Subject: [PATCH v2 01/19] mtd: rawnand: Propage CS selection to sub operations
Date: Tue, 5 May 2020 12:13:35 +0200 [thread overview]
Message-ID: <20200505101353.1776394-2-boris.brezillon@collabora.com> (raw)
In-Reply-To: <20200505101353.1776394-1-boris.brezillon@collabora.com>
Some controller using the instruction parse infrastructure might need
to know which CS a specific sub-operation is targeting. Let's propagate
this information.
