drivers: core: use strcmp when find device by name

2019-07-13T01:07:59+00:00

`if (!strncmp(dev->name, name, strlen(name)))` might find out
the wrong device, it might find out `dram_pll_ref_sel`, when name is
`dram_pll`. So use strcmp to avoid such issue.

dm: Add a No-op uclass

2019-07-05T12:19:41+00:00

This uclass is intended for devices that do not need any features from the
uclass, including binding children.
This will typically be used by devices that are used to bind child devices
but do not use dm_scan_fdt_dev() to do it. That is for example the case of
several USB wrappers that have 2 child devices (1 for device and 1 for
host) but bind only one at a any given time.

dm: device: fail uclass_find_first_device() if list_empty

2019-02-09T12:51:00+00:00

While uclass_find_device() fails with -ENODEV in case of list_empty
strangely uclass_find_first_device() returns 0.

Fix uclass_find_first_device() to also fail with -ENODEV instead.

dm: device: Allow using uclass_find_device_by_seq() without OF_CONTROL

2018-12-10T05:05:32+00:00

If OF_CONTROL is not enabled and DM_SEQ_ALIAS is enabled, we must
assign an alias (requested sequence number) to devices that belongs to a
class with the DM_UC_FLAG_SEQ_ALIAS flag. Otherwise
uclass_find_device_by_seq() cannot be used to get/probe a device. In
particular i2c_get_chip_for_busnum() cannot be used.

dm: core: Export uclass_find_device_by_phandle()

2018-11-29T16:30:05+00:00

This function may be useful to code outside of the code driver-model
implementation. Export it and add a test.

dm: uclass: Add uclass_next_device_err() to return a valid device

2018-11-16T21:51:55+00:00

Similarly to uclass_first_device_err(), add uclass_next_device_err()
which returns an error if there are no next devices in that uclass.

uclass: Use uclass_foreach_dev() macro instead of open coding

dm: core: Allow uclass to set up a device's child after it is probed

2018-11-14T17:16:27+00:00

Some buses need to set up their child devices after they are probed.
Support a common child_post_probe() method for the uclass.

With this change, the two APIs uclass_pre_probe_device() and
uclass_post_probe_device() become symmetric.

uclass: Add dev_get_uclass_index() to get the uclass/index of a device

2018-08-21T14:21:37+00:00

This function is the reciprocal of uclass_find_device().
It will be used to print the index information in dm tree dump.
