This is not a proper fix, but as this is rasperry pi specific kernel,
|
||||
we've applied this workaround for now.

Subject: [PATCH] mmc: spi: disable dma mapping code, as it does not work
|
||||
|
||||
since:
|
||||
commit 0589342c27944e50ebd7a54f5215002b6598b748
|
||||
Author: Rob Herring <rob.herring@calxeda.com>
|
||||
Date: Tue Oct 29 23:36:46 2013 -0500
|
||||
|
||||
of: set dma_mask to point to coherent_dma_mask
|
||||
|
||||
Platform devices created by DT code don't initialize dma_mask pointer to
|
||||
anything. Set it to coherent_dma_mask by default if the architecture
|
||||
code has not set it.
|
||||
|
||||
the mmc-spi driver no longer detects the sd-cards any longer.
|
||||
|
||||
This patch disables the offending section in mmc_spi
|
||||
so that the driver works again and detects the sd card normally.
|
||||
|
||||
There is no real negative impact as the spi-framework
|
||||
does no longer rely on driver-provided DMA mappings but
|
||||
maps the transfers transparently.
