Subject: [PATCH] mfd: rk808: Fix RK818 ID template
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.

RK809 support") and queued for 4.19 and 4.14.
