This is a patch series for PWM driver for Suplus SP7021 SoC.

Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART. I2C, SPI, SDIO, eMMC, USB, SD card and
etc.) into a single chip. It is designed for industrial control.

I just noticed as I was trying to do test builds that ARCH_SUNPLUS
doesn't exist yet. Are there any plans to add those in the near future?

I can always use COMPILE_TEST to do test build, but I like to also do
proper builds because they sometimes flag things that COMPILE_TEST
misses (like this one).

Yes, my colleague is working on it right now.
But he submitted too many items at a time. (clock/reset/interrupt,
defconfig/, arch/arm...)
Current patch v13, still ongoing.
