2014-01-06	thermal: remove const flag from .ops of imx thermal	Eduardo Valentin	1	-1/+1
	As per previous changes on thermal framework API, registering a new thermal zone does not require a const thermal zone ops. Thus, this patch removes the flag from imx thermal zone ops.

2014-01-03	thermal: imx: add necessary clk operation	Anson Huang	1	-0/+20
	Thermal sensor needs pll3_usb_otg when measuring temperature, otherwise the temperature read will be incorrect, so need to enable this clk before sensor working, for alarm function, as hardware will take measurement periodically, so we should keep this clk always on once alarm function is enabled.

2014-01-02	thermal: imx_thermal: add module device table	Russell King	1	-0/+1
	Add the module device table declaration so the module can be loaded automatically at boot time. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-01-02	thermal: imx: correct suspend/resume flow	Anson Huang	1	-14/+17
	Fixes regression introduced by: commit 37713a1e8e4c1a1067ad4c99296f78d3c82ed9c4 Author: Philipp Zabel <p.zabel@pengutronix.de> Date: Thu Aug 1 18:33:12 2013 +0200 thermal: imx: implement thermal alarm interrupt handling The commit 37713a1e8e4 makes imx thermal sensor always powered up as alarm function is enabled, but the suspend callback of imx thermal returns success only if thermal sensor is powered down, so it will always returns fail hence break system's suspend, this patch disables imx thermal sensor before suspend and re-enable it after resume.

2013-08-15	thermal: imx: implement thermal alarm interrupt handling	Philipp Zabel	1	-13/+127
	Enable automatic measurements at 10 Hz and use the alarm interrupt to react more quickly to sudden temperature changes above the passive or critical temperature trip points.

2013-08-15	thermal: imx: dynamic passive and SoC specific critical trip points	Philipp Zabel	1	-10/+40
	Set passive and critical trip point values depending on the maximum die temperature stored in the OCOTP fuses. This allows higher trip points for industrial and automotive rated i.MX6 SoCs. Also allow to configure the passive trip point from userspace.

2013-08-13	thermal: add imx thermal driver support	Shawn Guo	1	-0/+397
	This is based on the initial imx thermal work done by Rob Lee <rob.lee@linaro.org> (Not sure if the email address is still valid). Since he is no longer interested in the work and I have rewritten a significant amount of the code, I just took the authorship over from him. It adds the imx thermal support using Temperature Monitor (TEMPMON) block found on some Freescale i.MX SoCs. The driver uses syscon regmap interface to access TEMPMON control registers and calibration data, and supports cpufreq as the cooling device.
