2013-03-19sf: Enable FDT-based configuration and memory mappingSimon Glass
Enable device tree control of SPI flash, and use this to implement memory-mapped SPI flash, which is supported on Intel chips. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19x86: spi: Set maximum write size for ICHSimon Glass
This SPI controller can only write 64 bytes at a time. Add this restriction in so that 'sf write' works correct for blocks larger than 64 bytes. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19sf: Respect maximum SPI write sizeSimon Glass
Some SPI flash controllers (e.g. Intel ICH) have a limit on the number of bytes that can be in a write transaction. Support this by breaking the writes into multiple transactions. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19x86: spi: Add Intel ICH driverSimon Glass
This supports Intel ICH7/9. The Intel controller is a little unusual in that it is mostly intended for use with SPI flash, and has some optimisations and features specifically for that application. In particular it is not possible to support ongoing transactions that continue over many calls with SPI_XFER_BEGIN and SPI_XFER_END. This driver supports writes of up to 64 bytes at a time, the limit for the controller. Future work will improve this.

2013-03-19sf: Use spi_flash_alloc() in each SPI flash driverSimon Glass
Rather than each device having its own way to allocate a SPI flash structure, use the new allocation function everywhere. This will make it easier to extend the interface without breaking devices. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-19sf: Add spi_flash_alloc() to create a new SPI flash structSimon Glass
At present it is difficult to extend the SPI flash structure since all devices allocate it themselves, and few of them zero all fields. Add a new function spi_flash_alloc() which can be used by SPI devices to perform this allocation, and thus ensure that all devices can better cope with SPI structure changes. Signed-off-by: Simon Glass <sjg@chromium.org>

Rather than each driver having its own way to allocate a SPI slave, use the new allocation function everywhere. This will make it easier to extend the interface without breaking drivers. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-03-18usb: ehci: Support interrupt transfers via periodic listPatrick Georgi
Interrupt transfers aren't meant to be used from the async list (the EHCI spec indicates trouble with low/full-speed intr on async). Build a periodic list instead, and provide an API to make use of it. Then, use that API from the existing interrupt transfer API. This provides support for USB keyboards using EHCI. Use timeouts to ensure we cannot get stuck in the keyboard scanning if something wrong happens (USB device unplugged or fatal I/O error) Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Signed-off-by: Julius Werner <jwerner@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

2013-03-18usb:composite:fix Provide function data when addressing device with only one ↵Lukasz Majewski
interface This commit fixes problems with some non-standard requests send with device address instead of interface address (bmRequestType.Receipent field). This happens with dfu-util (debian version: 0.5), which address non standard requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device. Without this fix, the above request is STALLED, and hence causes dfu-util to assume some standard configuration (packet size = 1024B instead of 4096B) In turn it displays following errors: Error obtaining DFU functional descriptor Warning: Assuming DFU version 1.0 Warning: Transfer size can not be detected ... Warning: Trying default transfer size 1024 This fix allows passing non-standard request to function setup code, where it shall be handled.

2013-03-14mmc: Tegra: Add SD bus power/voltage function and MMC pad init call.Tom Warren
Tegra30 requires the SD Bus Voltage & Power bits be set in the SD Power Control register. Tegra20 works w/o them set, but do it anyway for those SoCs as it's part of the SD spec. Also call a common board pad init routine (pad_init_mmc) in mmc_reset(), used by Tegra30 only for now. Note that Tegra20 SD/MMC HW differs enough from Tegra20 that a new compatible entry is used in the fdt compat_names/id tables.

T114 has a slightly different I2C clock, with a new (extra) divisor in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C clock is 100KHz +/- 3Hz on my Saleae Logic analyzer. Added a new entry in compat_names for T114 I2C since it differs from the previous Tegra SoCs. A flag is set when T114 I2C HW is found so new features like the extra clock divisor can be used.

This moves the Tegra USB implementation into the drivers/usb/host directory. Note that this merges the old /arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code changes, just moving stuff around. v2: While at it also move some defines and the usb.h header file to make usb driver usable for Tegra30. NOTE: A lot more work is required to properly init the PHYs and PLL_U on Tegra30, this is just to make porting easier and it does no harm here.

2013-03-12I2C: S3C24X0: Bug fixes in i2c_transferRajeshwari Shinde
This patch corrects the following issues 1) Write the correct M/T Stop value to I2CSTAT after i2c write. According to the spec, after finish the data transmission, we should write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA). 2) Not split the write to I2CSTAT into 2 steps in i2c read. According to the spec, we should write the combined M/R Start value to I2CSTAT after setting the slave address to I2CDS 3) Fix the mistake of making an equality check to an assignment. In the case of I2C write with the zero-length address, while tranfering the data, it should be an equality check (==) instead of an assignment (=).

2013-03-08omap3: allow dynamic selection of gfx_formatNikita Kiryanov
Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded in the code. This forces anyone who wants to use a different gfx_format to make adjustments after calling omap3_dss_panel_config(). This could be avoided if the value of gfx_format were parameterized as input for omap3_dss_panel_config(). Make gfx_format a field in struct panel_config, and update existing structs to set this field to the value that was originally hard coded.
