Add device nodes for the General Purpose Input/Output (GPIO) blocks on the Renesas R-Car S4-8 (R8A779F0) SoC. Note that GPIO blocks 4-7 are not added, as they can only be accessed from the Control Domain. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Tested with i2c-gpio, by reading the contents from the I2C EEPROMs connected to I2C4 (GP1_[89]) on the Spider development board. Note that this requires manual setting of MOD_SEL1 to zero in U-Boot, as the pin control driver does not handle this special case yet. v2: - Drop gpio4-7], - Drop RFC, - Split series in DT bindings+driver series and DTS patch. --- arch/arm64/boot/dts/renesas/r8a779f0.dtsi | 60 +++++++++++++++++++++++ 1 file changed, 60 insertions(+)
