Mon Feb 27 22:35:24 PST 2017
UART0/1/4/6 interrupts are guesses.
Cc: 96boards at ucrobotics.com
Signed-off-by: Andreas Färber <afaerber at suse.de>
---
v2 -> v3:
* Added remaining UART nodes -- some interrupts are guesses
* Added timer node -- only TIMER1 interrupt known
v1 -> v2:
* Reworded subject
* Added memory at 0 node for Bubblegum-96 (Mark)
* Filled in reserved-memory sub-node for Bubblegum-96 (Mark)
* Added arm-pmu interrupt-affinity property (Mark)
* Changed second GIC reg size 0x1000 -> 0x2000 for Bubblegum-96 (Mark)
* Updated ARCH_OWL to ARCH_ACTIONS (Arnd)
* Renamed s900-bubblegum96.dts to s900-bubblegum-96.dts
* Adopted "actions" vendor prefix
* Dropped irq.h include
* Adopted SPDX-License-Identifier (Rob)
