From: Daniel Schultz d.schultz@phytec.de

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.

Fixes: 9d6105e19f61 ("mfd: rk808: Fix up the chip id get failed") Cc: stable@vger.kernel.org Cc: Elaine Zhang zhangqing@rock-chips.com Cc: Joseph Chen chenjh@rock-chips.com Signed-off-by: Daniel Schultz d.schultz@phytec.de Acked-by: Lee Jones lee.jones@linaro.org [added Fixes and cc-stable] Signed-off-by: Heiko Stuebner heiko@sntech.de --- The original patch from Feburary 2018 got an Ack but never reached the mfd-tree, so I ran into that problem this weekend as well. So it would be really cool if this could be applied as fix :-) .
