CVE-2026-72007

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx: Fix i.MX8MP VC8000E power up sequence

Per errata[1]: ERR050531: VPUNOC power down handshake may hang during VC8000E/VPUMIX power up/down cycling. Description: VC8000E reset de-assertion edge and AXI clock may have a timing issue. Workaround: Set bit2 (vc8000eclken) of BLKCLKENCSR to 0 to gate off both AXI clock and VC8000E clock sent to VC8000E and AXI clock sent to VPUNOC mv_2 interface during VC8000E power up(VC8000E reset is de-asserted by HW)

Add a bool variable iserrataerr050531 in 'struct imx8mblkctrldomaindata' to represent whether the workaround is needed. If iserrataerr050531 is true, first clear the clk before powering up gpc, then enable the clk after powering up gpc.
