Subject: Merge patch series "dm: core: Avoid multiple calls to fdt_parent_offset()"
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=314fdd2e7392bc3480104a1f15001f0f6f25a4dd;p=u-boot.git

Merge patch series "dm: core: Avoid multiple calls to fdt_parent_offset()"

Jonas Karlman <jonas@kwiboo.se> says:

Use of fdt_parent_offset() is very expensive as detailed by the function
documentation:

  NOTE: This function is expensive, as it must scan the device tree
  structure from the start to nodeoffset, *twice*.

This series remove multiple calls to fdt_parent_offset() or
ofnode_get_parent() when instead a single call can be made and the
returned value can be reused.

This series help reduce boot time by around:
- ~137ms on a Radxa ROCK Pi 4 (RK3399)
- ~33ms on a Radxa ZERO 3W (RK3566)
