From d7e2ee257038baeb03baef602500368a51ee9eef Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 11 Apr 2016 13:51:03 +0200 Subject: [PATCH] spi: let SPI masters ignore their children for PM Let all SPI masters ignore their children: when it comes to power management: SPI children have no business doing keeping their parents awake: they are completely autonomous devices that just use their parent to talk, and the latter usecase must be power managed by the host itself on a per-message basis.
