pinctrl: uniphier: guard uniphier directory with CONFIG_PINCTRL_UNIPHIER

2016-03-08T16:11:04Z

CONFIG_PINCTRL_UNIPHIER is more suitable than CONFIG_ARCH_UNIPHIER to guard the drivers/pinctrl/uniphier directory. The current CONFIG_PINCTRL_UNIPHIER_CORE is a bit long, so rename it into CONFIG_PINCTRL_UNIPHIER. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: set input-enable before pin-muxing

2016-03-08T16:10:52Z

While IECTRL is disabled, input signals are pulled-down internally. If pin-muxing is set up first, glitch signals (Low to High transition) might be input to hardware blocks. Bad case scenario: [1] The hardware block is already running before pinctrl is handled. (the reset is de-asserted by default or by a firmware, for example) [2] The pin-muxing is set up. The input signals to hardware block are pulled-down by the chip-internal biasing. [3] The pins are input-enabled. The signals from the board reach the hardware block. Actually, one invalid character is input to the UART blocks for such SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the power on reset. To avoid such problems, pins should be input-enabled before muxing.

bug.h: move BUILD_BUG_* defines to include/linux/bug.h

2016-01-25T15:39:59Z

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.

Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52Z

After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag. Cc: Kate Stewart Signed-off-by: Tom Rini

ARM: uniphier: rename CONFIG_MACH_* to CONFIG_ARCH_UNIPHIER_*

I want these prefixed with CONFIG_ARCH_UNIPHIER_ to clarify they belong to UniPhier SoC family. Signed-off-by: Masahiro Yamada
