across several different platforms and architectures, fixes to existing drivers, a MAINTAINERS file fix and improvements to the basic clock types that allow them to be of use to more platforms than before.

TI-NSPIRE Clocks
|
||||
|
||||
Required properties:
|
||||
- compatible: Valid compatible properties include:
|
||||
"lsi,nspire-cx-ahb-divider" for the AHB divider in the CX model
|
||||
"lsi,nspire-classic-ahb-divider" for the AHB divider in the older model
|
||||
"lsi,nspire-cx-clock" for the base clock in the CX model
|
||||
"lsi,nspire-classic-clock" for the base clock in the older model
|
||||
|
||||
- reg: Physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
|
||||
Optional:
|
||||
- clocks: For the "nspire-*-ahb-divider" compatible clocks, this is the parent
|
||||
clock where it divides the rate from.
|
||||
|
||||
Example:
|
||||
|
||||
ahb_clk {
|
||||
#clock-cells = <0>;
|
||||
compatible = "lsi,nspire-cx-clock";
|

reg = <0x900B0000 0x4>;

clocks = <&base_clk>;

Device Tree Clock bindings for arch-rockchip
|
||||
|
||||
This binding uses the common clock binding[1].

||||
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||||
|
||||
== Gate clocks ==
|
||||
|
||||
The gate registers form a continuos block which makes the dt node
|
||||
structure a matter of taste, as either all gates can be put into
|
||||
one gate clock spanning all registers or they can be divided into
|
||||
the 10 individual gates containing 16 clocks each.
|
||||
The code supports both approaches.
|
||||
|
||||
Required properties:
|
||||
- compatible : "rockchip,rk2928-gate-clk"
|
||||
- reg : shall be the control register address(es) for the clock.
|
||||
- #clock-cells : from common clock binding; shall be set to 1
|
||||
- clock-output-names : the corresponding gate names that the clock controls
|
||||
- clocks : should contain the parent clock for each individual gate,
|
||||
therefore the number of clocks elements should match the number of
|
||||
clock-output-names
|
||||
|
||||
Example using multiple gate clocks:
