[PATCH 0/3] Add R8A7792/Blanche PFC support

[PATCH 0/3] Add R8A7792/Blanche PFC support

[Sergei Shtylyov]

Hello.

   Here's the set of 3 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20160630-v4.7-rc5' tag. We're adding the R8A7792 PFC node and
the describe the pins for the SCIFs and SMSC LAN89218 Ethernet chip found on
the Blanche board). These patches depend on the R8A7792 PFC driver patchset
in order to work properly.

[1/3] ARM: dts: r8a7792: add PFC support
[2/3] ARM: dts: blanche: add SCIF pins
[3/3] ARM: dts: blanche: add Ethernet pins

WBR, Sergei

[PATCH 1/3] ARM: dts: r8a7792: add PFC support

[PATCH 3/3] ARM: dts: blanche: add Ethernet pins

[Sergei Shtylyov]

Add the (previously omitted) pin data for the SMSC LAN89218 Ethernet chip
to the Blanche board's device tree: the chip's IRQ output is connected to
the SoC's IRQ0 pin and its nCS input is connected to the SoC's EX_CS0# pin.
