If anyone has any objections, please let me know. ------------------ From: Jon Hunter [ Upstream commit 861dbb2b15b1049113887fb95e856f7123eea0cc ] After commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and reset-names") was applied, the HSUART failed to probe and the following error is seen: serial-tegra 3100000.serial: Couldn't get the reset serial-tegra: probe of 3100000.serial failed with error -2 Commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and reset-names") is correct because the "reset-names" property is not needed for 8250 UARTs. However, the "reset-names" is required for the HSUART and should have been populated as part of commit ff578db7b693 ("arm64: tegra: Enable UART instance on 40-pin header") that enabled the HSUART for Jetson AGX Orin. Fix this by populating the "reset-names" property for the HSUART on Jetson AGX Orin.
