Subject: [PATCH 01/10] bus: mhi: pci_generic: Add mru_default for Quectel EM1xx series
Date: Tue,  1 Mar 2022 21:32:59 +0530	[thread overview]
Message-ID: <20220301160308.107452-2-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20220301160308.107452-1-manivannan.sadhasivam@linaro.org>

From: Yonglin Tan <yonglin.tan@outlook.com>

For default mechanism, the driver uses default MRU 3500 if mru_default
is not initialized. The Qualcomm configured the MRU size to 32768 in the
WWAN device FW. So, we align the driver setting with Qualcomm FW setting.
