Reviewing the RB5 schematic its clear that we have missed out on defining both of the power-rails associated with the CSI PHY. Other PHYs such as the UFS, PCIe and USB connect to these rails and define each regulator individually. This means if we were to switch off the other various PHYs which enable these rails, the CAMSS would not appropriately power-on the CSI PHY. Reviewed-by:

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining.

As the possible failure of the vzalloc(), e->encoder_buf might be NULL. Therefore, it should be better to check it in order to guarantee the success of the initialization.
