| Subject: bus: ti-sysc: AM3: RNG is GP only |
| |
| From: Kevin Hilman <khilman@baylibre.com> |
| |
| commit a6d90e9f22328f07343e49e08a4ca483ae8e8abb upstream. |
| |
| 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. |
