The current mechanism is SDIO-only. This allows us to create function-specific quirks, without creating messy Kconfig dependencies, or polluting core/ with function-specific code. Change-Id: If31a151c20a8a1fddb0774674821e9fdc4aa61a0 Signed-off-by: Andrei Warkentin <andreiw@motorola.com>
2011-04-07mmc: add per device quirk placeholderPierre Tardy
Some cards have quirks valid for every platforms using current platform quirk hooks leads to a lot of code and debug duplication. So we inspire a bit from what exists in PCI subsystem and do our own per vendorid/deviceid quirk. We still drop the complexity of the pci quirk system (with special section tables, and so on). That can be added later if needed.

2011-03-25tegra: sdhci: enable write protection on sd cardsVishal Singh
Write protection was disabled in K36. Enabling this feature by storing the write protection GPIO pin number (wp_gpio) from platform_data for the device and reading this GPIO (whenever the card is inserted) to determine whether the card is write protected or not. Bug 686892.

2011-03-10sdhci-tegra: use tasklet for card detectionHarry Hong
If remove/insert sdcard continuously, kernel panic happened due to lock up at sdhci_card_detect_callback(). The problem was that sdhci_card_detect_callback() being called from interrupt context. This code uses interfaces that cannot be called while the kernel is atomic (no scheduling). With using tasklet rather than directly call, detection call will be scheduled. So tasklet will make sure of serialization for card detection interrupt calls.
