Revision fbaff059c29e4002d8cf5dbb71ad812c1f3d976e authored by Olof Johansson on 29 October 2016, 18:08:50 UTC, committed by Olof Johansson on 29 October 2016, 18:08:50 UTC
The i.MX fixes for 4.9:
 - A couple of patches from Fabio to fix the GPC power domain regression
   which is caused by PM Domain core change 0159ec670763dd
   ("PM / Domains: Verify the PM domain is present when adding a
   provider"), and a related kernel crash seen with multi_v7_defconfig
   build.
 - Correct the PHY ID mask for AR8031 to match phy driver code.
 - Apply new added timer erratum A008585 for LS1043A and LS2080A SoC.
 - Correct vf610 global timer IRQ flag to avoid warning from gic driver
   after commit 992345a58e0c ("irqchip/gic: WARN if setting the
   interrupt type for a PPI fails").
