[PATCH 1/1] clk: qcom: ipq8074: set BRANCH_HALT_VOTED flag for usb master clocks

[Chukun Pan]

Currently, on some boards with older versions of U-Boot, attempting
to disable usb master clocks results in a "stuck at on" warning:

[    3.005088] gcc_usb1_master_clk status stuck at 'on'
[    3.187119] gcc_usb0_master_clk status stuck at 'on'

The USB master clocks of IPQ5332 and IPQ5424 have the BRANCH_HALT_VOTED
flag set, so let's do the same to fix the issue.

These boards run a vendor-specific version of U-Boot, and upgrading to
a newer version could brick the device. Therefore, I think this should
be fixed within the Linux kernel.
