From mboxrd@z Thu Jan 1 00:00:00 1970 From: mark.rutland@arm.com (Mark Rutland) Date: Thu, 31 Jan 2013 12:15:23 +0000 Subject: [PATCHv5 00/16] Unify arm_generic and arch_timer drivers Message-ID: <1359634539-9580-1-git-send-email-mark.rutland@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This is an updated version of v4 of the series I posted 2 weeks ago [1]. The only change is the last two patches, moving over to always using the virtual counters. I've left these as separate patches rather than folding them in to allow them to be reviewed more easily. I've tested the series on a TC2 and an AArch64 model, and I'm happy that it all works. Stephen, Thomas: I've not folded the CLOCKSOURCE_OF_DECLARE patch as it's unclear what path everything is going to take, and I don't a have a tree with Stephen's patch that I can base on. There's already a dependency on the timer broadcast rework, and adding more branches to the mix is going to get messy. I can take the version with ifdefs under the assumption we remove them in a later patch once Stephen's patch is in. Does that sound ok? Thanks, Mark.
