Add new DT binding for Texas Instruments DTHE V2 crypto driver. DTHE V2 is introduced as a part of TI AM62L SoC and can currently be only found in it. Signed-off-by: T Pratham <t-pratham@xxxxxx> --- PS: Please note that the dmas option in dt-bindings is subject to change in future as dma driver is not finalized yet. Any updated changes will be sent in the next version of the patch. .../devicetree/bindings/crypto/ti,dthev2.yaml | 50 ++++++++++++++++++++++ MAINTAINERS | 6 +++ 2 files changed, 56 insertions(+) diff --git a/Documentation/devicetree/bindings/crypto/ti,dthev2.yaml b/Documentation/devicetree/bindings/crypto/ti,dthev2.yaml new file mode 100644 index 0000000000000000000000000000000000000000..9c871fe191ae0a3341d047d4565ec1e1bf1f21ef --- /dev/null +++ b/Documentation/devicetree/bindings/crypto/ti,dthev2.yaml @@ -0,0 +1,50 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/crypto/ti,dthev2.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: K3 SoC DTHE V2 crypto module + +maintainers: + - T Pratham <t-pratham@xxxxxx> + +properties: + compatible: + enum: + - ti,dthe-v2 + + reg: + maxItems: 1 + + dmas: + items: + - description: 'AES Engine RX DMA Channel' + - description: 'AES Engine TX DMA Channel' + - description: 'SHA Engine TX DMA Channel' + + dma-names: + items: + - const: rx + - const: tx1 + - const: tx2 + + +required: + - compatible + - reg + - dmas + - dma-names + +additionalProperties: false + +examples: + - | + + crypto: crypto@40800000 { + compatible = "ti,dthe-v2"; + reg = <0x00 0x40800000 0x00 0x10000>; + + dmas = <&main_bcdma 0 0xc701 0>, <&main_bcdma 0 0x4700 0>, <&main_bcdma 0 0xc700 0>; + dma-names = "tx", "rx", "tx2"; + }; diff --git a/MAINTAINERS b/MAINTAINERS index 0d65aa9093f63ed8f09bee3d6f31fe6d8e0d16b6..e3a32533cf3922d799439b14453248d23350bb18 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -23433,6 +23433,12 @@ S: Odd Fixes F: drivers/clk/ti/ F: include/linux/clk/ti.h +TI DATA TRANSFORM AND HASHING ENGINE (DTHE) V2 CRYPTO ACCELERATOR DRIVER +M: T Pratham <t-pratham@xxxxxx> +L: linux-crypto@xxxxxxxxxxxxxxx +S: Supported +F: Documentation/devicetree/bindings/crypto/ti,dthe-v2.yaml + TI DAVINCI MACHINE SUPPORT M: Bartosz Golaszewski <brgl@xxxxxxxx> L: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx (moderated for non-subscribers) -- 2.34.1
