This is the first step to bring GPU support to the NXP LS1028A SoC. It features a Mali DP500, a Vivante GC7000 and has one DisplayPort output which is driven by a Cadence MHDP controller and PHY.
This was briefly tested with glmark2, a patched mesa kmsro driver [1] to support the mali DP500/GC7000 duo, fixes from mesa merge request 9255 [2] and using ETNA_MESA_DEBUG=no_supertile,no_ts.

The LS1028A SoC errata sheet mentions A-050121 "GPU hangs if clock gating for Rasterizer, Setup Engine and Texture Engine are enabled". The workaround is to disable the corresponding clock gatings.

Thanks, I've applied this series to my etnaviv/next branch.
