Subject: ACPI: Move AMBA bus scan handling into arm64 specific directory
X-Git-Tag: v6.6-rc1~180^2~2^5~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fc001b36e50f4136c6b8d9fceaf17fc145ffbd0d;p=thirdparty%2Fkernel%2Flinux.git

ACPI: Move AMBA bus scan handling into arm64 specific directory

Commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific
initialisation into acpi_arm_init()") moved all of the ARM-specific
initialization into acpi_arm_init(). However, acpi_amba.c being outside
of drivers/acpi/arm64 got ignored and hence acpi_amba_init() was not
moved into acpi_arm_init().

Move the AMBA platform bus support into arm64 specific folder and make
acpi_amba_init() part of acpi_arm_init().
