arm: dts: socfpga: Add a base DTSI for Altera's Arria10 SOC
Browse files Browse the repository at this point in the history 
The Arria 10 is latest SOC+FPGA from the Altera SOCFPGA platform. The Arria10
SOC shares some similarities with the SOCFPGA Cyclone5 and Arria5, but there
are enough differences to warrant a new base dtsi.

The differences are:
* 3 EMAC controllers
* 5 I2C controllers
* 3 SPI controllers
* 1.5 GHZ dual A9s
* Support for DDR4

Besides the usual memory map and IRQ changes, the clock framework will be
different, so this patch just adds the fixed-clocks.
