56882dc4cb Convert CONFIG_USB_EHCI_IS_TDI to Kconfig
On mvebu this is defined if and only if !ARM64.

Otherwise it is defined for boards with ARCH_MX23, ARCH_TEGRA and
ARCH_ZYNQ, and also for SOC_AR934X (tplink_wdr4300).

35839eda8b pytest: Show a message when sandbox crashes
When a test hands on a real board there is no way on the console to obtain
any information about why it hung.

With sandbox we can actually find out that it died and get a signal or
exit code. Add this to make it easier to figure out what happened.

So instead of:

test/py/u_boot_spawn.py:171: in expect
    c = os.read(self.fd, 1024).decode(errors='replace')
E   OSError: [Errno 5] Input/output error

We get:

test/py/u_boot_spawn.py:171: in expect
    c = os.read(self.fd, 1024).decode(errors='replace')
E   ValueError: U-Boot exited with signal 11 (Signals.SIGSEGV)

07c652400d rtc: ds1307: Handle oscillator-stop bit correctly
The DS1307 driver was originally based on the DS1337 driver. However,
the functionality of the clock set/get functions has diverged. In the
original DS1337 driver, the set/get functions did the following:
  1) Setting the clock ensured the oscillator was enabled.
  2) Getting the clock checked and reset the oscillator-stop flag.
The DS1307 does not have an oscillator-stop flag, but the driver tried
(incorrectly) to emulate this by ensuring the oscillator was running. It
really makes no sense to start a stopped clock without setting it.

This patch makes the DS1307 driver behave like the original DS1337
driver again. For the DS1307 itself, this is just a removal of code,
since there is no oscillator-fail bit to check or reset, and the clock
is started when it is set. Since the DS1307 driver can now also be used
for the DS1337 and DS1340 which do have this bit, add code to handle the
oscillator-stop bit in the same was the original DS1337 driver did --
i.e. report that the oscillator had stopped and clear the flag.

This means that setting the date using the date command (which does both
a get and a set) will now clear the oscillator-stop flag in addition to
setting and starting the clock.

The old-style (non-DM) code has not been updated and will be removed in
a future patch. Note that this older code does not support the DS1337,
as there is a separate driver for this. Also note that the original (DM)
code used the wrong control-register address for the DS1337.

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.

Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.

Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).

2421497cb7 sunxi: video: Convert panel I2C to use DM_I2C
Two displays supported by the sunxi display driver (each one used by a
single board) require initialization over I2C. Both previously used
i2c_soft; replace this with the i2c-gpio instance that already exists in
those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus).

Since the i2c-gpio nodes are not referenced by any other node in the
device trees (the device trees have no panel node), the I2C bus is
selected by its node name.

This panel initialization code was the only i2c_soft user, so the
i2c_soft GPIO setup code can be removed now as well.

8b0eacdf2b sunxi: pmic_bus: Use the DM PMIC interface when possible
The pmic_bus functions are used in both SPL (for regulator setup) and
U-Boot proper (for regulator setup, SID access, GPIO, and poweroff).

Currently, pmic_bus conflicts with DM_I2C because it uses the legacy I2C
interface. This commit makes pmic_bus dual-compatible with either the
legacy I2C functions or the newly-added PMIC_AXP driver (which uses
DM_I2C). In turn, this allows platforms to start transitioning to DM_I2C
in U-Boot proper, without breaking boards that still depend on the
legacy I2C interface for other reasons.

d3b02987cb sunxi: pmic_bus: Clean up preprocessor conditions
Instead of using the SoC symbols to decide the bus type, use whichever
bus driver is actually enabled. This allows collapsing all of the AXP2xx
and AXP8xx variants into one "else" case. It also has the advantage of
falling back to I2C when the other bus drivers are disabled; this works
because all of the PMICs support I2C in addition to other interfaces.

3227c85fe7 i2c: Add a DM_I2C driver for the sun8i RSB controller
This bus controller is used to communicate with an X-Powers AXP PMIC.
Currently, various drivers access PMIC registers through a platform-
specific non-DM "pmic_bus" interface, which depends on the legacy I2C
framework. In order to convert those drivers to use DM_PMIC, this bus
needs a DM_I2C driver.

Refactor the rsb functions to take the base address as a parameter,
and implement both the existing interface (which is still needed in
SPL) and the DM_I2C interface on top of them.

The register for switching between I2C/P2WI/RSB mode is the same across
all PMIC variants, so move that to the common header.

There are only a couple of pairs of hardware/runtime addresses used
across all PMIC variants. So far the code expected only the "primary"
pair, but some PMICs like the AXP305 and AXP805 use the secondary pair,
so add support for that to the DM driver as well.

4ab39e74b6 sunxi: pmic_bus: Fix Kconfig dependencies
AXP_PMIC_BUS enables communication with a specific AXP PMIC at a
PMIC-dependent I2C/P2WI/RSB bus address. It is automatically selected
as a dependency of the PMIC driver. It should not be selectable by the
user when no PMIC is chosen.

AXP_GPIO uses the pmic_bus functions, and also depends on a specific
PMIC header to pick up register definitions.

Both of these changes have no impact on any existing configs, since
the code does not compile if the dependencies are not met.

abd2e783f1 sunxi: Select SUN8I_RSB more carefully
SUN8I_RSB should not be selected by MACH_SUN8I, because the hardware
is not present in half of those SoCs (H3/H5, R40, and V3s). Move the
selection to the SoCs where the hardware actually exists.
As it currently stands, selecting that option also requires using it in
some way, which is not the case for one A80 board. Since we have only
three A80 boards in total, we select it their via their defconfigs.

ea261fdeb2 sunxi: Only initialize legacy I2C when enabled
CONFIG_SPL_I2C is the wrong symbol to use here. It is the top-level
Kconfig symbol (not specific to either legacy or DM I2C), whereas the
i2c_init() function is specific to legacy I2C. This change fixes a
build failure when enabling SPL_I2C but not SPL_SYS_I2C_LEGACY.
