[5/8] platform: mellanox: select REGMAP instead of depending on it
Commit Message
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".
For NVSW_SN2201, select REGMAP_I2C instead of depending on it.
Fixes: c6acad68eb2d ("platform/mellanox: mlxreg-hotplug: Modify to use a regmap interface")
Fixes: 5ec4a8ace06c ("platform/mellanox: Introduce support for Mellanox register access driver")
Fixes: 62f9529b8d5c ("platform/mellanox: mlxreg-lc: Add initial support for Nvidia line card devices")
Fixes: 662f24826f95 ("platform/mellanox: Add support for new SN2201 system")
