DescriptionIn the Linux kernel, the following vulnerability has been resolved: pmdomain: imx: Fix i.MX8MP VC8000E power up sequence Per errata[1]: ERR050531: VPU_NOC 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 (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. [1] https://www.nxp.com/webapp/Download?colCode=IMX8MP_1P33A
