Enable LPC interrupt controller on MIPS LS7A systems

[PATCH 0/2] Enable LPC interrupt controller on MIPS LS7A systems

Posted by Icenowy Zheng 2 months ago

This patchset tries to enable support for LPC interrupts on MIPS-based
Loongson systems with Loongson 7A1000 PCH chip.

The corresponding irqchip support (along with the DT binding) is already
added to the tip tree.

Tested on a Haier Boyue G51 system with legacy i8042 keyboard/mouse as
integrated ones.

This patchset is splitted from the original patchset that contains both
driver part and DT part.

Icenowy Zheng (2):
  MIPS: Loongson64: dts: Sort nodes
  MIPS: Loongson64: dts: Add node for LS7A PCH LPC

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
