syscon: update syscon_node_to_regmap to use the DM functions

2018-12-15T16:49:56+00:00

+ Update the function syscon_node_to_regmap() to force bound on
  syscon uclass and directly use the list of device from DM.
+ Remove the static list syscon_list.

This patch avoid issue (crash) when syscon_node_to_regmap() is called
before and after reallocation (list content is invalid).

dm: core: Add a function to read into a unsigned int

2018-12-13T23:32:49+00:00

The current dev_read...() functions use s32 and u32 which are convenient
for device tree but not so useful for normal code, which often wants to
use normal integers for values.

Add a helper which supports returning an unsigned int. Also add signed
versions of the unsigned readers.

drivers: core: nullify gd->dm_root after dm_uninit()

2018-12-10T06:23:45+00:00

To reset the DM after a new dtb is loaded, we need to call dm_uninit()
and then dm_init(). This fails however because gd->dm_root is not nullified
by dm_uninit().
Fixing it by setting gd->dm_root in dm_uninit().

drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the Kconfig

2018-12-10T06:22:30+00:00

It is currently not possible to include the support to remove devices in
the SPL. This is however needed by platforms that re-select their dtb after
DM is initialized; they need to remove all the previously bound devices
before triggering a scan of the new DT.

Add a Kconfig option to be able to include the support for device removal
in the SPL.

dm: device: Allow using uclass_find_device_by_seq() without OF_CONTROL

2018-12-10T05:05:32+00:00

If OF_CONTROL is not enabled and DM_SEQ_ALIAS is enabled, we must
assign an alias (requested sequence number) to devices that belongs to a
class with the DM_UC_FLAG_SEQ_ALIAS flag. Otherwise
uclass_find_device_by_seq() cannot be used to get/probe a device. In
particular i2c_get_chip_for_busnum() cannot be used.

syscon: dm: Add a new method to get a regmap from DTS

2018-12-07T15:31:45+00:00

syscon_regmap_lookup_by_phandle() can be used to get the regmap of a syscon
device from a reference in the DTS. It operates similarly to the linux
version of the namesake function.

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.

2018-11-29T16:30:06+00:00

Currently the else part of ofnode_get_addr_index function
does not fetch addresses based on the index but rather just
returns the base address. Fix that.

dm: core: Add a few more specific child-finding functions

2018-11-29T16:30:05+00:00

Add two functions which can find a child device by uclass or by name.
The first is useful with Multi-Function-Devices (MFDs) to find one of a
particular type. The second is useful when only the name is known.
