2012-09-01MX28: DMA: Prolong the DMA timeoutMarek Vasut
Load from SPI flash can create a long DMA chain, which can take long time to transfer. Change the DMA timeout to roughly 10s to prevent such long chains misreporting errors.

2012-09-01mx5: add iomux-mx51.h includeMatt Sealey
Allow usage of the imx-common/iomux-v3.h framework by including pad settings for the i.MX51. The content of the file is taken from Linux kernel at commit 5d23b39 plus the required changes to make it work in U-Boot. The contained pad settings are the minimum required to make an Efika MX boot and get all the currently-implemented peripherals working in U-Boot. It is recommended that this file not be just a dumping ground for pins but only contain the settings required for all the boards using it. Changes for v2: * reference commit id from Linux kernel * additionally roll in the USB pads * removed GPIO_NUMBER define Signed-off-by: Matt Sealey <matt@genesi-usa.com> Acked-by: Stefano Babic <sbabic@denx.de>
2012-09-01mxs: Rename 'mx28_dram_init' to 'mxs_dram_init'Otavio Salvador

2012-09-01mxc: Make gpio_get_value() use PSRBenoît Thébaudeau
gpio_get_value() should use PSR like Linux, not DR, because DR does not always reflect the pin state, while PSR does. This is especially useful to detect a short circuit on a GPIO pin configured as output, or to read the level of a pin controlled by a non-GPIO IOMUX function.

2012-09-01spi: fix mxs_spi_slave structure allocation to clear memoryMatt Sealey
Use calloc() instead of malloc() to allocate the mxs_spi_slave structure. Clearing the memory is necessary since most of the time this gets done super early in boot, but on warm reboots, and when SPI probing is done long after the init stages it could actually pick up previously used memory, and things like the chipselect polarity and other data end up being filled with trash data if not explicitly set by the board files. This solves a semi-random, almost unreproducable error whereby SPI devices act very, very strangly on boot. Signed-off-by: Matt Sealey <matt@genesi-usa.com> Acked-by: Stefano Babic <sbabic@denx.de>
