FW: Writing to I2C device during Barebox boot
I can hardly believe it myself but I have succeeded (i think) in writing a new driver for a I2C chip I use. I probe the driver/device during boot and all seems well. The device shows up in the device tree. So before the init process for the board ends, I would like to write a few values to the device (it controls the PSU, thus the reason for doing it in barebox). I want to do this in the board.c file at the end of the pcm049_devices_init function. Is this the right place? But this is where my linux knowledge is letting me down. How do I get a handle to the device in order to call the write_reg function? Your pointers and help is much appreciated. ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
