CAAM support on imx6sl-evk board

Hi Experts,

Do we have Linux CAAM driver support on imx6sl-evk board , as I can not see any entry in .dts file. Please help.

The i.MX6SoloLite processor does not contain the CAAM module in its SoC hardware by its design, so, there is no CAAM support in software for it.

Have a great day,
Artur

Thanks Artur,

Thanks a lot for your response.  

Artur ,We want to use RNG hardware module available on imx6sl for our use-case. Currently we trying with below changes:-

Kernel Flags enabled:-

CONFIG_HW_RANDOM=y

CONFIG_HAVE_IMX_RNG=y

            CONFIG_HW_RANDOM_IMX_RNG=y

Device Tree:-

rng: rng@021b4000 {

                compatible = "fsl,imx6sl-rng", "fsl,imx-rng", "imx-rng";

                reg = <0x021b4000 0x4000>;

                interrupts = <0 5 IRQ_TYPE_LEVEL_HIGH>;

                clocks = <&clks IMX6SL_CLK_DUMMY>;

            };

Then we are going to use rngtest to testing purpose. Please let me know if I am missing something here.
