Add a resource managed devm_iio_trigger_alloc()/devm_iio_triger_free() to automatically clean up triggers allocated by IIO drivers, thus leading to simplified IIO drivers code. Signed-off-by:

The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC, known also as Phoenix and PhoenixLite. The TWL6030 and TWL6032 have GPADC with 17 and 19 channels respectively. Some channels have current source and are used for measuring voltage drop on resistive load for detecting battery ID resistance, or measuring voltage drop on NTC resistors for external temperature measurements. Some channels measure voltage, (i.e. battery voltage), and have voltage dividers, thus, capable to scale voltage. Some channels are dedicated for measuring die temperature. Some channels are calibrated in 2 points, having offsets from ideal values kept in trim registers. This is used to correct measurements. The differences between GPADC in TWL6030 and TWL6032: - 10 bit vs 12 bit ADC; - 17 vs 19 channels; - channels have different purpose(i.e. battery voltage channel 8 vs channel 18); - trim values are interpreted differently. Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K, Girish S Ghongdemath. Signed-off-by:

The LRADC virtual channels have an 18 bit field to store the sum of up to 2^5 accumulated samples. The read_raw function however only operates over a single sample (12 bit resolution). In order to use this field for scaling operations, we need it to be the exact resolution value of the LRADC. Besides, the driver was using an 18 bit mask (LRADC_CH_VALUE_MASK) to report touch coordinates to userland. A 12 bit mask should be used instead or else the touch libraries will expect a coordinates range between 0 and 0x3ffff (18 bits), instead of between 0 and 0xfff (12 bits). Signed-off-by:

the TI TMP006 is a non-contact temperature sensor with I2C interface; it measures the surface temperature of a distance object using a thermopile to absorb IR energy emitted from the object the sensor has two channels: IR sensor voltage (16-bit) and reference temperature of the chip (14-bit); datasheet is here: http://www.ti.com/lit/ds/symlink/tmp006.pdf v2 (thanks to Grygorii Strashko, Lars-Peter Clausen, Jonathan Cameron for review comments): * power down device on driver remove * use sign_extend32() * style cleanup * add comments what channel raw LSBs mean * spelling of thermopile Signed-off-by:

Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be used by default to not leak file descriptor across exec(). Instead of macro get_unused_fd(), functions anon_inode_getfd() or get_unused_fd_flags() should be used with flags given by userspace. If not possible, flags should be set to O_CLOEXEC to provide userspace with a default safe behavor. In a further patch, get_unused_fd() will be removed so that new code start using anon_inode_getfd() or get_unused_fd_flags() with correct flags. This patch replaces calls to get_unused_fd() with call to get_unused_fd_flags(O_CLOEXEC) following advice from Erik Gilling. Signed-off-by:

This patch replace some magic numbers. I believe it makes the driver more readable. The magic number 0x26 is the XO system embedded controller (EC) command 'DCON power enable/disable'. Number 0x41, and 0x42 are special memory controller settings register. The 0x41 initialize bit sequence 0x101 means: enable memory power down function and special SDRAM clock delay for synchronize SDRAM output and clock signal. The 0x42 initialize squence 0x101 is wrong. According to the specification Bit 8 is reserved, thus not in use. I removed it. Signed-off-by:

This patch removes the dgnc_proc.c and dgnc_proc.h files and all references to proc functions in dgnc_driver.c. This also removes proc.h from the include headers in driver.c, mgmt.c and sysfs.c and proc.o from the Makefile. Drivers now use sysfs instead of proc. Signed-off-by:

This patch separates success & failure block along with fixing following issues:- 1. The way oz_hcd_pd_arrived() looks now it's easy to think we free "ep" but actually we do this spaghetti thing of setting it to NULL on success. 2. It is hard to read it because there are unlocks scattered throughout. 3. Currently we set "ep" to NULL on the success path and then test it and or free it. In current code you have to scroll to the start of the function to read code.
