Hi everyone: In an effort to bring this kernel driver https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/mfd/rave-sp.c?h=v4.16-rc7 to Barebox, I ended up creating a miniature and extremely simplified version of 'serdev' subsystem which is presented in this patchset. Changes since [v1]: - Blocking read function was added as example of API usage - "serial: Check result of console_unregister()" was converted to become "serial: Drop .remove functions from all drivers" - Minor spelling fixes - Original serdev framework patch modified to allow devices that do not require polling (I don't have such a usecase, but for the sake of being generic I added one line needed for that) - SERIAL_DEV_BUS Kconfig symbol moved into drivers/serial/Kconfig (where it, IMHO, fits much better) - Added a patch to dynamically adjust serdev's polling interval via device paramter. This was warranted by the problems that arose from real-life usage. Feedback is wellcome!
