2015-10-02pinctrl: sh-pfc: Initial R8A7795 PFC supportTakeshi Kihara
Add PFC base support for the R8A7795 SoC.

2015-08-24pinctrl: sh-pfc: Implement pinconf power-source param for voltage switchingBen Hutchings
The pfc in the R8A7790 (and probably others in the R-Car gen 2 family) supports switching SDHI signals between 3.3V and 1.8V nominal voltage, and the SD driver should do that when switching to and from UHS modes. Add a flag for pins that have configurable I/O voltage and SoC operations to get and set the nominal voltage. Implement the pinconf power-source parameter using these operations.

2015-07-16pinctrl: sh-pfc: Accept standard function, pins and groups propertiesLaurent Pinchart
The "function", "pins" and "groups" pinmux and pinctrl properties have been standardized. Support them in addition to the custom "renesas,*" properties. New-style and old-style properties can't be mixed in DT. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-06-16pinctrl: sh-pfc: add R8A7794 PFC supportHisashi Nakamura
Add PFC support for the R8A7794 SoC including pin groups for some on-chip devices such as ETH, I2C, INTC, MSIOF, QSPI, [H]SCIF... Sergei: squashed together several patches, fixed the MLB_CLK typo, added IRQ4.. IRQ9 pin groups, fixed IRQn comments, added ETH B pin group names, removed stray new line and fixed typos in the comments in the pinmux_config_regs[] initializer, removed the platform device ID, took into account limited number of signals in the GPIO1/5/6 controllers, added reasonable and removed unreasonable copyrights, modified the bindings document, renamed, added changelog. Changes in version 5: - resolved rejects, refreshed the patch; - added Laurent Pinchart's ACK. Changes in version 4: - reused the PORT_GP_26() macro to #define PORT_GP_28(). Changes in version 3: - removed the platform device ID; - added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the CPU_ALL_PORT() macro. Changes in version 2: - rebased the patch.

2013-12-12sh-pfc: Support GPIO to IRQ mapping specified IRQ resourcesLaurent Pinchart
On non-DT platforms IRQ controllers associated with the GPIOs have a fixed IRQ base value known at compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values are dynamic in that case. Fix this by specifying IRQs associated with GPIOs in IRQ resources, populated automatically from the device tree. When IRQ resources are specified the driver requires one IRQ resource per GPIO able to generate an interrupt, and uses the translation table to compute the IRQ resource offset instead of the IRQ number.

2013-06-18sh-pfc: Add DT supportLaurent Pinchart
Support device instantiation through the device tree. The compatible property is used to select the SoC pinmux information. Set the gpio_chip device field to the PFC device to enable automatic GPIO OF support.
