[ Upstream commit 7045465500e465b09f09d6e5bdc260a9f1aab97b ]
Fix invalid usage of a list_for_each_entry cursor in
clk_notifier_unregister(). When list is empty or if the list
is completely traversed (without breaking from the loop on one
of the entries) then the list cursor does not point to a valid
entry and therefore should not be used. The patch fixes a logical
bug that hasn't been seen in pratice however it is analogus
to the bug fixed in clk_notifier_register().
The issue was dicovered when running 5.12-rc1 kernel on x86_64

[ Upstream commit 148ddaa89d4a0a927c4353398096cc33687755c1 ]
While picking commit a8cd989e1a57 ("mmc: sdhci-msm: Warn about
overclocking SD/MMC") back to my tree I was surprised that it was
reporting warnings. I thought I fixed those! Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it). The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh. Let's fix my dumb mistake.
Now both SD and eMMC have floor for the "apps" clock.
This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
These were the messages I was seeing at boot:
mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz

The GPU GX GDSC has GPU_GX_BCR reset and gfx3d_clk CXC, as stated
on downstream kernels (and as verified upstream, because otherwise
random lockups happen).
Also, add PWRSTS_RET and NO_RET_PERIPH: also as found downstream,
and also as verified here, to avoid GPU related lockups it is
necessary to force retain mem, but *not* peripheral when enabling
this GDSC (and, of course, the inverse on disablement).
With this change, the GPU finally works flawlessly on my four
different MSM8998 devices from two different manufacturers.

In some rare occasions, we want to only set the RETAIN_MEM bit, but
not the RETAIN_PERIPH one: this is seen on at least SDM630/636/660's
GPU-GX GDSC, where unsetting and setting back the RETAIN_PERIPH bit
will generate chaos and panics during GPU suspend time (mainly, the
chaos is unaligned access).
For this reason, introduce a new NO_RET_PERIPH flag to the GDSC
driver to address this corner case.

[ Upstream commit 292f75ecff07e8a07fe2e3e19b4b567d0b698842 ]
All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
and not generic alphas: this was producing bad effects over the entire
clock tree of MSM8998, where any GPLL child clock was declaring a false
clock rate, due to their parent also showing the same.
The issue resides in the calculation of the clock rate for the specific
Alpha PLL type, where Fabia has a different register layout; switching
the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
(calculation) reading. While at it, also make these PLLs fixed since
their rate is supposed to *never* be changed while the system runs, as
this would surely crash the entire SoC.
Now all the children of all the PLLs are also complying with their
specified clock table and system stability is improved.

I would repeat the same commit message that was in commit 5e4b7e82d497
("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks") but it seems
silly to do so when you could just go read that commit.
NOTE: this is actually extra terrible because we're missing the 50 MHz
rate in the table (see the next patch AKA ("clk: qcom: gcc-sc7180: Add
50 MHz clock rate for SDC2")). That means then when you run an older
SD card it'll try to clock it at 100 MHz when it's only specced to run
at 50 MHz max. As you can probably guess that doesn't work super
well.

The R-Car V3U clock driver defines the R and OSC clocks using R-Car Gen3
clock types. However, The R-Car V3U clock driver does not use the R-Car
Gen3 clock driver core, hence registering the R and OSC clocks fails:
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock osc: -22
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock r: -22
Fix this by introducing clock definition macros specific to R-Car V3U.
Note that rcar_r8a779a0_cpg_clk_register() already handled the related
clock types. Drop the now unneeded include of rcar-gen3-cpg.h.

The R9A06G032 clock driver uses an array of packed structures to reduce
kernel size. However, this array contains pointers, which are no longer
aligned naturally, and cannot be relocated on PPC64. Hence when
compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g.
PowerPC allyesconfig), the following warnings are produced:
WARNING: 136 bad relocations
c000000000616be3 R_PPC64_UADDR64 .rodata+0x00000000000cf338
c000000000616bfe R_PPC64_UADDR64 .rodata+0x00000000000cf370
...
Fix this by dropping the __packed attribute from the r9a06g032_clkdesc
definition, trading a small size increase for portability.
This increases the 156-entry clock table by 1 byte per entry, but due to
the compiler generating more efficient code for unpacked accesses, the
net size increase is only 76 bytes (gcc 9.3.0 on arm32).

This issue can be reproduced by having a kernel config with
CONFIG_IMX_MBOX=m and CONFIG_MXC_CLK_SCU=m. It's caused by the Makefile
wanting to build clk-scu.o and clk-imx8qxp.o as different targets but
that doesn't work (e.g. MXC_CLK_SCU = y while CLK_IMX8QXP = n)
"obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o clk-imx-lpcg-scu.o
clk-imx-scu-$(CONFIG_CLK_IMX8QXP) += clk-scu.o clk-imx8qxp.o"
Having MXC_CLK_SCU=y/m while CLK_IMX8QXP=n will cause a linker problem
like below:
LD [M] drivers/clk/imx/clk-imx-scu.o
arm-poky-linux-gnueabi-ld: no input files
Make MXC_CLK_SCU be un-selectable by users so it can only be selected by
the CLK_IMX8QXP option, ensuring the two symbols are built together.
Drop COMPILE_TEST too because this option isn't selectable anymore. We
can remove it from MXC_CLK_SCU because CLK_IMX8QXP selects MXC_CLK_SCU
which already has COMPILE_TEST.

noc/axi/ahb are bus clk, not peripheral clk.
Since peripheral clk has a limitation that for peripheral clock slice,
IP clock slices must be stopped to change the clock source.
However if the bus clk is marked as critical clk peripheral, the
assigned clock parent operation will fail.
So we added CLK_SET_PARENT_GATE flag to avoid glitch.
And add imx8m_clk_hw_composite_bus_critical for bus critical clock usage

According to the latest RM (see Table 5-1. Clock Root Table),
both usdhc root clocks have the parent order as follows:
000 - 25M_REF_CLK
001 - SYSTEM_PLL1_DIV2
010 - SYSTEM_PLL1_CLK
011 - SYSTEM_PLL2_DIV2
100 - SYSTEM_PLL3_CLK
101 - SYSTEM_PLL1_DIV3
110 - AUDIO_PLL2_CLK
111 - SYSTEM_PLL1_DIV8
So the audio_pll2_out and sys3_pll_out have to be swapped.

If the GDSC is enabled out of boot but doesn't have the retain ff bit
set we will get confusing results where the registers that are powered
by the GDSC lose their contents on the first power off of the GDSC but
thereafter they retain their contents. This is because gdsc_init() fails
to make sure the RETAIN_FF bit is set when it probes the GDSC the first
time and thus powering off the GDSC causes the register contents to be
reset. We do set the RETAIN_FF bit the next time we power on the GDSC,
see gdsc_enable(), so that subsequent GDSC power off's don't lose
register contents state.
Forcibly set the bit at device probe time so that the kernel's assumed
view of the GDSC is consistent with the state of the hardware. This
fixes a problem where the audio PLL doesn't work on sc7180 when the
bootloader leaves the lpass_core_hm GDSC enabled at boot (e.g. to make a
noise) but critically doesn't set the RETAIN_FF bit.

The HSDK PLL driver is only useful when building for an ARC HSDK
platform.
As ARC selects OF, the dependency on OF can just be replaced by a
dependency on ARC_SOC_HSDK.
