From 590bfe51838f6345a6a3288507661dc9b7208464 Mon Sep 17 00:00:00 2001 From: Diogo Ivo Date: Fri, 14 Jul 2023 11:10:17 +0100 Subject: [PATCH] arm64: tegra: Fix HSUART for Smaug 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 70006300.serial: Couldn't get the reset serial-tegra: probe of 70006300.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 a63c0cd83720c ("arm64: dts: tegra: smaug: Add Bluetooth node") that enabled the HSUART for the Pixel C. Fix this by populating the "reset-names" property for the HSUART on the Pixel C.
