dm: add cells_count parameter in *_count_phandle_with_args

2020-10-06T15:07:54+00:00

The cell_count argument is required when cells_name is NULL.

This patch adds this parameter in live tree API
- of_count_phandle_with_args
- ofnode_count_phandle_with_args
- dev_count_phandle_with_args

This parameter solves issue when these API is used to count
the number of element of a cell without cell name. This parameter
allow to force the size cell.

For example:
  count = dev_count_phandle_with_args(dev, "array", NULL, 3);

dm: Fix error handling for dev_read_addr_ptr

2020-07-01T07:01:21+00:00

dev_read_addr_ptr had different semantics depending on whether OF_LIVE was
enabled. This patch converts both implementations to return NULL on error,
and converts all call sites which check for FDT_ADDR_T_NONE to check for
NULL instead. This patch also removes the call to map_physmem, since we
have dev_remap_addr* for those semantics.

dm: core: Reorder include files in read.c

2020-05-30T02:55:45+00:00

Including the assembler headers before including common.h etc leads to
compilation errors upon MIPS64 based platforms using OF_LIVE. This
patch reorders the include files to the "correct" oder.

dm: core: add ofnode and dev function to iterate on node property

2020-04-17T03:06:54+00:00

Add functions to iterate on all property with livetree
- dev_read_first_prop
- dev_read_next_prop
- dev_read_prop_by_prop
and
- ofnode_get_first_property
- ofnode_get_next_property
- ofnode_get_property_by_prop

And helper: dev_for_each_property

For example:
struct ofprop property;

dev_for_each_property(property, config) {
	value = dev_read_prop_by_prop(&property, &propname, &len);

or:

for (res = ofnode_get_first_property(node, &property);
     !res;
     res = ofnode_get_next_property(&property))
{
     value = ofnode_get_property_by_prop(&property, &propname, &len);

dm: pci: Add a function to read a PCI BAR

2019-10-08T05:57:43+00:00

At present PCI address transaction is not supported so drivers must
manually read the correct BAR after reading the device tree info. The
ns16550 has a suitable implementation, so move this code into the core
DM support.

Note that there is no live-tree equivalent at present.
