[PATCH v5 20/37] MIPS: JZ4740: support newer SoC interrupt controllers

From: Paul Burton
Date: Sun May 24 2015 - 11:28:32 EST


Allow the interrupt controllers of the JZ4770, JZ4775 & JZ4780 SoCs to
be probed via devicetree, supporting the 64 interrupts they provide.

Changes in v5: None
Changes in v4: None
Changes in v3:
- Support JZ4775, and use a more generic "2chip" probe function name
for doing so whilst sharing code with the JZ4780.

Changes in v2: None
