arm64: dts: rockchip: Pull up wlan wake# on Gru-Bob
[ Upstream commit e5467359 ] The Gru-Bob board does not have a pull-up resistor on its WLAN_HOST_WAKE# pin, but Kevin does. The production/vendor kernel specified the pin configuration correctly as a pull-up, but this didn't get ported correctly to upstream. This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent wakeup behavior. Note that bt_host_wake_l has a similar dynamic, but apparently the upstream choice was to redundantly configure both internal and external pull-up on Kevin (see the "Kevin has an external pull up" comment in rk3399-gru.dtsi). This doesn't cause any functional problem, although it's perhaps wasteful. Fixes: 8559bbee ("arm64: dts: rockchip: add Google Bob") Signed-off-by:Brian Norris <briannorris@chromium.org> Reviewed-by:
