[PATCH 0/9] ARM: bcm283x: RPi 3 B+ support and other improvements

[Stefan Wahren]

The main focus of the patch series is to provide support for the new
Raspberry Pi 3 B+ . The rest are parts which missed the merge window for 4.17.

Since there are still some issues with LAN78XX, also apply Phil Elwell's
patches [1] and Dave Stevenson's patches [2] before testing. But they are not
required for the function of this series.    

Relevant to all RPis  : Patch #1, #6
Relevant to RPi 3 B   : Patch #2, #7, #8
Relevant to RPi 3 B+  : Patch #3, #4, #5, #7, #8, #9

[PATCH 1/9] ARM: dts: bcm283x: Fix PWM pin assignment

[Stefan Wahren]

All RPi 1 and 2 boards used the PWM (audio out) on pin 40 and 45.
So it was easy to define them in bcm2835-rpi.dtsi. Starting with RPi 3
this wont work anymore, because it uses pin 40 and 41. Furthermore the
Zero variants doesn't have audio out.

This patch fixes this pin conflict by moving the PWM node to the board-level.

Change summary:
RPi 3 B:      PWM1 45 -> 41
Zero, Zero W: PWM disabled
all other:    no functional change

[PATCH 2/9] ARM: dts: bcm2837: Add missing GPIOs of Expander

[Stefan Wahren]

After commit a98d90e7d588 ("gpio: raspberrypi-exp: Driver for RPi3 GPIO
expander via mailbox service") we are able to control the rest of the
GPIOs of the RPi 3. So add all the missing parts (ACT LED,
Wifi & BT control, HDMI detect) to the DT.

[PATCH 2/9] ARM: dts: bcm2837: Add missing GPIOs of Expander

[Stefan Wahren]

After commit a98d90e7d588 ("gpio: raspberrypi-exp: Driver for RPi3 GPIO
expander via mailbox service") we are able to control the rest of the
GPIOs of the RPi 3. So add all the missing parts (ACT LED,
Wifi & BT control, HDMI detect) to the DT.

[PATCH 4/9] ARM: dts: bcm2837: Add Raspberry Pi 3 B+

[Stefan Wahren]

The Raspberry Pi 3 B+ has the following major differences compared
to the model 3 B:
* Microchip LAN7515 (Gigabit Ethernet)
* Cypress CYW43455 (802.11n/ac and BT 4.2)

We need to add the USB LAN chip so the bootloader can add the MAC address.
This is necessary because there ain't a EEPROM or a valid OTP.

[PATCH 7/9] ARM: multi_v7_defconfig: Enable LAN and BT support for RPi 3 B+

[Stefan Wahren]

The Raspberry Pi 3 B+ has a Microchip LAN7515 (connect via USB) and
a Cypress CYW43455 (connect via UART). This patch enables the necessary
drivers.

Why the separate file? This can be shared?

this comes from the assumption the RPi 3 B+ won't be the only RPi board 
with a LAN7515. Should i fold it in the dts file as long as we don't 
have a second board?

I think it's great as is -- our other network chips are hooked up this
way and it makes 3b+ match all the others.  Also, while I have no
specific knowledge, it seems likely that this would get reused.
