2013-06-27mmc: sdhci-esdhc: calculate sdclk divider from controller clockLucas Stach
The SDCLK is divided down from the host controller clock. Host controller clock may be different from the maximum SDCLK, so get it from the platform, instead of just using the max SDCLK.

2013-06-27mmc: card: fixing an false identification of SANITIZE commandYaniv Gardi
Inside the routine mmc_blk_ioctl_cmd() the sanitize command is identified according to the value of bits 16-23 of the argument. but what happens if a different command is sent, and only by chance, bits 16-23 contain the value of SANITIZE command ? In that case a SANITIZE command will be falsely identified. In order to prevent such a case, the condition is expanded and now it also checks the opcode itself, and verifies that it is an MMC_SWITCH opcode.

2013-06-27mmc: reordered shutdown sequence in mmc_bld_remove_reqPaul Taysom
We had a multi-partition SD-Card with two ext2 file systems. The partition table was getting overwritten by a race between the card removal and the unmount of the 2nd ext2 partition. What was observed: 1. Suspend/resume would call to remove the device. The clearing of the device information is done asynchronously. 2. A request is made to unmount the file system (this is called after the removal has started). 3. The remapping table was cleared by the asynchronous part of the device removal. 4. A write request to the super block (block 0 of the partition) was sent down and instead of being remapped to the partition offset, it was remapped to block 0 of the device which is where the partition table is located. 5. Write was queued and written resulting in the overwriting of the partition table with the ext2 super block. 6. The mmc_queue is cleaned up. The mmc card device driver used to access SD cards, was calling del_gendisk before calling mmc_cleanup-queue. The comment in the mmc_blk_remove_req code indicated that it expected del_gendisk to block all further requests from being queued but it doesn't. The mmc driver uses the presences of the mmc_queue to determine if the request should be queued. The fix was to clean up the mmc_queue before the rest of the the delete partition code is called. This prevents the overwriting of the partition table. However, the umount gets an error trying to write the super block. The umount should be issued before the device is removed but that is not always possible. The umount is still needed to cleanup other data structures.

2013-06-27mmc: sirf: fix sdhci_pltfm_init sequenceArnd Bergmann
Patch "mmc: sdhci: Add size for caller in init+register" changed the interface for sdhci_pltfm_init, while patch "mmc: sdhci-sirf: add mmc host sdhci-pltfm based driver for SiRF SoCs" added a new driver with the old interface. This changes the sirf driver to use the new interface, avoiding one warning, and simplifying the init sequence. Since we're here already, this also adds an error path for failed clk_prepare_enable.
