Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

As in most cases, using 'imply' is wrong here and does not prevent
build failures since that code may not be visible to a built-in
clk driver:
axg-audio.c:(.text+0x15c): undefined reference to `devm_meson_rst_aux_register'
Replace the incorrt 'imply' with the necessary 'depends on'.

When dealing with certain PLLs, it is necessary to avoid modifying them
if they have already been initialized by lower levels. For instance, in
the A1 SoC Family, the sys_pll is enabled as the parent for the cpuclk,
and it cannot be disabled during the initialization sequence. Therefore,
initialization phase must be skipped.

In order to setup the DSI clock, let's make the unused VCLK2 clock path
configuration via CCF.
The nocache option is removed from following clocks:
- vclk2_sel
- vclk2_input
- vclk2_div
- vclk2
- vclk_div1
- vclk2_div2_en
- vclk2_div4_en
- vclk2_div6_en
- vclk2_div12_en
- vclk2_div2
- vclk2_div4
- vclk2_div6
- vclk2_div12
- cts_encl_sel
vclk2 and vclk2_div uses the newly introduced vclk regmap driver
to handle the enable and reset bits.
In order to set a rate on cts_encl via the vclk2 clock path,
the NO_REPARENT flag is set on cts_encl_sel & vclk2_sel in order
to keep CCF from selection a parent.
The parents of cts_encl_sel & vclk2_sel are expected to be defined
in DT or manually set by the display driver at some point.
The following clock scheme is to be used for DSI:
xtal
\_ gp0_pll_dco
\_ gp0_pll
|- vclk2_sel
| \_ vclk2_input
| \_ vclk2_div
| \_ vclk2
| \_ vclk2_div1
| \_ cts_encl_sel
| \_ cts_encl -> to VPU LCD Encoder
|- mipi_dsi_pxclk_sel
\_ mipi_dsi_pxclk_div
\_ mipi_dsi_pxclk -> to DSI controller
The mipi_dsi_pxclk_div is set as bypass with a single /1 entry in div_table
in order to use the same GP0 for mipi_dsi_pxclk and vclk2_input.
The SET_RATE_PARENT is only set on the mipi_dsi_pxclk_sel clock so the
DSI bitclock is the reference base clock to calculate the vclk2_div value
when pixel clock is set on the cts_encl endpoint.

The VCLK and VCLK_DIV clocks have supplementary bits.
The VCLK gate has a "SOFT RESET" bit to toggle after the whole
VCLK sub-tree rate has been set, this is implemented in
the gate enable callback.
The VCLK_DIV clocks as enable and reset bits used to disable
and reset the divider, associated with CLK_SET_RATE_GATE it ensures
the rate is set while the divider is disabled and in reset mode.
The VCLK_DIV enable bit isn't implemented as a gate since it's part
of the divider logic and vendor does this exact sequence to ensure
the divider is correctly set.

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
Updates:
- Add __counted_by to struct clk_hw_onecell_data and struct
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()
- Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
consider alternative parent rates when determining clock rates
- Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
- Support finding closest (as opposed to closest but not higher)
clock rate for NM, NKM, mux and div type clocks, as use it for
Allwinner A64 pll-video0

Allwinner NKM clocks
- Clean up Qualcomm SMD RPM driver, with interconnect bus clocks

- Add network related resets on Qualcomm IPQ4019
- Add a couple missing USB related clocks to Qualcomm IPQ9574
- Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock
controller
- In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs,
and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are
corrected
- Add missing GDSCs to and correct GDSCs for the SC8280XP global
clock controller driver
- Support retention for the Qualcomm SC8280XP display clock
controller GDSCs.
- Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE
to fix issues with missing parent clocks across sc7180, sm7150,
sm6350 and sm8250, while sm8450 is corrected to use floor ops

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.
