ARM: tango: add Suspend-to-RAM support

2016-07-07T14:09:30+00:00

Ask firmware to put RAM in self-refresh mode and power system down. echo mem > /sys/power/state See Documentation/power/states.txt Signed-off-by: Marc Gonzalez Signed-off-by: Arnd Bergmann

ARM: tango: fix CONFIG_HOTPLUG_CPU=n build

2016-07-07T04:44:58+00:00

Building with CONFIG_HOTPLUG_CPU disabled fails for mach-tango: include/linux/stddef.h:7:14: error: excess elements in struct initializer [-Werror] #define NULL ((void *)0) arch/arm/mach-tango/platsmp.c:48:15: note: in expansion of macro 'tango_cpu_kill' .cpu_kill = tango_cpu_kill, the problem as that the .cpu_kill and .cpu_die struct members are unavailable and we must not try to assign them in this configuration. Hiding the two (as all other platforms do too) lets us get rid of the #else clause as well. Signed-off-by: Arnd Bergmann Signed-off-by: Olof Johansson

ARM: tango: use "depends on" instead of "if" after prompt

2016-02-01T20:18:49+00:00

This platform was recently added, so missed the global fixup by commit e32465429490 ("ARM: use "depends on" for SoC configs instead of "if" after prompt"). Fix it now. Signed-off-by: Masahiro Yamada Acked-by: Marc Gonzalez Signed-off-by: Olof Johansson

ARM: tango: use const and __initconst for smp_operations

2016-02-01T20:18:23+00:00

This newly added code missed the global fixup by commit 75305275a721 ("ARM: use const and __initconst for smp_operations"). So fix it now. Signed-off-by: Masahiro Yamada Acked-by: Marc Gonzalez Signed-off-by: Olof Johansson

ARM: tango: Fix UP build issues

2016-01-07T05:33:41+00:00

Move SMP setup to platsmp.c for consistency with other platforms. Signed-off-by: Marc Gonzalez Signed-off-by: Olof Johansson

ARM: tango: pass ARM arch level for smc.S

2015-12-31T16:48:32+00:00

allmodconfig is broken by the addition of the -mcpu=cortex-a9 flag for smc.S: arch/arm/mach-tango/smc.S:1:0: warning: switch -mcpu=cortex-a9 conflicts with -march=armv6k switch This sets the flag in the same way that all other platforms do, to fix the compile error. Signed-off-by: Arnd Bergmann

ARM: tango4: Initial platform support

2015-12-22T23:10:31+00:00

Support Sigma Designs ARM-based (specifically, Cortex-A9 MPCore r3p0) Tango4 "Secure Media Processor" platforms: smp8756, smp8758, smp8759 (8756 is single-core, the latter are dual-core). Note: 8758 vs 8759: same chip, different package. Support for older MIPS-based platforms can be found elsewhere: https://github.com/mansr/linux-tangox Signed-off-by: Marc Gonzalez Reviewed-by: Kevin Hilman Signed-off-by: Olof Johansson
