[PATCH v7 0/6] Add clock controller support for SpacemiT K1

[PATCH v7 0/6] Add clock controller support for SpacemiT K1

[Haylen Chu]

The clock tree of SpacemiT K1 is managed by several independent
multifunction devices, some of them are

- Application Power Manage Unit, APMU
- Main Power Manage Unit, MPMU
- APB Bus Clock Unit, APBC
- APB Spare, APBS

These four devices provide hardware bits for three purposes: power
management, reset signals and clocks. Not every device is capable of all
the three functionalities,

- APMU, MPMU: power, reset, clock
- APBC: clock, reset
- APBS: clock (PLL clocks)

This series adds support for clock hardwares in these four regions,
which covers most peripherals except DDR and the realtime processor.

Tested on BananaPi-F3 board. With some out-of-tree drivers, I've
successfully brought up I2C, RTC, MMC and ethernet controllers.

It has been a very long time since I sent v1 of the series, thanks for
everyone making suggestions and keeping track. I'm looking forward for
furthermore reviews, or getting it finally merged.

[Haylen Chu]

Add definition for the PLL found on SpacemiT K1 SoC, which takes the
external 24MHz oscillator as input and generates clocks in various
frequencies for the system.

[PATCH v7 3/6] clk: spacemit: Add clock support for SpacemiT K1 SoC

[Haylen Chu]

The clock tree of K1 SoC contains three main types of clock hardware
(PLL/DDN/MIX) and has control registers split into several multifunction
devices: APBS (PLLs), MPMU, APBC and APMU.

All register operations are done through regmap to ensure atomiciy
between concurrent operations of clock driver and reset,
power-domain driver that will be introduced in the future.

[PATCH v7 4/6] clk: spacemit: k1: Add TWSI8 bus and function clocks

[Haylen Chu]

The control register for TWSI8 clocks, APBC_TWSI8_CLK_RST, contains mux
selection bits, reset assertion bit and enable bits for function and bus
clocks. It has a quirk that reading always results in zero.

As a workaround, let's hardcode the mux value as zero to select
pll1_d78_31p5 as parent and treat twsi8_clk as a gate, whose enable mask
is combined from the real bus and function clocks to avoid the
write-only register being shared between two clk_hws, in which case
updates of one clk_hw zero the other's bits.

With a 1:1 factor serving as placeholder for the bus clock, the I2C-8
controller could be brought up, which is essential for boards attaching
power-management chips to it.

I know Inochi wanted this to be "m", but you can see that
SOPHGO sets it to "y".  Meanwhile SIFIVE uses a default
value for its CLK_SIFIVE and CLK_SIFIVE_PRCI config options.

I'm not going to solve this, so I'll just say this looks good.

Re: [PATCH v7 0/6] Add clock controller support for SpacemiT K1

[Yixun Lan]

Hi Haylen Chu:
   I'm quite happy with this version, as all the issues are solved,
Thanks for working on this. I will give my RY and start to queue them.

Hi Stephen Boyd,
  My plan to send a PR for inclusion to the clk tree in the 6.16
merge window. But, let me know if there is still problem I overlooked.

The clock and pinctrl are exceptions for me, It is OK for me to set
"y" for these two device in defconfig. The thing I only asked for is 
a tristate entry in the kconfig, so we can go with a module if 
necessary.

If possible, split the patch into multiple one by the compatible
so others can review easily. Otherwise, it is LGTM.

You should send the code now. The merge window is when subsystem
maintainers like me send code to Linus, not when SoC maintainers send
code to subsystem maintainers. Typically folks wait until around -rc5 or
-rc6 to send it for the next merge window.

Sorry, I was not precise on this. the PR should target for v6.16 via clk tree

Thanks for the information, I was planning to send a PR to you (clk maintainer)
at v6.15-rc6 which should eventually merged into v6.16 ..
