Instead of passing GPIO numbers pertaining to ourselves through
platform data, just request GPIO descriptors from our own GPIO
chips and use them, and cut down on the unnecessary complexity.

There are a number of old Makefile.boot files that remain from the
multiplatform conversion, and three that are still in use.
These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values
that are platform specific. It turns out that we can generally just
derive this from information that is available elsewhere:
- ZRELADDR is normally detected at runtime with the
CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to
for 'make uImage'. In a multiplatform kernel, one always has
to pass this as the $(LOADADDR) variable, but in the StrongARM
kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET)
and $(TEXT_OFFSET) that are already known.
- PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which
in turn is only used for the pre-ATAGS 'param_struct' based boot
interface on StrongARM based machines with old boot loaders.
They can both be derived from CONFIG_PHYS_OFFSET and a machine
specific offset for the initrd, so all of the logic for these
can be part of arch/arm/boot/bootp/Makefile.

Legacy board files with no known users are planned to get removed in
early 2023, and this covers the majority of the omap1 boards as well.
According to Tony, the actual users are all on OSK, Nokia770, and
AMS-Delta. Additionally, the sx1 and palmte boards are supported by qemu,
which is convenient for testing, so all five stay around past the initial
board removal.
As omap1 is now part of the multiplatform build and uses the common-clk
framework, it has become easier to convert these to use devicetree
based booting in the future.

There are a total of eight platforms that only suppor ATAGS based boot
with board files but no devicetree booting.
For dove, the DT support is part of the mvebu platform, which shares
driver but no code in arch/arm.
Most of these will never get converted to DT, and the majority of the
board files appear to be entirely unused already. There are still known
users on a few machines, and there may be interest in converting some
omap1, ep93xx or footbridge machines over in the future.
For the moment, just add a Kconfig dependency to hide these platforms
completely when CONFIG_ATAGS is disabled, and reorder the priority
of the options: Rather than offering to turn ATAGS off for platforms
that have DT support, make it a top-level setting that determines
which platforms are visible.
The s3c24xx platform supports one machine with DT support, but it
cannot be built without also including ATAGS support, and the
entire platform is scheduled for removal, so leaving the entire
platform behind a dependency seems good enough.
All defconfig files should keep working, as the option remains default
enabled.

OMAP1 still uses its own implementation of standard clock API defined in
include/linux/clk.h. Internals of that implementation are not visible
outside OMAP1 directory. As a consequence, device drivers are not able to
register clocks potentially provided by peripheral devices.
Drop OMAP1 implementation of the clock API and enable common clock
framework. Modify the remaining low level code to be compatible with
clock provider API and register the clocks with CCF.
Move initialisation of clocks to omap1_timer_init() to avoid memory
allocation issues at early setup phase from where omap1_init_early() is
called. Register the clocks after initialization of clock I/O registers,
local clock pointers used by OMAP1 clock ops, and local .rate fields of
clocks with no local implementation of .recalc ops, so CCF structures are
populated with correct data during clock registration. Instead of
enabling some of the registered clocks, flag them for CCF as critical.
Introduce .is_enabled op using code that verifies hardware status of clock
enablement, split out from implementation of .disable_unused op, so the
latter is actually called by CCF for not requested but hardware enabled
clocks. Add .round_rate ops where missing so .set_rate ops are called by
CCF as expected. Since CCF allows parallel execution of .enable/.disable
and .set_rate ops, protect registers shared among those groups of ops from
concurrent access with spinlocks. Drop local debugfs support in favor of
that provided by CCF.

One of my multiplatform patches went a little too far and removed
a declaration that is needed for compile-testing the omapfb
driver on non-OMAP1 platforms:

omapfb is disabled, like we do for the usb specific bits.

Commit ef772f2ee31e ("ARM: OMAP: Fix CONFIG_DEBUG_LL") was supposed to fix
low level debugging, most possibly by early enabling UART clocks. The fix
actually introduced early reset of most bits of MOD_CONF_CTRL_0 register,
with the exception of UART1 and UART2 clock related bits which were set
high. However, UART1 clock bit can play different roles on different
OMAP1 variants. On OMAP1610 it enables the clock as intended, but on
OMAP1510 it switches the clock rate from 12 to 48 MHz. Even worth, for
UART2 the bit changes its clock rate also on OMAP1610. As a result, UART
rates set by a bootloader can be unintentionally changed early on kernel
boot and low level debugging broken, not fixed. Besides, reset of all
other bits was not justified.
Don't touch register bits not related to UART clocks. Also, don't touch
the bit of UART2 clock. Make sure UART1 and UART3 are enabled early on
relevant OMAP1610 machine types while preserving bootloader UART clock
rates on others.

In a multiplatform randconfig kernel, one can have
CONFIG_ARCH_OMAP1 enabled, but none of the specific SoCs.
This leads to some build issues as the code is not
meant to deal with this configuration at the moment:
arch/arm/mach-omap1/io.c:86:20: error: unused function 'omap1_map_common_io' [-Werror,-Wunused-function]
arch/arm/mach-omap1/pm.h:113:2: error: "Power management for this processor not implemented yet" [-Werror,-W#warnings]
Use the same trick as on OMAP2 and guard the actual compilation
of platform code with another Makefile ifdef check based
on an option that depends on having at least one SoC enabled.
The io.c file still needs to get compiled to allow building
device drivers with a dependency on CONFIG_ARCH_OMAP1.

and it would be good to completely get rid of these in favor
of passing information through platform devices and the pinctrl
subsystem.
However, given that nobody is working on that, just move it
one step forward by splitting out the header files that are
used by drivers today from the machine headers that are only
used internally.

The register definitions in this header are used in at least four
different places, with little hope of completely cleaning that up.
Split up the file into a portion that becomes a linux-wide header
under include/linux/soc/ti/, and the parts that are actually only
needed by board files.

To avoid relying on the mach/irqs.h header, stop using
OMAP_LCDC_IRQ and INT_1610_SoSSI_MATCH directly in the driver
code, but instead pass these as resources.

The omapfb driver is split into platform specific code for omap1, and
driver code that is also specific to omap1.
Moving both parts into the driver directory simplifies the structure
and avoids the dependency on certain omap machine header files.
As mach/lcd_dma.h can not be included from include/linux/omap-dma.h
any more now, move the omap_lcd_dma_running() declaration into the
omap-dma header, which matches where it is defined.

Pull irq updates from Thomas Gleixner:
"Updates for the interrupt subsystem:
Core changes:
- Prevent a potential deadlock when initial priority is assigned to a
newly created interrupt thread. A recent change to plug a race
between cpuset and __sched_setscheduler() introduced a new lock
dependency which is now triggered. Break the lock dependency chain
by moving the priority assignment to the thread function.
- A couple of small updates to make the irq core RT safe.
- Confine the irq_cpu_online/offline() API to the only left unfixable
user Cavium Octeon so that it does not grow new usage.
- A small documentation update
Driver changes:
- A large cross architecture rework to move irq_enter/exit() into the
architecture code to make addressing the NOHZ_FULL/RCU issues
simpler.
- The obligatory new irq chip driver for Microchip EIC
- Modularize a few irq chip drivers
- Expand usage of devm_*() helpers throughout the driver code
- The usual small fixes and improvements all over the place"

Now that entry code handles IRQ entry (including setting the IRQ regs)
before calling irqchip code, irqchip code can safely call
generic_handle_domain_irq(), and there's no functional reason for it to
call handle_domain_irq().
Let's cement this split of responsibility and remove handle_domain_irq()
entirely, updating irqchip drivers to call generic_handle_domain_irq().
For consistency, handle_domain_nmi() is similarly removed and replaced
with a generic_handle_domain_nmi() function which also does not perform
any entry logic.
Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire
when they were called in an inappropriate context. So that we can
identify similar issues going forward, similar WARN_ON_ONCE() logic is
added to the generic_handle_*() functions, and comments are updated for
clarity and consistency.

Commit 38225f2ef2f4 ("ARM/omap1: switch to use dma_direct_set_offset for
lbus DMA offsets") removed a lot of mach/memory.h, but left the USB
offset handling split into arch/arm/mach-omap1/usb.c and
drivers/usb/host/ohci-omap.c.
This can cause a randconfig build warning that now fails the build
with -Werror:
