Subject: [PATCH backport 5.10 05/10] i2c: mlxcpld: Allow to configure base
|
||
|
|
address of register space
|
||
|
|
|
||
|
|
Allow to use configured base address.
|
||
|
|
|
||
|
|
Currently driver uses constant base address of register space.
|
||
|
|
On new systems this base address could be different, thus it could be
|
||
|
|
passed to the driver through platform data.
