[PATCH v3 2/5] ARM: tegra: Add legacy interrupt controller nodes

Thierry Reding thierry.reding at gmail.com
Mon Aug 25 23:41:01 PDT 2014


From: Thierry Reding <treding at nvidia.com>

Add device tree nodes for the legacy interrupt controller so that the
driver can get the register ranges from device tree rather than hard-
coding them.

Signed-off-by: Thierry Reding <treding at nvidia.com>

Changes in v3:
- bracket individual tuples in the "reg" property

Changes in v2:
- add chip-specific compatible string
- drop quinary controller on Tegra20
