Subject: [PATCH RFC v3 0/7] clk: thead: Add support for TH1520 AP_SUBSYS clock controller

This series adds support for the AP sub-system clock controller in the
T-Head TH1520 [1]. Yangtao Li originally submitted this series in May
2023 [2]. Jisheng made additional improvements and then passed on the
work in progress to me.

Changes in RFC v3:
- Drop redundant new line and unused clk label from the dts example in
the DT binding which I failed to fix in v2.
- Add patch [3] from Thomas Bonnefille that fixes dts node ordering in
th1520.dtsi. Conor has already merged it into riscv-dt-for-next so
the dts patches in this series are based on top of that.
- Remove fixed uart clock and converted uart DT nodes to use clocks
from the clock controller.
- Remove fixed apb clock and converted the dma controller and timer DT
nodes to use a clock from the clock controller.
- Made ccu_disable_helper() and ccu_enable_helper() to static functions
- Follow the advice from Stephen Boyd in Yangtao's original series to
not use strings for clk tree topology. Created clk_parent_data arrays
to be used with CLK_HW_INIT_PARENTS_DATA instead of parent strings.
- Rebase on top of v6.9-rc7

Changes in RFC v2 [4]:
- squash the header file patch into the DT schema patch
- describe the changes I made to original series in the cover letter
instead of the individual patches
- fix my typo in my email address

Changes in RFC v1 [5] from the original series:
- corrected the npu_clk enable bit
- deduplicated CLK_NPU and CLK_NPU_AXI number in header
- fixed c910_i0_clk reg typo
- fixed checkpatch and dt_binding_check warnings
- rebased on v6.9-rc5
- revised commit descriptions

TODO:
This is still marked as an RFC because I still need to make the
improvements that Emil suggested in v1:
- Input predivider is not handled correctly in ccu_mdiv_recalc_rate().
The PLL multiplies the input frequency and outputs "Foutvco". This is
followed by a post divider to produce "Foutpostdiv". However, some
clocks derive directly from the "Foutvco". These should be modelled
as two differnt clocks.
- Use devm_clk_hw_register_gate() for the gates
- Use devm_clk_hw_register_mux() for the muxes

I'll post a v1 patch once I've addressed the above issues.

Thank you,
Drew

Subject: [PATCH RFC v3 6/7] riscv: dts: thead: change TH1520 mmc nodes to use clock controller

Change the clock property in the TH1520 mmc controller nodes to a clock
provided by AP_SYS clock controller.

Remove sdhci fixed clock reference from BeagleV Ahead and LPI4a dts.

Subject: [PATCH RFC v3 7/7] riscv: dts: thead: update TH1520 dma and timer nodes to use clock controller

Change the dma-controller and timer nodes to use the APB clock provided
by the AP_SUBSYS clock controller.

Remove apb_clk reference from BeagleV Ahead and LPI4a dts.

I recommend dropping clock-names so that you don't rely on anything
besides the cell index when describing clk_parent_data.

If you can't drop it at least make it optional.
