| | * mmc: mxs-mmc: Check the return value from stmp_reset_block()Fabio Estevam2013-08-241-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | stmp_reset_block() may fail, so let's check its return value and propagate it in the case of error. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Chris Ball <cjb@laptop.org>
| | * mmc: mxs-mmc: Use devm_clk_get()Fabio Estevam2013-08-241-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using devm_clk_get() allows us to remove the clk_put() calls, so let's use it to simplify the code. Rename the 'out_clk_put' label to 'out_clk_disable' now that clk_put is removed.

| | * mmc: jz4740: fix return value check in jz4740_mmc_probe()Wei Yongjun2013-08-241-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Also there is already a error message within devm_ioremap_resource(), so remove the dev_err call to avoid redundant error message.

In some extreme situation, the rx phase point produced by the following tuning process will drift quite a distance. Before tuning UHS card, this patch will set a more proper initial tx phase point, which is calculated from statistic data, and can achieve a much better tx signal quality.

Again, a bit of domain overlap with SoC and DT branches, but most of this is around legacy code and board support. We've found that platform maintainers have a hard time separating all of these out and might move towards fewer branches for next release. - Removal of a number of Marvell Kirkwood board files, since contents is now common and mostly configured via DT. - Device-tree updates for Marvell Dove, including irqchip and clocksource setup. - Defconfig updates. Gotta go somewhere. One new one for Renesas Lager. - New backlight drivers for backlights used on Renesas shmobile platforms. - Removal of Renesas leds driver. - Shuffling of some of the new Broadcom platforms to give room for others in the same mach directory.

| * | | mmc: esdhc: Add support for 8-bit bus width and non-removable cardOded Gabbay2013-07-052-1/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support of connecting an MMC media using an 8-bit bus width connection to Freescale's P2020 H/W SDHC controller. During the probe function, the generic function mmc_of_parse is called to detect whether the controller is configured with 8-bit bus width. Also, the generic function detects if the non-removable property is set in the device tree. The function esdhc_pltfm_bus_width was added because the bus width configuration is platform specific.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The field containing the production date in the CID register only uses 4 bits to encode the year, starting from 1997 in the original standard. In 2013, the production year field contains 0, and the kernel reports a 1997 production date. The eMMC 4.51 specification adds a new interpretation rule. For all devices implementing the 4.41 specification or later, the production year field will be interpreted as a value between 2010 and 2025, with 0 corresponding to 2013.

When pm_runtime_set_autosuspend_delay() was being called, the device's usage counter was 0, causing the PM layer to runtime-suspend the device. We then went on to call sdhci_add_host() on a suspended device, which hung. Fix this by making the driver consistent with the omap_hsmmc driver, both in terms of runtime PM initialization and error handling. Now the device is not runtime-suspended until we exit the probe routine. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Chris Ball <cjb@laptop.org>

If the host is able to cut buth vcc and vccq, the MMC_CAP2_POWEROFF_NOTIFY shall be set. It will mean the card will be completely powered down at suspend and the power off notification cmd will be sent prior power down. It seems common not being able to cut both vcc and vccq for a host. In this situation we issue the sleep cmd in favor of the power off notification cmd, to save more power. While maintainng the above policy, we also want to make use of the power off notification in the shutdown sequence, even in the case were the host has not set MMC_CAP2_POWEROFF_NOTIFY, since we know vcc and vccq will regardless be cut. We accomplish this by always enabling the power off notification byte in the EXT_CSD and issue the power off notification when either MMC_CAP2_POWEROFF_NOTIFY is set or we are executing a shutdown.
