If only set MMC_CAP_8_BIT_DATA, not hook platform_8bit_width, I will get
the fllowing message.
The reason is ios->bus_width != MMC_BUS_WIDTH_8 and host->version<
SDHCI_SPEC_300 in drivers/mmc/host/sdhci.c, sdhci_set_ios().
I see. What I checked yesterday is not MeeGo kernel code and caused some
mis-understanding on this.
Now, I think this patch is OK but just want to confirm that did you have tested
it on MRST Langwell B0 and Langwell C0 platform?
I recalled that seems Langwell B0 does not support 8bit bus width. So, maybe it
needs to check Silicon version first before set the MMC_CAP_8_BIT_DATA cap bit,
right?
langwell B0 is not a stepping that goes into products so really don't
bother.
