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.
