[PATCH v6 07/23] media: rzg2l-cru: Remove `channel` member from `struct rzg2l_cru_csi`
Posted by Prabhakar 1 month, 1 week ago
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Remove the CSI virtual channel number from `struct rzg2l_cru_csi`.
Instead, pass the CSI virtual channel number as an argument to
`rzg2l_cru_csi2_setup()`.
