[PATCH v4 2/5] mei: vsc: Prevent timeout error with added delay post-firmware download

by Wentong Wu

After completing the firmware download, the firmware requires some time to become functional. This change introduces additional sleep time before the first read operation to prevent a confusing timeout error in vsc_tp_xfer().

[PATCH v1] pmdomain: imx8m-blk-ctrl: fix suspend/resume order

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> During the probe, the genpd power_dev is added to the dpm_list after blk_ctrl due to its parent/child relationship. Making the blk_ctrl suspend after and resume before the genpd power_dev. As a consequence, the system hangs when resuming the VPU due to the power domain dependency. To ensure the proper suspend/resume order, add a device link betweem blk_ctrl and genpd power_dev. It guarantees genpd power_dev is suspended after and resumed before blk-ctrl.

This patch is buggy and should not go into the stable trees. It has already been reverted upstream in the mips-fixes.
