From: Jacky Huang <ychuang3@nuvoton.com>

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.

What is 'dummy'? Is that in the binding? Note, don't put both .fw_name
and .name in the binding. For new drivers, prefer to use .index or .hw
and never use .name to describe parents.

Is this header included in one C file? If so, remove the header file and
put the contents in the C file.

I will remove "dummy" and use .index or .hw instead.
