[PATCH v2 0/3] mmc: renesas_sdhi: extend quirk selection to handle ES revisions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi,

Recent datasheet updates have made it clear that some quirks are not SoC
specific but SoC + ES version specific. Currently the quirks are
selected using compatibility values but whit this new information that
is not enough.

Patch 1/3 adds support to select quirks based on SoC + ES revision using 
soc_device_match() and converts the only existing quirk. Patch 2/3 
Removes the old method to select quirk based on compatibility string.  
While Patch 3/3 adds a new quirk from the BSP which blacklists some 
known problematic ES versions for HS400. HS400 is not yet enabled 
upstream so blacklisting these ES versions is not a regression of 
functionality.

Based on mmc/next and tested on H3 and M3-N.

Niklas Söderlund (3):
  mmc: renesas_sdhi: handle 4tap hs400 mode quirk based on SoC revision
  mmc: renesas_sdhi: align compatibility properties for H3 and M3-W
  mmc: renesas_sdhi: disable HS400 on H3 ES1.x and M3-W ES1.x
