Re: [PATCH V6 2/7] arm64: tegra: Enable AHCI on Jetson TX1

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

 



I have usually split the change in chip .dtsi and board .dtsi/.dts in separate commits. I don't know if that's necessary though.

This does however require a commit message, like

  Add sata node to the Tegra210 device tree, and enable the device and
  assign board-specific properties on Jetson TX1.
