[PATCH 0/4] mmc: tmio/SDHI fixup patches

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

 



Hi Chris

Now, our new board would like to use sh_mobile_sdhi driver,
then, it is expecting sh_mobile_sdhi use regulator.
But, this regulator is based on GPIO driver,
and GPIO driver probe timing is after sh_mobile_sdhi.
So, sh_mobile_sdhi (= tmio_mmc_pio) use default ocr_avail,
and it doesn't work for us.
#1 patch returns -EPROBE_DEFER in such case.
it changes tmio_mmc_host_probe() behavior, but
in my check, tmio_mmc_pio driver user is sh_mobile_sdhi/tmio-mmc only,
and, current user has no conflict by this patch.

sh_mobile_sdhi/tmio-mmc is very similar, but, have some difference.
#2 - #4 cares such case.

These were part of "SDHI support for r8a7790" patch set,
but was separated

Kuninori Morimoto (4):
      mmc: tmio: use -EPROBE_DEFER if driver can't find regulator
      mmc: tmio: bus_shift become tmio_mmc_data member
      mmc: tmio: add new TMIO_MMC_HAVE_HIGH_REG flags
      mmc: SDHI: add SoC specific workaround via HW version
