On some of i.MX SoCs like i.MX8QXP, there is ONLY one IRQ for each GPIO bank, so it is better to check the IRQ count before getting second IRQ to avoid below error message during probe: [ 1.070908] gpio-mxc 5d080000.gpio: IRQ index 1 not found [ 1.077420] gpio-mxc 5d090000.gpio: IRQ index 1 not found [ 1.083766] gpio-mxc 5d0a0000.gpio: IRQ index 1 not found [ 1.090122] gpio-mxc 5d0b0000.gpio: IRQ index 1 not found [ 1.096470] gpio-mxc 5d0c0000.gpio: IRQ index 1 not found [ 1.102804] gpio-mxc 5d0d0000.gpio: IRQ index 1 not found [ 1.109144] gpio-mxc 5d0e0000.gpio: IRQ index 1 not found [ 1.115475] gpio-mxc 5d0f0000.gpio: IRQ index 1 not found Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
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.
