I believe the problem is in patch 4/7

config HISILICON_LPC
bool "Support for ISA I/O space on Hisilicon Hip0X"
depends on (ARM64 && ARCH_HISI) || COMPILE_TEST
^^^^^^^^^^^^

the COMPILE_TEST above allowing HISILICON_LPC also for other architectures.
I think we can remove "|| COMPILE_TEST"...I will fix it in v10

Gab

+ select LOGIC_PIO
+ select INDIRECT_PIO
+ help
+ Driver needed for some legacy ISA devices attached to Low-Pin-Count
+ on Hisilicon Hip0X SoC.
