Subject: [PATCH v3 0/2] Fix incorrect resolution detected

This series fixes incorrect resolution detected.
We found this problem happened occasionally in the switch between bios
and bootloader.

Changes in v3:
 - In v2, we tried to increase the min-required-count of stable signal
   to avoid incorrect transient state in timing detection. But it is
   not working for all conditions.
   Thus, we go another way in v3. Use regs, which can represent the
   signal status, to decide if we needs to do detection again.
 
Changes in v2:
 - Separate the patch into two patches

Jammy Huang (2):
  media: aspeed: Add macro for the fields of the mode-detect registers
  video: aspeed: Fix unstable timing detection
