From 6d523c00412b5c6bc2e3020bbc1b48abd8b68804 Mon Sep 17 00:00:00 2001 From: Christian Speich Date: Mon, 22 Apr 2024 17:36:34 +0000 Subject: [PATCH 1057/1085] dts: overlay: ov5647: Specify clock-noncontinuous on CSI endpoint The OV5647 declares that it wants a non-continuous clock in its endpoint configuration. However, it does not expose this information via get_mbus_config. Even if it would implement get_mbus_config the bcm2835-unicam driver would not evaluate the flags field of it. By also specifying clock-noncontinuous on the CSI endpoint itself, the CSI driver properly picks up the requests and enables the non-continuous clock mode.
