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.

dm: core: Use debug() instead of printf() for failures

2015-07-21T23:39:22+00:00

To avoid bloating SPL code, use debug() where possible in the driver model
core code. The error code is already returned, and can be investigated as
needed.

dm: core: Add a function to bind a driver for a device tree node

2015-04-30T03:02:32+00:00

Some device tree nodes do not have compatible strings but do require
drivers. This is pretty rare, and somewhat unfortunate. Add a function
to permit creation of a driver for any device tree node.

dm: core: Rename driver data function to dev_get_driver_data()

2015-04-18T17:11:19+00:00

The existing get_get_of_data() function provides access to both the driver's
compatible string and its driver data. However only the latter is actually
useful. Update the interface to reflect this and fix up existing users.

dm: core: remove unnecessary return condition in uclass lookup

2014-11-22T09:16:49+00:00

These conditions never happen.
 - There is no real uclass with UCLASS_INVALID id.
 - uclass never becomes NULL because ll_entry_start() always returns
   a valid pointer.

dm: core: remove unnecessary return condition in driver lookup

2014-11-22T09:16:49+00:00

The variable "drv" never becomes NULL because ll_entry_start()
always returns a valid pointer even if there are no entries.

The case "n_ents == 0" is covered by the following "for" loop.
