Subject: [PATCH v3 0/4] mmc: sdhci-of-dwcmshc: enhance framework

From: Chen Wang <unicorn_wang@...look.com>

When I tried to add a new soc to sdhci-of-dwcmshc, I found that the
existing driver code could be optimized to facilitate expansion for
the new soc. You can see another patch [sg2042-dwcmshc], which I am
working on to add SG2042 to sdhci-of-dwcmshc.

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.

Changes in v3:

  The patch series is based on latest 'next' branch of [mmc-git].

  Improved the dirvier code as per comments from Adrian Hunter.
  Define new structure for dwcmshc platform data/ops. In addition, I organized
  the code and classified the helper functions.

  Since the file changes were relatively large (though the functional logic did
  not change much), I split the original patch into four for the convenience of
  review.

Changes in v2:

  Rebased on latest 'next' branch of [mmc-git]. You can simply review or test the
  patches at the link [2].

Changes in v1:

  The patch series is based on v6.9-rc1. You can simply review or test the
  patches at the link [1].
