| | * | Input: uinput - use memdup_user() and friendsDmitry Torokhov2011-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of open-coding copying of data structures from userspace use memdup_user() and strndup_user(). Note that this introduces change in behavior because driver used to truncate 'phys' longer than 1024 bytes, but now it will refuse to set 'phys' that long. Arguably trying to set such 'phys' is suspect anyways. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Platform data is supported to allow configuration of system parameters such as selection between four and five wire touchscreens and for specification of optional direct to CPU IRQs for sample availability and for pen down. Use of this feature for at least the data IRQ is strongly recommended. Thanks to Julien Boibessot for extensive testing and detailed feedback.

This solves the re-initialization during the power up sequence. The voltage may have been decreased due to the card accepts a lower voltage than the voltage used during the initialization sequence. We need to reset the voltage to by the host highest possible value since according to specification the initialization must always be done at high voltage.

| * | | | | mmc: mxs-mmc: add mmc host driver for i.MX23/28Shawn Guo2011-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the mmc host driver for Freescale MXS-based SoC i.MX23/28. The driver calls into mxs-dma via generic dmaengine api for both pio and data transfer. Thanks Chris Ball for the indentation patch.

Unlike the old one this one is always present in the tree, even if no DMA is implemented, hence we can remove all the #ifdefs in from the driver. The driver automatically switches to PIO mode if no DMA support or no suitable channel is available.
