Andrew Lunn says:
====================
Modernize mdio-gpio
This patchset is inspired by a previous version by Linus Walleij
It reworks the mdio-gpio code to make use of gpio descriptors instead
of gpio numbers. However compared to the previous version, it retains
support for platform devices. It does however remove the platform_data
header file. The needed GPIOs are now passed by making use of a gpiod
lookup table. e.g:
static struct gpiod_lookup_table zii_scu_mdio_gpiod_table = {
.dev_id = "mdio-gpio.0",
.table = {
GPIO_LOOKUP_IDX("gpio_ich", 17, NULL, MDIO_GPIO_MDC,
GPIO_ACTIVE_HIGH),
GPIO_LOOKUP_IDX("gpio_ich", 2, NULL, MDIO_GPIO_MDIO,
GPIO_ACTIVE_HIGH),
GPIO_LOOKUP_IDX("gpio_ich", 21, NULL, MDIO_GPIO_MDO,
GPIO_ACTIVE_LOW),
},
};

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
