This series implements various improvements to Linux header
compatibility, largely in preparation for a full port of Linux CCF but
many of these changes would also be helpful when porting other drivers.
Beside the basic header/compat stuff there are a few larger patches:
Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the
same as it does in Linux printing the name of the ofnode, but notably it
expects an ofnode pointer rather than a device_node.
Patch 2 adds an option to skip doing a full DM scan pre-relocation.
Some platforms like Qualcomm don't actually need devices to be probed
prior to relocation, it is also quite slow to scan the entire FDT before
caches are up. This option gets us to main loop 30-50% faster.
Unfortunately it isn't possible to totally skip DM since U-Boot will
panic if it can't find a serial port, but the serial uclass code will
bind the serial port itself by reading /chosen/stdout-path, however any
dependencies like clocks won't be found so this should only be enabled
if the serial driver gracefully handles missing clocks.
Patch 3 adds [k]strdup_const(), this works the same as the Linux version
saving a small amount of memory by avoiding duplicating strings stored
in .rodata, this is particularly useful for CCF.
Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions,
making it possible to parse 64-bit arrays.
Patch 6 provides a simple implementation of kref, this will be used
by CCF.
Patch 9 adds devm_krealloc() support to devres, it relies on storing
allocation sizes in the devres struct which will add a small overhead.

These are similar to their Linux counterparts, adding helpers
for reading arrays of 64-bit values with of_access and fdtdec
implementations.

The refactoring in commit 00d0ff7f81 ("clk: mediatek: refactor parent
rate lookup functions") introduced a regression where fixed PLL clocks
using mtk_clk_fixed_pll_ops are not properly recognized as valid parents
in the CLK_PARENT_APMIXED case.
Fixed PLL clocks are implemented using mtk_clk_fixed_pll_ops instead of
mtk_clk_apmixedsys_ops, but they can also serve as parent clocks in the
APMIXED domain. The parent lookup function needs to check for both
driver ops to properly resolve the parent clock device.
Add mtk_clk_fixed_pll_ops checks alongside mtk_clk_apmixedsys_ops checks
in mtk_find_parent_rate() to restore support for fixed PLL parent clocks.

In dwc3_free_one_event_buffer(), only the DMA buffer (evt->buf) was
being freed via dma_free_coherent(), but the evt structure itself was
never explicitly freed, causing a memory leak.
In dwc3_free_event_buffers(), the ev_buffs pointer array allocated
with memalign() was never freed after iterating and releasing all
individual event buffers, causing another memory leak.
Fix both leaks by freeing the evt struct in
dwc3_free_one_event_buffer() and freeing dwc->ev_buffs in
dwc3_free_event_buffers() after all entries have been released.

Enable automatic allocation of platform data for the Cadence XSPI
controller by setting .plat_auto.
Without this, dev_get_plat() may return invalid or uninitialized
platform data when multiple XSPI controllers are present, leading
to incorrect IOBASE/SDMABASE/AUXBASE values and causing SPI flash
probe failures.
Setting .plat_auto ensures each controller instance receives a
properly sized cdns_xspi_plat structure, allowing SF probe to work
correctly.

The process through which the MC firmware parses the DPL and initializes
all the requested DPAA2 objects is a complex one which can take quite a
bit of time. For the those circumstances in which a fast boot is
required on DPAA2 based SoCs, add the 'nowait' optional parameter for
the fsl_mc [lazy]apply dpl command.
When this option is used, the Linux kernel fsl-mc bus must wait for
the firmware to finish parsing the DPL before proceeding with probing
all the DPAA2 objects.

This provides GPIO support over SCMI. It is built on top of the
pinctrl-scmi driver. A typical device tree entry might look like
this:
gpio1 {
compatible = "scmi-pinctrl-gpio";
gpio-controller;
#gpio-cells = <2>;
ngpios = <10>;
gpio-ranges = <&scmi_pinctrl 0 8 4>,
<&scmi_pinctrl 4 12 1>,
<&scmi_pinctrl 5 15 1>,
<&scmi_pinctrl 6 17 4>;
pinctrl-names = "default";
pinctrl-0 = <&i2c2_pins>;
};
In this GPIO driver the one thing which is different is that in the
gpio-ranges the first numbers which represent how the pins are exposed
to the users have to start at zero and it can't have gaps.

The SCMI clock protocol version was only being fetched when CLK_CCF
was enabled. On non-CCF platforms, the probe function returned early
without fetching the version, leaving priv->version as 0.
This caused issues because code paths like scmi_clk_gate() and
scmi_clk_get_permissions() depend on priv->version to determine
which protocol message format to use, even in non-CCF mode.
Fix this by moving the scmi_generic_protocol_version() call before
the CLK_CCF check, ensuring the version is fetched for both CCF and
non-CCF platforms.
Tested on am62lx_evm.

David Lechner <dlechner@baylibre.com> says:
This is a series adding support for reading U-Boot env directly from
SCSI devices that do not have a partition table, similar to how we can
already do this for MMC devices.
The motivation behind this is that MediaTek's BSP is already using the
same disk images for both MMC and UFS devices, so we need to be able to
read the env from SCSI devices without requiring a partition UUID.
The series starts with cleaning up a few oddities we noticed in the
existing code. Then some refactoring so that the env code manages
calling scsi_scan() so that we don't have to duplicate that for the
new code path. Then finally, the last few patches add and document the
new functionality.

Change scsi_get_blk_by_uuid() to return -ENODEV instead of -1 on error.
Other scsi_* functions return an error code rather than -1.
1 is EPERM, which doesn't make sense here. So we use ENODEV instead. The
only caller only checks for !success, so changing the value has no
effect on the caller.
