Describe and enable the AES, SHA and TDES crypto IPs. Tested with the extra run-time self tests of the registered crypto algorithms. Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> --- v3: remove explicit status = "okay", as it's already the default case when not specified at all. v2: - add label to the tdes node - update commit description and specify testing method - put clocks and clock-names properties before dmas and dma-names because the clocks are mandatory, while DMA is optional for TDES and SHA arch/arm/boot/dts/sama7g5.dtsi | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+)
