2010-02-15omap: Rename mmc-twl4030 files to hsmmcAdrian Hunter1-252/+0
mmc-twl4030.[ch] no longer has any dependency on twl4030 and should be renamed to reflect that. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-15omap_hsmmc: Move gpio and regulator control from board fileAdrian Hunter1-321/+31
This patch moves the setup code for GPIO's and Voltage Regulators from the board file mmc-twl4030.c to the driver omap_hsmmc.c. PBIAS and other system control configuration remains in the board file. Moving GPIO code to the driver makes the board initialisation code independent of when GPIO's are defined. That makes the board initialisation now entirely independent of its original twl4030 roots. Moving Voltage Regulator code to the driver allows for further development of regulator support in the core MMC code. It also permits the MMC core to be compiled as a module, because the board code no longer calls MMC core functions.

2010-02-10OMAP: hsmmc: fix memory leakAaro Koskinen1-1/+6
The platform data allocated with kmalloc() will become unreachable once the init is complete, so it should be freed. The problem was discovered by kmemleak.

2009-09-23ARM: OMAP: mmc-twl4030: add context loss counter supportDenis Karpov1-0/+15
PM dynamic OFF state results in context loss. That is, the host controller has been powered off at some point, which means the registers have been reset. The driver must detect when this happens, and restore the context. This patch adds the means to detect context loss. Note, the PM side is not yet implemented.

twl_mmc_cleanup() must free up the regulators that were allocated by twl_mmc_late_init(). This eliminates the below error when 'omap_hsmmc' module is repeatedly loaded and unloaded.

2009-05-28ARM: OMAP3: mmc-twl4030 uses regulator frameworkDavid Brownell1-167/+113
Decouple the HSMMC glue from the twl4030 as the only regulator provider, using the regulator framework instead. This makes the glue's "mmc-twl4030" name become a complete misnomer ... this code could probably all migrate into the HSMMC driver now. Tested on 3430SDP (SD and low-voltage MMC) and Beagle (SD), plus some other boards (including Overo) after they were converted to set up MMC regulators properly. Eventually all boards should just associate a regulator with each MMC controller they use. In some cases (Overo MMC2 and Pandora MMC3, at least) that would be a fixed-voltage regulator with no real software control. As a temporary hack (pending regulator-next updates to make the "fixed.c" regulator become usable) there's a new ocr_mask field for those boards.

Device connected to MMC3 is assumed to be self-powered, so set_power() function is empty. It can't be omited because host driver requires it.

2009-03-23ARM: OMAP3: mmc-twl4030 voltage cleanupDavid Brownell1-47/+80
Correct twl4030 MMC power switching: fix voltage ranges reported for each slot, and handle them fully. Lies corrected: - MMC-1 doesn't support the 2.6-2.7 Volt range - MMC-2 can't normally support anything except 1.8V Omissions corrected - MMC-1 *does* handle the 2.8-2.9 Volt range - MMC-2 can handle 2.5-3.2 Volt cards, given a transceiver Add transciever support for MMC-2; enable it for Overo and Pandora. (Depends on something else to have set up pinmuxing for control signals instead of as MMC2_DAT4..7 pins.) Also shrink twl4030_hsmmc_info a smidgeon ... padding is all gone.
