pinctrl: Add third argument label for pinctrl_gpio_request() function

2022-07-28T13:17:45+00:00

This change allows to use pinctrl_gpio_request() function as a direct
pointer for dm_gpio_ops's .request callback.

pinctrl: Add new function pinctrl_generic_set_state_prefix()

2022-07-28T06:41:44+00:00

This new function pinctrl_generic_set_state_prefix() behaves like
pinctrl_generic_set_state() but it takes third string argument which is
used as the prefix for each device tree string property.

This is needed for Marvell pinctrl drivers, becase Linux device tree files
have pinmux properties prefixed by "marvell," string.

This change allows to use generic U-Boot pinctrl functions for Armada 38x
pinctrl driver without need to copy+paste of the majority U-Boot pinctrl
code.

dm: core: Add a command to show driver model statistics

2022-06-28T02:09:52+00:00

This command shows the memory used by driver model along with various
hints as to what it might be if some 'core' tags were moved to use the
tag list instead of a core (i.e. always-there) pointer.

This may help with future work to reduce memory usage.

dm: core: Add a way to collect memory usage

2022-06-28T02:09:52+00:00

Add a function for collecting the amount of memory used by driver model,
including devices, uclasses and attached data and tags.

This information can provide insights into how to reduce the memory
required by driver model. Future work may look at execution speed also.

dm: core: Support accessing core tags

2022-06-28T02:09:52+00:00

At present tag numbers are only allocated for non-core data, meaning that
the 'core' data, like priv and plat, are accessed through dedicated
functions.

For debugging and consistency it is convenient to use tags for this 'core'
data too. Add support for this, with new tag numbers and functions to
access the pointer and size for each.

Update one of the test drivers so that the uclass-private data can be
tested here.

There is some code duplication with functions like device_alloc_priv() but
this is not addressed for now. At some point, some rationalisation may
help to reduce code size, but more thought it needed on that.

dm: core: Switch the testbus driver to use a new struct

2022-06-28T02:09:52+00:00

At present this driver uses 'priv' struct to hold 'plat' data, which is
confusing. The contents of the strct don't matter, since only dtoc is
using it. Create a new struct with the correct name.

dm: core: Rename dm_dump_all()

2022-06-28T02:09:52+00:00

This is not a good name anymore as it does not dump everything. Rename it
to dm_dump_tree() to avoid confusion.

dm: core: Provide fallbacks for ofnode_conf_read_...

2022-06-28T02:09:51+00:00

Because fdt_get_config_str et al. were moved/renamed to
ofnode_conf_read_str, they now depend on CONFIG_DM as well as
CONFIG_OF_CONTROL. Add some fallback implementations, preventing a
linker error when CONFIG_SPL_OF_CONTROL and CONFIG_SPL_ENV_IS_IN_MMC are
enabled and CONFIG_SPL_DM is disabled.
