[PATCH 0/8] Clock changes for TI dts reg and node name issues

[PATCH 0/8] Clock changes for TI dts reg and node name issues

[Tony Lindgren]

Hi all,

Here are TI clock changes that allow us to update the devicetree files to
use clock-output-names instead of non-standard node names for clocks.

The related devicetree binding changes have been sent and are the
folloing patches:

[PATCHv2] dt-bindings: clock: Add binding for TI clksel
[PATCH 1/3] dt-bindings: omap: Add clock-output-names and #clock-cells

In addition to these changes, also devicetree changes are needed. Some
SoCs also need patches to unify the internal clock names. I'll be
sending those out separately.

Regards,

Tony

[PATCH 1/8] clk: ti: Constify clkctrl_name

[Tony Lindgren]

We can constify clkctrl_name in preparation for making use of the
clock-output-names property.

[PATCH 2/8] clk: ti: Preserve node in ti_dt_clocks_register()

[Tony Lindgren]

In preparation for making use of the clock-output-names, we want to
keep node around in ti_dt_clocks_register().

This change should not needed as a fix currently.

[PATCH 3/8] clk: ti: Optionally parse IO address from parent clock node

[Tony Lindgren]

If no reg property is specified for a TI clock, let's try to use the
parent clock node IO address. This way we can avoid duplicate devicetree
reg properties that cause warnings for unique_unit_address.
