AM654 baseboard has two TCA9554 I/O expander on the WKUP_I2C0 bus. The expander at address 0x38 is used to detect daughter cards. Add a node for this I/O expander. Signed-off-by: Ravi Gunasekaran <r-gunasekaran@xxxxxx> --- Changes from v1: --------------- * Moved the expander node @38 to appear before the one at address 39. * Removed the label pca9554_1 for the node as it is not used. v1: https://lore.kernel.org/all/20230919050340.16156-1-r-gunasekaran@xxxxxx/ arch/arm64/boot/dts/ti/k3-am654-base-board.dts | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am654-base-board.dts b/arch/arm64/boot/dts/ti/k3-am654-base-board.dts index f5c26e9fba98..1637ec5ab5ed 100644 --- a/arch/arm64/boot/dts/ti/k3-am654-base-board.dts +++ b/arch/arm64/boot/dts/ti/k3-am654-base-board.dts @@ -369,6 +369,13 @@ ti,enable-vout-discharge; }; + gpio@38 { + compatible = "nxp,pca9554"; + reg = <0x38>; + gpio-controller; + #gpio-cells = <2>; + }; + pca9554: gpio@39 { compatible = "nxp,pca9554"; reg = <0x39>; base-commit: dfa449a58323de195773cf928d99db4130702bf7 -- 2.17.1
