Subject[PATCH 0/2] MT8195: Add reset for T-PHY (usb/pcie)
Date
Add the resets for TPHY Port 1 which, depending on the board layout,
is used either as USB or PCIe PHY.

This is required on MT8195 Tomato Chromebooks for correct initialization
of the secondary PCI-Express controller, where we have a MT7621 PCIe
WiFi chip.

For reference, the PCIe1 controller devicetree node resets will look
like this:

pcie@112f8000 {
... blurb ...

resets = <&infracfg_ao MT8195_INFRA_RST2_USBSIF_P1_SWRST>,
<&infracfg_ao MT8195_INFRA_RST2_PCIE_P1_SWRST>;
reset-names = "phy", "mac";

... blurb ...
};

This series depends on an earlier one where I introduce the MAC
resets for both PCIe (p0, p1) controllers [1]
