====================
pull-request: can-next 2017-03-03

this is a pull request of 5 patches for net-next/master.

There are two patches by Yegor Yefremov which convert the ti_hecc
driver into a DT only driver, as there is no in-tree user of the old
platform driver interface anymore. The next patch by Mario Kicherer
adds network namespace support to the can subsystem. The last two
patches by Akshay Bhat add support for the holt_hi311x SPI CAN driver.
