From adc91db0e6f83653da06066bc60633d7a437bcbd Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Wed, 8 May 2019 11:11:45 +0530 Subject: [PATCH] rockchip: dts: rk3399: nanopi4: Use CD pin as RK_FUNC_1 Attaching GPIO functionality to SDMMC0_DET pin (which does in Linux base dts) make dwmmc driver "fail to detect the card". Card did not respond to voltage select! It may be because the existing driver can't support gpio card detection. So, change the pinctrl functionality from RK_FUNC_GPIO to RK_FUNC_1 like other rk3399 dts does via sdmmc_cd pin.
