Could you please move the switch to the previous patch? Then it would
be more obvious that you are just adding the SPMI_VIB_GEN2 here.

Other than that LGTM.

Sure, I can move the switch to the previous refactoring patch.

Actually, the idea of having a const "reg" or "chip", etc. structure is
to avoid this kind of runtime checks based on hardware type and instead
use common computation. I believe you need to move mask and shift into
the chip-specific structure and avoid defining hw_type.

Thanks.

Hi Dmitry,

The v7 changes have been pending for a while, I am not sure if you are still insist on this. As I explained, I actually did it this way in v2 and it got updated to this by following other comments.

Can you respond and tell me if you prefer changes similar to v2? I can update and push v8 by following your suggestion.

v7: https://lore.kernel.org/linux-arm-msm/20231108-pm8xxx-vibrator-v7-0-632c731d25a8@xxxxxxxxxxx/

v2: https://lore.kernel.org/linux-arm-msm/20230718062639.2339589-3-quic_fenglinw@xxxxxxxxxxx/

Thanks
