[PATCH V11 0/4] Add S4 SoC PLLs and Peripheral clock

[PATCH V11 0/4] Add S4 SoC PLLs and Peripheral clock

[Yu Tu]

1. Add S4 SoC PLLs and Peripheral clock controller dt-bindings.
2. Add PLLs and Peripheral clock controller driver for S4 SOC.

Yu Tu (4):
  dt-bindings: clock: document Amlogic S4 SoC PLL clock controller
  dt-bindings: clock: document Amlogic S4 SoC peripherals clock
    controller
  clk: meson: S4: add support for Amlogic S4 SoC PLL clock driver
  clk: meson: S4: add support for Amlogic S4 SoC peripheral clock
    controller

V10 -> V11:
1. Change patch 0001/0002 dt-bindings tag. Suggested by Krzysztof.
2. Change patch 0002 dt-bindings added minItems. Suggested by Jerome.
3. Change patch 0004 added clock ".flags = 0" and comment. Suggested by Jerome.

V9 -> V10:
1. Change the relevant S4 CLK patch based on Neil's recently modified
patch.
2. Change patch 0003/0004 clocks comment, format and clock flags suggested
by Jerome.

V8 -> V9: Add patch 0001/0002 dt-bindings tag. Suggested by Krzysztof.
V7 -> V8:
1. Change patch 0001/0002 dt-bindings title description, remove "meson".
Suggested by Dmitry, Neil.
2. Change patch 0003/0004 clocks comment, format and clock flags suggested by
Dmitry, Neil, Jerome.

V6 -> V7: Change send patch series as well change format and clock flags
suggested by Jerome. Change dt-bindings suggested by Krzysztof.
V5 -> V6: Change send patch series, as well change format and clock flags.
V4 -> V5: change format and clock flags and adjust the patch series
as suggested by Jerome.
V3 -> V4: change format and clock flags.
V2 -> V3: Use two clock controller.
V1 -> V2: Change format as discussed in the email.
