brcm2708: backport upstream ARM dts commits

Browse source 
This gets us in sync with dts from kernel 4.11. Two patches were already
backported earlier.
I decided to use 03x prefix as it's kind of similar to the 3xx prefix:
3xx - architecture specific patches
It isn't any documented or strict rule though. We don't need to stick to
it if we hit any problems.

Subject: [PATCH] pinctrl: bcm2835: add pull defines to dt bindings
Also delete (unused) private enum from driver.
The pull defines can be used instead if needed.

From 21ff843931b2e5a9b628ac56fd0f2e4355890096 Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Mon, 19 Sep 2016 10:43:18 +0200
Subject: [PATCH] ARM: dts: bcm283x: Define standard pinctrl groups in the gpio
node.
The BCM2835-ARM-Peripherals.pdf documentation specifies what the
function selects do for the pins, and there are a bunch of obvious
groupings to be made. With these created, we'll be able to replace
bcm2835-rpi.dtsi's main "set all of these pins to alt0" with
references to specific groups we want enabled.
Also add pinctrl groups for emmc and sdhost.
Based on patches by Eric Anholt, with fixups by Gerd Hoffmann.

Subject: [PATCH] ARM: bcm2835: dts: add thermal node to device-tree of bcm283x
Add the node for the thermal sensor of the bcm2835-soc
to the device tree.
Signed-off-by: Martin Sperl <kernel@martin.sperl.org>
Reviewed-by: Eric Anholt <eric@anholt.net>
Acked-by: Stefan Wahren <stefan.wahren@i2se.com>
Changelog:
V1 -> V5: generic settings is shared in bcm283x.dtsi, but disabled
moved the compatible string to the SOC specific dtsi
for arm and arm64
V5 -> V6: fix remove 0x prefix from thermal@0x7e212000
Note: there is no arm/boot/dts/bcm2837.dtsi as of now,
so the 32-bit rpi3 dt is not modified.

From 731b26a6ac17f24057c559361c6d0cb7cb79baed Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Thu, 6 Oct 2016 13:15:02 +0200
Subject: [PATCH] ARM: bcm2835: Add names for the Raspberry Pi GPIO lines
The idea is to give useful names to GPIO lines that an implementer
will be using from userspace, e.g. for maker type projects. These are
user-visible using tools/gpio/lsgpio.c
v2: Major rewrite by anholt: Flatten each GPIO line to a line in the
file for better diffing, prefix all expansion header pins with
"P<number>" or "P5HEADER_P<number>" and drop the mostly-unused
GPIO_GEN<smallnumber> names in favor of GPIO<socgpionumber>, fix
extra '[]' on a couple of lines, fix locations of SD_CARD_DETECT,
CAM_GPIO and STATUS_LED, fix HDMI_HPD polarities, rewrite A+ using
unreleased schematics.
v3: More changes by anholt: Drop P<number> / P5HEADER<number>
prefixes. I had been skeptical about adding them, and was
convinced to drop them by Gottfried (who probably has more
experience with GPIOs in educational contexts than the rest of
us). Also drop [] brackets for "is pinmuxed", which didn't seem
to clarify, and were ambiguous for things like the SPI_*-labeled
pins which may or may not actually be pinmuxed to SPI.
v4: Rename B+'s SDA0/SCL0 to match the other boards, despite the
naming on its schematic.

Subject: [PATCH] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines
There are some differences between the schematics and the official firmware
DTS [1]. So based on these additional information the following has been
changed:
* use consistent "CAM_GPIO1" for camera LED
* use consistent "CAM_GPIO0" for camera shutdown
* add "USB_LIMIT" for USB current limit (0=600mA, 1=1200mA)
