pinctrl: npcm: add NPCM7xx pin control driver

2018-05-18T08:34:22+00:00

Add Nuvoton BMC NPCM7xx pin controller driver. The NPCM7XX Pin Controller multi-function routed through the multiplexing block, Each pin supports GPIO functionality (GPIOx) and multiple functions that directly connect the pin to different hardware blocks.

pinctrl/amd: Fix build dependency on pinmux code

2017-10-18T07:38:29+00:00

commit 83b31c2a5fdd4fb3a4ec84c59a962e816d0bc9de upstream. The commit 79d2c8bede2c93f943 ("pinctrl/amd: save pin registers over suspend/resume") caused the following compilation errors: drivers/pinctrl/pinctrl-amd.c: In function ‘amd_gpio_should_save’: drivers/pinctrl/pinctrl-amd.c:741:8: error: ‘const struct pin_desc’ has no member named ‘mux_owner’ if (pd->mux_owner || pd->gpio_owner || ^ drivers/pinctrl/pinctrl-amd.c:741:25: error: ‘const struct pin_desc’ has no member named ‘gpio_owner’ if (pd->mux_owner || pd->gpio_owner || We need to enable CONFIG_PINMUX for this driver as well.

pinctrl: aspeed: Rework strap register write logic for the AST2500

2017-10-09T07:00:39+00:00

Yong Li found that writes to the AST2500 strapping register were not properly supported by the Aspeed pinctrl core and provided a patch to rectify the problem. Several revisions of the patch were posted and ultimately v4 should have been applied, however some unfortunate liberal application of tags on my part lead to confusion between v3[1] and v4[2]. Generate the diff between v3 and v4 to apply as a fixup patch.

pinctrl: aspeed: Fix ast2500 strap register write logic

2017-10-09T07:00:39+00:00

On AST2500, the hardware strap register(SCU70) only accepts write ‘1’, to clear it to ‘0’, must set bits(write ‘1’) to SCU7C Signed-off-by: Yong Li Reviewed-by: Andrew Jeffery Tested-by: Andrew Jeffery Signed-off-by: Linus Walleij (cherry picked from commit 1865af212dfa0819ca21c7e5c18c2a75202c1827) Signed-off-by: Joel Stanley

pinctrl: aspeed: g5: constify pinconf_ops, pinctrl_ops, and pinmux_ops structures

2017-10-09T07:00:38+00:00

These structures are only stored in fields of a pinctrl_desc structure (confops, pctlops, and pmxops) that are const. Make the structures const as well. Done with the help of Coccinelle.

pinctrl: aspeed: g5: Add USB device and host support

2017-10-09T07:00:38+00:00

Implement the AST2500 USB functions as described by the devicetree bindings. The AST2500 exposes five USB controllers through two USB ports. Similar to the AST2400, the pins exposing USB are outliers with respect to the rest of the pinmux as they not capable of GPIO.

pinctrl: aspeed: g4: Add USB device and host support

2017-10-09T07:00:38+00:00

Implement the AST2400 USB functions as described by the devicetree bindings. Three ports are fully documented in the datasheet and exposed through the bindings and pinctrl, though there are remnants of documentation for a fourth port muxed with GPIO pins GPIOQ6 and GPIOQ7. The implementation is updated to reflect this but the function and group are not exposed. Disregarding the mostly undocumented fourth port, the USB functions are an outlier with respect to the rest of the muxed functionality on the AST2400 as GPIO is not supported on these pins.

pinctrl/amd: save pin registers over suspend/resume

2017-09-27T12:43:12+00:00

commit 79d2c8bede2c93f9432d7da0bc2f76a195c90fc0 upstream. The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is unresponsive after suspend/resume. The following error appears during resume: i2c_hid i2c-ELAN1300:00: failed to reset device. The problem here is that i2c_hid does not notice the interrupt being generated at this point, because the GPIO is no longer configured for interrupts. Fix this by saving pinctrl-amd pin registers during suspend and restoring them at resume time. Based on code from pinctrl-intel.
