21a3e6eed4 ARM: omap1: remove osk-mistral add-on board support
As Aaro Koskinen points out, nobody should have this one any more,
and I noticed the code is rather ugly, so let's removed it but
keep the rest of the OSK support that is still used.

0d7bb85e94 ARM: omap1: remove unused board files
All board support that was marked as 'unused' earlier can
now be removed, leaving the five machines that that still
had someone using them in 2022, or that are supported in
qemu.

980a637d11 ARM: omap1: fix !ARCH_OMAP1_ANY link failures
While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like

ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':
drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority'
ld: drivers/dma/ti/omap-dma.o: in function `omap_dma_free_chan_resources':

drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status'

I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like

arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]

As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

4a69c8b7fe ARM: omap1: add Kconfig dependencies for unused boards
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.

96a4ce30c2 ARM: add ATAGS dependencies to non-DT platforms
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.

615dce5bf7 ARM: omap1: fix build with no SoC selected
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.

b1b3f49ce4 ARM: config: sort select statements alphanumerically
As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,

ac2885df30 ARM: OMAP1: ams-delta: set up regulator over modem reset GPIO pin
The Amstrad Delta on-board latch2 bit named MODEM_NRESET, now available
as a GPIO pin AMS_DELTA_GPIO_PIN_NMODEM_RESET, is used to power up/down
(bring into/out of a reset state) two distinct on-board devices
simultaneously: the modem, and the voice codec. As a consequence, that
bit is, or can be, manipulated concurrently by two drivers, or their
platform provided hooks.

Instead of updating those drivers to use the gpiolib API as a new method
of controlling the MODEM_NRESET pin state, like it was done to other
drivers accessing latch2 pins, and still being vulnerable to potential
concurrency conflicts, or trying to solve that sharing issue with a
custom piece of code, set up a fixed regulator device on top of that
GPIO pin, with the intention of updating both drivers to manipulate that
regulator, not the GPIO pin directly.

Before the ASoC driver is updated and the modem platform data expanded
with a power management callback for switching its power, the
ams_delta_latch_write() function, which still provides the old API for
accessing latch2 functionality from not updated drivers, is modified to
toggle the regulator instead of the MODEM_NRESET GPIO pin.  A helper
function provided for balancing the regulator enable/disable operations,
together with the consumer data needed for tracking the regulator state,
will be removed once the drivers are updated.

Depends on patch series "ARM: OMAP1: ams-delta: replace custom I/O with
GPIO".

937eb4bb00 ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpio
Once ready, ams-delta specific device drivers currently calling custom
ams_delta_latch[12]_write() functions can be updated to call generic
gpio_set_value() instead, which will make them less platform dependent.
Even more, some custom ams-delta only drivers can perhaps be dropped
from the tree after converting selected ams-delta platform devices to
follow generic GPIO based device models.

The latch_gpios[] table is initially filled with all latch1 and latch2
GPIO pins in order to register and initialize them from the board file
until those are handled by respective existing device drivers (leds,
nand, lcd, serio, asoc, serial). That table will get almost empty after
the transision process is completed, holding only pins not used by any
drivers / connected to unused devices, in order to initialize them from
the board file for power saving purposes.

The new ams_delta_latch_write() function is a unified replacement for
those removed ams_delta_latch[12]_write(), and serves as a temporary
wrapper over gpio_set_value(), providing the old API for those not yet
updated device drivers, and will be removed after all custom drivers are
converted or replaced.

For still better multi-OMAP1 support, expand omap1_rate_table with flags

idea is stolen from current omap24xx clock rate selection algorithm.

Since clkdev platform flag definitions are reused here, those had to be
expanded with one extra entry for OMAP1710 subtype, as this is the only
SoC for which we allow selection of the highest, 216 MHz rate.

Once done, remove no longer needed clock rate configure time options.

e9b7086b80 ARM: OMAP: Fix reprogramming of dpll1 rate
Commit a66cb3454f220f49f900646ebdc76cb943319eb7 (ARM: OMAP: Map SRAM
later on with ioremap_exec()) moved the SRAM init to happen later
to remove a dependency to early SoC detection for map_io.

This broke booting on some boards not using Kconfig option for
OMAP_CLOCKS_SET_BY_BOOTLOADER as the dpll1 reprogramming would
cause the following error:

Fix this by adding omap1_clk_late_init() that only reprograms dpll1
if the bootloader rate is less than 60MHz. This also allows removing
of the OMAP_CLOCKS_SET_BY_BOOTLOADER option.

9632f9890e OMAP1: drop AMS_DELTA_FIQ config option
This patches removes a config option that was used to select a FIQ
handler to be build for Amstrad Delta, as required by the on-board serio
interface driver. Not having any problem reports received since it was
introduced in 2.6.35, the FIQ handler can now be built and initialized by
default, thus reqiring no extra config option.

936305a96c OMAP1: OPP: add KConfig entry for 96MHz ARM rate (using a 12MHz oscillator)
Add KConfig entry for one of the OMAP1 DVFS rates that was missing it.
Based on the surrounding rate KConfigs and the oscillator frequency,
this patch marks it as valid for all OMAP1 platforms -- Richard,
Tuukka, Tony, perhaps you can comment if this does not look right?

In the long term, all of these CONFIG_OMAP_ARM_*MHZ should be removed.
The OPP settings should be associated with the platform information in
the structure data (perhaps by extending the omap_chip defines).  The
selection of which rates to use should be handled at runtime; rates
that are impossible due to xtal frequency mismatch or SoC-type
mismatch should not be included.  If implemented correctly, this
should save some CPU time and some memory on OMAP1 kernels.

60c3bf3f12 OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt processing
This patch introduces a Fast Interrupt Request (FIQ) handler for Amstrad Delta
(E3) videophone. The handler's purpose is to process interrupts generated by a
GPIO line that a serial keyboard clock hangs off. It collects consecutive bits
into words, pushing them into a buffer, then requests a higher level interrupt
after one or more words are ready for further processing by a keyboard port
driver.

The handler also processes interrupts generated by two other GPIO lines, used
by other on-board supported devices, by simply requesting a higher level
interrupt, that in turn should invoke those device's specific irq handlers.

IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been
choosen as a higher level interrupt source.

45f780a061 omap1: omap_udc: Add clocking and disable vbus sense for omap7xx
The l3_ocpi_ck clock is needed on omap7xx processors for USB.
Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for
the usb_dc_ck on omap7xx, which is a different bit than that
of the omap16xx-defined clock of the same name.

I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as
dc_clk and hhc_clk, respectively, for omap7xx CPUs.  Additionally,
I added a check in machine_without_vbus_sense for all omap7xx
devices, as presently I know of no omap7xx-based devices that
have vbus sense, and it made more sense to me to use a cpu check
here than to spell out each machine one at a time.  Finally, DMA
is disabled for omap7xx, as it causes problems with these chips.
