Define the generic R8A77970 parts of the I2C[0-4] device node. Based on the original (and large) patch by Daisuke Matsushita [off-list ref]. Signed-off-by: Vladimir Barinov <redacted> Signed-off-by: Sergei Shtylyov <redacted> --- Changes in version 2: - made use of the SYSC power domain #define's; - moved the I2C nodes before HSCIF nodes. arch/arm64/boot/dts/renesas/r8a77970.dtsi | 88 ++++++++++++++++++++++++++++++ 1 file changed, 88 insertions(+) Index: renesas/arch/arm64/boot/dts/renesas/r8a77970.dtsi ===================================================================
