+Description
+-----------
+
+The ADT7410 is a temperature sensor with rated temperature range of -55°C to
++150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
+of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
+indicate that a minimum or maximum temperature set point has been exceeded, as
+well as a critical temperature (CT) pin to indicate that the critical
+temperature set point has been exceeded. Both pins can be set up with a common
+hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
+pins can individually set to be active-low or active-high, while the whole
+device can either run in comparator mode or interrupt mode. The ADT7410
+supports continous temperature sampling, as well as sampling one temperature
+value per second or even justget one sample on demand for power saving.
+Besides, it can completely power down its ADC, if power management is
+required.
+
+Configuration Notes
+-------------------
+
+Since the device uses one hysteresis value, which is an offset to minimum,
+maximum and critical temperature, it can only be set for temp#_max_hyst.
+However, temp#_min_hyst and temp#_crit_hyst show their corresponding
+hysteresis.
+The device is set to 16 bit resolution and comparator mode.

-Kernel driver exynos4_tmu
-=================
-
-Supported chips:
-* ARM SAMSUNG EXYNOS4 series of SoC
-  Prefix: 'exynos4-tmu'
-  Datasheet: Not publicly available
-
-Authors: Donggeun Kim <dg77.kim@samsung.com>
-
-Description
------------
-
-This driver allows to read temperature inside SAMSUNG EXYNOS4 series of SoC.
-
-The chip only exposes the measured 8-bit temperature code value
-through a register.
-Temperature can be taken from the temperature code.
-There are three equations converting from temperature to temperature code.
-
-The three equations are:
-  1. Two point trimming
-        Tc = (T - 25) * (TI2 - TI1) / (85 - 25) + TI1
-
-  2. One point trimming
-        Tc = T + TI1 - 25
-
-  3. No trimming
-        Tc = T + 50
-
-  Tc: Temperature code, T: Temperature,
-  TI1: Trimming info for 25 degree Celsius (stored at TRIMINFO register)
-       Temperature code measured at 25 degree Celsius which is unchanged
-  TI2: Trimming info for 85 degree Celsius (stored at TRIMINFO register)
-       Temperature code measured at 85 degree Celsius which is unchanged
-
-TMU(Thermal Management Unit) in EXYNOS4 generates interrupt
-when temperature exceeds pre-defined levels.
-The maximum number of configurable threshold is four.
-The threshold levels are defined as follows:
-  Level_0: current temperature > trigger_level_0 + threshold
-  Level_1: current temperature > trigger_level_1 + threshold
-  Level_2: current temperature > trigger_level_2 + threshold
-  Level_3: current temperature > trigger_level_3 + threshold
-
-  The threshold and each trigger_level are set
-  through the corresponding registers.
-
-When an interrupt occurs, this driver notify user space of
-one of four threshold levels for the interrupt
-through kobject_uevent_env and sysfs_notify functions.
-Although an interrupt condition for level_0 can be set,
-it is not notified to user space through sysfs_notify function.

+-----------
+
+The A/D converters MAX197, and MAX199 are both 8-Channel, Multi-Range, 5V,
+12-Bit DAS with 8+4 Bus Interface and Fault Protection.
+
+The available ranges for the MAX197 are {0,-5V} to 5V, and {0,-10V} to 10V,
+while they are {0,-2V} to 2V, and {0,-4V} to 4V on the MAX199.
+
+Platform data
+-------------
+
+The MAX197 platform data (defined in linux/platform_data/max197.h) should be
+filled with a pointer to a conversion function, defined like:
+
+    int convert(u8 ctrl);
+
+ctrl is the control byte to write to start a new conversion.
+On success, the function must return the 12-bit raw value read from the chip,
+or a negative error code otherwise.
