MIPS: BMIPS: Add BCM7435 dtsi
Add the bare minimum required to boot a BCM7435-based system: - BMIPS5200 CPU nodes - Level 1 and 2 interrupt controllers - UARTs - EHCI/OHCI controllers Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Cc: linux-mips@linux-mips.org Cc: blogic@openwrt.org Cc: cernekee@chromium.org Cc: Steven.Hill@imgtec.com Patchwork: https://patchwork.linux-mips.org/patch/9971/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
