Date: Thu, 29 Oct 2020 19:45:44 -0700 From: Hemant Kumar <hemantk@...eaurora.org> To: manivannan.sadhasivam@...aro.org, gregkh@...uxfoundation.org Cc: linux-arm-msm@...r.kernel.org, linux-kernel@...r.kernel.org, jhugo@...eaurora.org, bbhatt@...eaurora.org, loic.poulain@...aro.org, netdev@...r.kernel.org, Hemant Kumar <hemantk@...eaurora.org> Subject: [PATCH v11 2/4] bus: mhi: core: 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.
