Raspbian and Fedora have decided to support the Pi3 in 32-bit mode for
now, so it's useful to be able to test that mode on an upstream
kernel. It's also been useful for me to use the same board for 32-bit
and 64-bit development.

Subject: [v2] ARM: bcm2835: dts: fix uart0 pinctrl node names
From: Baruch Siach <baruch@tkos.co.il>
X-Patchwork-Id: 9544261
Message-Id: <f37d02c769d0e2b6db2529cafb86b5fdd1e09a94.1485715259.git.baruch@tkos.co.il>

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.
Fixes: 21ff843931b ("ARM: dts: bcm283x: Define standard pinctrl groups in the gpio node.")

* Rename also uart0_gpio30 (Stefan)

According to the BCM2835 ARM Peripherals document uart1 doesn't map to pins
36-39, but uart0 does.
Also, split into separate Rx/Tx and CST/RTS groups to match other uart nodes.

An alias name should have an index number even when it is the only of its type.
This allows U-Boot to add the local-mac-address property. Otherwise U-Boot
skips the alias.
