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.c:1634
drm_atomic_helper_wait_for_vblanks.part.0+0x23c/0x260 Add fdcc clock to
LCDIF and HDMI TX power domains to fix the issue.
