Revert "ns16650: Make sure we have CONFIG_CLK set before using infrastructure"

2016-10-08T13:33:31+00:00

This reverts commit 82f5279b0cd99a9163d34cfe926d0316d9dc0d37.

The build failure of k2*evm boards was fixed in a different way by
the previous commit.  It is nasty to patch generic drivers around
with #ifdef CONFIG_CLK just for the KeyStone's matter.

treewide: replace #include with

2016-09-23T21:55:42+00:00

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap )

Replace all include directives for  with .

ns16650: Make sure we have CONFIG_CLK set before using infrastructure

2016-09-22T19:39:11+00:00

We cannot call on the CONFIG_CLK based clk_get_rate function unless
CONFIG_CLK is set.

clk: Use dummy clk_get_by_* functions when CONFIG_CLK is disabled

2016-09-21T13:04:32+00:00

The implementations of clk_get_by_index & clk_get_by_name are only
available when CONFIG_CLK is enabled. Provide the dummies when this is
not the case in order to avoid build failures.

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).

dm: clk: Add support for decoding clocks from the device tree

2016-01-22T02:47:29+00:00

Add a method which can locate a clock for a device, given its index. This
uses the normal device tree bindings to return the clock device and the
first argument which is normally used as a peripheral ID in U-Boot.

clk: add API to enable clock

The most basic thing for clock is to enable it, but it is missing
