2012-08-02mmc: sdhci-pci: CaFe has broken card detectionDaniel Drake
commit 55fc05b7414274f17795cd0e8a3b1546f3649d5e upstream. At http://dev.laptop.org/ticket/11980 we have determined that the Marvell CaFe SDHCI controller reports bad card presence during resume. It reports that no card is present even when it is. This is a regression -- resume worked back around 2.6.37. Around 400ms after resuming, a "card inserted" interrupt is generated, at which point it starts reporting presence. Work around this hardware oddity by setting the SDHCI_QUIRK_BROKEN_CARD_DETECTION flag. Thanks to Chris Ball for helping with diagnosis.

commit 66292ad92c6d3f2f1c137a1c826b331ca8595dfd upstream. The HSMCI operates at a rate of up to Master Clock divided by two. Moreover previous calculation can cause overflows and so wrong timeouts.

2012-03-12mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5Sascha Hauer
commit 5b6b0ad6e572b32a641116aaa5f897ffebe31e44 upstream. On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION command. This works for SD cards. However, with MMC cards the MMC_SET_BLOCK_COUNT command is used instead, but this needs the same handling. Fix MMC cards by testing for the MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53 board with a Transcend MMC+ card and eMMC. The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this is a regression for these boards introduced in 3.0; it should go to 3.0/3.1/3.2-stable.

commit ef8781989a1bcd05aa47e853917c37df44917194 upstream. Some callbacks are set too early -- i.e. we can have dma capabilities but we can't get a dma channel.

2011-10-26mmc: dw_mmc: modify DATA register offsetJaehoon Chung
In dw_mmc 2.40a spec, Data register's offset is changed. Before we used Data register offset 0x100. but if somebody uses a 2.40a controller, we must use 0x200 for Data register. This patch adds a version-id checking point and uses SDMMC_DATA(x) instead of SDMMC_DATA. It assumes 2.40a is the latest version.

2011-10-26mmc: core: Add Power Off Notify Feature eMMC 4.5Girish K S
This patch adds support for the power off notify feature, available in eMMC 4.5 devices. If the host has support for this feature, then the mmc core will notify the device by setting the POWER_OFF_NOTIFICATION byte in the extended csd register with a value of 1 (POWER_ON). For suspend mode short timeout is used, whereas for the normal poweroff long timeout is used.

2011-10-26mmc: sdhci-pci: add runtime pm supportAdrian Hunter
Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.
