dm: core: Add support for simple-bus

2014-10-22T16:36:56+00:00

Add a driver for the simple-bus nodes, which allows devices within these
nodes to be bound.

dm: core: Allow parents to pass data to children during probe

2014-10-22T16:36:46+00:00

Buses sometimes want to pass data to their children when they are probed.
For example, a SPI bus may want to tell the slave device about the chip
select it is connected to.

Add a new function to permit the parent data to be supplied to the child.

dm: core: Add functions for iterating through device children

2014-10-22T16:36:45+00:00

Buses need to iterate through their children in some situations. Add a few
functions to make this easy.

dm: simplify the loop in lists_driver_lookup_name()

2014-10-22T16:32:16+00:00

if (strncmp(name, entry->name, len))
                continue;

        /* Full match */
        if (len == strlen(entry->name))
                return entry;

is equivalent to:

        if (!strcmp(name, entry->name))
                return entry;

The latter is simpler.

dm: do not check the existence of uclass operation

2014-10-22T16:32:16+00:00

The function uclass_add() checks uc_drv->ops as follows:

        if (uc_drv->ops) {
                dm_warn("No ops for uclass id %d\n", id);
                return -EINVAL;
        }

It seems odd because it warns "No ops" when uc_drv->ops has
non-NULL pointer.  (Looks opposite.)

Anyway, most of UCLASS_DRIVER entries have no .ops member.
This check makes no sense.

kbuild: refactor some makefiles

2014-09-24T22:30:29+00:00

[1] Move driver/core/, driver/input/ and drivers/input/ entries
    from the top Makefile to drivers/Makefile

[2] Remove the conditional by CONFIG_DM in drivers/core/Makefile
    because the whole drivers/core directory is already selected
    by CONFIG_DM in the upper level

[3] Likewise for CONFIG_DM_DEMO in drivers/demo/Makefile

[4] Simplify common/Makefile - both CONFIG_DDR_SPD and
    CONFIG_SPD_EEPROM are boolean macros so they can directly
    select objects

kconfig: add blank Kconfig files

2014-09-24T22:30:28+00:00

This would be useful to start moving various config options.

dm: avoid dev->req_seq overflow

2014-09-23T18:44:31+00:00

Since dev->req_seq value is initialized from "reg" property of fdt node,
there is posibility, that address value contained in fdt is greater than
INT_MAX, and then value in dev->req_seq is negative which led to probe()
fail.

This patch fix this problem by ensuring that req_seq is positive, unless
it's one of errno codes.

dm: core: Allow device_bind() to used without CONFIG_OF_CONTROL

2014-09-23T18:44:30+00:00

The sequence number support in driver model requires device tree control.
It should be skipped if CONFIG_OF_CONTROL is not defined, and should not
require functions from fdtdec.
