It also changes the FDT clock-frequency from 100000000 to 1843200 Hz to match the emulated UART model. The FDT clock property is retained. Changes since v3: - Add a separate patch to correct the FDT UART clock frequency. - Carry Bibo Mao's Reviewed-by for the ACPI change. - Clarify the ACPI commit message. Testing: - All five LoongArch ACPI bios-tables-test subtests pass. - The generated DTB reports clock-frequency = 1843200 for all four UART nodes. pillow (4): bios-tables-test-allowed-diff.h: Allow LoongArch DSDT.* hw/loongarch/virt-acpi-build: Drop UART _DSD clock and add _STA tests/data/acpi/loongarch64: Update expected DSDT.* hw/loongarch/virt: Fix UART clock frequency in FDT hw/loongarch/virt-acpi-build.c | 12 +----------- hw/loongarch/virt-fdt-build.c | 2 +- tests/data/acpi/loongarch64/virt/DSDT | Bin 4603 -> 4379 bytes tests/data/acpi/loongarch64/virt/DSDT.memhp | Bin 5824 -> 5600 bytes tests/data/acpi/loongarch64/virt/DSDT.numamem | Bin 4609 -> 4385 bytes .../data/acpi/loongarch64/virt/DSDT.topology | Bin 4905 -> 4681 bytes 6 files changed, 2 insertions(+), 12 deletions(-) base-commit: 8967b2fe1b2aaae3c29e207d85fab901d580a2dc -- 2.56.0
