Here is a piece I've noticed very clearly in the GPIO subsystem: ACPI is persued for x86 servers, desktops by all vendors. For embedded x86 it is persued by Intel *ONLY*. We still get several embedded GPIO drivers for x86 that use ISA-style portmapped I/O probing (!) So, hehe, in init/Kconfig there is still the much-debated Kconfig option "EMBEDDED"... Should ACPI for ARM64 be depends on !EMBEDDED?
