b0dcc87106 dm: core: Read parent ofdata before children
At present a device can read its ofdata before its parent has done the
same. This can cause problems in the case where the parent has a 'ranges'
property, thus affecting the operation of dev_read_addr(), for example.

We already probe parent devices before children so it does not seem to be
a large step to do the same with ofdata.

Make the change and update the documentation in this area.

befadde0a2 log: syslog driver
Provide a log driver that broadcasts RFC 3164 messages to syslog servers.
rsyslog is one implementation of such a server.

The messages are sent to the local broadcast address 255.255.255.255 on
port 514.

The environment variable log_hostname can be used to provide the HOSTNAME
field for the messages. The optional TIMESTAMP field of RFC 3164 is not
provided.

42c64d1bc9 sandbox: Update PCI nodes in dts files
The way the PCI nodes are written today causes a number of warnings if
we stop disabling some of the warnings we pass to DTC.  As these
warnings aren't disabled in current Linux Kernel builds, we should aim
to not disable them here either, so rewrite these slightly.  Update the
driver model doc as well.

3fb22bc2f8 gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.

This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.

Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.

It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

9368bdfebd ram: stm32mp1: the property st, phy-cal becomes optional
This parameter "st,phy-cal" becomes optional and when it is
absent the built-in PHY calibration is done.

It is the case in the helper dtsi file "stm32mp15-ddr.dtsi"
except if DDR_PHY_CAL_SKIP is defined.

This patch also impact the ddr interactive mode
- the registers of the param 'phy.cal' are initialized to 0 when
  "st,phy-cal" is not present in device tree (default behavior when
  DDR_PHY_CAL_SKIP is not activated)
- the info 'cal' field can be use to change the calibration behavior
  - cal=1 => use param phy.cal to initialize the PHY, built-in training
             is skipped
  - cal=0 => param phy.cal is absent, built-in training is used (default)

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

ba6fb2f6ac dm: i2c-gpio: add support for clock stretching
This adds support for clock stretching to the i2c-gpio driver. This is
accomplished by switching the GPIO used for the SCL line to an input
when it should be driven high, and polling on the SCL line value until
it goes high (indicating that the I2C slave is no longer pulling it
low).

This is enabled by default; for gpios which cannot be configured as
inputs, the i2c-gpio,scl-output-only property can be used to fall back
to the previous behavior.

21e4ee3c9c doc: net: Rewrite network driver documentation
doc/README.drivers.eth seems like a good source for understanding
U-Boot's network subsystem, but is only talking about legacy network
drivers. This is particularly sad as proper documentation would help in
porting drivers over to the driver model.

Rewrite the document to describe network drivers in the new driver model
world. Most driver callbacks/methods are almost identical in their
semantic, but recv() differs in some important details.

Also keep some parts of the original text at the end, to help
understanding old drivers. Add some hints on how to port drivers over.

This also uses the opportunity to reformat the document in reST, on the
way moving it into doc/driver-model and adding it into the structure
there.

025543554c dm: irq: Add support for requesting interrupts
At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.

Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.

U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.

Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.

Add a simple test of the new functionality.

98a8f445fd dfu: Add optional timeout parameter
When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.

This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.

The patch is based on the commit
5e966ccc3c
by Sebastien Colleur, which has been heavily reworked due to U-Boot changes
in the past.

74749f1e84 x86: Add a generic Intel pinctrl driver
Recent Intel SoCs share a pinctrl mechanism with many common elements. Add
an implementation of this core functionality, allowing SoC-specific
drivers to avoid adding common code.

As well as a pinctrl driver this provides a GPIO driver based on the same
code.

Once other SoCs use this driver we may consider moving more properties to
the device tree (e.g. the community info and pad definitions).

2206ac248a dm: pci: Allow delaying auto-config until after relocation
At present PCI auto-configuration happens in U-Boot both before and after
relocation. This is a waste of time and may mess up static addresses used
in board_init_f(). Adjust the code to supporting doing auto-configuration
once, after relocation, under control of a device-tree property.

This is needed for Apollo Lake for debugging the silicon-init code. Once
the UART is moved to a different MMIO address the debug UART does not work
and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.

Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation
for disabling clock output") of mainline linux kernel.

The clock output is generally only used for testing and development and not
used to daisy-chain PHYs.  It's just a source of RF noise afterward.

Add a mux value for "off".  I've added it as another enumeration to the
output property.  In the actual PHY, the mux and the output enable are
independently controllable.  However, it doesn't seem useful to be able
to describe the mux setting when the output is disabled.

Document that PHY's default setting will be left as is if the property
is omitted.

e6661cf767 ubi: Add "skipcheck" command to set/clear this bit in the UBI volume hdr
U-Boot now supports the "skip_check" flag to optionally skip the CRC
check at open time. Currently its only possible to set this bit upon
UBI volume creation. But it might be very useful to also set this bit
on already installed systems (e.g. field upgrade) to make also use of
the boot-time decrease on those systems.

This patch now adds a new "ubi" command "ubi skipcheck" to set or clear
this bit in the UBI volume header:

=> ubi skipcheck rootfs0 on
Setting skip_check on volume rootfs0

BTW: This saves approx. 10 seconds Linux bootup time on a MT7688 based
target with 128MiB of SPI NAND.

471c2d5e22 dt-bindings: remoteproc: Add bindings for R5F subsystem on TI K3 SoCs
The Texas Instruments K3 family of SoCs have one of more dual-core
Arm Cortex R5F processor subsystems/clusters (R5FSS). Add the device
tree bindings document for these R5F subsystem devices. These R5F
processors do not have an MMU, and so require fixed memory carveout
regions matching the firmware image addresses. The nodes require more
than one memory region, with the first memory region used for DMA
allocations at runtime. The remaining memory regions are reserved
and are used for the loading and running of the R5F remote processors.

The added example illustrates the DT nodes for the single R5FSS device
present on K3 AM65x family of SoCs.

9b69ba4a78 pci: sandbox: Move the emulators into their own node
Sandbox pci works using emulation drivers which are currently children of
the pci device:

	pci-controller {
		pci@1f,0 {
			compatible = "pci-generic";
			reg = <0xf800 0 0 0 0>;
			emul@1f,0 {
				compatible = "sandbox,swap-case";
			};
		};
	};

In this case the emulation device is attached to pci device on address
f800 (device 1f, function 0) and provides the swap-case functionality.

However this is not ideal, since every device on a PCI bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.

Worse, child devices cannot be probed before their parents. This forces
us to use 'find' rather than 'get' to obtain the emulator device. In fact
the emulator devices are never probed. There is code in
sandbox_pci_emul_post_probe() which tries to track when emulators are
active, but at present this does not work.

A better approach seems to be to add a separate node elsewhere in the
device tree, an 'emulation parent'. This could be given a bogus address
(such as -1) to hide the emulators away from the 'pci' command, but it
seems better to keep it at the root node to avoid such hacks.

Then we can use a phandle to point from the device to the correct
emulator, and only on sandbox. The code to find an emulator does not
interfere with normal pci operation.

Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. Update the existing
device trees and the code for finding an emulator.

This brings PCI emulators more into line with I2C.

U-Boot already supports using -D to indicate that it should use the normal
device tree. It is sometimes useful to run with the test device tree, e.g.
when running a test. Add a -T option for this along with some
documentation.

It can be used like this:

   /tmp/b/sandbox/u-boot -T -c "ut dm pci_busdev"

(this will use /tmp/b/sandbox/arch/sandbox/dts/test.dtb as the DT)
