* mmc: tmio: remove unused and deprecated symbolsGuennadi Liakhovetski2013-02-241-18/+0
| | | | | | | | The tmio_mmc_cd_wakeup() inline function has been deprecated since 3.4 and is unused since 3.4 too. Remove them. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
* mmc: tmio: support caps2 flagsGuennadi Liakhovetski2012-07-211-0/+1
| | | | | | | | Allow tmio mmc glue drivers to pass mmc_host::caps2 flags down to the mmc layer. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
* mmc: tmio: add callbacks to enable-update and disable the interface clockGuennadi Liakhovetski2012-07-211-0/+3
| | | | | | | | Every time the clock is enabled after possibly being disabled, we have to re-read its frequency and update our configuration. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
* mmc: tmio_mmc: power status flag doesn't have to be exposed in platform dataGuennadi Liakhovetski2012-03-271-1/+0
| | | | | | | | | The controller power status flag does not have to be accessed from the hot-plug detection code any more, it can now be removed from the platform data and put in the controller private struct.

* mmc: tmio_mmc: support the generic MMC GPIO card hotplug helperGuennadi Liakhovetski2012-03-271-6/+19
| | | | | | | | If the platform specifies the TMIO_MMC_HAS_COLD_CD flag, use the generic MMC GPIO card hotplug helper. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
* mmc: sdhi: Add write16_hookSimon Horman2011-07-201-0/+8
| | | | | | | | | | | | Some controllers require waiting for the bus to become idle before writing to some registers. I have implemented this by adding a hook to sd_ctrl_write16() and implementing a hook for SDHI which waits for the bus to become idle.

* mmc: tmio: runtime suspend the controller, where possibleGuennadi Liakhovetski2011-05-241-0/+17
| | | | | | | | | | | The TMIO MMC controller cannot be powered off to save power, when no card is plugged in, because then it will not be able to detect a new card-insertion event. On some implementations, however, it is possible to switch to using another source to detect card insertion. This patch adds support for such implementations.

* mmc: tmio_mmc: implement SDIO IRQ supportArnd Hannemann2011-01-081-0/+4
| | | | | | | | | | This patch implements SDIO IRQ support for mfds which announce the TMIO_MMC_SDIO_IRQ flag for tmio_mmc. If MMC_CAP_SDIO_IRQ is also set SDIO IRQ signalling is activated. Tested with a b43-based wireless SDIO card and sh_mobile_sdhi. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Chris Ball <cjb@laptop.org>
* mmc: tmio_mmc: implement a bounce buffer for unaligned DMAGuennadi Liakhovetski2011-01-081-0/+1
| | | | | | | | | | | | | | For example, with SDIO WLAN cards, some transfers happen with buffers at odd addresses, whereas the SH-Mobile DMA engine requires even addresses for SDHI. This patch extends the tmio driver with a bounce buffer, that is used for single entry scatter-gather lists both for sending and receiving. If we ever encounter unaligned transfers with multi-element sg lists, this patch will have to be extended. For now it just falls back to PIO in this and other unsupported cases.

* mmc: Allow 2 byte requests in 4-bit mode for tmio_mmcYusuke Goda2010-10-291-0/+5
| | | | | | | | | | | | | Adjust the tmio_mmc block size check to accept 2-byte requests in 4-bit mode if the hardware supports it. Tested with the SDHI hardware block included in sh7724.

* mmc: Allow the tmio_mmc mfd driver to specify get_cd handlerArnd Hannemann2010-10-291-0/+1
| | | | | | | | | | Some controllers, supported by the tmio_mmc driver do not have the card detect pin of a slot connected, so that polling needs to be used and card detection is handled by other means. This patch exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

* tmio: add a platform flag to disable card write-protection detectionGuennadi Liakhovetski2010-05-221-0/+4
| | | | | | | | | | Write-protection status is not always available, e.g., micro-SD cards do not have a write-protection switch at all. This patch adds a flag to let platforms force tmio_mmc to consider the card writable.

| | | | | | | | | | After this patch, if the "dma" pointer in struct tmio_mmc_data is not NULL, it points to a struct, containing two tokens, that have to be passed to the dmaengine driver for channel configuration.

* tmio_mmc: Remove const from platform data V3Magnus Damm2010-03-071-1/+1
| | | | | | | | | | Remove const from the tmio-mmc platform data hclk V3.

* mfd: tmio_mmc hardware abstraction for CNF areaIan Molton2010-01-181-0/+39
| | | | | | | | | | | | This patch abstracts out the CNF area code from tmio_mmc which is not present in all hardware that can use this driver. This is required so that we can support non-toshiba based hardware.

With this patch, the MFD driver provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.
