Some eMMC and embedded SDIO devices are able to be initialized at 1.8V as well, but it is better to be safe.

2012-03-06mmc: mmci: Implement PM runtime callbacks to save powerUlf Hansson
In the runtime_suspend callback we make use of mmci_save to disable the VCORE regulator and the MCLK to decrease current consumption. At runtime resume, we use mmci_restore to re-enable the resourses again. From now on this will mean that especially the mmci_restore function must be fast to execute since otherwise request latency will be introduced. For the ARM Primcell PL180, the MMCIPOWER register is used to control an external power supply to the card. Thus we need to prevent the runtime callbacks from doing save and restore, otherwise the power to card will be cut. This is done by adding a new flag to the variant data.

2012-03-06mmc: Minimize resume-time by deferring resumeUlf Hansson
Typically an sd/mmc card takes around 200 - 1100 ms to initialize when the power to the card has been cut, which is what happens during a suspend/resume sequence. All device's resume time adds up to the total kernel resume time. Some use cases requires the kernel to be resumed fast, to be able to meet deadlines. One use case example is WLAN SOFT_AP, but there are certainly more. This patch schedules a delayed work to do a deferred resume of the mmc host, if the bus holds a card of SD or MMC type. The reason for not supporting SDIO and SDcombo cards at this stage, is because the SDIO API is synchronus, which complicates request locking mechanism when waiting for a deferred resume to be completed. While waiting for a deferred resume to be completed, detect works are prevented from doing a new rescan. If a mmcblk request arrives, the deferred resume will be synced immediately. The deferred resume is scheduled 3000 ms after the resume request arrived. The idea behind this timer value is to let the mmc host being able to accept a new suspend request before it has been deferred resumed and thus not increase the resume to suspend time if not really needed.

2012-03-06mmc: block: Remove use of mmc_blk_set_blksizeUlf Hansson
According to the specifications for SD and (e)MMC default blocksize (named BLOCKLEN in Spec.) must always be 512 bytes. Since we hardcoded to always use 512 bytes, we do not explicitly have to set it. Future improvements should potentially make it possible to use a greater blocksize than 512 bytes, but until then let's skip this.

2012-03-06MMCI: Increase max_segs from 16 to 128Ulf Hansson
A significant increase (10-20%) in performance throughput for USB mass storage is the reason for incrementing the value. By some reason the USB driver allocates buffers which requires a scattergather list to contain a lot more than 16 elements to get optimal performance. This change sets the maximum elements to 128. Tests with large reads and large writes (100 MiB) show that the throughput increase is significant for write (10% for this test) but not for read. Tests are run on a Linux host with ext4 FS on the gadget mass storage device. The sg-len still exceeds 16 for the read tests but the performance gain is low or nothing.

2012-03-06mmc: mmci: Change vdd_handler to a generic ios handlerUlf Hansson
The purpose of the vdd_handler does not make sense. We remove it and use a more generic approach instead. A new "ios" handler is thus added, the purpose of which e.g. can be to control GPIO pins to a levelshifter. Previously the vdd_handler was also used for making additional changes to the MMCIPOWER register bits. This option is now removed. This patch is based upon a patch from Sebastian Rasmussen.
