For devices in the RZ/G2L family, we have so far relied on U-Boot correctly configuring the Ethernet interfaces in RGMII mode with PVDD=1.8V before the kernel is booted. Instead, the required configuration should be described in the device tree and activated within the pinctrl driver. Changes v2->v3: * Picked up Linus W's Acked-by tags & Geert's Reviewed-by tags. * Renamed rzg3s oen functions to match the callback names. * Check pin caps before calling oen_{read,write}() so we can drop the caps argument to those functions. * Simplify arguments to rzg{2l,3s}_pin_to_oen_bit() and decode required variables inside this function. * Check for dedicated pin before calling RZG2L_PIN_ID_TO_{PORT,PIN}() in rzg3s_pin_to_oen_bit(). Changes v1->v2: * Rebased on next-20240611. * Changed the approach taken in the pinctrl patches to be compatible with changes made by Prabhakar for RZ/V2H support. I haven't picked up Reviewed-by tags on these patches as they've changed a lot. * Clarified that patch 6/9 also affects RZ/Five. * No major changes to the dts patches so I've picked up Geert's Reviewed-by tags for these.
