From 4147ffa3d96dde43bd4f3607db75f261fafaade2 Mon Sep 17 00:00:00 2001 From: Wangao Wang Date: Fri, 29 May 2026 15:34:59 +0800 Subject: [PATCH] media: iris: Add hardware power on/off ops for X1P42100 On X1P42100 the Iris block has an extra BSE clock. Wire this clock into the power on/off sequence. The BSE clock is used to drive the Bin Stream Engine, which is a sub-block of the video codec hardware responsible for bitstream-level processing. It is required to be enabled separately from the core clock to ensure proper codec operation.
