[PATCH 0/2] clk: qcom: negcc-nord: Add the secondary QUSB2 PHY reset

[Shawn Guo]

The series adds the missing secondary QUSB2 PHY reset to negcc-nord
clock driver, so that usb_1_hsphy can be enabled properly on Nord
platform.

[PATCH 1/2] dt-bindings: clock: qcom: nord-negcc: Add the secondary QUSB2 PHY reset

[Shawn Guo]

From: Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>

The NE_GCC block has two eUSB2 PHY block resets - PRIM and SEC - but
right now only the primary is registered. Add the secondary, which is
required by the usb_1 eUSB2 PHY.

Note that the SoC has three eUSB2 PHYs but only these two QUSB2PHY
resets: the HS-only USB20 tile has no dedicated QUSB2PHY reset and
is instead reset as a whole via NE_GCC_USB20_PRIM_BCR.
