If anyone has any objections, please let me know. ------------------ From: Daniel Drake [ Upstream commit 75952cfc7752c52a2b692b59d34ce160d3edabb2 ] Commit d87773de9efe1 ("clocksource/drivers/arm_arch_timer: Default to EL2 virtual timer when running VHE") causes boot to hang on Raspberry Pi 5. The newly-selected EL2 virtual timer does not generate any interrupts, even though the GIC_DIST_ENABLE_SET flag has been confirmed set via readback. It is highly unusual that this timer interrupt is non-operational because this is a standard GIC interrupt corresponding to a standard Cortex-A76 CPU timer. However, Broadcom have confirmed for this SoC: > the interrupt line was never connected in the first place as this was > not identified as being a requirement Remove the corresponding DeviceTree entry.
