[PATCH 0/2] pmdomain: imx93: Fix shared MIPI PHY resource management

> Subject: [PATCH 0/2] pmdomain: imx93: Fix shared MIPI PHY resource
> management
> 
> The i.MX93 MIPI DSI and CSI domains share control bits for clock and
> reset in the media block controller. This creates a resource conflict
> where one domain can inadvertently disable shared resources while
> the other domain is still active, leading to system instability.
> 
> This series fixes the issue by introducing a dedicated MIPI PHY power
> domain that owns the shared clock and reset control bits. The DSI and
> CSI domains are then made subdomains of this PHY domain, ensuring
> proper reference counting and preventing premature resource
> shutdown.
> 
> Tested on i.MX93 EVK with concurrent DSI and CSI operations.
