[PATCH 01/10] drm/i915/bios: amend child device config parameters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add both some new and some old fields to child device config
parameters. Prepare for switching to just one child device config. Use
naming from struct old_child_dev_config for common fields.

No functional changes.
