Subject: ENGR00225981-7 csi: Unify the api set_mclk_rate
X-Git-Tag: v3.0.35-fsl~399
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=76aba2d0694b71195e194bdbf3d9e71c631272f0;p=karo-tx-linux.git

ENGR00225981-7 csi: Unify the api set_mclk_rate

For CSI on MX6SL, there's only 1 CSI and hence no need to change csi souce.
We add this parameter just for compatibility.

Adjust the called api in related camera drivers.
