X-Git-Url: https://git.archive.openwrt.org/?p=openwrt.git;a=commitdiff_plain;h=1f36df63eed55593e6df4e56c29d4c2ceaefdca7

ramips: Add device tree for JCG JHR-N926R

Add a device tree for JCG JHR-N825R

This router is based on a RT3052 and has 4MB of CFI flash and 32MB of
SDRAM. As a special feature, it comes with a two digit seven segment
display that is connected to a pair of daisy-chained 74164 shift
registers that can be controlled via GPIOs.

For details, see https://wikidevi.com/wiki/JCG_JHR-N825R .
