Subject: [PATCH V3 06/10] arm64: dts: imx8mq: Enable both G1 and G2 VPU's with vpu-blk-ctrl
Date:   Sun, 23 Jan 2022 20:31:20 -0600

With the Hantro G1 and G2 now setup to run independently, update
the device tree to allow both to operate.  This requires the
vpu-blk-ctrl node to be configured.  Since vpu-blk-ctrl needs
certain clock enabled to handle the gating of the G1 and G2
fuses, the clock-parents and clock-rates for the various VPU's
to be moved into the pgc_vpu because they cannot get re-parented
once enabled, and the pgc_vpu is the highest in the chain.
