From 721e0497172f0fa661eed2d63367cddf479f35e8 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 7 Aug 2016 21:02:38 +0200 Subject: mmc: pwrseq-simple: Add an optional post-power-on-delay Some devices need a while to boot their firmware after providing clks / de-asserting resets before they are ready to receive sdio commands. This commits adds a post-power-on-delay-ms devicetree property to mmc-pwrseq-simple for use with such devices.
