[PATCH 0/2] clk: qcom: sdm660: keep USB across suspend, give mdss_axi_clk its parent

[Fabricio Akio via B4 Relay <devnull+fabricioakio.gmail.com@kernel.org>]

Two independent fixes to the SDM660 clock controllers, found while
bringing up the Motorola Moto X4 (payton, SDM630).

The first keeps the USB GDSC in retention across system suspend, as
msm8996, msm8998 and sm6375 already do. Switching it off loses the
DWC3 glue's QSCRATCH configuration, and USB does not come back after
resume.

The second sets num_parents on mdss_axi_clk. Without it the branch is
registered with no parent, reports 0 Hz, and enabling it takes no
reference on axi_clk_src.

Tested on a Motorola Moto X4 (XT1900-6) with the sdm660-mainline 7.2.3
tree, where its board file lives. Without the first patch the USB
gadget is gone after an RTC-woken suspend; with it, it re-enumerates
over repeated cycles. With the second, clk_summary shows mdss_axi_clk
at 384 MHz under axi_clk_src instead of 0 Hz with no parent. Both
apply unchanged to next-20260928.
