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.

iommu: Add DMA mapping operations

2023-01-27T19:47:57+00:00

In order to support IOMMUs in non-bypass mode we need device ops
to map and unmap DMA memory.  The map operation enters a mapping
for a region specified by CPU address and size into the translation
table of the IOMMU and returns a DMA address suitable for
programming the device to do DMA.  The unmap operation removes
this mapping from the translation table of the IOMMU.

net: ethoc: Remove non-DM_ETH code

2022-12-07T21:04:17+00:00

As DM_ETH is required for all network drivers, it's now safe to
remove the non-DM_ETH support code.

dm: sandbox: Create a new HOST uclass

2022-11-07T23:24:30+00:00

Sandbox supports block devices which can access files on the host machine.
At present there is no uclass for this. The devices are attached to the
root devic. The block-device type is therefore set to UCLASS_ROOT which
is confusing.

Block devices should be attached to a 'media' device instead, something
which handles access to the actual media and provides the block driver
for the block device.

Create a new uclass to handle this. It supports two operations, to attach
and detach a file on the host machine.

For now this is not fully plumbed in.

FWU: Add FWU metadata structure and driver for accessing metadata

2022-10-31T18:47:32+00:00

In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, which is stored on
a dedicated partition. Add the metadata structure, and a driver model
uclass which provides functions to access the metadata. These are
generic API's, and implementations can be added based on parameters
like how the metadata partition is accessed and what type of storage
device houses the metadata.

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.

dm: core: Add note about device_probe idempotence

device_probe returns early when the device is already activated.
Add a note to the documentation that it can be used on already activated
devices.
