dm: fix logic of lists_bind_fdt()

2022-07-26T08:30:56+00:00

If parameter drv of lists_bind_fdt() is specified, we shall bind only to
this very driver and to no other.

If the driver drv has an of_match property, we shall only bind to the
driver if it matches the compatible string of the device.

dm: avoid NULL dereference in lists_bind_fdt()

2022-07-26T08:30:56+00:00

If parameter drv of lists_bind_fdt() is specified, we want to bind to this
specific driver even if its field of_match is NULL.

If entry->of_match is NULL, we should not dereference it in a debug
statement.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

drivers: core: lists: fix for loop index type

2021-12-02T16:15:43+00:00

* fixes the bug in function bind_drivers_pass that for
CONFIG_CC_OPTIMIZE_FOR_SIZE=n and no entries in the driver_info list,
i.e. n_ents == 0, the processor steps into the first loop iteration
despite the loop condition being false.
* the Xilinx Zynq-7000 device would eventually hang due to an attempted
access to an invalid memory address
* the bug is fixed by changing the type of idx from uint to int

cmd: bind: Fix driver binding on a device

2021-10-12T12:19:52+00:00

Fix a regression brings by commit 84f8e36f03fa ("cmd: bind: allow to
bind driver with driver data")

As example, the following bind command doesn't work:

   bind /soc/usb-otg@49000000 usb_ether

As usb_ether driver has no compatible string, it can't be find by
lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(),
the driver entry is known, pass it to lists_bind_fdt() to force the driver
entry selection.

For this, add a new parameter struct *driver to lists_bind_fdt().
Fix also all lists_bind_fdt() callers.

At present the name 'uclass_driver' is used for the uclass linker list.

dm: Support parent devices with of-platdata

2020-10-29T20:42:18+00:00

At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine
which bus they are on.

Add support for setting the parent correctly, by storing the parent
driver_info index in dtoc and reading this in lists_bind_drivers(). This
needs multiple passes since we must process children after their parents
already have been bound.
