Subject: [PATCH V2 1/8] dmaengine: bcm2835: set residue_granularity field
Date: Thu, 7 Jan 2016 17:32:59 +0000 [thread overview]
Message-ID: <1452187987-2605-2-git-send-email-kernel@martin.sperl.org> (raw)
In-Reply-To: <1452187987-2605-1-git-send-email-kernel@martin.sperl.org>
From: Martin Sperl <kernel@martin.sperl.org>
bcm2835-dma supports residue reporting at burst level but didn't report
this via the residue_granularity field.
