From 070ead4d4aaf30f5c6017054b822c3c6d649b071 Mon Sep 17 00:00:00 2001 From: Rui Salvaterra Date: Tue, 30 Mar 2021 23:59:50 +0100 Subject: [PATCH] ramips/mt7621: enable support for cpuidle MIPS Coherent Processor Systems (CPS), which include the MT7621 SoC, support deep sleep idle states and have a specific cpuidle driver for them. Enable support for it, while also switching from constant timer ticks to the idle dynticks model, with the TEO governor. Run-tested on a Redmi AC2100.
