8dccafaa28 arm: dts: fix unit-address leading 0s
Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'

Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

8185041f5f ARM: dts: lpc32xx: add device node for IRAM on-chip memory
The change adds a new device node with description of generic SRAM
on-chip memory found on NXP LPC32xx SoC series and connected to AHB
matrix slave port 3.

Note that NXP LPC3220 SoC has 128KiB of SRAM memory, the other
LPC3230, LPC3240 and LPC3250 SoCs all have 256KiB SRAM space,
in the shared DTSI file this change specifies 128KiB SRAM size.

Also it's worth to mention that the SRAM area contains of 64KiB banks,
2 banks on LPC3220 and 4 banks on the other SoCs from the series, and
all SRAM banks but the first one have independent power controls,
the description of this feature will be added with the introduction of
power domains for the SoC series.

9b8ad3fb81 ARM: dts: lpc32xx: reparent SIC1 and SIC2 interrupts from MIC
The change adds separate device nodes for SIC1 and SIC2 interrupt
controllers and reparents all defined SIC1 and SIC2 interrupt
producers to the correspondent interrupt controller, this is needed to
perform switching to a new LPC32xx MIC/SIC interrupt controller driver.

c17e9377aa ARM: dts: lpc32xx: set default clock rate of HCLK PLL
Probably most of NXP LPC32xx boards have 13MHz main oscillator and
therefore for HCLK PLL and ARM core clock rate default hardware
setting is 16 * 13MHz = 208MHz, however a user may vary HCLK PLL/ARM
core rate from 156MHz to about 266MHz for 13MHz clock source.

The change explicitly defines HCLK PLL output rate to default 208MHz
to overwrite any settings done by a bootloader, if needed it can be
redefined in a board DTS file.

ef5f885ec9 arm: dts: lpc32xx: add device nodes for external oscillators
NXP LPC32xx SoC has two external oscillators - one is mandatory and
always on 32768 Hz oscillator and one optional 10-20MHz oscillator,
which is practically always present on LPC32xx boards, because its
presence is needed to supply USB controller clock and by default it
supplies ARM and most of the peripheral clocks, LPC32xx User's Manual
references it as a main oscillator.

The change adds device nodes for both oscillators, frequency of
the main oscillator is selected to be 13MHz by default, this variant
is found on all LPC32xx reference boards.

The device nodes for external oscillators are needed to describe input
clocks of LPC32xx clock controller.

aa29efb445 arm: dts: lpc32xx: move USB controller subdevices into own device node
NXP LPC32xx SoC has one USB OTG controller, which is supposed to work
with an external phy (default is NXP ISP1301).

Practically the USB controller contains 5 subdevices:
- host controller   0x3102 0000 -- 0x3102 00FF
- OTG controller    0x3102 0100 -- 0x3102 01FF
- device controller 0x3102 0200 -- 0x3102 02FF
- I2C controller    0x3102 0300 -- 0x3102 03FF
- clock controller  0x3102 0F00 -- 0x3102 0FFF

The USB controller can be considered as a "bus", because the
subdevices above are relatively independent, for example I2C
controller is the same as other two general purpose I2C controllers
found on SoC.

The change is not intended to modify any logic, but it rearranges
existing device nodes, in future it is planned to add a USB clock
controller device node into the same group.

2a6c656331 arm: dts: lpc32xx: add device node for the second pwm controller
LPC32xx SoCs have two independent PWM controllers, they have different
clock parents, clock gates and even slightly different controls,
each of these two PWM controllers has one output channel. Due to
almost similar controls arranged in a row it is incorrectly assumed
that there is one PWM controller with two channels, fix this problem
in lpc32xx.dtsi, which at the moment prevents separate configuration
of different clock parents and gates for both PWM controllers.
