These should finish with a newline like the others.

dm: usb: Document that mixing DM_DEVICE_REMOVE and DM_USB is a bad idea

2015-07-21T23:39:36+00:00

Document that mixing DM_DEVICE_REMOVE and DM_USB is a bad idea, and also why
this is a bad idea.

dm: Export device_remove_children / device_unbind_children

2015-07-21T23:39:35+00:00

These functions are useful to remove all children from an usb bus before
rescanning the bus. Give them a better name and export them.

dm: remove redundant CONFIG_DM from driver/core/Makefile

2015-07-21T23:39:34+00:00

As you see in driver/Makefile, Kbuild descends into the driver/core/
directory only when CONFIG_DM is enabled.

dm: do not set DM_FLAG_ACTIVATED twice

2015-07-21T23:39:34+00:00

Currently, DM_FLAG_ACTIVATED is set twice; before calling
uclass_pre_probe_device() and again before calling drv->probe().

It looks like Simon's intention is the first one.
The DM_FLAG_ACTIVATED was moved twice, by commit 02eeb1bbb174
(dm: core: Mark device as active before calling its probe()
method), and then by commit 206d4d2b4b30 (dm: core: Mark device
as active before calling uclass probe() methods).
The first marking was added by the last move.

dm: change dm_warn() message into debug() in uclass_add()

2015-07-21T23:39:34+00:00

The command "dm uclass" tries to display all the UClasses, but
some of them might be disabled by Kconfig.

The function do_dm_dump_uclass() iterates over all the UClass IDs
and calls uclass_get() for each of them.  Then, it displays annoying
message "Cannot find uclass for id ..." every time it fails to get
the UClass.

As a result, we get much noisier log for the "dm uclass" command.

  => dm uclass
  uclass 0: root
  - * root_driver @ bfb54028, seq 0, (req -1)

  Cannot find uclass for id 1: please add the UCLASS_DRIVER() ...
  Cannot find uclass for id 2: please add the UCLASS_DRIVER() ...
  Cannot find uclass for id 3: please add the UCLASS_DRIVER() ...
  Cannot find uclass for id 4: please add the UCLASS_DRIVER() ...
  Cannot find uclass for id 5: please add the UCLASS_DRIVER() ...
  Cannot find uclass for id 6: please add the UCLASS_DRIVER() ...

This commit suppresses these warnings.

dm: core: Add device checking to syscon_get_regmap()

2015-07-21T23:39:33+00:00

This function can only handle a syscon device. It is possible that someone
will make a mistake, so add a check for this.

Also we should return -ENODEV when a device cannot be found, so update the
syscon_get_regmap_by_driver_data() to follow this convention.

dm: Add support for generic system controllers (syscon)

2015-07-21T23:39:24+00:00

Many SoCs have a number of system controllers which are dealt with as a
group by a single driver. It is a pain to have to add lots of compatible
strings and/or separate drivers for each. Instead we can identify the
controllers by a number and request the address of the one we want.

Add a simple implementation of this which can be used by SoC driver code.

dm: Add support for register maps (regmap)

2015-07-21T23:39:23+00:00

Add a simple implementaton of register maps, supporting only direct I/O
for now. This can be enhanced later to support buses which have registers,
such as I2C, SPI and PCI.

It allows drivers which can operate with multiple buses to avoid dealing
with the particulars of register access on that bus.

dm: core: Correct device_get_child_by_of_offset() parameter

2015-07-21T23:39:23+00:00

This parameter is named 'seq' but should be named 'of_offset'.
