2016-01-25driver/ddr/fsl: Add workaround for A009663Shengzhou Liu
Erratum A-009663 workaround requires to set DDR_INTERVAL[BSTOPRE] to 0 before setting DDR_SDRAM_CFG[MEM_EN] and set DDR_INTERVAL[BSTOPRE] to the desired value after DDR initialization has completed. When DDR controller is configured to operate in auto-precharge mode(DDR_INTERVAL[BSTOPRE]=0), this workaround is not needed.

2016-01-25armv8: fsl-lsch3: fixup SYSCLK frequency in device treePrabhakar Kushwaha
SYSCLK frequency is dependent on on-board switch settings. It may vary as per requirement. boot-loader is aware of board switch configurations. So Fixup Linux device tree from boot-loader.

2016-01-25fsl/ddr: Add workaround for ERRATUM_A009942Shengzhou Liu
During the receive data training, the DDRC may complete on a non-optimal setting that could lead to data corruption or initialization failure. Workaround: before setting MEM_EN, set DEBUG_29 register with specific value for different data rates.

2016-01-25bug.h: move BUILD_BUG_* defines to include/linux/bug.hMasahiro Yamada
BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

2016-01-25arm, powerpc: Update cc-version tests to check for cc-name as wellTom Rini

The management data input/output (MDIO) requires open-drain, i.MX7D TO1.0 ENET MDIO pin has no open drain, but TO1.1 supports this feature. So to TO1.1, need to enable open drain by setting bits GPR0[8:7] for TO1.1. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de>

This board includes an RK3288 SoC on a SOM. It can be mounted on a base-board which provides a wide range of peripherals. So far this is verified to boot to a prompt from a microSD card. The serial console works as well as HDMI. Thanks to Tom Cubie for sending me a board. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-01-21rockchip: jerry: Enable EDP and HDMI video outputSimon Glass
Enable these devices using the VOPL video output device. We explicitly disable VOPB in the device tree to avoid it taking over. Since this device has an LCD display this comes up by default. If the display fails for some reason then it will attempt to use HDMI. It is possible to force it to fail (and thus fall back to HDMI) by puting 'return -EPERM' at the top of rk_edp_probe(). For now there is no easy way to select between the two. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-01-21rockchip: video: Add a display driver for rockchip HDMISimon Glass
Some Rockchip SoCs support HDMI output. Add a display driver for this so that these displays can be used on supported boards. Unfortunately this driver is not fully functional. It cannot reliably read EDID information over HDMI. This seems to be due to the clocks being incorrect - the I2C bus speed appears to be up to 100x slower than the clock settings indicate. The root cause may be in the clock logic. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-01-21rockchip: clk: Make rkclk_get_clk() SoC-specificSimon Glass
The current method assumes that clocks are numbered from 0 and we can determine a clock by its number. It is safer to use an ID in the clock's platform data to avoid the situation where another clock is bound before the one we expect. Move the existing code into rk3036 since it still works there. Add a new implementation for rk3288. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-01-21rockchip: clock: Add a function to find a clock by IDSimon Glass

2016-01-21rockchip: Convert the PMU IOMUX registers into an arraySimon Glass
