[PATCH v4 09/17] media: qcom: camss: Remove special case for VFE get/put

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

 



>From sdm845 onwards we need to ensure the VFE is powered on prior to
switching on the CSID.

Currently the code tests for sdm845, sm8250 and then does get/set. This is
not extensible and it turns out is not necessary either since vfe_get and
vfe_set reference count.

Remove the over-conservative SoC version check.
