ARM: mach-shmobile: r8a7779: Minimal setup using DT
Allow a minimal setup of the r8a7779 SoC using a flattened device tree. In particular, configure the i2c and ethernet controllers using a flattened device tree. SCI serial controller and TMU clock source, whose drivers do not yet support configuration using a flattened device tree, are still configured using C code in order to allow booting of a board with this SoC. The ethernet controller also requires a regulator which is a board property. A sample snippet DT for the marzen board is as follows: /dts-v1/; /include/ "r8a7779.dtsi" / { fixedregulator3v3: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "fixed-3.3V"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-boot-on; regulator-always-on; }; }; &lan0 { vddvario-supply = <&fixedregulator3v3>; vdd33a-supply = <&fixedregulator3v3>; }; Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
