d93906b869 ARM: shmobile: r8a7790: Configure R-Car GPIO for IRQ_TYPE_EDGE_BOTH 
"gpio-rcar: Support IRQ_TYPE_EDGE_BOTH" adds support to the R-Car GPIO
driver for IRQ_TYPE_EDGE_BOTH. As hardware support for this feature is
not universal for all SoCs a flag, has_both_edge_trigger, has been
added to the platform data of the driver to allow this feature to be
enabled.

As the r8a7790 SoC hardware supports this feature enable it.

b9ffcc2b12 pinctrl: sh-pfc: r8a7779: Fix missing MOD_SEL2 entry 
The list of functions selected by the MOD_SEL2 register was missing
an entry. This caused all entries after this to modify the MOD_SEL2
register incorrectly.

This bug showed up when selecting i2c2_c pins on the Renesas Hurricane board.

This bug has been present since pinmux support was added for the
r8a7779 SoC by 881023d28b ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.

ea770ad2ec sh-pfc: sh73a0: Add VCCQ MC0 regulator 
The sh73a0 has an internal power gate on the VCCQ power supply for the
SDHI0 device that is controlled (for some strange reason) by a bit in a
PFC register. This feature should be exposed as a regulator.

As the same register is also used for pin control purposes there is no
way to achieve atomic read/write sequences with a separate regulator
driver. We thus need to implement the regulator here.
