hwrng: omap - Add device tree support
Add Device Tree suport to the omap-rng driver. Currently, only support for OMAP2 and OMAP3 is being added but support for OMAP4 and OMAP5 will be added in a subsequent patch. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
