Linus Torvalds 75d6e7d9ce Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by
 the respective maintainers.
 
 New Drivers:
  - Support video, gpu, display clks on qcom sc7280 SoCs
  - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
  - Multimedia clks (MMCC) on qcom MSM8994/MSM8992
  - RPMh clks on qcom SM6350 SoCs
  - Support for Mediatek MT8192 SoCs
  - Add display (DU and DSI) clocks on Renesas R-Car V3U
  - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
    resets on Renesas RZ/G2L
 
 Updates:
  - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
  - Add power of two flag to fractional divider clk type
  - Migrate some clk drivers to clk_divider_ops.determine_rate
  - Migrate to clk_parent_data in gcc-sdm660
  - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
  - Switch from .round_rate to .determine_rate in clk-divider-gate
  - Fix clock tree update for TF-A controlled clocks for all i.MX8M
  - Add missing M7 core clock for i.MX8MN
  - YAML conversion of rk3399 clock controller binding
  - Removal of GRF dependency for the rk3328/rk3036 pll types
  - Drop CLK_IS_CRITICAL flag from Tegra fuse clk
  - Make CLK_R9A06G032 Kconfig symbol invisible

Commit 5658e8cf1a ("clk: qcom: add video clock controller driver for
SM8150") and commit 0e94711a1f ("clk: qcom: add video clock controller
driver for SM8250") add config SM_VIDEOCC_8150 and config SM_VIDEOCC_8250,
which select the non-existing configs SDM_GCC_8150 and SDM_GCC_8250,
respectively.

Hence, ./scripts/checkkconfigsymbols.py warns:

SDM_GCC_8150
Referencing files: drivers/clk/qcom/Kconfig

SDM_GCC_8250
Referencing files: drivers/clk/qcom/Kconfig

It is probably just a typo (or naming confusion of using SM_GCC_xxx and
SDM_GCC_xxx for various Qualcomm clock drivers) in the config definitions
for config SM_VIDEOCC_8150 and SM_VIDEOCC_8250, and intends to select the
existing SM_GCC_8150 and SM_GCC_8250, respectively.

Adjust the selects to the existing configs.

Bjorn Andersson da09577ab5 clk: qcom: gcc-sdm660: Replace usage of parent_names
Using parent_data and parent_hws, instead of parent_names, does protect
against some cases of incompletely defined clock trees. While it turns
out that the bug being chased this time was totally unrelated, this
patch converts the SDM660 GCC driver to avoid such issues.

The "xo" fixed_factor clock is unused within the gcc driver, but
referenced from the DSI PHY. So it's left in place until the DSI driver
is updated.

MSM8939 has 3 a53pll clocks with different frequency table for Cluster0,
Cluster1 and CCI.  It adds function qcom_a53pll_get_freq_tbl() to create
pll_freq_tbl from OPP, so that those a53pll frequencies can be defined
in DT with operating-points-v2 bindings rather than being coded in the
driver.  In this case, one compatible rather than three would be needed
for these 3 a53pll clocks.

Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets
three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache
Coherent Interconnect).  That said, a53pll/mux clock needs to be named
uniquely.  Append @unit-address of device node to the clock name, so
that a53pll/mux will be named like below on MSM8939.

  a53pll@b016000
  a53pll@b116000

The clock source for MSM8916 cpu cores is like below.

                        |\
         a53pll --------| \ a53mux     +------+
                        | |------------| cpus |
     gpll0_vote --------| /            +------+
                        |/

So a53mux rather than a53pll is actually the parent clock of cpu cores.
It makes more sense to flag a53mux as critical instead, so that when
either a53pll or gpll0_vote is used by cpu cores, the clock will be kept
enabled while the other can be disabled.

Bjorn Andersson 9711759a87 clk: qcom: gdsc: Ensure regulator init state matches GDSC state
As GDSCs are registered and found to be already enabled gdsc_init()
ensures that 1) the kernel state matches the hardware state, and 2)
votable GDSCs are properly enabled from this master as well.

But as the (optional) supply regulator is enabled deep into
gdsc_toggle_logic(), which is only executed for votable GDSCs, the
kernel's state of the regulator might not match the hardware. The
regulator might be automatically turned off if no other users are
present or the next call to gdsc_disable() would cause an unbalanced
regulator_disable().

Given that the votable case deals with an already enabled GDSC, most of
gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just
clearing the SW_COLLAPSE_MASK and enabling hardware control to simply
call regulator_enable() in both cases.

The enablement of hardware control seems to be an independent property
from the GDSC being enabled, so this is moved outside that conditional
segment.

Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to
happen regardless of the initial state this is grouped together with the
other sc->pd updates at the end of the function.

Bjorn Andersson 17fef808ed clk: qcom: dispcc-sm8250: Add additional parent clocks for DP
The clock controller has two additional clock source pairs, in order to
support more than a single DisplayPort PHY. List these, so it's possible
to describe them all.

Also drop the unnecessary freq_tbl for the link clock sources, to allow
these parents to be used.

Shawn Guo 4ee107c514 clk: qcom: smd-rpm: Fix MSM8936 RPM_SMD_PCNOC_A_CLK
Commit a0384ecfe2 ("clk: qcom: smd-rpm: De-duplicate identical
entries") introduces the following regression on MSM8936/MSM8939, as
RPM_SMD_PCNOC_A_CLK gets pointed to pcnoc_clk by mistake.  Fix it by
correcting the clock to pcnoc_a_clk.

Chen Hui d0a859edda clk: qcom: apss-ipq-pll: Add missing MODULE_DEVICE_TABLE
CONFIG_IPQ_APSS_PLL is tristate option and therefore this driver can
be compiled as a module. This patch adds missing MODULE_DEVICE_TABLE
definition which generates correct modalias for automatic loading of
this driver when it is built as an external module.
