This is Mugilraj, an undergrad at NIT Trichy, India. I'm applying to GSoC'21 for the project IIO driver. So, I need help from you guys with the application process and finding the device to develop a driver.
Since you're not very experienced, I suggest starting with some simple device like plain ADCs. Several vendors like TI or AD offer a huge range of ADCs where we no drivers for. I'd start w/ the simple SPI based devices. It seems they've got quite some overlap (quite simiar protocols), so parts of that maybe could be consolidated into some common library code. For simple ADCs, I've also got yet another(more complex) idea: Create some 'simple-ADC' subsys, which gives a *simple* API for the *simple* cases that's bridged to iio and hwmon (maybe even other subsys's). The idea is getting actual hw drivers for those devices very simple and small, make them usable in IIO as well as hwmon. An interesting question here, that needs some deeper thoughs, is the driver instantiation into the actual subsystems. For example, if some DT says, there's some "ti,adcXYZABC" on the board, what does that actually mean for us ? Where (eg. in which subsys) shall it appear ? Is it an IIO or hwmon device ? Shall that decision even be made only by DT, or do we rely on some other configuration layer ? --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
