[RFC PATCH 1/3] gpio: pca953x: Replace chip type flags with a type enum

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The driver supports 8 chip types. The chip type is encoded in
driver_data so that different chip types can be handled appropriately.

Encoding the type information in separate bit flags was not too
straightforward, and it didn't make it possible to encode 8 chip
types.

Replace bit flags with a pca953x_chip_type enum. Encode this enum in
driver_data as a number. Add missing chip types based on chip functions
and register layout.
