If anyone has any objections, please let me know. ------------------ From: Yixun Lan [ Upstream commit eb525edd48907795c0d4e498ff57ad168070b289 ] HDMA clock is responsible for the internal TCM access path of X100 RISC-V core, so set the clock flag as critical to prevent it from being shut off, otherwise the Linux system will hang, for example in the case of a vector instruction access generates a page fault.
