On some boards, like omap5-uevm the MCLK is gated by default and in order to be able to use the High performance modes of twl6040 it need to be enabled by SW. Add support for handling the MCLK source clock via CCF. At the same time lower the print priority of the notification that the 32K clock is not provided and it is not going to be handled by the driver.

Texas Instruments TWL6040 family
|
|
|
|
The TWL6040s are 8-channel high quality low-power audio codecs providing audio,
|
|
vibra and GPO functionality on OMAP4+ platforms.
|
|
They are connected ot the host processor via i2c for commands, McPDM for audio
|
|
data and commands.
|
|
|
|
Required properties:
|
|
- compatible : "ti,twl6040" for twl6040, "ti,twl6041" for twl6041
|
|
- reg: must be 0x4b for i2c address
|
|
- interrupts: twl6040 has one interrupt line connecteded to the main SoC
|
|
- interrupt-parent: The parent interrupt controller
|
|
- gpio-controller:
|
|
- #gpio-cells = <1>: twl6040 provides GPO lines.
|
|
- twl6040,audpwron-gpio: Power on GPIO line for the twl6040
|
|
|
|
- vio-supply: Regulator for the twl6040 VIO supply
|
|
- v2v1-supply: Regulator for the twl6040 V2V1 supply
|
|
|
|
Optional properties, nodes:
|
|
- enable-active-high: To power on the twl6040 during boot.
|
|
- clocks: phandle to the clk32k and/or to mclk clock provider
|
|
- clock-names: Must be "clk32k" for the 32K clock and "mclk" for the MCLK.
|
|
|
|
Vibra functionality
|
|
Required properties:
|
|
- vddvibl-supply: Regulator for the left vibra motor
|
|
- vddvibr-supply: Regulator for the right vibra motor
|
|
- vibra { }: Configuration section for vibra parameters containing the following
|
|
properties:
|
|
- ti,vibldrv-res: Resistance parameter for left driver
|
|
- ti,vibrdrv-res: Resistance parameter for right driver
|
|
- ti,viblmotor-res: Resistance parameter for left motor
|
|
- ti,viblmotor-res: Resistance parameter for right motor
|
|
|
|
Optional properties within vibra { } section:
|
|
- vddvibl_uV: If the vddvibl default voltage need to be changed
|
|
- vddvibr_uV: If the vddvibr default voltage need to be changed
|
|
|
|

|
|
