From b9700be51bf00bbe9e1dabcb4838d6aa420192d1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Tue, 5 Jul 2016 06:04:08 +0200 Subject: ARM: dts: imx6sx-sabreauto: Fix misspelled property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In commit 99fc5ba0bfb6 ("ARM: dts: imx6sx: add i.mx6sx sabreauto board support") it should've been enable-sdio-wakeup (not -wakup). But that is now considered a legacy name for wakeup-source, so directly use the new name instead, as done in commit 26cefdd15db1 for the other occurrence.

With this commit, the "standby" mode works well.

So below warning message will be showed during boots up: imx6q_suspend_init: failed to find ocram device! imx6_pm_common_init: No DDR LPM support with suspend -19! Due to lack of ocram device, the suspend mode "mem" which needs ocram to store suspend routine code is invalid. This commit populates platform device before imx6ul_pm_init like other imx6 platforms do, and the suspend mode "mem" can work successfully.
