From: Jacky Huang <[email protected]>
This patchset adds initial support for the Nuvoton ma35d1 SoC, including
initial device tree, clock driver, reset driver, and serial driver.
This patchset cover letter is based from the initial support for Nuvoton
ma35d1 to keep tracking the version history.
This patchset had been applied to Linux kernel 6.3.0-12728-g348551ddaf31-dirty
and tested on the Nuvoton ma35d1 SOM evaluation board.
(ma35d1 information: https://www.nuvoton.com/products/microprocessors/arm-cortex-a35-mpus/)

2.34.1
From: Jacky Huang <[email protected]>
The clock controller generates clocks for the whole chip, including
system clocks and all peripheral clocks. This driver support ma35d1
clock gating, divider, and individual PLL configuration.
There are 6 PLLs in ma35d1 SoC:
- CA-PLL for the two Cortex-A35 CPU clock
- SYS-PLL for system bus, which comes from the companion MCU
and cannot be programmed by clock controller.
- DDR-PLL for DDR
- EPLL for GMAC and GFX, Display, and VDEC IPs.
- VPLL for video output pixel clock
- APLL for SDHC, I2S audio, and other IPs.
CA-PLL has only one operation mode.
DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3
operation modes: integer mode, fraction mode, and spread specturm mode.
