Enabling the controller driver on an IMX SoC that doesn't have it is not exactly the end of the world and having to keep adding new IMX SOCs to the list here is annoying. So IMHO, it's ok to make this change even if the controller is allowed on a superset of the SoCs that have it.

There is no separate config option for IMX7S and I don't think it will be ever added. There is however a CONFIG_SOC_IMX6SX. There were attempts to add "depends on"/"selected by" IMX8MQ to various drivers but arm64 maintainers disagreed. This is why this patch fixes the "depends on" list for 6sx pcie by dropping per-SOC logic on 32-bit arm as well. People who want very small kernels for their boards will likely fiddle with their specific defconfig anyway so maybe complex logic in Kconfig is not very helpful. -- Regards, Leonard

I've acked the resend, but that one doesn't show up in patchwork for some reason, so: Acked-by: Lucas Stach <l.stach@pengutronix.de> Regards, Lucas

In theory this driver can be used on imx6sx without enabling support for imx6q or imx7d but the "depends on" condition doesn't allow that. Instead of making the condition even longer just make it depend on "ARCH_MXC || COMPILE_TEST" instead.
