Disable the MMC2 support for Zoom2/3. [Ghorai] Please let us know the EXT_CSD Rev you see in zoom3 and the exact problem. Because we never face any issue for eMMC in ZOOM3. Because we have the same eMMC device in 3630-SDP and could have the same problem. > > Signed-off-by: Madhusudhan Chikkature <madhu.cr@xxxxxx> > --- > arch/arm/mach-omap2/board-zoom-peripherals.c | 30 --------------------- > ----- > 1 files changed, 0 insertions(+), 30 deletions(-) > > diff --git a/arch/arm/mach-omap2/board-zoom-peripherals.c > b/arch/arm/mach-omap2/board-zoom-peripherals.c > index 6b39849..ac791d2 100644 > --- a/arch/arm/mach-omap2/board-zoom-peripherals.c > +++ b/arch/arm/mach-omap2/board-zoom-peripherals.c > @@ -102,10 +102,6 @@ static struct regulator_consumer_supply > zoom_vsim_supply = { > .supply = "vmmc_aux", > }; > > -static struct regulator_consumer_supply zoom_vmmc2_supply = { > - .supply = "vmmc", > -}; > - > /* VMMC1 for OMAP VDD_MMC1 (i/o) and MMC1 card */ > static struct regulator_init_data zoom_vmmc1 = { > .constraints = { > @@ -121,21 +117,6 @@ static struct regulator_init_data zoom_vmmc1 = { > .consumer_supplies = &zoom_vmmc1_supply, > }; > > -/* VMMC2 for MMC2 card */ > -static struct regulator_init_data zoom_vmmc2 = { > - .constraints = { > - .min_uV = 1850000, > - .max_uV = 1850000, > - .apply_uV = true, > - .valid_modes_mask = REGULATOR_MODE_NORMAL > - | REGULATOR_MODE_STANDBY, > - .valid_ops_mask = REGULATOR_CHANGE_MODE > - | REGULATOR_CHANGE_STATUS, > - }, > - .num_consumer_supplies = 1, > - .consumer_supplies = &zoom_vmmc2_supply, > -}; > - > /* VSIM for OMAP VDD_MMC1A (i/o for DAT4..DAT7) */ > static struct regulator_init_data zoom_vsim = { > .constraints = { > @@ -159,15 +140,6 @@ static struct omap2_hsmmc_info mmc[] __initdata = { > .gpio_wp = -EINVAL, > .power_saving = true, > }, > - { > - .name = "internal", > - .mmc = 2, > - .wires = 8, > - .gpio_cd = -EINVAL, > - .gpio_wp = -EINVAL, > - .nonremovable = true, > - .power_saving = true, > - }, > {} /* Terminator */ > }; > > @@ -183,7 +155,6 @@ static int zoom_twl_gpio_setup(struct device *dev, > */ > zoom_vmmc1_supply.dev = mmc[0].dev; > zoom_vsim_supply.dev = mmc[0].dev; > - zoom_vmmc2_supply.dev = mmc[1].dev; > > return 0; > } > @@ -241,7 +212,6 @@ static struct twl4030_platform_data zoom_twldata = { > .keypad = &zoom_kp_twl4030_data, > .codec = &zoom_codec_data, > .vmmc1 = &zoom_vmmc1, > - .vmmc2 = &zoom_vmmc2, > .vsim = &zoom_vsim, > > }; > -- > 1.6.3.3 > > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-omap" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
