[PATCH 0/3] Add Avenger96 board support

[Manivannan Sadhasivam]

Hello,

This patchset adds Avenger96 board support. This board is one of the
Consumer Edition boards of the 96Boards family from Arrow Electronics
featuring STM32MP157A MPU and has the following features:
    
SoC: STM32MP157AAC
PMIC: STPMIC1A
RAM: 1024 Mbyte @ 533MHz
Storage: eMMC v4.51: 8 Gbyte
         microSD Socket: UHS-1 v3.01
Ethernet Port: 10/100/1000 Mbit/s, IEEE 802.3 Compliant
Wireless: WiFi 5 GHz & 2.4GHz IEEE 802.11a/b/g/n/ac
          Bluetooth®v4.2 (BR/EDR/BLE)
USB: 2x Type A (USB 2.0) Host and 1x Micro B (USB 2.0) OTG
Display: HDMI: WXGA (1366x768)@ 60 fps, HDMI 1.4
LED: 4x User LED, 1x WiFi LED, 1x BT LED

More information about this board can be found in 96Boards website:
https://www.96boards.org/product/avenger96/

Thanks,
Mani

You can't do that. <STM32_PINMUX('Z', 0, AF3)> has to be declared in 
pincontroller-z. So in your case, you have to define 2 groups for i2C2 
for your default state (the same for the sleep state).

Alex

You can't do that. <STM32_PINMUX('Z', 0, AF3)> has to be declared in 
pincontroller-z. So in your case, you have to define 2 groups for i2C2 
for your default state (the same for the sleep state).

Ah, yes I failed to note pincontroller z. Will fix it in next revision!

[PATCH 3/3] ARM: dts: Add Avenger96 devicetree support based on STM32MP157A

[Manivannan Sadhasivam]

Add devicetree support for Avenger96 board based on STM32MP157A MPU
from ST Micro. This board is one of the 96Boards Consumer Edition board
from Arrow Electronics and has the following features:

SoC: STM32MP157AAC
PMIC: STPMIC1A
RAM: 1024 Mbyte @ 533MHz
Storage: eMMC v4.51: 8 Gbyte
         microSD Socket: UHS-1 v3.01
Ethernet Port: 10/100/1000 Mbit/s, IEEE 802.3 Compliant
Wireless: WiFi 5 GHz & 2.4GHz IEEE 802.11a/b/g/n/ac
          Bluetooth®v4.2 (BR/EDR/BLE)
USB: 2x Type A (USB 2.0) Host and 1x Micro B (USB 2.0) OTG
Display: HDMI: WXGA (1366x768)@ 60 fps, HDMI 1.4
LED: 4x User LED, 1x WiFi LED, 1x BT LED

More information about this board can be found in 96Boards website:

[PATCH 3/3] ARM: dts: Add Avenger96 devicetree support based on STM32MP157A

[Manivannan Sadhasivam]

Add devicetree support for Avenger96 board based on STM32MP157A MPU
from ST Micro. This board is one of the 96Boards Consumer Edition board
from Arrow Electronics and has the following features:

SoC: STM32MP157AAC
PMIC: STPMIC1A
RAM: 1024 Mbyte @ 533MHz
Storage: eMMC v4.51: 8 Gbyte
         microSD Socket: UHS-1 v3.01
Ethernet Port: 10/100/1000 Mbit/s, IEEE 802.3 Compliant
Wireless: WiFi 5 GHz & 2.4GHz IEEE 802.11a/b/g/n/ac
          Bluetooth®v4.2 (BR/EDR/BLE)
USB: 2x Type A (USB 2.0) Host and 1x Micro B (USB 2.0) OTG
Display: HDMI: WXGA (1366x768)@ 60 fps, HDMI 1.4
LED: 4x User LED, 1x WiFi LED, 1x BT LED

More information about this board can be found in 96Boards website:
