Merge tag 'omap-for-v4.17/am-pm-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
Pull "Add am335x and am437x PM code for v4.17" from Tony Lindgren: This series of changes from Dave Gerlach adds the PM related code to allow low-power suspend states. The code consists of the SoC specific assembly code and a related PM driver. * tag 'omap-for-v4.17/am-pm-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: soc: ti: Add pm33xx driver for basic suspend support ARM: OMAP2+: pm33xx-core: Add platform code needed for PM ARM: OMAP2+: Introduce low-level suspend code for AM43XX ARM: OMAP2+: Introduce low-level suspend code for AM33XX
