[PATCH 1/4] mfd: rk808: fix rk818 ID template

From: Heiko Stuebner
Date: Tue Sep 17 2019 - 04:13:35 EST


From: Daniel Schultz <d.schultz@xxxxxxxxx>

The Rockchip PMIC driver can automatically detect connected component
versions by reading the ID_MSB and ID_LSB registers. The probe function
will always fail with RK818 PMICs because the ID_MSK is 0xFFF0 and the
RK818 template ID is 0x8181.

This patch changes this value to 0x8180.
