[PATCH V2 0/9] ARM: bcm283x: RPi 3 B+ support and other improvements

[PATCH V2 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 
Dave Stevenson's patches [1] 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

[1] - https://github.com/raspberrypi/linux/pull/2502

Changes in V2:
  - add Reviewed-by from Eric and Rob
  - point out that the LAN7515 has a integrated USB HUB
  - fix node names in bcm283x-rpi-lan7515.dtsi

[PATCH V2 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 V2 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 V2 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.

This is necessary because there ain't an EEPROM or a valid OTP.
