97af8e1cb3 MIPS: Malta: Probe pflash via DT 
Add the DT nodes required to probe the CFI compatible parallel monitor
flash found on the Malta development board, and remove the platform
code that was previously doing it. Delete the now-empty malta-platform.c
file. Adjust the Malta defconfigs that enable MTD & the pflash/CFI
driver to enable CONFIG_MTD_PHYSMAP_OF rather than CONFIG_MTD_PHYSMAP in
order to preserve their behaviour.

38ec82fe21 MIPS: Malta: Probe interrupt controllers via DT 
Probe the CPU, GIC & i8259 interrupt controllers present in the Malta
system using device tree. This enables interrupts to be provided to
devices using device tree as they are moved over to being probed using
it.

Since Malta is very configurable it's unknown whether a GIC will be
present at compile time. In order to support both cases the
malta_dt_shim code is added in order to detect whether a GIC is present,
adjusting the DT to route interrupts correctly and nop out the GIC node
if no GIC is found.

c11e3b48db MIPS: SEAD3: Probe UARTs using DT 
Probe the UARTs on SEAD3 boards using device tree rather than platform
code, in order to reduce the amount of the latter. This requires that
CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig.
The SEAD3 DT shim code is extended to read bootloader environment
variables to determine the appropriate UART & mode for kernel console
output & set the stdout-path property of the chosen node accordingly.

In contrast to the old platform code, which appears to have only ever
set "console=ttyS0,38400n8r" with the code in console_config never
having an effect, this will honor the "yamontty" environment variable to
select between the 2 UARTs on the board and then check the "modetty0" or
"modetty1" variable as appropriate to determine the UART configuration.

b6d5e47e67 MIPS: SEAD3: Probe interrupt controllers using DT 
Probe the CPU interrupt controller & optional Global Interrupt
Controller (GIC) using devicetree rather than platform code. Because the
bootloader on SEAD3 does not provide a device tree to the kernel & the
device tree is always built in, we patch out the GIC node during boot if
we detect that a GIC is not present in the system.

The appropriate IRQ domain is discovered by platform code setting up
device IRQ numbers temporarily. It will be removed by further patches
which move the devices towards being probed via device tree.

No behavioural change is intended by this patch.

the generic OHCI driver successfully on a JZ4770-based board.

The device is disabled by default; boards that want to use it can
override the "status" property. The mass-production Qi LB60 boards
don't use the USB host controller.

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.

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.

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].

are, and we can later decide to remap these in software to provide proper

f7f797cfc6 MIPS: dts: qca: ar9132_tl_wr1043nd_v1.dts: use "ref" for reference clock name 
Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. The ar724x_clocks_init() function
recreates the clocks from scratch so devicetree clock
information is dropped. After adding the code which picked up
reference clock from devicetree I have found
that kernel does not boot anymore. The SPI and UART drivers
can't get clk; here are the bootlog error messages:

    of_serial: probe of 18020000.uart failed with error -22
    ath79-spi: probe of 1f000000.spi failed with error -22

The problem is that clock code assumes that reference clock
name is "ref" but current dts-file uses another name: "oscillator".

This patch fixes the problem by changing external oscillator
dt node name to "ref".

Please note that there is an alternative solution for the problem:
