When a GPIO is handled by a separate driver the pinmux gpio_set_direction() handler won't be called. The pin mux type then need to be configured to GPIO at request time.

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.

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.

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.

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.

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.

R-Car H1 has many clocks, and it is possible to read/use clock ratio of these clocks from FRQMRx as DIV4 clocks. But, these ratio are fixed value and these are decided by MD pin status. This means that we can use fixed ratio clock via MD pin status, instead of DIV4 clocks. This patch reads MD pin status, and sets PLLA clock (= root clock), and used fixed ratio clock for other clocks. It was tesed on marzen board.

With the added capabilty of the intc_irqpin driver to handle shared external IRQs, all prerequisites are fulfilled and we are ready to migrate completely to GIC. This includes the following steps: - Kconfig: select ARM_GIC and RENESAS_INTC_IRQPIN - intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need to mask out all shared IRQs as it is needed by the shared intc_irqpin driver. - setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update all IRQ numbers to point to the GIC SPI. - board-armadillo: Update all IRQ numbers to point to the GIC SPI. - pfc-r8a7740: Update all IRQ numbers of the GPIOs to point to the GIC SPI.

Add DT nodes for the 4 irqpin interrupt controllers on sh73a0. We add them to sh73a0.dtsi, which is also used by configurations, doing all their device instantiation from board the .c code.
