From 0e70f466fb910ae54c4c71243b99385129e93feb Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Fri, 26 Aug 2016 16:21:16 -0700 Subject: thermal: Enhance thermal_zone_device_update for events Added one additional parameter to thermal_zone_device_update() to provide caller with an optional capability to specify reason. Currently this event is used by user space governor to trigger different processing based on event code. Also it saves an additional call to read temperature when the event is received. The following events are cuurently defined: - Unspecified event - New temperature sample - Trip point violated - Trip point changed - thermal device up and down - thermal device power capability changed Signed-off-by: Srinivas Pandruvada Signed-off-by: Zhang Rui --- drivers/thermal/rockchip_thermal.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/thermal/rockchip_thermal.c') diff --git a/drivers/thermal/rockchip_thermal.c b/drivers/thermal/rockchip_thermal.c index 1f165c990c85..e227a9f0acf7 100644 --- a/drivers/thermal/rockchip_thermal.c +++ b/drivers/thermal/rockchip_thermal.c @@ -873,7 +873,8 @@ static irqreturn_t rockchip_thermal_alarm_irq_thread(int irq, void *dev) thermal->chip->irq_ack(thermal->regs); for (i = 0; i < thermal->chip->chn_num; i++) - thermal_zone_device_update(thermal->sensors[i].tzd); + thermal_zone_device_update(thermal->sensors[i].tzd, + THERMAL_EVENT_UNSPECIFIED); return IRQ_HANDLED; } -- cgit v1.2.3-59-g8ed1b
