This is a note to let you know that I have just added a patch titled ARM: dts: Keep G3D regulator always on for exynos5250-arndale to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From e2557aff0a7a110897a28d921e354f673994fe30 Mon Sep 17 00:00:00 2001 From: Tomasz Figa <t.figa@samsung.com> Date: Fri, 14 Feb 2014 07:43:54 +0900 Subject: ARM: dts: Keep G3D regulator always on for exynos5250-arndale commit bfeda827278f09f4db35877e5f1ca9c149ca2890 upstream. Apparently, if G3D regulator is powered off, the SoC cannot enter low power modes and just hangs. This patch fixes this by keeping the regulator always on when the system is running, as suggested by Exynos 4 User's Manual in case of Exynos4210/4x12 SoCs (Exynos5250 UM does not have such note, but observed behavior seems to confirm that it is true for this SoC as well). This fixes an issue preventing Arndale board from entering sleep mode observed since commit 346f372f7b72a0 clk: exynos5250: Add CLK_IGNORE_UNUSED flag for pmu clock that landed in kernel 3.10, which has fixed the clock driver to make the SoC actually try to enter the sleep mode.
