2019-03-10x86: acpi: Add DMA descriptors for I2C1 on Intel TangierAndy Shevchenko
Intel Tangier SoC has a general purpose DMA which can serve to speed up communications on SPI and I2C serial buses. Provide DMA descriptors to utilize this capability in the future. Note, I2C6, which is available to user, has no DMA request lines connected. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2019-03-08fdt: Fix FIT header verification in mkimage and conduct same checks as bootmJordan Hand
FIT header verification in mkimage was treating a return code as a boolean, which meant that failures in validating the fit were seen as successes. Additionally, mkimage was checking all formats to find a header which passes validation, rather than using the image type specified to mkimage. checkpatch.pl checks for lines ending with '(' and alignment matching open parentheses are ignored to keep with existing coding style.

2019-03-04spi: Rename sun4i_spi.c into spi-sunxi.cJagan Teki
Now the same SPI controller driver is reusable in all Allwinner SoC variants, so rename the existing sun4i_spi.c into spi-sunxi.c which eventually look like a common sunxi driver.

2019-03-04spi: sun4: Add A31 spi controller supportJagan Teki
The usual SPI transmission protocol in Allwinner A10 and A31 controllers share similar context with minimal changes in register offsets along with few additional register bits on A31.

Clock disablement could be done while releasing the bus transfer, but the existing code doesn't disable the clocks it only taken care of clock enablement globally in probe. So to make a proper clock handling, the clocks should enable it in claim and disable it in release. This patch would also do that change, by enable and disable clock in proper order.

2019-03-04spi: sun4i: Poll for rxfifo to be filled upJagan Teki
To drain rx fifo the fifo need to poll for how much data has been filled up in rx fifo. To achieve this, the current code is using wait_for_bit logic on control register with exchange burst mode mask, which is not a proper way of waiting for fifo filled up.

2019-03-04spi: designware: Change include orderHoratiu.Vultur@microchip.com
With current order of include files, the file designware_spi.c can't see that the struct global_data has the member board_type when CONFIG_BOARD_TYPES is defined. By not seeing this then all the members are shifted in the struct global_data. So when the driver is trying to read from device tree blob, it would pass the wrong address to the function 'fdtdev_get_int'. This will make to use the default frequency 500000. The fix consists of changing the order of include files in designware_spi.c to include first common.h file.
