From f9800dde34e678d7ed1de9e95b4b65a257fd0f93 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Wed, 2 Feb 2022 13:23:38 -0800 Subject: [PATCH] arm64: dts: qcom: sc7280: Clean up sdc1 / sdc2 pinctrl This patch makes a few improvements to the way that sdc1 / sdc2 pinctrl is specified on sc7280: 1. There's no reason to "group" the sdc pins into one overarching node and there's a downside: we have to replicate the hierarchy in the board device tree files. Let's clean this up. 2. There's really not a lot of reason not to list the "pinctrl" for sdc1 (eMMC) in the SoC dtsi file. These aren't GPIO pins and everyone's going to specify the same pins. 3. Even though it's likely that boards will need to override pinctrl for sdc2 (SD card) to add the card detect GPIO, we can be symmetric and add it to the SoC dsti file. 4. Let's get rid of the word "on" from the normal config and add a "sleep" suffix to the sleep config. This looks cleaner to me. This is intended to be a no-op change but it could plausibly change behavior depending on how the pinctrl code parses things. One thing to note is that "SD card detect" is explicitly listed now as keeping its pull enabled in sleep since we still want to detect card insertions even if the controller is suspended (because no card is inserted). The pinctrl framework likely did this anyway, but it's nice to see it explicit.
