* T4/usb: move usb 2.0 utmi dual phy init code to cpu_init.cRoy Zang2013-05-14-21/+0
| | | | | | | | This is what we have done for the UTMI PHY on P3041/P5020. Then the PHY initialization can be reused in kernel without “usb start” command. Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-0/+365
| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| * mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou2013-05-06-32/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of time that MMC driver spends on initializing a device is polling OCR (operation conditions register). To decouple this polling loop, device init is split into two parts: The first part fires the OCR query command, and the second part polls the result. So the caller is now no longer bound to the OCR-polling delay; he may fire the query, go somewhere and then come back later for the result. To use this, call mmc_set_preinit() on any device which needs this. This can save significant amounts of time on boot (e.g. 200ms) by hiding the MMC init time behind other init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.
