Subject: Re: [PATCH] PCI: rcar-host: Validate IO/MEM resource count in DT ranges property
Date: Sat, 03 Oct 2026 07:42:51 +0000 [thread overview]

> The R-Car Gen3 PCIEC controller supports up to 4 memory area mappings.
> Count the IO and MEM ranges described in DT 'ranges' property of the
> controller DT node, and in case there are more than 4, refuse to probe
> the controller driver, because such DT does not describe valid hardware
> configuration. Do the IO and MEM counting early to avoid controller
> configuration rollback in case of failure.
