8334431651 test: call hexdump tests via ut lib
The unit tests in test/lib/hexdump.c are not related to the device tree.
So they should be executed via `ut lib` and not via `ut dm`.

cc4a224af2 power: regulator: Introduce regulator_set_enable_if_allowed api
regulator_set_enable() api throws an error in the following three cases:
- when requested to disable an always-on regulator
- when set_enable() ops not provided by regulator driver
- when enabling is actually failed.(Error returned by the regulator driver)

Sometimes consumer drivers doesn't want to track the first two scenarios
and just need to worry about the case where enabling is actually failed.
But it is also a good practice to have an error value returned in the
first two cases.

So introduce an api regulator_set_enable_if_allowed() which ignores the
first two error cases and returns an error as given by regulator driver.
Consumer drivers can use this api need not worry about the first two
error conditions.

This patch makes sure all deleted or free entries are always found and

To trash your environment, simply run this loop:

a735e6e9d6 net: explicitly assign errno to return code in case of network failure
When dealing with two ethernet ports and having "netretry" set
to "once", it could occur that the connection (e.g. an ARP
request) failed, hence the status of the netloop was
"NETLOOP_FAIL". Due to the setting of "netretry", the network
logic would then switch to the other network interface,
assigning "ret" with the return value of "net_start_again()".
If this call succeeded we would return 0 (i.e. success) to
the caller when in reality the network action failed.

4cc8af8037 lib: lmb: extend lmb for checks at load time
This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.

lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.

lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.

0f7c51a676 lib: lmb: reserving overlapping regions should fail
lmb_add_region handles overlapping regions wrong: instead of merging
or rejecting to add a new reserved region that overlaps an existing
one, it just adds the new region.

Since internally the same function is used for lmb_alloc, change
lmb_add_region to reject overlapping regions.

Also, to keep reserved memory correct after 'free', reserved entries
created by allocating memory must not set their size to a multiple
of alignment but to the original size. This ensures the reserved
region is completely removed when the caller calls 'lmb_free', as
this one takes the same size as passed to 'lmb_alloc' etc.

Add test to assert this.

At present the 'Index' column assumes there is only one digit. But on some
devices (e.g. snow) there are a lot of regulators and GPIO banks. Adjust
the output to allow for two digits without messing up the display.

Also capatalise the heading to match.

Fixes: 5197dafc42 (dm: core: Widen the dump tree to show more of the
driver's name.)

5766a27176 tests: enable DT overlay tests by default
Enable device tree overlay tests by default if unit tests are selected
and the runtime is configured via device tree.

Overlays have been mainlined in the device tree compiler so there is no
reason anymore to disable the tests by default.

The "dm" command under CONFIG_CMD_DM should live under cmd/ rather than
test/dm/ so move it.

a1b17e4f4c dm: core: Add a function to read into a unsigned int
The current dev_read...() functions use s32 and u32 which are convenient
for device tree but not so useful for normal code, which often wants to
use normal integers for values.

Add a helper which supports returning an unsigned int. Also add signed
versions of the unsigned readers.

d490189865 dm: sound: Create a uclass for sound
The sound driver pulls together the audio codec and i2s drivers in order
to actually make sounds. It supports setup() and play() methods. The
sound_find_codec_i2s() function allows locating the linked codec and i2s
devices. They can be referred to from uclass-private data.

Add a uclass and a test for sound.
