This patch makes a few improvements to the way that sdc1 / sdc2 pinctrl is specified on sc7280: 1. There's no reason to "group" the sdc pins into one overarching node and there's a downside: we have to replicate the hierarchy in the board device tree files. Let's clean this up. 2. There's really not a lot of reason not to list the "pinctrl" for sdc1 (eMMC) in the SoC dtsi file. These aren't GPIO pins and everyone's going to specify the same pins. 3. Even though it's likely that boards will need to override pinctrl for sdc2 (SD card) to add the card detect GPIO, we can be symmetric and add it to the SoC dsti file. 4. Let's get rid of the word "on" from the normal config and add a "sleep" suffix to the sleep config. This looks cleaner to me. This is intended to be a no-op change but it could plausibly change behavior depending on how the pinctrl code parses things. One thing to note is that "SD card detect" is explicitly listed now as keeping its pull enabled in sleep since we still want to detect card insertions even if the controller is suspended (because no card is inserted). The pinctrl framework likely did this anyway, but it's nice to see it explicit.

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.
