If anyone has any objections, please let me know. ------------------ From: Jon Hunter [ Upstream commit a7c28483fd57dd0e1487024af70622315320774b ] Commit d87773de9efe ("clocksource/drivers/arm_arch_timer: Default to EL2 virtual timer when running VHE") updated the ARM arch timer driver to use the virtual timer by default if the CPU is running at EL2 with VHE enabled. If the CPU is running at EL2 with VHE enabled but there is no interrupt provided for the virtual timer, then the following warning is displayed: arch_timer: [Firmware Bug]: VHE-capable CPU without EL2 virtual timer interrupt This warning is observed on Tegra194 platforms. Tegra194 SoC includes NVIDIA Carmel ARM v8.2 CPUs and support an EL2 virtual timer. Fix the above warning by adding the PPI for the EL2 virtual timer interrupt for Tegra194.
