crypto: mxs - Add Freescale MXS DCP driver
Add support for the MXS DCP block. The driver currently supports SHA-1/SHA-256 hashing and AES-128 CBC/ECB modes. The non-standard CRC32 is not yet supported.

Freescale DCP (Data Co-Processor) found on i.MX23/i.MX28 .
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible : Should be "fsl,<soc>-dcp"
|
||||||
|
- reg : Should contain MXS DCP registers location and length
|
||||||
|
- interrupts : Should contain MXS DCP interrupt numbers, VMI IRQ and DCP IRQ
|
||||||
|
must be supplied, optionally Secure IRQ can be present, but
|
||||||
|
is currently not implemented and not used.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
dcp@80028000 {
|
||||||
|
compatible = "fsl,imx28-dcp", "fsl,imx23-dcp";
|
||||||
|
reg = <0x80028000 0x2000>;
|
||||||
|
interrupts = <52 53>;
|
||||||
|
status = "okay";
