Subject: [PATCH] mfd: rk808: Always use poweroff when requested
Date: Mon,  9 Dec 2019 12:57:46 +0100	[thread overview]
Message-ID: <20191209115746.12953-1-smoch@web.de> (raw)

With the device tree property "rockchip,system-power-controller" we
explicitly request to use this PMIC to power off the system. So always
register our poweroff function, even if some other handler (probably
PSCI poweroff) was registered before.
