Functions for reading indexed values from device tree
Enhancements to 'dm' command
Log test enhancements and syslog driver
DM change to read parent ofdata before children
Minor fixes
|
|
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.

Use the new function dm_scan_fdt_ofnode_path() to scan all the nodes
which aren't devices themselves but may contain some:
- "/chosen"
- "/clocks"
- "/firmware"
The patch removes the strcmp call in recursive function dm_scan_fdt_live()
and also corrects a conflict with the 2 applied patches in
the commit 1712ca21924b ("dm: core: Scan /firmware node by default")
and in the commit 747558d01457 ("dm: fdt: scan for devices under
/firmware too"): the subnodes of "/firmware" (optee for example)
are bound 2 times.
For example the dm tree command result on STM32MP1 is:
STM32MP> dm tree

sandbox conversion to SDL2
TPM TEE driver
Various minor sandbox video enhancements
New driver model core utility functions
|
|
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.

There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.
Add support for this in sandbox along with a test.

At present we have uclass_foreach_dev() which requires that uclass_get()
be called beforehand to find the uclass. This is good if we suspect that
that function might fail, but often we know that the uclass is available.
Add a new helper which does this uclass_get() automatically, so that only
the uclass ID is needed.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few

This function is actually intended to read a string rather than a
property. All of its current callers use it that way. Also there is no way
to return the length of the property from this function.
Rename it to better indicate its purpose, using ofnode_read as the prefix
since this matches most other functions.
Also add some tests which are missing for these functions.
