From a871be6b8eee13a35a3e8e56c62770ef17ee9220 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Thu, 16 Apr 2020 10:58:21 +0200 Subject: cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver The Qualcomm SPM cpuidle driver seems to be the last driver still using the generic ARM CPUidle infrastructure. Converting it actually allows us to simplify the driver, and we end up being able to remove more lines than adding new ones: - We can parse the CPUidle states in the device tree directly with dt_idle_states (and don't need to duplicate that functionality into the spm driver). - Each "saw" device managed by the SPM driver now directly registers its own cpuidle driver, removing the need for any global (per cpu) state. The device tree binding is the same, so the driver stays compatible with all old device trees.
