Make the RNG on AM3 GP only. Based on this patch from TI v5.4 tree which is based on hwmod data which are now removed: | ARM: AM43xx: hwmod: Move RNG to a GP only links table | | On non-GP devices the RNG is controlled by the secure-side software, | like in DRA7xx hwmod we should not control this IP when we are not | a GP device. | | Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com> --- If this is merged, it should be flagged for stable v5.10+. drivers/bus/ti-sysc.c | 2 ++ 1 file changed, 2 insertions(+)
