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), }, }; ==================== 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. 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.
