For the non-working case, the code was stuck in a readl() in
http://lxr.free-electrons.com/source/drivers/usb/host/xhci.c#L91
because
http://lxr.free-electrons.com/source/drivers/usb/dwc3/dwc3-of-simple.c#L126
was disabling the wrong clocks when removing hcd.1 (it was disabling
the clock of hcd.0). That's why the readl() went stuck when removing
hcd.0
The patch however addresses the clock assignment from the .dtsi
file. Most probably it went into openwrt here:
https://dev.openwrt.org/browser/trunk/target/linux/ipq806x/patches-3.18/101-ARM-qcom-add-USB-nodes-to-ipq806x-ap148.patch?rev=45261
copied from Qualcomms attempt here: https://lkml.org/lkml/2015/11/20/116
Now unloading and repeated module loading is working just fine,
no matter if you'd remove dwc3-of-simple or dwc3.

Many (most?) devices can't boot raw kernel using tftp and probably none
allows flashing it. It's way more usable to have TRX with kernel
containing initrams as such an image can be actually flashed.
An exception are Buffalo devices which have recovery mode with support

Right now all brcm2708 patches are extracted from the non-mainline
raspberrypi/linux git tree. Many of them are hacks and/or are unneeded
in LEDE. Raspberry Pi is getting better and better mainline support so
it would be nice to finally start maintaining patches in a cleaner way:
1) Backport patches accepted in upstream tree
2) Start using upstream drivers
3) Pick only these patches that are needed for more complete support
Handling above tasks requires grouping patches - ideally using the same
prefixes as generic ones. It means we should rename existing patches to
use some high prefix. This will allow e.g. use 0xx for backported code.

P&W (full name: Shenzhen Progress&Win Technologies) R602N (could be also
labeled as R602F, R602, etc.) is a simple N300 router with 5-port
10/100 Mbps switch, non-detachable antennas and USB.
CPE505 is an outdoor CPE with PoE support and detachable antennas.
Both devices are based on Qualcomm/Atheros QCA9531 v2.
Common specification:
- 650/597/216 MHz (CPU/DDR/AHB)
- 64 MB of RAM (DDR2)
- 16 MB of FLASH
- UART (J2) header on PCB
R602N specification:
- 5x 10/100 Mbps Ethernet
- 1x USB 2.0
- 2T2R 2.4 GHz with external LNA and PA (SE2576L), up to 28 dBm
- 2x external, non-detachable antennas
- 7x LED, 1x button
CPE505N specification:
- 2x 10/100 Mbps Ethernet (both ports support passive PoE 12-24 V)
- 2T2R 2.4 GHz with external LNA and PA (SKY65174-21), up to 30 dBm
- 2x external, detachable antennas (RP-SMA connectors)
- 1x RGB LED, 2x LEDs (in RJ45 sockets), 1x button
Flash instructions:
It seems that there are many different versions of the firmware which
these devices are shipped with. The generic/standard one is based on
some modified OpenWrt and LEDE firmware can be flashed directly from
vendor's webgui or with sysupgrade (root password is "admin123").
Before flashing, make sure (use "fw_printenv") that the kernel load
address in your device is set to "0x9f050000" (bootcmd variable is
"bootm 0x9f050000"). If your device uses different load address, you
should first change it, under vendor's firmware, with command:
fw_setenv bootcmd "bootm 0x9f050000 || bootm OLD_ADDRESS"
Where OLD_ADDRESS is previous kernel load address (in CPE505 version
I got access to, it was "0x9fe80000"). This will allow you to use
both the vendor's and LEDE firmware.
If version of your device contains empty U-Boot environment (you will
get information about this after issuing "fw_printenv"), you should
use U-Boot, serial line access and TFTP to perform firmware upgrade:
1. tftp 0x80060000 lede-ar71xx-generic-...-squashfs-sysupgrade.bin
2. erase 0x9f050000 +$filesize
3. cp.b $fileaddr 0x9f050000 $filesize
4. setenv bootcmd "bootm 0x9f050000 || bootm OLD_ADDRESS"
5. saveenv && reset
These devices contain also web recovery mode inside U-Boot. It can be
started with pressing the reset button for around 3 seconds just after
the device powerup. Web recovery panel is available on "192.168.10.9"
and to be able to use it, IP on your PC must be set to "192.168.10.10".
Make sure to change kernel load address before using recovery mode or
the U-Boot will not be able to load LEDE firmware.

At the moment as a workaround definition for scm firmware in DT is used as if it is

By design unlike other qcom boards ipq do not use clocks to connect to scm.
Considering this we're removing from DT and scm driver clocks for ipq boards.

The SMP state within vpe-mt.c is determined by CONFIG_SMP option.
A runtime check is needed if VPE functionality
should be used with a kernel image that supports SMP.
This fix introduces a check for 'nosmp' command line option
if CONFIG_SMP kernel configuration option is enabled.
Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP
(that activates CONFIG_SMP) is enabled within kernel configuration
and the 'nosmp' command line argument is given to disable SMP at runtime.
Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS.
With this patch setting the 'nosmp' parameter is enough.
In general, concurrent usage of FXS and SMP
is incompatible and will cause kernel panics.

It is not needed for anything on the system and skipping this saves some
build time, especially in cases where there is nothing to do.

The problem is caused by the incorrect handling of the parent inode's
i_nlink count for the dentry to be RENAME_EXCHANGED. There are 3 cases
to consider. Assume we want to RENAME_EXCHANGE struct dentry *a and
struct dentry *b, and inode_a is pointed to by dentry_a, inode_b is
pointed to by dentry_b:
1. If inode_a is a directory, but inode_b isn't, then we must decrease
the i_nlink count of old_dir_i, and increase the i_nlink of new_dir_i.
2. If inode_a isn't a directory, but inode_b is a directory, then we
must increase the i_nlink of old_dir_i, and decrease the i_nlink count
of new_dir_i.
3. If the types of inode_a and inode_b are the same, we don't change the
i_nlink for either old_dir_i or new_dir_i.

Switch to the common LED related status_led_blink_* functions in
set_state() as it's done in most of other targets.
Also, use "status_led_on" instead of "status_led_set_heartbeat"
and incorrect "status_led_set_on" in the "done" state.
Moreover, remove outdated comment from the script.

When the device name doesn't already contain "RouterBOARD", this patch adds
this string to the machine name.
Most NOR devices already have "RouterBOARD" in their hardware-stored device name,
but not all of them.
This patch also makes the code more robust against buffer overflows.

This driver supports CPU-specific idle features on recent Intel
processors. It does not conflict with the ACPI idle driver and
that driver will continue to be used for unsupported and non-Intel
processors.

The x86_64 build already has the k10temp driver for AMD processors
built in, so this patch adds the coretemp driver for the same

The available amount of coherent DMA memory is very limited. On Linux
4.4 this issue was worked around by increasing the pool size.
It turns out that using coherent memory here is completely unnecessary.
This change reworks the driver code to use kzalloc+dma_map_single
instead.

Do not patch upstream files, overwrite them entirely. The upstream files
are buggy for a number of devices and this significantly simplifies the

The Netgear WNDR4300, equipped with an Atheros AR8327 Gigabit Switch,
has two LEDs on each port for monitoring LAN activity, but it currently
only uses one. Fix the configuration to use both.
The patch provides this new configuration:
- green LED: 1 Gbps link, 4Hz blink frequency
- amber LED: 10/100 Mbps link. 4Hz for 100Mbps, 2Hz for 10Mbps

At now there is no general rule about what part of (or whole) machine
name string should be used for board name assignment/detection and every
target handles this in a different way.
For most of the boards in ar71xx we already use only part of the string,
generally without the vendor name.
This shortens wildcards patterns in case statement for board name
assignment, wherever possible (e.g. where it won't be misleading).

Be consistent and always use double quotes for case statement patterns,
as in other targets. With this approach it should be less confusing for
users adding support for new devices.
Also, be consistent with MikroTik boards wildcard pattern.
