The cros_ec driver currently assumes that cros-ec-spi compatible device nodes are a wakeup-source even though the wakeup-source property is not defined. Some Chromebooks use a separate wake pin, while others overload the interrupt for wake and IO. With the current assumption, spurious wakes can occur on systems that use a separate wake pin. It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source. -Commit-changes: 3 -Update commit message to provide details of the motivation behind the change Signed-off-by: Mark Hasemeyer <markhas@chromium.org> --- (no changes since v2) Changes in v2: -Split by arch/soc arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi | 1 + arch/arm64/boot/dts/qcom/sc7280-idp-ec-h1.dtsi | 1 + 2 files changed, 2 insertions(+)
