2012-02-19MFD: mcp-core: remove legacy driver suspend/resume methodsRussell King1-2/+0
The legacy driver suspend/resume methods are no longer used, so get rid of them. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: mcp/ucb1x00: separate ucb1x00 driver data from the MCP dataRussell King1-2/+1
Patch taken from 5dd7bf59e0 (ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp bus.) by Jochen Friedrich <jochen@scram.de>. This adds just the codec data part of the patch. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-03MFD: mcp-sa11x0: remove DMA initializers and variablesRussell King1-6/+0
The dma_device_t variables are only ever written to by mcp-sa11x0 and never read. As the old SA11x0 DMA support will be removed, remove these so that it no longer depends on the old SA11x0 DMA definitions.

2012-02-03MFD: mcp-core: sanitize host creation/removalRussell King1-2/+3
host_unregister() gives us no chance between removing the device and the mcp data structure being freed to access the data inbetween, which drivers may need to do if they need to iounmap() pointers in their private data structures. Therefore, re-jig the interfaces, which are now, on creation: mcp = mcp_host_alloc() if (mcp) { ret = mcp_host_add(mcp, data); if (!ret) mcp_host_free(mcp); } and on removal: mcp_host_del(mcp); ... access mcp ... mcp_host_free(mcp); The free does the final put_device() on the struct device as one would expect.

2012-01-21MFD: mcp-core: fix mcp_priv() to be more type safeRussell King1-1/+4
mcp_priv() does unexpected things when passed a void pointer. Make it a typed inline function, which ensures that it works correctly in these cases. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

bus." This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register.

2009-11-27add gpiolib support to ucb1x00Thomas Kunze1-0/+1
The old access methods to the gpios will be removed when all users has been converted. (mainly ucb1x00-ts)
2009-11-27move drivers/mfd/*.h to include/linux/mfdThomas Kunze1-0/+68
So drivers like collie_battery driver can use those files easier.
