of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the non-const structs as const.

When enable_single_wr is not enabled, the DSE will only write those parts of a result descriptor that need updating, which means a final result descriptor will be written in 2 or 3 smaller transfers. When enable_single_wr is enabled the DSE will combine these 2-3 updates into one large write transfer, generally improving performance. Signed-off-by:

The run-time self-tests fail quite early, as soon as the input block size is larger than 64 bytes: alg: hash: Test 4 failed for sha1-sun4i-ss 00000000: b9 c9 1e 52 c0 26 d8 39 81 ff f2 3c 99 b1 27 b2 00000010: 30 d6 c9 85 One thing to notice is the value of the last word, which is the one expected (it can sometime be the last two words). The datasheet isn't very clear about when the digest is ready to retrieve and is seems the bit SS_DATA_END is cleared when the digest was computed *but* that doesn't mean the digest is ready to retrieve in the registers. A ndelay(1) is added before reading the computed digest to ensure it is available in the SS_MD[] registers. Signed-off-by:
