2015-08-03ARM: migrate to common PSCI client codeMark Rutland1-7/+9
Now that the common PSCI client code has been factored out to drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code over to it. This results in a moderate reduction of duplicated lines, and will prevent further duplication as the PSCI client code is updated for PSCI 1.0 and beyond. The two legacy platform users of the PSCI invocation code are updated to account for interface changes. In both cases the power state parameter (which is constant) is now generated using macros, so that the pack/unpack logic can be killed in preparation for PSCI 1.0 power state changes.

2013-10-01ARM: highbank: adapt to use ARM PSCI callsRob Herring1-18/+9
This adapts highbank to use psci for smp_ops and the cpu_suspend function for suspend/resume. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2012-10-31ARM: highbank: abstract out SCU usageRob Herring1-3/+0
In preparation for A15 support on ECX-2000, the direct calls to SCU registers must be conditional. The SCU power mode register is replaced by a custom register on ECX-2000. Rather than read the number of cores from the SCU, just hardcode it to 4. This removes one use of SCU and removes the need for the SCU to be statically mapped. The cpu initialization will ultimately come from DT. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
2012-09-20ARM: highbank: call highbank_pm_init from .init_machineRob Herring1-3/+1
Being a module_init call, highbank_pm_init will cause problem with multi-platform build running on other platforms. Call it from .init_machine instead. Reported-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Olof Johansson <olof@lixom.net>
