clk: clk-cdce925: Add regulator support

2019-09-06T17:31:16+00:00

The cdce925 power supplies could be controllable on some platforms.
Enable them before communicating with the cdce925.

Merge branches 'clk-dt-name', 'clk-ti-of-node' and 'clk-sa' into clk-next

2018-10-18T22:33:52+00:00

  - Use updated printk format for OF node names
  - Fix TI code to only search DT subnodes
  - Various static analysis finds

* clk-dt-name:
  clk: Convert to using %pOFn instead of device_node.name

* clk-ti-of-node:
  clk: ti: fix OF child-node lookup

* clk-sa:
  clk: mvebu: armada-37xx-tbg: Switch to clk_get and balance it in probe
  reset: hisilicon: fix potential NULL pointer dereference
  clk: cdce925: release child device nodes
  clk: qcom: clk-branch: Use true and false for boolean values

clk: cdce925: release child device nodes

2018-08-30T22:19:16+00:00

of_get_child_by_name() returns device node with refcount incremented,
but there is no decrement in cdce925_probe(). The patch adds one.

clk: Convert to using %pOFn instead of device_node.name

2018-08-30T16:50:20+00:00

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

clk: cdce925: remove redundant check for non-null parent_name

2017-11-14T01:44:15+00:00

The check for a non-null parent_name is always true as there is an
earlier check for a null parent_name that returns -ENODEV. Remove this
redundant check and always set init.num_parents to 1.

clk: cdce925: add support for CDCE913, CDCE937, and CDCE949

2017-01-10T00:38:30+00:00

The CDCE925 is a member of the CDCE(L)9xx programmable clock generator
family.  There are also CDCE913, CDCE937, CDCE949 which have different
number of PLLs and outputs.

The clk-cdce925 driver supports only CDCE925 in the family.  This adds
support for the CDCE913, CDCE937, CDCE949, too.

clk: cdce925: Fix limit check

2016-12-09T00:29:36+00:00

It is likely that instead of '1>64', 'q>64' was expected.

Moreover, according to datasheet,
   http://www.ti.com/lit/ds/symlink/cdce925.pdf
   SCAS847I - JULY 2007 - REVISED OCTOBER 2016
PLL settings limits are: 16 <= q <= 63
So change the upper limit check from 64 to 63.

clk: cdce925: Migrate to clk_hw based OF and provider APIs

2016-08-25T00:18:13+00:00

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

clk: cdce925: Include clk.h

2015-07-20T18:11:32+00:00

This clock provider uses the consumer API, so include clk.h
explicitly.
