Subject: [PATCH v5 2/4] bus: mhi: core: Move MHI_MAX_MTU to external header file
Date:   Wed,  5 Aug 2020 23:41:01 -0700
Message-Id: <1596696063-17802-3-git-send-email-hemantk@codeaurora.org>
In-Reply-To: <1596696063-17802-1-git-send-email-hemantk@codeaurora.org>
References: <1596696063-17802-1-git-send-email-hemantk@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently this macro is defined in internal MHI header as
a TRE length mask. Moving it to external header allows MHI
client drivers to set this upper bound for the transmit
buffer size.
