2009-01-29ARM: OMAP: fix fault in enter_full_retention()Kevin Hilman
In omap24xx_cpu_suspend assembly routine, the r2 register which holds the address of the SDRC_POWER reg is set to zero before the value is written back triggering a fault due to writing to address zero. It's hard to tell where this change was introduced since this file has been moved and merged. While this fix prevents a crash, suspend on my n810 is broken with current kernels. I never come out of suspend. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2008-10-06ARM: OMAP2: Move sleep.S into sleep24xx.STony Lindgren
Some register offsets are different for 242x and 243x. This will allow compiling sleep code for both chips into the same kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the omap24xx_cpu_suspend instead of loading the values since the only. Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL instead of the address as that's what omap24xx_cpu_suspend expects to determine between DDR and SDR. This bug has not been noticed as the boards seem to have DDR instead of SDR. Note that some PM patches are still missing. The PM patches will be added later on once the base files are in sync with linux-omap tree. Signed-off-by: Tony Lindgren <tony@atomide.com>
