Subject: [PATCH v3 2/4] bus: mhi: core: Move MHI_MAX_MTU to external header file
Date: Thu, 11 Jun 2020 11:13:42 -0700 [thread overview]
Message-ID: <1591899224-3403-3-git-send-email-hemantk@codeaurora.org> (raw)
In-Reply-To: <1591899224-3403-1-git-send-email-hemantk@codeaurora.org>
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.
