The ipq806x_gmac_probe() function enables the PTP clock but not the appropriate interface clocks. This means that if the bootloader hasn't done so attempting to bring up the interface will fail with an error like: [ 59.028131] ipq806x-gmac-dwmac 37600000.ethernet: Failed to reset the dma [ 59.028196] ipq806x-gmac-dwmac 37600000.ethernet eth1: stmmac_hw_setup: DMA engine initialization failed [ 59.034056] ipq806x-gmac-dwmac 37600000.ethernet eth1: stmmac_open: Hw setup failed This patch, a slightly cleaned up version of one posted by Sergey Sergeev in: https://forum.openwrt.org/t/support-for-mikrotik-rb3011uias-rm/4064/257 correctly enables the clock; we have already configured the source just before this. Tested on a MikroTik RB3011. Signed-off-by: Jonathan McDowell <noodles@earth.li> Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
