[PATCH v6 1/5] irqchip/aspeed-i2c-ic: binding docs for Aspeed I2C Interrupt Controller
From: Brendan Higgins <hidden>
Date: 2017-03-28 05:13:15
Also in:
linux-i2c, lkml, openbmc
Subsystem:
irqchip drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Thomas Gleixner, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Added device tree binding documentation for Aspeed I2C Interrupt
Controller.
Signed-off-by: Brendan Higgins <redacted>
---
Added in v6:
- Pulled "aspeed_i2c_controller" out into a interrupt controller since that is
what it actually does.
