For regulator vmmc/vmmcq, use voltage range as below 3.3v/3.0v: (2.7v, 3.6v) 1.8v: (1.7v, 1.95v) Original code uses the precise value which may fail in regulator driver if it does NOT support the precise voltage.

Enable the quirk SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN since SD_CAPABILITIES_1[15:8](BASE_FREQ) can't get correct base clock value. It returns a fixed pre-set value like 200 on some sdhci-pxav3 based platforms like MMP3 while return 0 on the other sdhci-pxav3 based platforms. So we enable the quirk and get the base clock via function get_max_clock. Also add get_max_clock.

2012-12-06mmc: sdio: Use multiple scatter/gather listKyoungil Kim
Before this patch, we always used only single sg entry for SDIO transfer. This patch switches to using multiple sg entries. In the case of dwmci, it supports only up to 4KB size per single sg entry. So if we want to transfer more than 4KB, we should send more than 1 command. When we tested before applying this patch, it took around 335 us for 5K(5120) bytes transfer with dwmci controller. After applying this patch, it takes 242 us for 5K bytes. So this patch makes around 38% performance improvement for 5K bytes transfer. If the transfer size is bigger, then the performance improvement ratio will be increased. Signed-off-by: Kyoungil Kim <ki0351.kim@samsung.com> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-12-06mmc: core: Fix some driver hangs when dealing with broken devicesTrey Ramsay
There are infinite loops in the mmc code that can be caused by bad hardware. The code will loop forever if the device never comes back from program mode, R1_STATE_PRG, and it is not ready for data, R1_READY_FOR_DATA. A long timeout is added to prevent the code from looping forever. The timeout will occur if the device never comes back from program state or the device never becomes ready for data. It's not clear whether the timeout will do more than log a pr_err() and then start a fresh hang all over again. We may need to extend this patch later to perform some kind of reset of the device (is that possible?) or rejection of new I/O to the device.

The vmmc regulator enable in sdhci_add_host is NOT necessary since it can be enabled during mmc_power_up by function mmc_regulator_set_ocr. And this extra enable will make regulator_enable/regulator_disable unbalanced. Consequently, vmmc can't be disabled during mmc_power_off. Also, if the vqmmc regulator exists, it should be enabled regardless it support 1.8v or not.

2012-11-07mmc: sdhci: fix NULL dereference in sdhci_request() tuningChris Ball
Commit 473b095a72a9 ("mmc: sdhci: fix incorrect command used in tuning") introduced a NULL dereference at resume-time if an SD 3.0 host controller raises the SDHCI_NEEDS_TUNING flag while no card is inserted. Seen on an OLPC XO-4 with sdhci-pxav3, but presumably affects other controllers too. Signed-off-by: Chris Ball <cjb@laptop.org> Cc: stable <stable@vger.kernel.org> [3.3+]
