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. Fixes: 9d6105e19f61 ("mfd: rk808: Fix up the chip id get failed") Cc: stable@xxxxxxxxxxxxxxx Cc: Elaine Zhang <zhangqing@xxxxxxxxxxxxxx> Cc: Joseph Chen <chenjh@xxxxxxxxxxxxxx> Signed-off-by: Daniel Schultz <d.schultz@xxxxxxxxx> Acked-by: Lee Jones <lee.jones@xxxxxxxxxx> [added Fixes and cc-stable] Signed-off-by: Heiko Stuebner <heiko@xxxxxxxxx> --- 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 :-) . include/linux/mfd/rk808.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/mfd/rk808.h b/include/linux/mfd/rk808.h index d3156594674c..338e0f6e2226 100644 --- a/include/linux/mfd/rk808.h +++ b/include/linux/mfd/rk808.h @@ -443,7 +443,7 @@ enum { enum { RK805_ID = 0x8050, RK808_ID = 0x0000, - RK818_ID = 0x8181, + RK818_ID = 0x8180, }; struct rk808 { -- 2.20.1
