dm: core: Fix devfdt_get_addr_ptr return value

2020-08-22T13:59:14+00:00

According to the description of devfdt_get_addr_ptr, this function should
return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE.

Fix this by making devfdt_get_addr_ptr return NULL on failure, as
described in the function comments. Also, update the drivers currently
checking (void *)FDT_ADDR_T_NONE to check for NULL.

dm: core: Use const device for the devfdt...() interface

2020-02-06T02:33:45+00:00

These functions do not modify the device so should use a const pointer to
it. Update the code accordingly.

dm: core: Drop fdtdec_get_pci_addr()

2019-10-08T05:57:47+00:00

This function ise effectively replaced by ofnode_read_pci_addr() which
works with flat tree. Delete it to avoid code duplication.

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.

dm: core: add support for getting register address and size

2019-08-12T17:33:39+00:00

Current dev_read_*() API lacks support to get address and size
of a "reg" property by name or index. Add support for the same.

Livetree support has been added but not tested on real hardware.

The existing unit tests testing reading address from device-tree
have been updated to test address as well as size.

dm: core: Change platform specific translation-offset handling

2019-04-24T02:26:43+00:00

Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.

This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

dm: core: add functions to get/remap I/O addresses by name

2018-12-05T13:06:44+00:00

This functions allow us to get and remap I/O addresses by name, which is useful when there are multiple reg addresses indexed by reg-names property.
This is needed in bmips dma/eth patch series, but can also be used on many
other drivers.
