Update all the Tegra DT bindings to require the standard dmas/dma-names properties rather than non-standard nvidia,dma-request-selector property. This is a DT-ABI-incompatible change. It is the second of two changes required for me to consider the Tegra DT bindings as stable, the other being the previous conversion to the common reset bindings.

Required properties:
|
|
- compatible : "nvidia,tegra20-i2s"
|
|
- reg : Should contain I2S registers location and length
|
|
- interrupts : Should contain I2S interrupt
|
|
- resets : Must contain an entry for each entry in reset-names.
|
|
See ../reset/reset.txt for details.
|
|
- reset-names : Must include the following entries:
|
|
- i2s
|
|
- dmas : Must contain an entry for each entry in clock-names.
|
|
See ../dma/dma.txt for details.
|
|
- dma-names : Must include the following entries:
|
|
- rx
|
|
- tx
|
|
- clocks : Must contain one entry, for the module clock.
|
|
See ../clocks/clock-bindings.txt for details.
|

Example:
|
|
|
|
i2s@70002800 {
|
|
compatible = "nvidia,tegra20-i2s";
|
|
reg = <0x70002800 0x200>;
|
|
interrupts = < 45 >;
|
|
clocks = <&tegra_car 11>;
|
|
resets = <&tegra_car 11>;
|
|
reset-names = "i2s";
|
|
dmas = <&apbdma 21>, <&apbdma 21>;
|
|
dma-names = "rx", "tx";
|
