This patchset is composed of two parts:
- one is the improvement of the sdhci-of-dwcmshc framework,
- the other is the support for sg2042 based on the improvement of the
framework.
The reason for merging the two parts into one patchset is mainly to
facilitate review, especially to facilitate viewing why we need to
improve the framework and what benefits it will bring to us.
When I tried to add a new soc(SG2042) to sdhci-of-dwcmshc, I found
that the existing driver code could be optimized to facilitate expansion
for the new soc. Patch 1 ~ Patch 5 is for this.
Patch 6 ~ 7 are adding support for the mmc controller for Sophgo SG2042.
Adding corresponding new compatible strings, and implement
custom callbacks for SG2042 based on new framework.
Patch 8 is the change for DTS.
By the way, although I believe this patch only optimizes the framework
of the code and does not change the specific logic, simple verification
is certainly better. Since I don't have rk35xx/th1520 related hardware,
it would be greatly appreciated if someone could help verify it.
Note, the DTS change has dependency on clock changes for SG2042, which
has not been merged in master/upstream, so if you want to test this
new sdhci-of-dwcmshc driver for other hardware except SG2042, don't
pick patch 8.
I have tested this on the LicheePi 4a and found no issues.
