Subject: [PATCH v1 0/3] This series adds ethernet support for RPi4.
Date: Fri, 11 Oct 2019 20:48:18 +0200	[thread overview]
Message-ID: <20191011184822.866-1-matthias.bgg@kernel.org> (raw)

From: Matthias Brugger <mbrugger@suse.com>

Raspberry Pi 4 uses the broadcom genet chip in version five.
This chip has a dma controller integrated. Up to now the maximal
burst size was hard-coded to 0x10. But it turns out that Raspberry Pi 4
does only work with the smaller maximal burst size of 0x8.

This series adds a new optional property to the driver, dma-burst-sz.
The very same property is already used by another drivers in the kernel.


Matthias Brugger (3):
  dt-bindings: net: bcmgenet add property for max DMA burst size
  net: bcmgenet: use optional max DMA burst size property
  ARM: dts: bcm2711: Enable GENET support for the RPi4
