Subject: [PATCH 038/102] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135()
|
|
and pwrap_is_mt8173()
|
|
|
|
With more SoCs being added the list of helper functions like these would
|
|
grow. To mitigate this problem we remove the existing helpers and change
|
|
the code to test against the pmic type stored inside the pmic specific
|
|
datastructure that our context structure points at. There is one usage of
|
|
pwrap_is_mt8135() that is ambiguous as the test should not be dependent on
|
|
mt8135, but rather on the existence of a bridge. Add a new element to
|
|
pmic_wrapper_type to indicate if a bridge is present and use this where
|
|
appropriate.
|
