This looks good, but I'm seeing some checkpatch style warnings, with
those fixed feel free to add my r-b.
CHECK: Alignment should match open parenthesis
#32: FILE: drivers/gpu/drm/bridge/adv7511/adv7511_drv.c:791:
+ regmap_update_bits(adv7511->regmap, 0xfb,
+ 0x6, low_refresh_rate << 1);
CHECK: Alignment should match open parenthesis
#35: FILE: drivers/gpu/drm/bridge/adv7511/adv7511_drv.c:794:
+ regmap_update_bits(adv7511->regmap, 0x4a,
+ 0xc, low_refresh_rate << 2);
total: 0 errors, 0 warnings, 2 checks, 15 lines checked
NOTE: For some of the reported defects, checkpatch may be able to
mechanically convert to the typical style using --fix or --fix-inplace.
Commit 1955dfe734e4 ("drm: adv7511: Fix low refresh rate register for
ADV7533/5") has style problems, please review.
NOTE: If any of the errors are false positives, please report
