[PATCH RESEND v3 0/3] clk: en7523: reset-controller support for EN7523 SoC

[Mikhail Kshevetskiy]

No any activity for a long time, so resend

These patches:
 * adds reset-controller support for EN7523 SoC
 * updates dt-bindings
 * updates en7523 dtsi

Reset-controller support will allow us more easily reusing of en7581 drivers
for en7523.

Changes v2:
 * keep '#reset-cells' property optional
 * put dtsi changes to a separate commit
 * add missed dtsi include

Changes v3:
 * keep en7581 prefix for common en7523/en7581 variables and functions

[PATCH RESEND v3 2/3] clk: en7523: Add reset-controller support for EN7523 SoC

[Mikhail Kshevetskiy]

Introduce reset API support to EN7523 clock driver. EN7523 uses the
same reset logic as EN7581, so just reuse existing code.

I wonder if this wouldn't be better moved out of hw_init(), with
rst_map and the corresponding ARRAY_SIZE() stored in struct
en_clk_soc_data. Registering a reset controller is not hardware
initialization, after all. But that's not an issue with this patch.

Hello Stephen,

I can't find this and other my commit in the clk-next. Are changes was
dropped?
If it was dropped, could you tell me a reason?

[PATCH RESEND v3 0/3] clk: en7523: reset-controller support for EN7523 SoC

[Mikhail Kshevetskiy]

No any activity for 3 weeks, so resend.

These patches:
 * adds reset-controller support for EN7523 SoC
 * updates dt-bindings
 * updates en7523 dtsi

Reset-controller support will allow us more easily reusing of en7581 drivers
for en7523.

Changes v2:
 * keep '#reset-cells' property optional
 * put dtsi changes to a separate commit
 * add missed dtsi include

Changes v3:
 * keep en7581 prefix for common en7523/en7581 variables and functions

  clk: en7523: Add reset-controller support for EN7523 SoC
  ARM: dts: airoha: update EN7523 dtsi to support resets
