In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx8mp-blk-ctrl: imx8mp_blk: Add fdcc clock to hdmimix domain

According to i.MX8MP RM and HDMI ADD, the fdcc clock is part of
hdmi rx verification IP that should not enable for HDMI TX.
But actually if the clock is disabled before HDMI/LCDIF probe,
LCDIF will not get pixel clock from HDMI PHY and print the error
logs:

[CRTC:39:crtc-2] vblank wait timed out
WARNING: CPU: 2 PID: 9 at drivers/gpu/drm/drm_atomic_helper.
