dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()

2017-07-11T16:08:20+00:00

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.

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: Use dm.h header when driver mode is used

2017-06-01T12:57:52+00:00

This header includes things that are needed to make driver build. Adjust
existing users to include that always, even if other dm/ includes are
present

dm: allow limiting pre-reloc markings to spl or tpl

2017-03-16T22:03:44+00:00

Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.

So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.

The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

libfdt: Bring in upstream stringlist functions

2016-10-13T19:54:10+00:00

These have now landed upstream. The naming is different and in one case the
function signature has changed. Update the code to match.

This applies the following upstream commits by
Thierry Reding  :

   604e61e fdt: Add functions to retrieve strings
   8702bd1 fdt: Add a function to get the index of a string
   2218387 fdt: Add a function to count strings

pinctrl: add the DM_UC_FLAG_SEQ_ALIAS flag for numbering the devices

2016-05-25T01:00:18+00:00

It is possible to have multiple pin controllers in the system. Use the
DM_UC_FLAG_SEQ_ALIAS flag so that the pinctrl instances are assigned
a sequence number.

dm: pinctrl: Add a way for a GPIO driver to obtain a pin function

2016-01-22T03:42:35+00:00

GPIO drivers want to be able to show if a pin is enabled for input, output,
or is being used by another function. Some drivers can easily find this
and the code is included in the driver. For some SoCs this is more complex.
Conceptually this should be handled by pinctrl rather than GPIO. Most
pinctrl drivers will have this feature anyway.

Add a method by which a GPIO driver can obtain the pin mux value given a
GPIO reference. This avoids repeating the code in two places.

dm: pinctrl: Add a function to parse PIN_CONFIG flags

2016-01-22T03:42:34+00:00

Add a function which produces a flags word from a few common PIN_CONFIG
settings. This is useful for simple pinctrl drivers that don't need to worry
about drive strength, etc.
