Subject: [PATCH v2 0/5] Linux's serdev framwork port
Date: Thu, 12 Apr 2018 14:33:12 -0700 [thread overview]
Message-ID: <20180412213317.13199-1-andrew.smirnov@gmail.com> (raw)
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!
Thanks,
Andrey Smirnov
