core: read: fix dev_read_addr_size()

The behaviour of dev_read_addr_size() is surprising as it does not
handle #address-cells and #size-cells but instead hardcodes the values
based on sizeof(fdt_addr_t).

This is different from dev_read_addr_size_index() and
dev_read_addr_size_name() both of which do read the cell sizes from the
device tree.

Since dev_read_addr_size() is only used by a single driver and this
driver is broken when CONFIG_FDT_64BIT does not match the address size
in the device tree, fix the function to behave like all of the other
similarly named functions.  Drop the property name argument as the only

Eugen Hristev [Thu, 4 May 2023 12:22:21 +0000 (15:22 +0300)]
dm: core: of_access: fix return value in of_property_match_string

of_property_match_string calls of_find_property to search for the
string property.
If the device node does not exist, of_find_property returns NULL, and
of_property_match_string returns -EINVAL, which is correct.
However, if the device node exists, but the property is not found,
of_find_property still returns NULL, but it will place -FDT_ERR_NOTFOUND
in the *lenp variable.
of_property_match_string does not use the lenp parameter, thus this error
case is being lost, and treated as if the node is NULL, and returns
-EINVAL, which is incorrect.

The callers of of_property_match_string treat the error differently if
the return value is -EINVAL or -ENOENT, e.g. in dwc3 driver:

ret = generic_phy_get_by_name(dev, "usb3-phy", &phy);
if (!ret) {
ret = generic_phy_init(&phy);
if (ret)
return ret;
} else if (ret != -ENOENT && ret != -ENODATA) {
debug("could not get phy (err %d)\n", ret);
return ret;
} else {
phy.dev = NULL;
}

So the caller drivers will just consider the property missing if -ENOENT
is returned, versus the case of -EINVAL, which means something else.

To fix this situation, changed the code to call the of_find_property
with the right third argument to catch this error code and treat it
accordingly.
