernel config
and AUTO_ZRELADDR.
For the most common case AUTO_ZRELADDR check the PC register and
calculate the start of the physical memory. Then fdt_check_mem_start is
called to make sure the detected value makes sense by comparing it with
what is present in DTB in the memory nodes and if additional fixup are
required with the use of linux,usable-memory-range in the chosen node to
hardcode usable memory range in case some reserved space needs to be
addressed. With the help of this function the right address is
calculated and the kernel correctly decompress and loads.
Things starts to become problematic when in the mix,
CONFIG_ARM_APPENDED_DTB is used. This is a particular kernel config is
used when legacy systems doesn't support passing a DTB directly and a
DTB is appended at the end of the image.
In such case, fdt_check_mem_start is skipped in AUTO_ZRELADDR iteration
as the appended DTB can be augumented later with ATAGS passed from the
bootloader (if CONFIG_ARM_ATAG_DTB_COMPAT is enabled).
The main problem and what this patch address is the fact that
fdt_check_mem_start is never called later when the appended DTB is
augumented, hence any fixup and validation is not done making AUTO_ZRELADDR
detection inconsistent and most of the time wrong.
Add support in head.S for this by checking if AUTO_ZRELADDR is enabled
and calling fdt_check_mem_start with the appended DTB and the augumented
values permitting legacy device to provide info in DTB instead of
disabling AUTO_ZRELADDR and hardcoding the physical address offsets.

Subject: [PATCH] ARM: decompressor: support for ATAGs rootblock parsing
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.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.
