From a36f8ac61b043d387e6f71d4f537971f603e8a5a Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 11 Sep 2023 06:58:28 +0300 Subject: [PATCH] ARM: dts: motorola-mapphone: Add mdm6600 sleep pins The sleep pins never got added earlier probably because the driver was not behaving correctly with the sleep pins. We need the sleep pins to prevent the modem from waking up on it's own if the reset pin glitches in deeper SoC idle states.
