It seems the i.MX8MM BLK-CTL series are moving forward:
https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=479175
... but I'm unable to wrap my head around how this affects the
devicetree VPU modelling for i.MX8MQ (and also i.MX8MM, i.MX8MP, ...).
Can you clarify that?
Thanks,
Ezequiel
