Add the following functions to get a specific device's DMA ranges:
 - dev_get_dma_range()
 - ofnode_get_dma_range()
 - of_get_dma_range()
 - fdt_get_dma_range()
They are specially useful in oder to be able validate a physical address
space range into a bus's and to convert addresses from and to address

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

do not pass NULL pointer to libfdt

2021-01-30T21:25:42+00:00

Re-send because of line-wraps.

Without this patch, u-boot just hangs if the fdt pointer is
not initialized. The diagnostic subsystems are not yet initialized,
so all you get is a blind hang.

dm: core: Don't inline dev_read...() calls with of-platdata

2021-01-30T21:25:41+00:00

At present if these calls are used with of-platdata, a confusing error is
produced, referring to a function not actually called by the code causing
the problem.

Fix this by not inlining, so that the error mentions the dev_read_...()
function and it is more obvious what is going on.

dm: core: Access device ofnode through functions

2021-01-05T19:24:41+00:00

At present ofnode is present in the device even if it is never used. With
of-platdata this field is not used, so can be removed. In preparation for
this, change the access to go through inline functions.

dm: core: Use dev_has_ofnode() instead of dev_of_valid()

2021-01-05T19:24:41+00:00

We have two functions which do the same thing. Standardise on
dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in
normal operation: it is either null or missing.

Also move the functions into one place.

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);
