|
||||
Subject: regmap: allow to define reg_update_bits for no bus configuration
|
||||
|
||||
Some device requires a special handling for reg_update_bits and can't use
|
||||
the normal regmap read write logic. An example is when locking is
|
||||
handled by the device and rmw operations requires to do atomic operations.
|
||||
Allow to declare a dedicated function in regmap_config for
|
||||
reg_update_bits in no bus configuration.
