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 . Signed-off-by: Reinhard Max <reinhard@m4x.de> Reviewed-by: Torsten Duwe <duwe@lst.de> SVN-Revision: 48904
