From ad4a38d2187720a3d1442d693c99675ccd955f32 Mon Sep 17 00:00:00 2001 From: Sylvain Rochet Date: Thu, 5 Feb 2015 14:00:37 +0800 Subject: [PATCH 01/31] pm: at91: pm_slowclock: fix suspend/resume hang up in timeouts Removed timeout on XTAL, PLL lock and Master Clock Ready, hang if something went wrong instead of continuing in unknown condition. There is not much we can do if a PLL lock never ends, we are running in SRAM and we will not be able to connect back the sdram or ddram in order to be able to fire up a message or just panic. As a bonus, not decounting the timeout register in slow clock mode reduce cumulated suspend time and resume time from ~17ms to ~15ms.

The DDRSDR controller fails miserably to put LPDDR1 memories in self-refresh. Force the controller to think it has DDR2 memories during the self-refresh period, as the DDR2 self-refresh spec is equivalent to LPDDR1, and is correctly implemented in the controller. Assume that the second controller has the same fault, but that is untested.
