2011-06-01ARM: OMAP4: MMC: increase delay for pbiasBalaji T K1-3/+10
4 micro seconds is not enough for PBIAS if MMC regulator is enabled from MMC regulator OFF. Increase the delay for PBIAS to stabilize. Wait for PBIAS and timeout if not. Resolves MMC/SD failure on OMAP4 "Pbias Voltage is not same as LDO" Signed-off-by: Balaji T K <balajitk@ti.com> Acked-by: Kishore Kadiyala <kishore.kadiyala@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2011-03-01OMAP: adapt hsmmc to hwmod frameworkKishore Kadiyala1-149/+197
OMAP2420 platform consists of mmc block as in omap1 and not the hsmmc block as present in omap2430, omap3, omap4 platforms. Removing all base address macro defines except keeping one for OMAP2420 and adapting only hsmmc device registration and driver to hwmod framework. Changes involves: 1) Remove controller reset in devices.c which is taken care of by hwmod framework. 2) Using omap-device layer to register device and utilizing data from hwmod data file for base address, dma channel number, Irq_number, device attribute. 3) Update the driver to use dev_attr to find whether controller supports dual volt cards Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Kishore Kadiyala <kishore.kadiyala@ti.com> Reviewed-by: Balaji T K <balajitk@ti.com> Cc: Benoit Cousson <b-cousson@ti.com> CC: Kevin Hilman <khilman@deeprootsystems.com> Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-10-08OMAP: control: move plat-omap/control.h to mach-omap2/control.hPaul Walmsley1-1/+1
Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

2010-10-01omap4 hsmmc: Register offset handlingkishore kadiyala1-0/+4
In OMAP4, as per new PM programming model, the legacy registers which were there in OMAP3 are all shifted by 0x100 while new one's are added from offset 0 to 0x10. For OMAP4, the register offset appending of 0x100 done in devices.c currently, is moved to driver file.This change fits in for current implementation as well as once the driver undergoes hwmod adaptation.

2010-02-15omap_hsmmc: Allow for a shared VccQAdrian Hunter1-0/+3
EMMC can have two voltage supplies, Vcc and VccQ which are implemented in the code as consumer supplies vmmc and vmmc_aux. If the regulator that supplies vmmc_aux is shared with other consumers, then sending it to sleep will disrupt those consumers. However, the TWL4030-family regulators may have OFF remapped to SLEEP, in which case 'regulator_disable()' will put the regulator to sleep only when all consumers are disabled - which is the desired behaviour. This patch adds a platform data field to allow that option. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-15omap_hsmmc: Allow for power saving without going offAdrian Hunter1-0/+3

2010-02-15omap: RX51: Remux to pull eMMC lines down when powering offAdrian Hunter1-0/+8
It has been discovered that, when eMMC is powered off, current will flow from OMAP eMMC data pull-ups to the eMMC voltage supply. Configuring pads for OMAP off-mode does not help because eMMC is powered off independently of OMAP off-mode. Hence the pads are now re-configured when eMMC is powered on or off.
