-From 36cc26a362c6ad64ba3d176809847ec60cc40859 Mon Sep 17 00:00:00 2001

-Subject: [PATCH 02/13] MIPS: Lantiq: add SoC specific code for XWAY family
-
-Add support for the Lantiq XWAY family of Mips24KEc SoCs.
-
-* Danube (PSB50702)
-* Twinpass (PSB4000)
-* AR9 (PSB50802)
-* Amazon SE (PSB5061)
-
-The Amazon SE is a lightweight SoC and has no PCI as well as a different
-clock. We split the code out into seperate files to handle this.
-
-The GPIO pins on the SoCs are multi function and there are several bits
-we can use to configure the pins. To be as compatible as possible to
-GPIOLIB we add a function
-
-int ltq_gpio_request(unsigned int pin, unsigned int alt0,
- unsigned int alt1, unsigned int dir, const char *name);
-
-which lets you configure the 2 "alternate function" bits. This way drivers like
-PCI can make use of GPIOLIB without a cubersome wrapper.
-
-The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was
-taken from a 2.4.20 source tree and was never really changed by me since then.
