2018-05-02pinctrl: uniphier: add LD11 MPEG2-TS I/O pin-mux settingsKatsuhiro Suzuki
The MPEG2-TS input/output core both accepts serial TS and parallel TS. The serial TS interface uses following pins: hscin0_s : HS0DOUT[0-3] hscin1_s : HS0DOUT[4-7] hscin2_s : HS1BCLKIN, HS1SYNCIN, HS1VALIN, HS1DIN0 hscout0_s: HS0DOUT[0-3] hscout1_s: HS0DOUT[4-7] And the parallel TS interface uses following pins: hscin0_p : HS0BCLKIN, HS0SYNCIN, HS0VALIN, HS0DIN[0-7] hscin1_p : HS1BCLKIN, HS1SYNCIN, HS1VALIN, HS1DIN[0-7] hscout0_p: HS0BCLKOUT, HS0SYNCOUT, HS0VALOUT, HS0DOUT[0-7] Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Acked-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2017-10-31pinctrl: uniphier: remove eMMC hardware reset pin-muxMasahiro Yamada
This is handled by the mmc-pwrseq-emmc driver, which controls an eMMC hardware reset via a GPIO line. Remove it from the function pin-mux settings. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2017-08-14pinctrl: uniphier: omit redundant input enable bit informationMasahiro Yamada
For LD11/20 SoCs (capable of per-pin input enable), the iectrl bit number matches its pin number. So, this is redundant information. Instead, we just need a flag to know if the iectrl gating exists or not. With this refactoring, 5 bits in pin data will be saved.

2017-08-14pinctrl: uniphier: clean up GPIO port muxingMasahiro Yamada
There are a bunch of GPIO muxing data, but most of them are actually unneeded because GPIO-to-pin mapping can be specified by "gpio-ranges" DT properties. Tables that contain a set of GPIO pins are still needed for the named mapping by "gpio-ranges-group-names". This is a much cleaner way for UniPhier SoC family where GPIO numbers are not straight mapped to pin numbers.

The pingroups dump of debugfs hits WARN_ON() in pinctrl_groups_show(). Filling non-existing ports with '-1' turned out a bad idea.

2017-05-02Merge tag 'pinctrl-v4.12-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.12 cycle. The extra week before the merge window actually resulted in some of the type of fixes that usually arrive after the merge window already starting to trickle in from eager developers using -next, I'm impressed. I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal with the onset of Samsung patches. It works great. Apart from that it is a boring round, just incremental updates and fixes all over the place, no serious core changes or anything exciting like that. The most pleasing to see is Julia Cartwrights work to audit the irqchip-providing drivers for realtime locking compliance. It's one of those "I should really get around to looking into that" things that have been on my TODO list since forever. Summary: Core changes: - add bi-directional and output-enable pin configurations to the generic bindings and generic pin controlling core. New drivers or subdrivers: - Armada 37xx SoC pin controller and GPIO support. - Axis ARTPEC-6 SoC pin controller support. - AllWinner A64 R_PIO controller support, and opening up the AllWinner sunxi driver for ARM64 use. - Rockchip RK3328 support. - Renesas R-Car H3 ES2.0 support. - STM32F469 support in the STM32 driver. - Aspeed G4 and G5 pin controller support. Improvements: - a whole slew of realtime improvements to drivers implementing irqchips: BCM, AMD, SiRF, sunxi, rockchip. - switch meson driver to get the GPIO ranges from the device tree. - input schmitt trigger support on the Rockchip driver. - enable the sunxi (AllWinner) driver to also be used on ARM64 silicon. - name the Qualcomm QDF2xxx GPIO lines. - support GMMR GPIO regions on the Intel Cherryview. This fixes a serialization problem on these platforms. - pad retention support for the Samsung Exynos 5433. - handle suspend-to-ram in the AT91-pio4 driver. - pin configuration support in the Aspeed driver. Cleanups: - the final name of Rockchip RK1108 was RV1108 so rename the driver and variables to stay consistent" * tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (80 commits) pinctrl: mediatek: Add missing pinctrl bindings for mt7623 pinctrl: artpec6: Fix return value check in artpec6_pmx_probe() pinctrl: artpec6: Remove .owner field for driver pinctrl: tegra: xusb: Silence sparse warnings ARM: at91/at91-pinctrl documentation: fix spelling mistake: "contoller" -> "controller" pinctrl: make artpec6 explicitly non-modular pinctrl: aspeed: g5: Add pinconf support pinctrl: aspeed: g4: Add pinconf support pinctrl: aspeed: Add core pinconf support pinctrl: aspeed: Document pinconf in devicetree bindings pinctrl: Add st,stm32f469-pinctrl compatible to stm32-pinctrl pinctrl: stm32: Add STM32F469 MCU support Documentation: dt: Remove ngpios from stm32-pinctrl binding pinctrl: stm32: replace device_initcall() with arch_initcall() pinctrl: stm32: add possibility to use gpio-ranges to declare bank range pinctrl: armada-37xx: Add gpio support pinctrl: armada-37xx: Add pin controller support for Armada 37xx pinctrl: dt-bindings: Add documentation for Armada 37xx pin controllers pinctrl: core: Make pinctrl_init_controller() static pinctrl: generic: Add bi-directional and output-enable ...
