This series includes three patches: 1.Change the device tree binding documentation. 2.Add auxadc driver based on linux iio. 3.Add auxadc nodes in the mediatek MT2701 dtsi file. Changes in patch v4: 1).Change the file name 'mt65xx_auxdc.txt' to 'mt6577_auxdc.txt'. 2).Remove 'break' after 'return' in 'mt6577_auxadc_read_raw'. 3).Use 'mt2701' instead of 'auxadc' in dts commit message. 4).Change 'auxadc@' to 'adc@' in mt2701.dtsi. Changes in patch v3: 1).Add '#' before 'io-channel-cells' and change 'auxadc@' to 'adc@' in auxadc binding document. 2).Fix CONFIG_MEDIATEK_MT65XX_AUXADC sequence as alphabetical order. 3).Change the prefix 'MT65XX' to 'MT6577' to match auxadc driver name. 4).Remove the delays stored in 'mt6577_auxadc_device' and use the defined delay directly. 5).Use '-ETIMEDOUT' instead of '-EINVAL'. 6).Return value directly in 'mt6577_auxadc_read_raw'. 7).Add power off and unprepare clock if 'iio_device_register' failed. 8).Change 'Registers' to 'Register'. Changes in patch v2: 1).Change the file name mt65xx_auxadc.c to mt6577_auxadc.c. 2).Add 'depends on ARCH_MEDIATEK || COMPILE_TEST and HAS_IOMEM' for MEDIATEK_MT65XX_AUXADC config. 3).Add check case for return value of 'readl_poll_timeout'. 4).Remove returning 1 and 0 for SCALE and OFFSET. use channel type 'IIO_CHAN_INFO_PROCESSED' instead of 'IIO_CHAN_INFO_RAW'. 5).Remove 'IIO_CHAN_INFO_OFFSET' and 'IIO_CHAN_INFO_SCALE' in 'MT65XX_AUXADC_CHANNEL' channel type. 6).Add check case when auxadc power on failure. if auxadc power on failure, clk_disable_unprepare should be executed. 7).Put 'platform_set_drvdata' before 'iio_device_register'. 8).Fix coding style and spelling error.
