[PATCH RFC v3 0/4] new bus type SIOX

From: Uwe Kleine-KÃnig
Date: Wed May 11 2016 - 03:01:13 EST


Hello,

this is v3 of the series, the only change is a rebase to a newer
mainline tree (didn't check if this resulted in any changes, worked
without problems) and I added commit logs and sign-offs.

So the open issues still apply which I list here again:

- no device tree binding doc for bus master driver (patch 2)
I will clean this up eventually when (and if) patch 1 gets in.

- the devices should be polled each 25 ms, otherwise a per-device
watchdog resets the device. I'm currently using a workqueue for that,
and on a loaded machine sometimes the watchdog triggers. So maybe I
need a different approach here? But I didn't debug that yet, so this
is just FYI.

Patches 2 and 3 are only to show how patch 1 is intended to be used and
I'd need to rework patch 2 before it can go in and patch 3 probably
needs to go via the gpio tree, but I didn't care to cc the right people
as this series is mainly about patch 1.

Looking forward to feedback
Uwe Kleine-KÃnig
