Subject: [PATCH v2 0/2] mmc: mtk-sd: Limit second register range to SoCs requiring it

Changes since v1:
- Added MT7988 compatible string to list that needs second register
  range
- Dropped comment about uncertainty of MT6779 from commit message
- Picked up Angelo's Reviewed-by

Currently the usage of a second register range for MediaTek's MMC
controller is seen only on a few platforms. However the driver tries
to grab the register base regardless, and then ignores any errors.
This makes all the other platforms that don't need it produce confusing
error messages.

Instead, make the driver only grab the register range for platforms that
actually require it, and correctly handle the error. Also fix up the
binding so that validation of the "reg" property is as strict as
possible.

Please take a look.


Thanks
ChenYu
