Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

NVIDIA Tegra 20 AC97 controller
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra20-ac97"
|
|
- reg : Should contain AC97 controller registers location and length
|
|
- interrupts : Should contain AC97 interrupt
|
|
- clocks : Must contain one entry, for the module clock.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- resets : Must contain an entry for each entry in reset-names.
|
|
See ../reset/reset.txt for details.
|
|
- reset-names : Must include the following entries:
|
|
- ac97
|
|
- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
|
|
request selector for the AC97 controller
|
|
- nvidia,codec-reset-gpio : The Tegra GPIO controller's phandle and the number
|
|
of the GPIO used to reset the external AC97 codec
|
|
- nvidia,codec-sync-gpio : The Tegra GPIO controller's phandle and the number
|
|
of the GPIO corresponding with the AC97 DAP _FS line
|
|
|
|
Example:
|
|
|
|
ac97@70002000 {
|
|
compatible = "nvidia,tegra20-ac97";
|
|
reg = <0x70002000 0x200>;
|
|
interrupts = <0 81 0x04>;
|
|
nvidia,dma-request-selector = <&apbdma 12>;
|
|
nvidia,codec-reset-gpio = <&gpio 170 0>;
|
|
nvidia,codec-sync-gpio = <&gpio 120 0>;
|
|
clocks = <&tegra_car 3>;
|
|
resets = <&tegra_car 3>;
|
|
reset-names = "ac97";
|
|
};
