V2 of code to add GPIO -> IRQ mappings to the PFC table for the r8a73a4 SoC. Requires the IRQs to be mapped at a fixed location in Linux IRQ space. The actual IRQs are not handled by the PFC, instead IRQC is used on r8a73a4. Signed-off-by:

Add initial PFC support for the r8a73a4 SoC. At this point only GPIO interface is supported, move to newer interfaces planned as incremental changes. Original authors are Morimoto-san with help from Yoshii-san, thanks to them for the heavy lifting. Adjusted by Magnus to work together with updated code in drivers/pinctrl. Signed-off-by:

Boards/platforms that register dedicated GPIO devices will not supply a memory resource for GPIOs. Try to locate the GPIO memory resource at initialization time, and skip registration of the gpiochip if the resource can't be found. This is a temporary modification to ease the transition to separate GPIO drivers. It should be reverted when all boards and platforms will have been moved. Signed-off-by:

When implemented as a separate IP block, GPIOs should be handled by a separate driver. To make this possible GPIO support needs to be optional in the sh-pfc driver. If no GPIO data registers are supplied in the SoC information structure skip registration of the gpiochip. Signed-off-by:

The target is to get rid of function GPIOs completely. To reach this, make function GPIOs support optional by skipping the function GPIO chip registration if no function GPIOS are defined in SoC data. Signed-off-by:

This patch is V3 of a GPIO driver for the R-Car series of SoCs from Renesas. This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch. Signed-off-by:

Add IRQC interrupt controller support to r8a7790 by hooking up a single IRQC instances to handle 4 external IRQ signals. The IRQC controller is tied to SPIs of the GIC. On r8a7790 the external IRQ pins routing is handled by the PFC which is excluded from this patch. Both platform devices and DT devices are added in this patch. The platform device versions are used to provide a static interrupt map configuration for board code written in C. Signed-off-by:
