Subject: [PATCH 1/2] ARM: dts: bcm2837: Add Raspberry Pi 3 B+
|
|
|
|
The Raspberry Pi 3 B+ has the following major differences compared
|
|
to the model 3 B:
|
|
* Microchip LAN7515 (Gigabit Ethernet with integrated USB 2.0 HUB)
|
|
* 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 an EEPROM or a valid OTP.
