The patch series for the on die temperature sensor driver.
The patch set has the device file, omap4 on die temperature sensor
hwmon driver. hwmod, clk support. The patch set compiles
on top of LO tree Master branch.
This patch series is tested for boot-up on OMAP4460. The temperature
reading and the interrupts generation on crossing the temperature
thresholds also tested.
V4:
(1) Reordered the probe sequence in the driver.
(2) Introduced iounmap in the driver in the error paths and remove function.
(3) In case of user/application programming thresholds violating t_hot > t_cold
condition, the driver automatically changes the other threshold to adhere
to the condition.
V3:
(1) Fixed comments on the return values in the device file
(2) Removed unnecessary error messages.
(3) Redundant braces removed.
(4) Implemented binary search in place of linear for temp to adc conversion.
(5) Wrong usage of EINVAL corrected.
V2:
(1) Fixed comments on return values in the driver.
(2) Moved the TEMPSOFF setting code to the activate/deactivate hooks.
(3) Used idr to pass for the device id.
