Subject: [PATCH 6.8 553/715] phy: qcom: qmp-usb: split USB-C PHY driver
From: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>
[ Upstream commit 19281571a4d5b6049dad9318db081af48818b1d2 ]
In preparation to adding Type-C handling for MSM8998, QCM2290 and SM6115
platforms, create new QMP USB-C PHY driver by splitting mentioned
platforms to a separate file. In future it will also be extended with
support for the DisplayPort handling. It will also be reused later for
such platforms as SDM660, SM6125, SM6150.
