Wanted to send out v2 of this patch set improving the EDID probing on the adv7511 used on HiKey.
The first three patches are fixups that are hopefully straight forward, integrating feedback I got from Laurant.
One of the previous patches that Laurant had concerns about, I broke into two patches, which are the last two in this series. The core issue seems to be something going wrong with the regmap cache state for the ADV7511_REG_EDID_I2C_ADDR (0x43) register which results in i2c_transfer errors if we don't do the regcache_sync/_mark_dirty() calls. I suspect there might be a better solution there, so suggestions will be very welcome.
Thoughts and feedback would be appreciated!
thanks -john
