Now that the PMIC has a DM driver and binds device tree subnodes, the
GPIO device can be bound that way, instead of from inside board code.
Since the driver still uses the single set of register definitions from
axpXXX.h (as selected by AXPxxx_POWER), it does not differentiate among
the supported compatibles.

These PMICs each have two GPIO pins, and are supported by the axp_gpio
driver. In order to convert the axp_gpio driver to probe using the
device tree, the corresponding device tree nodes must be present. Add
them, following the same binding as the AXP209 and AXP813.

Now that the sunxi_gpio driver handles pull-up/down via the driver
model, we can switch to DM_GPIO for these pins with no loss in

the device tree, we can remove the Kconfig symbols.

Now that issues with the BROM have been sorted out, we can implement
PSCI system suspend on H3 by delegating to SCP firmware. Let's start by
including the firmware in the FIT image and starting the coprocessor if
valid firmware is loaded.
Signed-off-by: Samuel Holland <samuel@sholland.org>
Due to a bug in the H3 SoC, where the CPU 0 hotplug flag cannot be
written, resuming CPU 0 requires using the "Super Standby" code path in
the BROM instead of the hotplug path. This path requires jumping to an
eGON image in SRAM.
Add support to the build system to generate this eGON image and include
it in the FIT, and add code to direct the BROM to its location in SRAM.
Since the Super Standby code path in the BROM initializes the CPU and
AHB1 clocks to 24 MHz, those registers need to be restored after control
passes back to U-Boot. Furthermore, because the BROM lowers the AHB1
clock divider to /1 before switching to the lower-frequency parent,
PLL_PERIPH0 must be bypassed to prevent AHB1 from temporarily running at
600 MHz. Otherwise, this locks up the SoC.

Do not try to send an SGI from CPU 0 to itself. Since FIQs are masked
when entering monitor mode, this will hang. Plus, CPU 0 cannot fully
power itself off anyway. Instead, have it turn FIQs back on and continue
servicing SGIs from other cores.

Now that Crust (SCP firmware) has support for H3, we need a FIT image to
load it. H3 also needs to load a SoC-specific eGon blob to support CPU 0
hotplug. Let's first enable FIT support before adding extra firmware.
Update the binman description to work on either 32-bit or 64-bit SoCs:
- Make BL31 optional, since it is not used on 32-bit SoCs (though BL32
may be used in the future).
- Explicitly set the minimum offset of the FIT to 32 KiB, since SPL on
some boards is still only 24 KiB large even with FIT support enabled.
CONFIG_SPL_PAD_TO cannot be used because it is not defined for H616.
FIT unlocks more features (signatures, multiple DTBs, etc.), so enable
it by default. A10 (sun4i) only has 24 KiB of SRAM A1, so it needs
SPL_FIT_IMAGE_TINY. For simplicity, enable that option everywhere.
Cover-letter:
sunxi: SPL FIT support for 32-bit sunxi SoCs
This series makes the necessary changes so 32-bit sunxi SoCs can load
additional device trees or firmware from SPL along with U-Boot proper.
There was no existing binman entry property that put the FIT at the
right offset. The minimum offset is 32k, but this matches neither the
SPL size (which is no more than 24k on some SoCs) nor the FIT alignment
(which is 512 bytes in practice due to SPL size constraints). So instead
of adding a new property, I fixed what is arguably a bug in the offset
property -- though this strategy will not work if someone is
intentionally creating overlapping entries.

Signed-off-by: Samuel Holland <samuel@sholland.org>
The bulk of it is (finally!) some DT sync from the kernel. We refrained
from syncing one incompatible change, as this would spoil booting Linux
kernels before v5.13 with U-Boot's DT (via UEFI, for instance).
I test booted Linux v5.18 and v5.4 with that new DT on some boards, and
the headless peripherals (MMC, USB, Ethernet) seemed to work.
The rest are fixes:
- silencing missing clock warnings due to the new pinctrl driver
- fixing "UART0 on PortF", allowing UART access through the SD card pins
- add an F1C100s clock driver, to enable MMC support (SPI comes later)
- some cleanups for CONS_INDEX_n in Kconfig
Tested on BananaPi-M1, Pine64-LTS, Pine-H64, X96-Mate (H616) and
OrangePi-Zero.
ARCH_SUNXI selects DM_SERIAL, so the condition can never be satisfied.

When CONFIG_UART0_PORT_F is defined, we try to configure two PortF pins
(usually used for the SD card) as UART0. Some SoCs use the mux value of
3 for this, while others use 4.
The combination of Kconfig symbols we currently use was not quite right:
we mis-configure the A31, A64, H6 and H616.
Going through the list in the pinctrl driver, there are only a few older
SoCs that use a value of 4, so revert the #ifdef clause, and name those
explicitly, instead of the other way around.

The initial U-Boot F1C100s port was based on the mainline kernel DT
files, which were quite basic and were missing the essential MMC and
SPI peripherals. While we could work around this in the SPL by
hardcoding the required information, this left U-Boot proper without SD
card or SPI flash support, so actual loading would require FEL boot.
Now the missing DT bits have been submitted and accepted in the kernel
tree, so lets sync back those files into U-Boot to enable MMC and
SPI, plus benefit from some fixes.
