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>;
};
