Subject: Generic MMC-over-SPI binding?
Date: Tue, 08 Jan 2008 15:22:00 +0100 [thread overview]
Message-ID: <47838708.5050008@hogyros.de> (raw)
Hi,
in an embedded system similar to the lite5200 board, there is an MMC
card socket connected to one of the PSCs. Ideally, I'd like to express
this fact via the device tree and have the kernel bind the mmc-spi
driver to the SPI interface, but I cannot find any place where to insert
this code that I feel comfortable with.
- It is not a board-specific thing, because any board can just use any
SPI bus for MMC.
- The mmc-spi driver appears to be platform independent, so I'm not
sure OF bindings should be added to it.
- The generic device tree scanning does not contain any special cases
yet, so I don't want to add one.
My current thought is to create a new driver that just handles MMC on
PSCs in SPI mode by gluing all the relevant drivers together, but that
doesn't seem optimal to me either.
Any ideas?
Simon
