FAQ_MA35D1_SSPCC Clock and CLK_SYSCLK1 Operating

[ytliu6]

For example, you can read/write WDT register at Linux stage but not CLK_SYSCLK1(0x40460208) and SSPCC.

SSPCC belong to TZS register, so it only can be modified at TF-A stage.

Linux kernel doesn’t allow users modify CLK_SYSCLK1, so you need to modify clock source code and compile it again.
