test/py: Update test_bind

2020-08-22T13:58:39+00:00

As bind-test is now binded at sandbox startup and no more by
test_bind.py, bind-test nodes are not located at the end of
"dm tree" output, but can be located everywhere in the tree, so
bind-test output could either be:

 simple_bus    0  [   ]   generic_simple_bus    |-- bind-test
 phy           0  [   ]   phy_sandbox           |   |-- bind-test-child1
 simple_bus    1  [   ]   generic_simple_bus    |   `-- bind-test-child2

or:

 simple_bus    5  [   ]   generic_simple_bus    `-- bind-test
 phy           2  [   ]   phy_sandbox               |-- bind-test-child1
 simple_bus    6  [   ]   generic_simple_bus        `-- bind-test-child2

in_tree() function need to be updated to take care of that change.

sandbox: dts: Add compatible string for bind-test node

2020-08-22T13:58:39+00:00

Usage of lists_bind_fdt() in bind command imposes to add
a compatible string for bind-test node.

Others impacts are:
  - bind-test node is binded at sandbox start, so no need to bind it
    in test_bind_unbind_with_node() test.
  - As explained just above, after sandbox start, now a phy exist.
    In test/dm/phy.c, it was verified that a third phy didn't exist,
    now we must verified that a fourth phy doesn't exist.

drivers: rename drivers to match compatible string

2020-07-10T00:57:22+00:00

When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

test/py: Use raw strings more to avoid deprecation warnings

2019-10-30T21:48:47+00:00

We have two further uses of raw string usage in the test/py codebase
that are used under CI.  The first of which is under the bind test and
is a direct update.  The second of which is to strip VT100 codes from
the match buffer.  While switching this to a raw string is also a direct
update, the comment it notes that problems were encountered on Ubuntu
14.04 (and whatever Python 2 version that was) that required slight
tweaks to the regex.  Replace that now that we're saying Python 3.5 is
the minimum.

dm: Tidy up dump output when there are many devices

2019-10-15T14:40:03+00:00

At present the 'Index' column of 'dm tree' assumes there is
two digits, this patch increase it to 3 digits.

It also aligns output of 'dm uclass', assuming the same 3 digits index.

The boards with CONFIG_PINCTRL_FULL activated have one pinconfig
by pin configuration, so they can have more than 100 devices
pinconfig (for example with stm32mp157c-ev1 board we have
106 pinconfig node).

test: Use single quote consistently

2019-01-15T20:28:41+00:00

Some tests have ended up using double quotes where single quotes could be
used. Adjust this for consistency with the rest of U-Boot's Python code.

dm: Tidy up 'dm tree' output when there are many devices

2019-01-15T00:47:13+00:00

At present the 'Index' column assumes there is only one digit. But on some
devices (e.g. snow) there are a lot of regulators and GPIO banks. Adjust
the output to allow for two digits without messing up the display.

Also capatalise the heading to match.

dm: core: Widen the dump tree to show more of the driver's name.

2018-11-21T02:14:22+00:00

With drivers that have prefix names that are quite long (like
'versatile_') it is useful to have a wider column for the driver's
name when dumping the device driver tree.

Also update the tests to take into account the wider output format.

cmd: Add bind/unbind commands to bind a device to a driver from the command line

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

In some cases it can be useful to be able to bind a device to a driver from
the command line.
The obvious example is for versatile devices such as USB gadget.
Another use case is when the devices are not yet ready at startup and
require some setup before the drivers are bound (ex: FPGA which bitsream is
fetched from a mass storage or ethernet)

usage example:

bind usb_dev_generic 0 usb_ether
unbind usb_dev_generic 0 usb_ether
or
unbind eth 1

bind /ocp/omap_dwc3@48380000/usb@48390000 usb_ether
unbind /ocp/omap_dwc3@48380000/usb@48390000
