From: Tony Lindgren Date: Mon, 11 Sep 2023 03:58:28 +0000 (+0300) Subject: ARM: dts: motorola-mapphone: Add mdm6600 sleep pins X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a36f8ac61b043d387e6f71d4f537971f603e8a5a;p=linux.git 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.
