dm: core: add ofnode_count_phandle_with_args()

2017-07-28T21:34:08+00:00

This function is usefull to get phandle number contained
in a property list.
For example,  this allows to allocate the right amount
of memory to keep clock's reference contained into the
"clocks" property.

To implement it, either of_count_phandle_with_args() or
fdtdec_parse_phandle_with_args() are used respectively
for live tree and flat tree.
By passing index = -1, these 2 functions returns the
number of phandle contained into the property list.

Add also the dev_count_phandle_with_args() based on
ofnode_count_phandle_with_args()

dm: core: Add ofnode_read_resource()

2017-07-28T18:02:47+00:00

We sometimes need to read a resource from an arbitrary node. In any case
for consistency we should not put the live-tree switching code in
a dev_read_...() function. Update this to suit.

dm: ofnode: change return type of dev_read_prop() to opaque pointer

2017-07-28T18:02:47+00:00

DT property values can be strings as well as integers.  This is why
of_get_property/fdt_getprop returns an opaque pointer.

serial: stm32x7: migrate serial struct to driver

2017-07-26T15:26:54+00:00

This allow to remove include/dm/platform_data/serial_stm32x7.h
which was included in the past by stm32x7 driver and by
stm32f746-disco.c board file.
Since patch 42bf5e7c27 "serial: stm32f7: add device tree support"
this file is no more needed in board file.

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: Add functions to obtain node's address/size cells

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

The of_n_addr_cells() and of_n_size_cells() functions are useful for
getting the size of addresses in a node, but in a few places U-Boot needs
to obtain the actual property value for a node without walking up the
stack. Add functions for this and just the existing code to use it.

Add a comment to the existing ofnode functions which do not do the right
thing with a flat tree.

This fixes a problem reading PCI addresses.

dm: core: Add dev_read_enabled() to check if a device is enabled

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

This function allows a device's status to be read. This indicates whether
the device should be enabled or disabled.

Note: In normal operation disabled devices will not be present in the
driver-model tree.

dm: core: Add dev_read_resource() to read device resources

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

Add a function which reads resources from a device, such as the device
hardware address. This uses the "reg" property in the device.

Unlike other functions there is little sense in inlining this when
livetree is not being used because it has some logic in it and this would
just bloat the code size.
