dm: Introduce xxx_get_dma_range()

2021-02-18T10:56:25+00:00

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
spaces.

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.

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.
