From 93258369b24dffa0465eec60d6fdf4f316445970 Mon Sep 17 00:00:00 2001 From: Hemant Kumar Date: Thu, 7 May 2020 21:00:41 -0700 Subject: [PATCH] bus: mhi: host: Move MHI_MAX_MTU to external header file 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.
