Description: VC8000E reset de-assertion edge and AXI clock may have a timing issue. Workaround: Set bit2 (vc8000e_clk_en) of BLK_CLK_EN_CSR to 0 to gate off both AXI clock and VC8000E clock sent to VC8000E and AXI clock sent to VPU_NOC m_v_2 interface during VC8000E power up(VC8000E reset is de-asserted by HW) Add a bool variable is_errata_err050531 in 'struct imx8m_blk_ctrl_domain_data' to represent whether the workaround is needed. If is_errata_err050531 is true, first clear the clk before powering up gpc, then enable the clk after powering up gpc.

Affected files ============== The file(s) affected by this issue are: drivers/pmdomain/imx/imx8m-blk-ctrl.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/87af3ebc112fb3f06753794390daf0f665f151b4 https://git.kernel.org/stable/c/c498928f85651b56a4041ea165a22037eae69580 https://git.kernel.org/stable/c/4ff3960f3527189bc115a927ed3561c758f562f1 https://git.kernel.org/stable/c/4907f4c2d98b97e640191af5bcf2814ee1034b76 https://git.kernel.org/stable/c/25e252bcf1593b420b12a7231d9dd64b885a2ae2
