I also need to test Samuel's patch on real hardware. Probably, I could
share my test result next week because I'm in a business trip. Will
share my test result as soon as I back to office. Also, I'm currently
asking Aspeed engineers to check the parent clock of the LCLK to fill
out the parent clock info in clk-aspeed.c. If it is available, we would
not need to use CLK_IS_CRITICAL flag, I'm guessing. Will update this
thread as soon as possible.
