2016-04-20ARM: dts: r8a7779: Correct interrupt type for ARM TWDGeert Uytterhoeven1-1/+1
The ARM TWD interrupt is a private peripheral interrupt (PPI), and per the ARM GIC documentation, whether the type for PPIs can be set is IMPLEMENTATION DEFINED. For R-Car H1 devices the PPI type cannot be set, and so when we attempt to set the type for the ARM TWD interrupt it fails. This has gone unnoticed because it fails silently, and because we cannot re-configure the type it has had no impact. Nevertheless fix the type for the TWD interrupt so that it matches the hardware configuration. Based on patches by Jon Hunter for Tegra20/30 and OMAP4.

2016-04-20ARM: shmobile: timer: Fix preset_lpj leading to too short delaysGeert Uytterhoeven1-17/+11
On all shmobile ARM SoCs, loop-based delays may complete early, which can be after only 1/3 (Cortex A9) or 1/2 (Cortex A7 or A15) of the minimum required time. This is caused by calculating preset_lpj based on incorrect assumptions about the number of clock cycles per loop: - All of Cortex A7, A9, and A15 run __loop_delay() at 1 loop per CPU clock cycle, - As of commit 11d4bb1bd067f9d0 ("ARM: 7907/1: lib: delay-loop: Add align directive to fix BogoMIPS calculation"), Cortex A8 runs __loop_delay() at 1 loop per 2 instead of 3 CPU clock cycles. On SoCs with Cortex A7 and/or A15 CPU cores, this went unnoticed, as delays use the ARM arch timer if available. R-Car Gen2 doesn't work if the arch timer is disabled. However, APE6 can be used without the arch timer. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

The official UDOO board kit has 7 and 15.6 inch touchscreen LCD panels as options. This patch adds support for 7 inch panel only, but the 15.6 inch one should be easy to add using the same regulator, backlight device and LVDS channel. Since this panel is an option for UDOO board it is disabled by default and can be enabled (for example) by the following U-Boot commands: fdt set backlight status okay fdt set panelchan status okay fdt set panel7 status okay fdt set touchscreenp7 status okay The LVDS channels is also disabled by default to avoid warning from its driver.

2016-04-18ARM: dts: lpc32xx: set default clock rate of HCLK PLLVladimir Zapolskiy1-0/+3
Probably most of NXP LPC32xx boards have 13MHz main oscillator and therefore for HCLK PLL and ARM core clock rate default hardware setting is 16 * 13MHz = 208MHz, however a user may vary HCLK PLL/ARM core rate from 156MHz to about 266MHz for 13MHz clock source. The change explicitly defines HCLK PLL output rate to default 208MHz to overwrite any settings done by a bootloader, if needed it can be redefined in a board DTS file.

DRA72-EVM now has an upgrade to Rev C with SR2.0 silicon. As part of this change, a few updates were factored in that were software incompatible with previous board in few areas: - We now use DP83867 ethernet phy instead of older DP838865 which fails in certain use cases. - Two Ethernet ports now instead of the single one in rev B. - polarities changed for certain pcf gpios - Due to SoC phy current requirements, VDDA supplies are split between ldo3 and ldo2 (ldo2 was previously unused). NOTE: DSS (VDDA_VIDEO) is still supplied by ldo5, HDMI is now supplied by LDO2 instead of using LDO3. NOTE: It does not make much sense to spin off a new board compatible flag since there is no real benefit for the same.
