dm: core: Update device_bind_driver_to_node() to use ofnode

2017-06-01T13:03:08+00:00

Adjust this function to us an ofnode instead of an offset, so it can be
used with livetree. This involves updating all callers.

dm: core: Allow binding a device from a live tree

2017-06-01T13:03:08+00:00

When a live tree is being used we need to record the node that was used to
create the device. Update device_bind_with_driver_data() to support this.

dm: core: Set return value first in lists_bind_fdt()

2017-06-01T13:03:05+00:00

Adjust the order to make it clear that *devp is set to NULL by default.

dm: core: Match compatible strings in order of priority

2016-09-21T13:04:32+00:00

Device model drivers have previously been matched to FDT nodes by virtue
of being the first driver in the driver list to be compatible with the
node. This ignores the fact that compatible strings in the device tree
are listed in order of priority - that is, if we have a node with 2
compatible strings & a driver that matches each then we should always
probe the driver that matches the first compatible string.

Fix this by looping through the compatible strings for a node when
attempting to bind it in lists_bind_fdt and checking each driver for
a match of the first string, then each driver for a match of the second
string etc. Effectively this inverts the loops over compatible strings &
drivers.

dm: core: Don't use device tree with of-platdata

2016-07-15T02:40:24+00:00

When CONFIG_SPL_OF_PLATDATA is enabled we should not access the device
tree. Remove all references to this in the core driver-model code.

dm: allow setting driver_data before/during bind

2016-05-27T02:48:31+00:00

This will allow a driver's bind function to use the driver data. One
example is the Tegra186 GPIO driver, which instantiates child devices
for each of its GPIO ports, yet supports two different HW instances each
with a different set of ports, and identified by the udevice_id .data
field.

dm: core: allow drivers to refuse to bind

2016-05-17T15:54:43+00:00

In some cases, drivers may not want to bind to a device. Allow bind() to
return -ENODEV in this case, and don't treat this as an error. This can
be useful in situations where some information source other than the DT
node's main status property indicates whether the device should be
enabled, for example other DT properties might indicate this, or the
driver might query non-DT sources such as system fuses or a version number
register.

dm: core: Display the error number when driver binding fails

2016-01-24T04:07:18+00:00

This is often -96 (-EPFNOSUPPORT) which indicates that the uclass is not
compiled in. Display the error number to make this easier to spot.

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.
