This patch adds 2 functions that allow managed devices to request GPIOs.
These GPIOs will then be managed by drivers/base/devres.c.

Subject: [PATCH 05/73] MIPS: lantiq: reorganize xway code
Inside the folder arch/mips/lantiq/xway, there were alot of small files with
lots of duplicated code. This patch adds a wrapper function for inserting and
requesting resources and unifies the small files into one bigger file.
This patch makes the xway code consistent with the falcon support added later
in this series.

Subject: [PATCH 06/73] MIPS: lantiq: change ltq_request_gpio() call signature
ltq_request_gpio() was using alt0/1 to multiplex the function of GPIO pins.
This was XWAY specific. In order to also accomodate SoCs that require more bits
we use a 32bit mask instead. This way the call signature is consistent between
XWAY and FALC-ON.

Subject: [PATCH 07/73] MIPS: lantiq: make irq.c support the FALC-ON
There are minor differences in how irqs work on xway and falcon socs.
Xway needs 2 quirks that we need to disable for falcon to also work with
this code.
* EBU irq does not need to send a special ack to the EBU
* The EIU does not exist

Subject: [PATCH 11/73] MIPS: lantiq: fix early printk
The code was using a 32bit write operations in the early_printk code. This
resulted in 3 zero bytes also being written to the serial port. This patch
changes the memory access to 8bit.

Subject: [PATCH 18/73] NET: MIPS: lantiq: make etop ethernet work on ase/ar9
Extend the driver to handle the different DMA channel layout for AR9 and
Amazon-SE SoCs. The patch also adds support for the integrated PHY found
on Amazon-SE and the gigabit switch found inside the AR9.

Subject: [PATCH 19/73] NET: MIPS: lantiq: non existing phy was not handled
gracefully
The code blindly assumed that that a PHY device was present causing a BadVA.
In addition the driver should not fail to load incase no PHY was found.
Instead we print the following line and continue with no attached PHY.
etop: mdio probe failed

Subject: [PATCH 21/73] MIPS: lantiq: use devres managed gpios
3.2 introduced devm_request_gpio() to allow managed gpios.
The devres api requires a struct device pointer to work. Add a parameter to ltq_gpio_request()
so that managed gpios can work.

On Falcon SoCs we have a secondary serial port that can be used to help
debug the voice core. For the port to work several clocking bits need to
be activated. We convert the code to clkdev api.

Subject: [PATCH 35/73] MIPS: lantiq: add vr9 support
VR9 is a VDSL SoC made by Lantiq. It is very similar to the AR9.
This patch adds the clkdev init code and SoC detection for the VR9.

From addbb26930d41b35e329d0ad6413cc8d087aa4cc Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Sat, 27 Aug 2011 18:12:26 +0200
Subject: [PATCH 38/73] SPI: MIPS: lantiq: add FALC-ON spi driver
The external bus unit (EBU) found on the FALC-ON SoC has spi emulation that is
designed for serial flash access. This driver has only been tested with m25p80
type chips. The hardware has no support for other types of spi peripherals.

From e125a83872c5b400852efbd451786c42bd395f11 Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>

Subject: [PATCH 40/73] MIPS: lantiq: add xway nand driver
This patch adds a nand driver for XWAY SoCs. The patch makes use of the
plat_nand driver. As with the EBU NOR driver merged in 3.0, we have the
endianess swap problem on read. To workaround this problem we make the
read_byte() callback available via the plat_nand driver causing the nand
layer to do byte reads.
Signed-off-by: John Crispin <blogic@openwrt.org>
TODO : memory ranges

ebu2 and not ebu1 ?

Subject: [PATCH 55/73] MIPS: lantiq: make GPIO3 work on AR9
There are 3 16bit and 1 8bit gpio ports on AR9. The gpio driver needs a hack
at 2 places to make the different register layout of the GPIO3 work properly
with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme
clashes with the new size, we also move the other gpio chips to new offsets.

+ IFX extension for reserving (splitting) cache ways among VPEs. You must
+ give kernel command line arguments vpe_icache_shared=0 or
+ vpe_dcache_shared=0 to enable splitting of icache or dcache
+ respectively. Then you can specify which cache ways should be
+ assigned to which VPE. There are total 8 cache ways, 4 each
+ for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
+ dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
+
+ For example, if you specify vpe_icache_shared=0 and icache_way2=1,
+ then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
+
+ For icache, software is required to make at least one cache way available
+ for a VPE at all times i.e., one can't assign all the icache ways to one
+ VPE.
+
+ By default, vpe_dcache_shared and vpe_icache_shared are set to 1
+ (i.e., both icache and dcache are shared among VPEs)

Changed to use software update, as hw clock was not running on ase. Clock

Subject: [PATCH 72/73] MIPS: lantiq: fix spi for ase, update for clkdev and
platform driver
irqs, gpios, chipselects
updated to use module_platform_driver()
clkdev is a bit hacky, using ltq_spi.0, as specifying no device numbering led to
the mtd driver not hooking up to an spi flash.
