To: u-boot
This patch series add support for MSCC Jaguar2 SOC family. In this
family there are the following boards: Jagaur2(pcb110),
Jaguar2-48(pcb111) and Serval2(pcb112).
This is based off the u-boot-mips/next repository
This version address comments from Daniel Schwierzeck
<daniel.schwierzeck@gmail.com>
v4-changes:
- remove sysreset driver
v3-changes:
- remove any target specific code from mscc-common.c
v2-changes:
- create sysreset driver for Jaguar2
- update pinctrl
Horatiu Vultur (6):
pinctrl: mscc: Add gpio and pinctrl for Jaguar2 SOC family
MSCC: Add support for Jaguar2 SOC family
MSCC: Add device tree for Jaguar2 board
MSCC: Add device tree for Jaguar2-48 board
MSCC: add device tree for Serval2 board
MSCC: Add board support for Jaguar2 SOC family
