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)Signed-off-by: Klaus H. Sorensen

U-Boot is having DT which doesn't cover all options currently supported by
driver. DT binding is aligned with Linux kernel version available here.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ti,dp83867.txt
Based on my talk with Grygorii Strashko better will be to remove it.Also Linux kernel bindings are being converted to yaml that's another

ACPI GPEs are used to signal interrupts from peripherals that are accessed
via ACPI. In U-Boot these are modelled as interrupts using a separate
interrupt controller. Configuration is via the device tree.Add a simple driver for this.

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.

pinctrl device.Signed-off-by: Simon Glass

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).Signed-off-by: Simon Glass

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.Signed-off-by: Simon Glass

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

This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers based on driver model. There are two
reasons to have a separate driver rather than including it inside
the MAC driver itself:
*) The MDIO interface is shared by all Ethernet ports, so a driver
must guarantee non-concurrent accesses to this MDIO interface. The
most logical way is to have a separate driver that handles this
single MDIO interface, used by all Ethernet ports.
*) The MDIO interface is the same between the existing mv643xx_eth
driver and the new mvneta/mvpp2 driver. Even though it is for now
only used by the mvneta/mvpp2 driver, it will in the future be
used by the mv643xx_eth driver as well.This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE
802.3 Clause 45.This patch also adds device tree binding for marvell MDIO driver.

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.In both cases, there are no DT blobs that contain the old strings.
So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A. More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.Fixes: 69a00875e3db ("doc: dt-bindings: Describe Freescale TSEC ethernet controller")
