libfdt: move headers to and

2018-03-05T15:16:28+00:00

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include       -> #include 
  #include   -> #include

dm: core: parse chosen node

2018-01-15T16:35:38+00:00

This is the node that would contain, for example, the framebuffer setup
by an earlier stage.

dm: replace dm_dbg() with pr_debug()

2017-10-04T16:00:21+00:00

As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

dm: core: add clocks node scan

2017-09-12T03:43:58+00:00

Currently, all fixed-clock declared in "clocks" node in device tree
can be binded by clk_fixed_rate.c driver only if each of them have
the "simple-bus" compatible string.
This constraint has been invoked here [1].

This patch offers a solution to avoid adding "simple-bus" compatible
string to nodes that are not busses.

dm: core: Scan the live tree when setting up driver model

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

When starting up driver model with a live tree we need to scan the tree
for devices. Add code to handle this.

dm: core: Update lists_bind_fdt() to use ofnode

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

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

dm: core: Add ofnode to represent device tree nodes

2017-06-01T13:03:04+00:00

With live tree we need a struct device_node * to reference a node. With
the existing flat tree, we need an int offset. We need to unify these into
a single value which can represent both.

Add an ofnode union for this and adjust existing code to move to this.

dm: core: Dont export dm_scan_fdt_node()

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

This function is only used in one place. It is better to just declare it
internally since there is a simpler replacement for use outside the
driver-model core code.

dm: core: Add dm_remove_devices_flags() and hook it into device_remove()

2017-04-05T02:15:10+00:00

The new function dm_remove_devices_flags() is intented for driver specific
last-stage cleanup operations before the OS is started. This patch adds
this functionality and hooks it into the common device_remove()
function.

Drivers wanting to use this feature for some last-stage removal calls,
need to add one of the DM_REMOVE_xx flags to their driver .flags.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.
