clk: convert API to match reset/mailbox style

2016-06-19T23:05:55+00:00

The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

at91: video: Support driver-model for the LCD driver

2016-06-12T21:49:38+00:00

Add driver-model support to this driver. Most features can be controlled
from the device tree.

at91: video: Prepare for driver-model conversion

2016-06-12T21:49:38+00:00

Adjust the driver to use struct display_timing for its display timing.
This is what is used by driver-model and allows the LCD init code to be
common.

Now that we are using driver model, we can drop the weak functions and LCD
init in the board file.

exynos: video: Convert several boards to driver model for video

2016-05-25T04:25:19+00:00

Update several boards to use driver model for video. This involves changes
to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration
since they use the device tree settings in the same way as Linux.

Boards converted are:
- snow
- spring
- peach-pit
- peach-pi

All have been tested. Not converted:

- MIPI display driver
- s5pc210_universal
- smdk5420
- smdk5250
- trats
- trats2
