Subject: [PATCH 8/8] MIPS: DTS: Ingenic: Add support for the JZ4755 SoC
Add preliminary support for boards based on the JZ4755 SoC from
Ingenic.
It is a low-power SoC with a MIPS32r1 SoC running at ~432 MHz, and no
FPU.
The JZ4755 SoC is supposed to be newer than the JZ4725B SoC, but its
internals are very close to each other. So JZ4755 DT is reusing many
JZ4725b drivers because JZ4725b support in the kernel appears earlier.
