Subject: [PATCH 0/4] Increase i.MX8MP VPU
Date: Fri, 30 May 2025 17:17:07 -0500	[thread overview]
Message-ID: <20250530221713.54804-1-aford173@gmail.com> (raw)

Some of the VPU clocks are under rated, even for nominal ratings.
Fix the nominial VPU clocks and clock parents, then introduce
the overdrive clock rates.  The fluster scores don't decrease,
but they do go faster.

This series was adapted from an RFC from Marco Felsch which
was setup to introduce the VC8000E encoder and extacted the
parts that affect the existing infrastructure.

  arm64: dts: imx8mp: Configure VPU clocks for overdrive

Marco Felsch (2):
  arm64: dts: imx8mp: drop gpcv2 vpu power-domains and clocks
  arm64: dts: imx8mp: fix VPU_BUS clock setting
