Changelog so far: v6: * Add separate cleanup actions for vdd and vref regulators respectively * Change shdn pin name to shutdown. shdn is what the datasheet calls it but "shutdown" seems to be semi-standard, at least in the bindings (Rob orriginally suggested that I change the name in the docs. Figured it made zero sense to have it bear another name in the code) * Dropped maxItems property in vref binding, made binding dual-licensed * Changed name of spi node in binding example v5: * Add vdd supply binding * Reorder include headers -- one of them had escaped the long mechanized hand of the Alphabetron * Drop scan_index and scan_type from channel spec, as the driver doesn't support buffered modes * Drop a useless initialization of a local variable in probe function * Revise dt-bindings patch subject line, revise maintainer and copyright to match the Signed-off: string, drop reference to driver from bindings description * Various readability/cosmetic fixes v4: * Dropped explicit documentation of SPI reg property * Reordered patch series so that dt bindings come first v3: * Fixed silly copy-paste error in Kconfig description v2: * Removed useeless header includes * Dropped needlessly verbose stuff in _read and _probe functions * Dropped useless GPL notice * Lowered log level of shdn pin status in probe function, now it's dev_dbg * Added proper error checking for the GPIO shutdown pin * remove now always returns zero (man, I've been wrong about this for *years* now...) * Added regulator disable action, cleanup is now handled via devm * Drop delay_usecs, use delay.value, delay.unit * Drop config_of, of_match_ptr call * Dropped IIO_BUFFER, IIO_TRIGGERED_BUFFER dependencies, set SPI_MASTER as dependency, fix indenting. * DT binding: use correct id, add reg description (looks pretty standard), dropped spi-max-frequency, fixed dt_binding_check complaints (oops!)
