Subject: [PATCH] usb: xhci-mtk: fix broken streams issue on 0.96 xHCI
The MediaTek 0.96 xHCI controller on some platforms does not
support bulk stream even HCCPARAMS says supporting, due to MaxPSASize
is set a default value 1 by mistake, here use XHCI_BROKEN_STREAMS
quirk to fix it.

Subject: [PATCH] usb: typec: tcpm: Address incorrect values of tcpm psy for
fixed supply
tcpm_pd_build_request overwrites current_limit and supply_voltage
even before port partner accepts the requests. This leaves stale
values in current_limit and supply_voltage that get exported by
"tcpm-source-psy-". Solving this problem by caching the request
values of current limit/supply voltage in req_current_limit
and req_supply_voltage. current_limit/supply_voltage gets updated
once the port partner accepts the request.
