Date: Mon, 10 Aug 2009 23:05:54 +0300 From: Felipe Balbi <me@...ipebalbi.com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com>, Liam Girdwood <lrg@...mlogic.co.uk>, Mike Rapoport <mike@...pulab.co.il>, linux-kernel@...r.kernel.org Subject: Question about userspace-consumer Hi all, I was reading userspace-consumer file ad was wondering whether would be possible to use that in order to implement what SBS-IF [1] proposes using sbs-enabled devices. For doing that, probably userspace-consumer would have to be able to set_voltage/get_voltage, set/get_current_limit and so on. So I was thinking on changing userspace-consumer to use regulator_get() instead of regulator_bulk_get() and make each instance of userspace-consumer to talk to only and only one regulator. I didn't put down any code but that seems quite plausible if we attach userspace-consumer to the proper regulator(s) on board-file. For doing the implementation and test part, I was thinking on getting a bq2084evm [2] and sniffing the usb-i2c bus in order to write down some code to use that under linux, but that's just implementation details. Anyways, how do you guys feel about it ?
