2014-07-23ARM: dts: Fix wrong compatible string for Exynos3250 ADCiio-for-3.17dChanwoo Choi
This patchset fix wrong compatible string for Exynos3250 ADC. Exynos3250 SoC need to control only special clock for ADC. Exynos SoC except for Exynos3250 has not included special clock for ADC. The exynos ADC driver can control special clock if compatible string is 'exynos3250-adc-v2'.

2014-07-23iio: devicetree: Add DT binding documentation for Exynos3250 ADCChanwoo Choi

2014-07-23iio: adc: exynos_adc: Control special clock of ADC to support Exynos3250 ADCChanwoo Choi
This patch control special clock for ADC in Exynos series's FSYS block. If special clock of ADC is registerd on clock list of common clk framework, Exynos ADC drvier have to control this clock. Exynos3250/Exynos4/Exynos5 has 'adc' clock as following: - 'adc' clock: bus clock for ADC Exynos3250 has additional 'sclk_adc' clock as following: - 'sclk_adc' clock: special clock for ADC which provide clock to internal ADC Exynos 4210/4212/4412 and Exynos5250/5420 has not included 'sclk_adc' clock in FSYS_BLK. But, Exynos3250 based on Cortex-A7 has only included 'sclk_adc' clock in FSYS_BLK.

Assigning indio_dev->trig is not a good idea, as this can result in wrong reference count for trigger device. If assigned, it is better to increment reference counter by calling iio_trigger_get.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 3rd round of IIO new drivers, cleanups and functionality for the 3.17 cycle. New drivers * isl29125 digital color light sensor driver * TAOS/AMS tcs3414 digital color sensor Staging graduation * ad7291 ADC driver. New functionality * st_sensors - device tree support and bindings * mma8452 - device tree support Cleanups * Drop redundant variables in a number of drivers. * Reorder a structure definition to ealy wiht a warning about static not being at the beginning in the hid-sensors driver. * Switch a few more drivers away from using explicit sampling_frequency attribute to providing this through the core. * Make hid_sensor_get_reporting_interval static as only used within a single file. * Drop a redundant check for negative values in an unsigned variable from ad9832 * Drop some duplicate case labels in the event monitor example code. * Use devm_ioremap_resource to simplify error handling. * Use devm_kzalloc within the blackfin timer driver to simplify error handling and removal. * A number of cleanups of the ad7291 from Hartmut Knaack in response to a patch moving it out of staging. * Core support for the period info element about events. It has been in the abi for a while, but not added until now to the newer handling of information related to events. * Add HAS_IOMEM dependency to mxs_lradc to avoid build issues when testing enabled.
