* mci: s3c: fix providing info callbackUwe Kleine-König2018-08-081-1/+1
| | | | | | | | | There is no symbol iCONFIG_MCI_INFO, CONFIG_MCI_INFO makes sense here and matches what was added in the same commit to other drivers. Fixes: 73b0d228e5b0 ("driver: Attach info callback to device, not to driver") Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* resource: Let dev_request_mem_region return an error pointerSascha Hauer2014-09-161-0/+4

* driver: Attach info callback to device, not to driverSascha Hauer2013-05-301-5/+3
| | | | | | | | Since the info is device specific and not driver specific, attach the callback to the device. This makes it possible to have a info callback for a device which does not have a driver attached. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-171-4/+0
| | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: Use struct mci for internal argument passingSascha Hauer2012-02-091-0/+3
| | | | | | | | | The mci layer currently passes around a struct device_d for its internal use. Apart from being confusing this drops typesafety for no good reason. Instead, pass around a struct mci. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: remove unused device argument from set_iosSascha Hauer2012-02-091-3/+1
| | | | | | This argmuent is unused in all drivers, so remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci s3c: pass around the right pointerSascha Hauer2012-02-091-58/+45
| | | | | | | | The s3c driver passes around a struct device_d * internally in which it is never interested in. Instead pass around a struct s3c_mci_host and get rid of all this ugly void * derefs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci s3c: allocate host struct dynamicallySascha Hauer2012-02-091-26/+17
| | | | | | | | Yes, it does make sense. First there will always be the next hardware which has multiple controllers. Also, we shouldn't give bad examples to others. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci s3c: Do not mess with struct mci_hostSascha Hauer2012-02-091-6/+3
| | | | | | | This structure is owned by the core, do not change its contents in the driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci core: replace discrete ios values with struct iosSascha Hauer2012-02-091-7/+8
| | | | | | | As we'll need more arguments to set_ios over time put them in a struct mci_ios like the kernel does. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* MACH SAMSUNG/S3C: Separate S3C24XX clock managementJuergen Beisert2012-01-021-5/+5
| | | | | | | | | | There are major differences in the clock tree of the S3C24xx family and the more recent CPUs of the S3C family. Keep the S3C24XX clock routines separate to avoid an ifdef hell. But also use generic function names to be able to share drivers among the S3C family. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add S3C2440 MCI card supportJuergen Beisert2010-10-111-0/+817
Adding MCI card support for S3C2440 CPUs. This is for reference only, as there is currently no user in the barebox tree. Maybe one with access to the A9M2440 development kit can check it on his/her system. Checked here with my own S3C2440 based system which is not in the barebox tree.
