This patch introduces devicetree for Atheros AR9331 SoC (AKA Hornet).
The AR9331 chip is a Wi-Fi System-On-Chip (WiSOC),
typically used in very cheap Access Points and Routers.

Antony Pavlov 3bdf1071ba MIPS: ath79: update devicetree clock support for AR9132
Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. E.g. you can set any clock rate value
in board DTS but it will have no effect on the real clk calculation.

This patch fixes some AR9132 devicetree clock support defects:

  * clk initialization function ath79_clocks_init_dt_ng()
    is introduced; it actually gets pll block base register
    address and reference clock from devicetree;
  * pll register parsing code is moved to the separate
    ar724x_clk_init() function; this function
    can be called from platform code or from devicetree code.

Also mips_hpt_frequency value is set from dt, so the appropriate
clock parameter is added to the cpu@0 devicetree node.

The same approach can be used for adding AR9331 devicetree support.

Antony Pavlov 83fe838466 MIPS: dts: qca: ar9132: use short references for dt nodes
Here are some Sascha Hauer's arguments for using aliases in the dts
files:

 - using aliases reduces the number of indentations in dts files;

 - dts files become independent of the layout of the dtsi files
   (it becomes possible to introduce another bus {} hierarchy between
   a toplevel bus and the devices when you have to);

 - less chances for typos. if &i2c2 does not exist you get an error.
   If instead you duplicate the whole path in the dts file a typo
   in the path will just create another node.

Antony Pavlov 2cdfec1bbb MIPS: dts: qca: ar9132_tl_wr1043nd_v1.dts: drop unused alias node
The TP-LINK TL-WR1043ND board has only one serial port,
so replacing the default of 0 with 0 does nothing useful.

Moreover, the correct name for aliases node is "aliases" not "alias".

An overview of the "aliases" node usage can be found
on the device tree usage page at devicetree.org [1].

Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

Aaro Koskinen 99a7a234c8 MIPS: panic immediately when panic_on_oops
MIPS wants to sleep 5 seconds before panicking when panic_on_oops is set,
with no apparent reason. Remove this feature, since some users may want
their systems to fail as quickly as possible.

Users who want to delay reboot after panic can use PANIC_TIMEOUT.

Rafał Miłecki 2ab71a02c5 MIPS: BCM47xx: Move SPROM driver to drivers/firmware/
Broadcom ARM home routers store SPROM content in NVRAM just like MIPS
ones. To share SPROM code we need to move it out of arch/mips/ to some
common place. We already have bcm47xx_nvram in firmware path and SPROM
should fit there as well.
This driver is responsible for parsing SoC configuration data into a
struct shared between ssb and bcma buses.
This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0
(ARCH_BCM_5301X).
