Subject: [PATCH v2 04/11] soc/fsl/qbman: Drop set/clear_bits usage
Date: Wed, 19 Apr 2017 16:48:43 -0400 [thread overview]
Message-ID: <1492634930-10765-5-git-send-email-roy.pledge@nxp.com> (raw)
In-Reply-To: <1492634930-10765-1-git-send-email-roy.pledge@nxp.com>
From: Madalin Bucur <madalin.bucur@nxp.com>
Replace PPC specific set/clear_bits API with standard
bit twiddling so driver is portalable outside PPC.
