The driver previously grabbed the SD pins for itself, ignoring the pin
controller. Remove this, and allow the pinctrl subsystem to set up the
pins using the device tree mappings. This allows this driver to work on
related devices that have a different pin controller mapping, such as
the MT7688. The hardcoded bit index was incorrect on that device.
The driver now needs a pin controller reference in its device tree node:
sdhci: /* ... */ {
compatible = "ralink,mt7620-sdhci";
pinctrl-names = "default";
pinctrl-0 = <&sdhci_pins>;
// ...
};
This change could break SD controller functionality on existing devices
whose device trees do not specify a pin controller and state for the SD
node.

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.
