| Series | MIPS: Add support for more mscc SoCs: Luton, Serval and Jaguar2 | expand |
Hello, > Add a device trees and FIT image support for the Microsemi Jaguar2 SoC > which belongs to same family of the Ocelot SoC. > > It is based on the work of Lars Povlsen <lars.povlsen@microchip.com>. > The i2c device node name are wrongs, I missed it for this submission and will fix it in the next version. For instance i2c_x2sfp_1_a@0 will be named i2c@0.
