This series introduces initial support for the Ingenic JZ4780 SoC and
the Imagination Technologies MIPS Creator CI20 board which is built
around it. In the process the existing JZ4740 & qi_lb60 code gains
initial support for using DeviceTree such that much of the existing
platform code under arch/mips/jz4740 can be shared.
The series has undergone quite a bit of restructure since v2. Each
patch contains a changelog indicating its differences, but a rough
overview for changes across the series would be:
- s/jz47xx/ingenic/ in various places, to reflect the fact that
Ingenic have changed the naming scheme for their newest SoCs
(now Mxxx).
- Restructure the Kconfig entries to provide a MACH_INGENIC
indicating and Ingenic SoC, and have boards select the
appropriate SoC symbol.
- Merge DT binding documentation where SoC bindings differ only
by compatible strings.
- Capitalise "JZ" in SoC names, where not identifiers in code,
to match the way Ingenic write them.
- Further clean up the Ingenic SoC interrupt controller driver
and move it under drivers/irqchip/.
Review appreciated, and hopefully this can make it into v4.2.
Thanks,
Paul
