Pull clk subsystem updates from Stephen Boyd:
"This pull request is full of clk driver changes. In fact, there aren't
any changes to the clk framework this time around. That's probably
because everyone was on vacation (yours truly included). We did lose a
couple clk drivers this time around because nobody was using those
devices. That skews the diffstat a bit, but either way, nothing looks
out of the ordinary here. The usual suspects are chugging along adding
support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a
handful of patches that move the NR_CLKS define from the DT binding
header to the driver. There's even patches that migrate drivers to use
clk_parent_data and clk_hw to describe clk tree topology. It seems
that the spring (summer?) cleaning bug got some folks, or the
semiconductor shortage finally hit the software side.
New Drivers:
- StarFive JH7110 SoC clock drivers
- Qualcomm IPQ5018 Global Clock Controller driver
- Versa3 clk generator to support 48KHz playback/record with audio
codec on RZ/G2L SMARC EVK

- Remove non-OF mmp clk drivers
- Remove OXNAS clk driver

spmi_pmic_div_clk_cc
- Move defines for numbers of clks (NR_CLKS) from DT headers to
drivers

- Add PLL rates for Rockchip rk3568
- Add the display clock tree for Rockchip rv1126
- Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
RZ/G2 SoCs
- Convert sun9i-mmc clock to use
devm_platform_get_and_ioremap_resource()
- Fix function name in a comment in ccu_mmc_timing.c
- Parameter name correction for ccu_nkm_round_rate()

Due to a policy change in clock ID bindings handling, expose
all the "private" clock IDs to the public clock dt-bindings
to move out of the previous maintenance scheme.
This refers to a discussion at [1] & [2] with Krzysztof about
the issue with the current maintenance.
It was decided to move every axg-audio-clkc ID to the public clock
dt-bindings headers to be merged in a single tree so we
can safely add new clocks without having merge issues.

Let's introduce a new module called meson-clkc-utils that
will contain shared utility functions for all Amlogic clock
controller drivers.
The first utility function is a replacement of of_clk_hw_onecell_get
in order to get rid of the NR_CLKS define in all Amlogic clock
drivers.
The goal is to move all duplicate probe and init code in this module.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The function meson_clk_pll_enable() can be invoked under the enable_lock

Modern meson PLL IPs are a little bit different from early known PLLs.
The main difference is located in the init/enable/disable sequences; the
rate logic is the same.
In A1 PLL, the PLL enable sequence is different, so add new optional pll
reg bits and use the new power-on sequence to enable the PLL:
1. enable the pll, delay for 10us
2. enable the pll self-adaption current module, delay for 40us
3. enable the lock detect module

There are reports that 48kHz audio does not work on the WeTek Play 2
(which uses a GXBB SoC), while 44.1kHz audio works fine on the same
board. There are also reports of 48kHz audio working fine on GXL and
GXM SoCs, which are using an (almost) identical AIU (audio controller).
Experimenting has shown that MPLL0 is causing this problem. In the .dts
we have by default:
assigned-clocks = <&clkc CLKID_MPLL0>,
<&clkc CLKID_MPLL1>,
<&clkc CLKID_MPLL2>;
assigned-clock-rates = <294912000>,
<270950400>,
<393216000>;
The MPLL0 rate is divisible by 48kHz without remainder and the MPLL1
rate is divisible by 44.1kHz without remainder. Swapping these two clock
rates "fixes" 48kHz audio but breaks 44.1kHz audio.
Everything looks normal when looking at the info provided by the common
clock framework while playing 48kHz audio (via I2S with mclk-fs = 256):
mpll_prediv 1 1 0 2000000000
mpll0_div 1 1 0 294909641
mpll0 1 1 0 294909641
cts_amclk_sel 1 1 0 294909641
cts_amclk_div 1 1 0 12287902
cts_amclk 1 1 0 12287902
meson-clk-msr however shows that the actual MPLL0 clock is off by more
than 38MHz:
mp0_out 333322917 +/-10416Hz
The rate seen by meson-clk-msr is very close to what we would get when
SDM (the fractional part) was ignored:
(2000000000Hz * 16384) / ((16384 * 6) = 333.33MHz
If SDM was considered the we should get close to:
(2000000000Hz * 16384) / ((16384 * 6) + 12808) = 294.9MHz
Further experimenting shows that HHI_MPLL_CNTL7[15] does not have any
effect on the rate of MPLL0 as seen my meson-clk-msr (regardless of
whether that bit is zero or one the rate is always the same according to
meson-clk-msr). Using HHI_MPLL_CNTL[25] on the other hand as SDM_EN
results in SDM being considered for the rate output by the hardware. The
rate - as seen by meson-clk-msr - matches with what we expect when
SDM_EN is enabled (fractional part is being considered, resulting in a
294.9MHz output) or disable (fractional part being ignored, resulting in
a 333.33MHz output).

Add the reg_sequence to initialize the HDMI PLL with the settings for
a video mode that doesn't require PLL internal clock doubling. These
settings are taken from the 3.10 vendor kernel's driver for the 2970MHz
PLL setting used for the 1080P video mode. This puts the PLL into a
defined state and the Linux kernel can take over.
While not all bits for this PLL are implemented using these "defaults"
and then applying M, N and FRAC seems to work fine.

The 3.10 vendor kernel uses only specific HDMI PLL M/N parameter
combinations. The PLL won't lock for values smaller than 50 if the
internal doubling (which is yet unknown how to use it) is disabled.
However, when this doubling is enabled then the values smaller than 50
will lock just fine. The only restriction for values greater than 50 is
that the resulting frequency must not exceed the 3.0GHz limit.
These values are taken from the endlessm 3.10 kernel which includes
additional M/N combinations for some VESA and 75Hz display modes.

HHI_VID_DIVIDER_CNTL[11] must be enabled for the video clock tree to
work. This bit is described as "LVDS_CLK_EN". It is not 100% clear where
this bit has to be placed in the hierarchy. But since the "LVDS_OUT" of
the HDMI PLL uses it's own set of registers it's more likely that this
"LVDS_CLK_EN" bit actually enables the input of the "hdmi_pll_lvds_out"
clock to the "vid_pll_in_sel" tree.
Add a gate definition for this bit (which will not be exported) so that
the kernel can manage all required bits to enable and disable the video
clocks.

This increases the maxmium supported frequency on 32-bit systems from
2^31 (signed long as used by clk_ops.round_rate, maximum value:
approx. 2.14GHz) to 2^32 (unsigned long as used by
clk_ops.determine_rate, maximum value: approx. 4.29GHz).
On Meson8/8b/8m2 the HDMI PLL and it's OD (post-dividers) are
capable of running at up to 2.97GHz. So switch the divider
implementation in clk-regmap to clk_ops.determine_rate to support these
higher frequencies on 32-bit systems.
