Downstream kernel uses pins 32, 33 as UART0 (PL011) Rx/Tx to communicate with
the Bluetooth chip. So ALT3 of these pins is most likely not CTS/RTS. Change
the node name to reflect that. This matches section 6.2 "Alternative Function
Assignments" in the BCM2835 ARM Peripherals document.
With this change in place, adding
&uart0 {
pinctrl-names = "default";
pinctrl-0 = <&uart0_gpio32 &gpclk2_gpio43>;
status = "okay";
};
to bcm2837-rpi-3-b.dts does the right thing on my Raspberry Pi 3.
Pins 30, 31 are CTS/RTS of UART0 in alternate function 3. Rename uart0_gpio30
as well.
While at it, fix a little typo in a nearby comment.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
