pinctrl: uniphier: support pin configuration

2017-02-22T23:37:56Z

Support the following DT properties: "bias-disable" "bias-pull-up" "bias-pull-down" "bias-pull-pin-default" "input-enable" "input-disable" My main motivation is to support pull up/down biasing. For Pro5 and later SoCs, the pupdctrl register number is the same as the pinmux number, so this feature can be supported without having big pin tables. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: fix unused-const-variable warnings for GCC 6.x

2016-10-18T05:06:46Z

Marek reports warnings in UniPhier pinctrl drivers when compiled by GCC 6.x, like: drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning: 'usb3_muxvals' defined but not used [-Wunused-const-variable=] static const int usb3_muxvals[] = {0, 0}; ^~~~~~~~~~~~ My intention here is to compile minimum set of pin data for SPL to save memory footprint, but GCC these days is clever enough to notice unused data arrays. We can fix it by sprinkling around __maybe_unused on those arrays, but I did not do that because they are counterparts of the pinctrl drivers in Linux. All the pin data were just copy-pasted from Linux and are kept in sync for maintainability. I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of *_pins and *_muxvals and set their sum to an unused struct member. This trick will satisfy GCC because the data arrays are used anyway, but such data arrays will be dropped from the final binary because the pointers to them are not used.

pinctrl: uniphier: add UniPhier sLD3 pinctrl driver

2016-09-18T14:10:17Z

Add pin-mux support for UniPhier sLD3 SoC. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: support 4bit-width pin-mux register capability

2016-09-18T14:10:11Z

On LD4 SoC or later, the pin-mux registers are 8bit wide, while 4bit wide on sLD3 SoC. Support it for the sLD3 pinctrl driver. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: move register base macros from header to .c file

2016-09-14T13:54:19Z

These macros are only referenced in pinctrl-uniphier-core.c, so they need not reside in a header file. Signed-off-by: Masahiro Yamada

pinctrl: uniphier: add System Bus pin-mux settings

2016-09-14T13:54:19Z

This is needed to get access to UniPhier System Bus (external bus). Signed-off-by: Masahiro Yamada

ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()

2016-07-23T15:13:10Z

This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada
