Changes in v8:
- Return dev_err_probe() in meson_pwm_init_channels_s4().
- Check the result of devm_add_action_or_reset().
- Link to v7: https://lore.kernel.org/r/20240605-s4-pwm-v7-0-e822b271d7b0@amlogic.com

Changes in v7:
- Put devm_add_action_or_reset() into the for loop.
- Remove the error handling of meson_pwm_init_channels_s4().
- Remove the repeated device node 'pwm-a-pins'.
- Some minor fixes and improvements.
- Link to v6: https://lore.kernel.org/r/20240529-s4-pwm-v6-0-270f63049f20@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.
