From 9e0235e97ea2617beaacaa16ab5f0b9e75f4680e Mon Sep 17 00:00:00 2001
|
||||
From: John Crispin <blogic@openwrt.org>
|
||||
Date: Wed, 30 Mar 2011 09:27:47 +0200
|
||||
Subject: [PATCH 01/13] MIPS: Lantiq: Add initial support for Lantiq SoCs
|
||||
|
||||
Add initial support for Mips based SoCs made by Lantiq. This series will add
|
||||
support for the XWAY family.
|
||||
|
||||
The series allows booting a minimal system using a initramfs or NOR. Missing
|
||||
drivers and support for Amazon and GPON family will be provided in a later
|
||||
series.
|
||||
|
||||
[Ralf: Remove some cargo cult programming and fixed formatting.]

|

Subject: [PATCH 03/13] MIPS: Lantiq: Add PCI controller support.
|
||||
|
||||
The Lantiq family of SoCs have a EBU (External Bus Unit). This patch adds
|
||||
the driver that allows us to use the EBU as a PCI controller. In order for
|
||||
PCI to work the EBU is set to endianess swap all the data. In addition we
|
||||
need to make use of SWAP_IO_SPACE for device->host DMA to work.
|
||||
|
||||
The clock of the PCI works in several modes (internal/external). If this
|
||||
is not configured correctly the SoC will hang.

Subject: [PATCH 08/13] MIPS: Lantiq: Add more gpio drivers
|
||||
|
||||
The XWAY family allows to extend the number of gpios by using shift registers or latches. This patch adds the 2 drivers needed for this. The extended gpios are output only.

|

Subject: [PATCH 11/13] MIPS: Lantiq: Add ethernet driver
|
||||
|
||||
This patch adds the driver for the ETOP Packet Processing Engine (PPE32)
|
||||
found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit
|
||||
ethernet work. Support for all 8 dma channels, gbit and the embedded switch
|
||||
found on the ar9/vr9 still needs to be implemented.
