Add support for Amlogic S4 PWM, including the driver and DTS.
Signed-off-by: Kelvin Zhang <kelvin.zhang@amlogic.com>
---
Changes in v6:
- Rename 'pwm_meson_s4_data' to 'pwm_s4_data'.
- Rename 'meson_pwm_init_channels_meson_s4' to 'meson_pwm_init_channels_s4'.
- Adjust the order of the device nodes according to their unit addresses.
- Some minor improvements.
- Link to v5: https://lore.kernel.org/r/20240521-s4-pwm-v5-0-0c91f5fa32cd@amlogic.com
Changes in v5:
- Add devm_add_action_or_reset for free clk when unloading.
- Replace the underscores of node name with dashes.
- Link to v4: https://lore.kernel.org/r/20240424-s4-pwm-v4-0-ee22effd40d0@amlogic.com
