All preparation work is done, so the platform can finally
be moved into ARCH_MULTIPLATFORM. This requires a small

All device drivers have stopped relying on mach/*.h headers,
so move the remaining headers into arch/arm/mach-lpc32xx/lpc32xx.h
to prepare for multiplatform builds.The mach/entry-macro.S file has been unused for a long time now
and can simply get removed.Link: https://lore.kernel.org/r/20190809144043.476786-13-arnd@arndb.de

The lpc32xx_loopback_set() function in hte lpc32xx_hs driver is the
one thing that relies on platform header files. Move that into the
core platform code so we only need a variable declaration for it,

Setting the phy mode requires touching a platform specific
register, which prevents us from building the driver without
its header files.Move it into a separate function in arch/arm/mach/lpc32xx

The lpc_eth driver uses a platform specific method to find
the internal sram. This prevents building it on other machines.Rework to only use one function call and keep the other platform
internals where they belong. Ideally this would look up the
sram location from DT, but as this is a rarely used driver,
I want to keep the modifications to a minimum.Link: https://lore.kernel.org/r/20190809144043.476786-7-arnd@arndb.de

Pull ARM SoC platform updates from Arnd Bergmann:
"We get support for three new 32-bit SoC platforms this time.The amount of changes in arch/arm for any of them is miniscule, as all
the interesting code is in device driver subsystems (irqchip, clk,
pinctrl, ...) these days. I'm listing them here, as the addition of
the Kconfig statement is the main relevant milestone for a new
platform. In each case, some drivers are are shared with existing
platforms, while other drivers are added for v4.7 as well, or come in
a later release.- The Aspeed platform is probably the most interesting one, this is
what most whitebox servers use as their baseboard management
controller. We get support for the very common ast2400 and ast2500
SoCs. The OpenBMC project focuses on this chip, and the LWN
article about their ELC 2016 presentation athttps://lwn.net/Articles/683320/
triggered the submission, but the code comes from IBM's OpenPOWER
team rather than the team at Facebook. There are still a lot more
drivers that need to get added over time, and I hope both teams can
work together on that.- OXNAS is an old platform for Network Attached Storage devices from
Oxford Semiconductor. There are models with ARM10 (!) and
ARM11MPCore cores, but for now, we only support the original ARM9
based versions. The product lineup was subsequently part of PLX,
Avago and now the new Broadcom Ltd.https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
has some more information.
- V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
cores and is related to the existing Realview / Versatile Express
lineup, but without MMU.We now support various NOMMU platforms, so adding a new one is
fairly straightforward.http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
has detailed information about the platform.
Other noteworthy updates:
- Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain
Lemieux are now maintaining the platform.This is an older ARM9 based platform from NXP (not Freescale), but
it remains in use in embedded markets.- Kevin Hilman is now co-maintaining the Amlogic Meson platform for
both 32-bit and 64-bit ARM, and started contributing some patches.- As is often the case, work on the OMAP platforms makes up the bulk
of the actual SoC code changes in arch/arm, but there isn't a lot
of that either"* tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits)

The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2
interrupt controllers.This is a list of new features in comparison to the legacy driver:
* irq types are taken from device tree settings, no more need to
hardcode them,
* old driver is based on irq_domain_add_legacy, which causes problems
with handling MIC hardware interrupt 0 produced by SIC1,
* there is one driver for MIC, SIC1 and SIC2, no more need to handle
them separately, e.g. have two separate handlers for SIC1 and SIC2,
* the driver does not have any dependencies on hardcoded register
offsets,
* the driver is much simpler for maintenance,
* SPARSE_IRQS option is supported.Legacy LPC32xx interrupt controller driver was broken since commit
76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler"), which
requires a private interrupt handler, otherwise any SIC1 generated
interrupt (mapped to MIC hwirq 0) breaks the kernel with the message
"unexpected IRQ trap at vector 00".The change disables compilation of a legacy driver found at
arch/arm/mach-lpc32xx/irq.c, the file will be removed in a separate
commit.Fixes: 76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler")

The change switches NXP LPC32xx platforms to LPC32xx clock driver
powered by common clock framework, this obsoletes mach-lpc32xx/clock.o
legacy clock driver and thus it is removed.Legacy timer driver mach-lpc32xx/timer.o strictly depends on legacy
clock support, but fortunately an existing LPC32xx clock source and
clock event driver completely replaces it, and thus it can be removed
as well.Noticeably platform UART driver directly operates on LPC32xx source
control block registers, remove this dependency to avoid overlapping
with common clock framework driver, also this guarantees that UART is
working expectedly.Tested-by: Sylvain Lemieux

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOENFor IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.Signed-off-by: Rob Herring

Migrate lpc32xx driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.Cc: Roland Stigge
