ARM: i.MX31: remove rnga registration as a platform device (08a213c2) · Commits · 戴 / test

On i.MX31 powered boards with OF support Security Random Number Generator Accelerator RNGA controller is initialized from device tree, its registration as a platform device is redundant and actually it is broken due to missing clock information: mxc_rnga mxc_rnga: Could not get rng_clk! mxc_rnga: probe of mxc_rnga failed with error -2 Signed-off-by:
