[PATCH 0/2] phy: qcom-qmp-pcie: Add support to keep refclk always on

[Krishna chaitanya chundru]

This series adds support to provide refclk to endpoint even in low
power states.

Due to some platform specific issues with CLKREQ signal, it is not being
propagated to the host and as host doesn't know the clkreq signal host is
not sending refclk. Due to this endpoint is seeing linkdown and going
to bad state.
To avoid those ref clk should be provided always to the endpoint. The
issue is coming only when ep intiates the L1.1 or L1.2 exit and clkreq
is not being propagated properly to the host.
