Subject: [PATCH 3/4] serial: sh-sci: Remove SCIx_RZ_SCIFA_REGTYPE
Date: Fri, 27 Jul 2018 16:09:15 -0500	[thread overview]
Message-ID: <20180727210916.66642-4-chris.brandt@renesas.com> (raw)
In-Reply-To: <20180727210916.66642-1-chris.brandt@renesas.com>

There is no more need for SCIx_RZ_SCIFA_REGTYPE now that
SCIx_SH4_SCIF_REGTYPE can provide the same register/address definitions.

Also, R7S9210 no longer needs a special compatible since the standard
"renesas,scif" will work just fine.
