timer: Tidy up use of notrace

2023-02-11T17:22:34+00:00

Tracing is typically enabled by the time driver model starts up, so there
is no point in adding a 'notrace' to the timer-init function. However,
once the driver model timer is enabled, we do need to be able to access
the timer's private data when reading the timer, so add it to the core
function needed for that.

Update the function's documentation while we are here.

drivers: core: ofnode: Add panel timing decode.

2023-02-04T17:13:21+00:00

ofnode_decode_display_timing supports reading timing parameters from
subnode of display-timings node, for displays supporting multiple
resolution, in case if a display supports single resolution, it fails
reading directly from display-timings node, to support it
ofnode_decode_panel_timing is added.

dm: core: Use full printf() format when possible

2023-01-26T17:47:45+00:00

Use a more accurate check for determining if the full format string will
be handled correctly, since SPL_USE_TINY_PRINTF can be disabled.

event: Correct dependencies on the EVENT framework

2023-01-18T17:46:13+00:00

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

dm: fix probing of all devices that have u-boot, dm-pre-reloc in SPL/TPL

2023-01-12T19:06:16+00:00

Currently, dm_probe_devices checks that the flags of the device contains
DM_FLAG_PRE_RELOC. However DM_FLAG_PRE_RELOC is a driver - and not a
device - flag. This means that the check in pre_reloc_only mode would
always fail.

Instead, what was aimed to be checked is that either the driver of the
device has the flag set, or that the device has the u-boot,dm-pre-reloc
Device Tree property set.

So let's fix the check to allow u-boot,dm-pre-reloc devices to be
probed.

global: Move remaining CONFIG_SYS_* to CFG_SYS_*

2022-12-05T21:06:08+00:00

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

dm: core: Fix iteration over driver_info records

2022-12-02T13:39:00+00:00

We should only perform additional iteration steps when needed to
initialize the parent of a device. Other binding errors (such as a
missing driver) should not lead to additional iteration steps.

Unnecessary iteration steps can cause issues when memory is tightly
constrained (such as in the TPL/SPL) since device_bind_by_name()
unconditionally allocates memory for a struct udevice. On the SanCloud
BBE this led to boot failure caused by memory exhaustion in the SPL
when booting from SPI flash.

net: phy: Fix ethernet-phy-id in the code

Use dot instead of comma. The fix doesn't affect anything but it is good to
be aligned with used pattern. The first is used only for string size
calculation and the second change is in the comment.

dm: core: Do not stop uclass iteration on error

2022-10-29T13:36:33+00:00

When probing a device fails NULL pointer is returned, and following
devices in uclass list cannot be iterated. Skip to next device on error
instead.

With that the only condition under which these simple iteration
functions return error is when the dm is not initialized at uclass_get
time. This is not all that interesting, change return type to void.
