dm: core: Decouple DM from DT

2019-09-02T15:38:42+00:00

Some of the DM functions depend on OF_CONTROL, which is incorrect.
DM and DT are orthogonal. Add macro guards around such functions to
avoid compiling them in when DM is enabled, while OF_CONTROL is not.

dm: device: make power domain calls optional

2019-07-24T19:54:08+00:00

Reduce power domain calls when CONFIG_POWER_DOMAIN is disabled.
With gcc v8.2, this change saves 104 bytes.

dm: core: Call clk_set_defaults() during probe() only for a valid ofnode

2019-07-24T19:54:08+00:00

Without a valid ofnode, it's meaningless to call clk_set_defaults()
to process various properties.

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: Add a few more specific child-finding functions

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

Add two functions which can find a child device by uclass or by name.
The first is useful with Multi-Function-Devices (MFDs) to find one of a
particular type. The second is useful when only the name is known.

dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()

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

Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.

dm: core: Add a function to find the first inactive child

2018-10-09T10:40:27+00:00

Some devices have children and want to press an existing inactive child
into service when needed. Add a function to help with this.

dm: core: Update some functions to use const

2018-10-09T10:40:27+00:00

Quite a few functions do not actually modify the device that is passed in.
Update the function signatures to reflect that.

dm: core: Alloc uclass-private data to be cache-aligned

There is no reason why this feature should not be supported for uclass-
private data. Update the code accordingly.

core: Add dev_{disable,enable}_by_path

2018-09-29T17:49:35+00:00

We cannot use device structures to disable devices, since getting
them with the API functions would bind and activate the device, which
would fail if the underlying device does not exist.
