crypto: rockchip - Fix dma_unmap_sg() nents value

2025-10-29T13:04:30+00:00

[ Upstream commit 21140e5caf019e4a24e1ceabcaaa16bd693b393f ] The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned. Fixes: 57d67c6e8219 ("crypto: rockchip - rework by using crypto_engine") Cc: Signed-off-by: Thomas Fourier Signed-off-by: Herbert Xu [ removed unused rctx variable declaration since device pointer already came from tctx->dev->dev instead of rctx->dev ] Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

crypto: rockchip - rework by using crypto_engine

2022-12-31T12:32:31+00:00

[ Upstream commit 57d67c6e8219b2a034c16d6149e30fb40fd39935 ] Instead of doing manual queue management, let's use the crypto/engine for that. In the same time, rework the requests handling to be easier to understand (and fix all bugs related to them).

[ Upstream commit bb3c7b73363c9a149b12b74c44ae94b73a8fddf8 ] Now driver have fallback for un-aligned cases, remove all code handling those cases.

crypto: rockchip - better handle cipher key

2022-12-31T12:32:30+00:00

[ Upstream commit d6b23ccef82816050c2fd458c9dabfa0e0af09b9 ] The key should not be set in hardware too much in advance, this will fail it 2 TFM with different keys generate alternative requests. The key should be stored and used just before doing cipher operations.

[ Upstream commit 68ef8af09a1a912a5ed2cfaa4cca7606f52cef90 ] The hardware does not handle 0 size length request, let's add a fallback. Furthermore fallback will be used for all unaligned case the hardware cannot handle.

[ Upstream commit 87e356c4966444866186f68f05832fdcc0f351a3 ] Storing the mode globally does not work if 2 requests are handled in the same time. We should store it in a request context.

crypto: rockchip - do not do custom power management

[ Upstream commit c50ef1411c8cbad0c7db100c477126076b6e3348 ] The clock enable/disable at tfm init/exit is fragile, if 2 tfm are init in the same time and one is removed just after, it will leave the hardware uncloked even if a user remains. Instead simply enable clocks at probe time. We will do PM later.
