Subject: [PATCH] MIPS: BCM47XX: Add Luxul devices to the database
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far only Luxul XWR-1750 router was supported. This adds a set of
other Luxul devices based on BCM47XX. It's a standard support for LEDs
and buttons.

Subject: [PATCH] MIPS: BCM47XX: Add Luxul XAP1500/XWR1750 WiFi LEDs
Some Luxul devices use PCIe connected GPIO LEDs that are not available
until the PCI subsytem and its drivers load. Using the same array for
these LEDs would block registering any LEDs until all GPIOs become
available. This may be undesired behavior as some LEDs should be
available as early as possible (e.g. system status LED). This patch will
allow registering available LEDs while deferring these PCIe GPIO
connected 'extra' LEDs until they become available.

Subject: [PATCH] MIPS: BCM47XX: Add support for Netgear WNR1000 V3
This adds support for detecting this model board and registers some LEDs
and buttons.
There are two uncommon things regarding this device:
1) It can use two different "board_id" ID values.
Unit I have uses "U12H139T00_NETGEAR" value. This magic is also used
in firmware file header. There are two reports (one from an OpenWrt
user) of a different "U12H139T50_NETGEAR" magic though.
2) Power LEDs share GPIOs with buttons.
Amber one seems to share GPIO 2 with WPS button and green one seems
to share GPIO 3 with reset button. It remains unknown how to support
them and handle buttons at the same time. For that reason they aren't
added to the list of supported LEDs.

Subject: [PATCH] firmware: bcm47xx_nvram: support small (0x6000 B) NVRAM
partitions
Some old devices with 4 MiB flashes were using 0x1000 block size and
could use smaller (0x6000 bytes) flash partition for storing NVRAM
content. This adds support for reading NVRAM on Netgear WNR1000 V3.

Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If SoC has a CardBus we can set resources of device at slot 1 only. It's
impossigle to set bridge resources as it simply overwrites device 1
configuration and usually results in Data bus error-s.
