2013-02-06thermal: rcar: use mutex lock instead of spin lockKuninori Morimoto1-23/+7
Current R-Car thermal driver is using spin lock for each registers read/write, but it is pointless lock. This lock is required while reading temperature, but it needs long wait (= 300ms). So, this patch used mutex lock while reading temperature, instead of spin lock for each registers.

2013-02-06thermal: rcar: enable CPCTL to use hardware TSC decidingKuninori Morimoto1-65/+26
If CPCTL was 1 on R-Car thermal, the thermal comparator offset is automatically decided by hardware. And this CPCTL is the conditions which validate interrupt. This patch enabled CPCTL.

2013-01-04thermal: rcar: add .get_trip_type/temp and .notify supportkuninori.morimoto.gx@renesas.com1-3/+65
This patch adds .get_trip_type(), .get_trip_temp(), and .notify() on rcar_thermal_zone_ops. Driver will try platform power OFF if it reached to critical temperature. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
