This series upports two BSP improvements in a refactored way. BSP patch
de9461ece1fa ("mmc: renesas_sdhi: scc_ctl is always set in after R-Car
Gen3") made sure we have a pointer to always reset SCC. I refactored it
to include Gen2 as well, so we can optimize the following code a bit.
This is patch 1. BSP patch 15d7abbfc3f0 ("mmc: renesas_sdhi: reset
calibration register") added a new quirk for devices which always should
disable HS400 adjustment. This was only applicable for SoCs which either
had bad_taps or needed a calibration table. So, I simply used this logic
directly instead of a quirk. This is patch 2.
Two cleanups come afterwards. To increase readability, I finally did
something I wanted to do for some time now. Having a helper to check for
SDHI quirks. This is patch 3. And while working on this, I discovered a
new macro from the MMC core which we can make use of. This is patch 4.
The series has been tested on a Salvator-XS (R-Car M3-N) and a Lager
(R-Car H2) board. The patches are based on mmc/next as of today as they
depend on d901e2ba566 ("mmc: renesas_sdhi: take DMA end interrupts into
account"). A branch can be found here:
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/sdhi/for-6.2
Let me know what you think!
Happy hacking,
Wolfram
