dm: implement a MTD uclass

2015-11-12T00:26:58+00:00

Implement a Memory Technology Device (MTD) uclass. It should
include most flash drivers in the future. Though no uclass ops
are defined yet, the MTD ops could be used.

The NAND flash driver is based on MTD. The CFI flash and SPI
flash support MTD, too. It should make sense to convert them
to MTD uclass.

dm: adc: add simple ADC uclass implementation

2015-11-02T01:38:00+00:00

This commit adds:
- new uclass id: UCLASS_ADC
- new uclass driver: drivers/adc/adc-uclass.c

The new uclass's API allows for ADC operation on:
* single-channel with channel selection by a number
* multti-channel with channel selection by bit mask

ADC uclass's functions:
* single-channel:
  - adc_start_channel()        - start channel conversion
  - adc_channel_data()         - get conversion data
  - adc_channel_single_shot()  - start/get conversion data
* multi-channel:
  - adc_start_channels()       - start selected channels conversion
  - adc_channels_data()        - get conversion data
  - adc_channels_single_shot() - start/get conversion data for channels
                                 selected by bit mask
* general:
  - adc_stop()      - stop the conversion
  - adc_vdd_value() - positive reference Voltage value with polarity [uV]
  - adc_vss_value() - negative reference Voltage value with polarity [uV]
  - adc_data_mask() - conversion data bit mask

The device tree can provide below constraints/properties:
- vdd-polarity-negative: if true: Vdd = vdd-microvolts * (-1)
- vss-polarity-negative: if true: Vss = vss-microvolts * (-1)
- vdd-supply:            phandle to Vdd regulator's node
- vss-supply:            phandle to Vss regulator's node
And optional, checked only if the above corresponding, doesn't exist:
  - vdd-microvolts:      positive reference Voltage [uV]
  - vss-microvolts:      negative reference Voltage [uV]

dm: core: Tidy up comments in device.h

2015-10-23T15:42:28+00:00

Correct a few nits found in a recent review. Expand the comments in
dev_get_driver_data() to make it clearer.

dm: core: Remove a comment about dropping per_child_auto_alloc_size

2015-10-23T15:42:28+00:00

This has proven useful and we no-longer intend to remove it. Drop the
comment.

dm: core: Tidy up devres comments

2015-10-23T15:42:28+00:00

Adjust the devres comments to be consistent with the rest of the file, and
add one for the struct udevice member. Also rename the 'p' parameter to
'ptr' to avoid single-character names.

dm: Rename dev_get_parentdata() to dev_get_parent_priv()

2015-10-23T15:42:28+00:00

The current name is inconsistent with other driver model data access
functions. Rename it and fix up all users.

dm: implement a Miscellaneous uclass

2015-10-22T23:37:03+00:00

Implement a Miscellaneous uclass with generic read or
write operations. This class is used only for those
do not fit other more general classes.
