[PATCH 6.8 258/715] arm64: dts: renesas: rzg3s-smarc-som: Guard Ethernet IRQ GPIO hogs

[Sasha Levin]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

[ Upstream commit 150d81f7a260f36c118cbec253fdd493c671dc29 ]

Ethernet IRQ GPIOs are marked as GPIO hogs.  Thus, these GPIOs are
requested at probe time without considering if there are other
peripherals that need them.  The Ethernet IRQ GPIOs are shared with
SDHI2.  Selection between Ethernet and SDHI2 is done through a hardware
switch.  To avoid scenarios where one wants to boot with SDHI2 support
and some SDHI pins are not propertly configured because of the GPIO
hogs, guard the Ethernet IRQ GPIO hogs with the proper build flag.

Fixes: 932ff0c802c6 ("arm64: dts: renesas: rzg3s-smarc-som: Enable the Ethernet interfaces")
