Okay, so you mux the pins as GPIOs and leave SD_STATUS alone.

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Hi All, This patch series aims to add SD/MMC support for Renesas RZ/V2H(P) SoC. v4->v5 - Since the SDxIOVS and SDxPWEN pins can always be used as GPIO pins on the RZ/V2H(P) SoC dropped adding regulator support. v3->v4 - Dropped 'renesas,sdhi-use-internal-regulator' property - Defined vqmmc-regulator in top level - For special handling of internal regulator now using of_device_is_available() - Fixed comments from Claudiu - Rebased patch on top of https://patchwork.kernel.org/project/linux-renesas-soc/patch/20240626085015.32171-2-wsa+renesas@sang-engineering.com/ v2->v3 - Renamed vqmmc-r9a09g057-regulator object to vqmmc-regulator - Added regulator-compatible property for vqmmc-regulator - Added 'renesas,sdhi-use-internal-regulator' DT property - Included RB tags for patch 2/3 - Moved regulator info to renesas_sdhi_of_data instead of quirks - Added support to configure the init state of regulator - Added function pointers to configure regulator - Added REGULATOR_CHANGE_VOLTAGE mask v1->v2 - Dropped regulator core API changes - Updated DT binding - Now controlling PWEN bit via regulator api v1: https://patchwork.kernel.org/project/linux-renesas-soc/cover/20240605074936.578687-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ Cheers, Prabhakar Lad Prabhakar (3): dt-bindings: mmc: renesas,sdhi: Document RZ/V2H(P) support mmc: tmio: Use MMC core APIs to control the vqmmc regulator mmc: renesas_sdhi: Add RZ/V2H(P) compatible string Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml | 2 ++ drivers/mmc/host/renesas_sdhi_internal_dmac.c | 1 + drivers/mmc/host/tmio_mmc_core.c | 7 +++---- 3 files changed, 6 insertions(+), 4 deletions(-)
