[PATCH v4 0/3] AUXADC: Mediatek auxadc driver

Show all headers | View raw

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.
