While testing Brandon Anderson patches on foundation v8 model, the model use to hang while booting, because UART is unable to find the clock source. ... ..... ACPI: No dock devices found. acpi_amba_add_device(): amba_device_add() failed (-2) for LINA000A:00 acpi_amba_add_device(): amba_device_add() failed (-2) for LINA000A:01 acpi_amba_add_device(): amba_device_add() failed (-2) for LINA000A:02 acpi_amba_add_device(): amba_device_add() failed (-2) for LINA000A:03 ... .... This patch issued to fix the same issue under foundation v8 platform dsdt asl file.
