Subject: [PATCH 3/5] staging: fsl-mc/dpio: Use __leXX types where needed
Date: Tue,  6 Mar 2018 11:43:46 -0600	[thread overview]
Message-ID: <20180306174348.26095-4-ruxandra.radulescu@nxp.com> (raw)
In-Reply-To: <20180306174348.26095-1-ruxandra.radulescu@nxp.com>

Structures that are mapped to hardware registers should explicitly
specify the expected endianness for fields larger than 1 byte.
