LP8556: Backlight brightness is not stable for lp8556

Part Number: LP8556

Hi everyone

   I am using LP8556,Set A1h to 0x9D both uefi and kernel,but during the boot process, the backlight is relatively bright in the UEFI stage and darkens in the Kernel stage.

  Can you give me some advice?

Best Regards,
