Subject: [PATCH v2 0/2] mmc: host: renesas_sdhi_core: support configuring an optional sdio mux
Date: Mon, 01 Dec 2025 13:31:09 +0100 [thread overview]
Message-ID: <20251201-rz-sdio-mux-v2-0-bcb581b88dd7@solid-run.com> (raw)
Some Renesas SoC based boards mux SD and eMMC on a single sdio
controller, exposing user control by dip switch and software control by
gpio.
Purpose is to simplify development and provisioning by selecting boot
media at power-on, and again before starting linux.
Add binding and driver support for linking a (gpio) mux to renesas sdio
controller.
