Enable the I2C0 bus on the White Hawk CPU board, and describe the I2C EEPROMs present on the White Hawk CPU and BreakOut boards. Based on a larger patch in the BSP by Takeshi Kihara. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Changes compared to the BSP: - Add missing BreakOut board EEPROM. --- .../dts/renesas/r8a779g0-white-hawk-cpu.dtsi | 20 +++++++++++++++++++ .../boot/dts/renesas/r8a779g0-white-hawk.dts | 9 +++++++++ 2 files changed, 29 insertions(+)
