[PATCH v2 0/2] mmc: sdhci: Add sdma_buffer_boundary_arg to sdhci_host

[srinivas . kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

This patchset adds fix to support sdhci controller which have issues
when sdma boundary buffer bits are programmed in Block Size Register (0x04)
when using ADMA.

First patch adds member to struct sdhci_host to allow drivers to
specify sdma_buffer_boundary value that it can support and second
one sets sdma_buffer_boundary_arg to zero in msm sdhci driver.

Tested on DB410c with WLAN SDIO card.

thanks,
srini
