The SM8150 list of clks is almost the same as the list for SDM845,

SM8150 list for now so we can reduce the amount of struct bloat in this
driver.

Some RCGs (the gfx_3d_src_clk in msm8998 for example) are basically just
some constant ratio from the input across the entire frequency range. It
would be great if we could specify the frequency table as a single entry
constant ratio instead of a long list, ie:
{ .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 },
{ }
So, lets support that.
We need to fix a corner case in qcom_find_freq() where if the freq table
is non-null, but has no frequencies, we end up returning an "entry" before
the table array, which is bad. Then, we need ignore the freq from the
table, and instead base everything on the requested freq.

When MSM8998 support was added, and analysis was done to determine what
clocks would be consumed. That analysis had a flaw, which caused the
pnoc to be skipped. The pnoc clock needs to be on to access the uart
for the console. The clock is on from boot, but has no consumer votes
in the RPM. When we attempt to boot the modem, it causes the RPM to
turn off pnoc, which kills our access to the console and causes CPU hangs.
We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in
an implicit vote for linux and prevent issues when booting modem.
Hopefully pnoc can be consumed by the interconnect framework in future
so that Linux can rely on explicit votes.

clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs

Some MMC cards fail to enumerate properly when inserted into an MMC slot
on sdm845 devices. This is because the clk ops for qcom clks round the
frequency up to the nearest rate instead of down to the nearest rate.
For example, the MMC driver requests a frequency of 52MHz from
clk_set_rate() but the qcom implementation for these clks rounds 52MHz
up to the next supported frequency of 100MHz. The MMC driver could be
modified to request clk rate ranges but for now we can fix this in the
clk driver by changing the rounding policy for this clk to be round down
instead of round up.

side. The two main highlights in the core framework are the addition of an bulk
clk_get API that handles optional clks and an extra debugfs file that tells the
developer about the current parent of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is mostly
because that SoC has started converting to the clk_hw style of clk
registration. The next big update is in the Amlogic meson clk driver that
gained some support for audio, cpu, and temperature clks while fixing some PLL
issues. Finally, the biggest thing that stands out is the conversion of a large
part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
less strings and more pointer comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks here and
there to clk data along with the normal addition of a handful of new drivers
and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"This round of clk driver and framework updates is heavy on the driver
update side. The two main highlights in the core framework are the
addition of an bulk clk_get API that handles optional clks and an
extra debugfs file that tells the developer about the current parent
of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is
mostly because that SoC has started converting to the clk_hw style of
clk registration. The next big update is in the Amlogic meson clk
driver that gained some support for audio, cpu, and temperature clks
while fixing some PLL issues. Finally, the biggest thing that stands
out is the conversion of a large part of the Allwinner sunxi-ng driver
to the new clk parent scheme that uses less strings and more pointer
comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks
here and there to clk data along with the normal addition of a handful
of new drivers and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks
- Add Amlogic g12a temperature sensors clocks
- Add Amlogic g12a and g12b cpu clocks
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
- Add CMM (Color Management Module) clocks on Renesas R-Car M3-W
- Add Clock Domain support on Renesas RZ/N1"
