Subject: [PATCH v1] ARM: dts: aspeed: mtjade: Add some gpios
Date: Fri, 17 Sep 2021 15:29:45 +0700 [thread overview]
Message-ID: <20210917082945.19111-1-quan@os.amperecomputing.com> (raw)
Add S0_SCP_AUTH_FAIL, S1_SCP_AUTH_FAIL gpios to indicates firmware
authentication fail on each socket.
Add gpio RTC_BAT_SEN_EN to enable RTC battery adc sensor.
Add BMC_I2C4_O_EN gpio to go high at boot to enable access to I2C4 bus.
