Subject: [PATCH 1/3] bus: mhi: pci_generic: T99W175: update channel name from AT to DUN
Date: Sun, 6 Jun 2021 21:07:39 +0530 [thread overview]
Message-ID: <20210606153741.20725-2-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20210606153741.20725-1-manivannan.sadhasivam@linaro.org>
From: Jarvis Jiang <jarvis.w.jiang@gmail.com>
According to MHI v1.1 specification, change the channel name of T99W175
from "AT" to "DUN" (Dial-up networking) for both channel 32 and 33,
so that the channels can be bound to the Qcom WWAN control driver, and
device node such as /dev/wwan0p3DUN will be generated, which is very useful
for debugging modem
