Subject: [PATCH 0/5] Add support for Allwinner H616 PWM
Date: Fri, 31 May 2024 23:11:32 +0900

Add support for the Allwinner H616 PWM, building on top of Aleksandr's
Allwinner D1 PWM driver v9.

Additionally, the 4th and 5th patches implement the proposed method
for delegating the clock source and DIV_M selection to the Device Tree.
While it works well without these patches with the original behavior,
applying them enables fine-grained control of PWM resolution and
prevents non-deterministic behavior dependent on the enabling order.

I have only been able to test on H700 (H616 variant) using an
oscilloscope. I would greatly appreciate it if someone could test
this patch series on the D1 or other models.

Regards,
kikuchan.
