* Bump Raspberry Pi kernel to 5.4 Bump kernel to the downstream Raspberry Pi 5.4 kernel. Drop patches already merged upstream and use rebased patches for USB reset controller (required for U-Boot 2020.10 for USB SSD boot). * Add compatible node for upstream U-Boot Add brcm,bcm2835-pl011 to make upstream U-Boot bind with the bcm283x_pl011 driver. This allows to boot with the device tree provided by the Raspberry Pi Linux kernel 5.4 even without enable_uart=1.

Subject: [PATCH 5/8] ARM: dts: bcm2711: Add firmware usb reset node
|
|
|
|
Now that the reset driver exposing Raspberry Pi 4's firmware based USB
|
|
reset routine is available, let's add the device tree node exposing it.
