Failed to get irq using name is NOT fatal as driver will use index to get irq instead, use platform_get_irq_byname_optional() instead of platform_get_irq_byname() to avoid below error message during probe: [ 0.819312] fec 30be0000.ethernet: IRQ int0 not found [ 0.824433] fec 30be0000.ethernet: IRQ int1 not found [ 0.829539] fec 30be0000.ethernet: IRQ int2 not found Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Acked-by: Fugang Duan <fugang.duan@nxp.com> Reviewed-by: Stephen Boyd <swboyd@chromium.org> Signed-off-by: David S.

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.
