crypto: rockchip - Fix dma_unmap_sg() nents value

2025-10-19T14:30:49+00:00

commit 21140e5caf019e4a24e1ceabcaaa16bd693b393f upstream. The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned.

crypto: rk3288 - Fix use after free in unprepare

2024-04-03T13:28:40+00:00

commit c0afb6b88fbbc177fa322a835f874be217bffe45 upstream. The unprepare call must be carried out before the finalize call as the latter can free the request.

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

crypto: rk3288 - Use new crypto_engine_op interface

2023-08-18T09:01:11+00:00

Use the new crypto_engine_op interface where the callback is stored in the algorithm object. Signed-off-by: Herbert Xu

crypto: rk3288 - Remove prepare/unprepare request

2023-08-18T09:01:09+00:00

The callbacks for prepare and unprepare request in crypto_engine is superfluous. They can be done directly from do_one_request. Move the code into do_one_request and remove the unused callbacks. Signed-off-by: Herbert Xu

crypto: rockchip - Remove surplus dev_err() when using platform_get_irq()

2022-11-11T10:14:59+00:00

There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure. ./drivers/crypto/rockchip/rk3288_crypto.c:351:2-9: line 351 is redundant because platform_get_irq() already prints an error Link: https://bugzilla.openanolis.cn/show_bug.cgi?id=2677 Reported-by: Abaci Robot Signed-off-by: Yang Li Acked-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: rockchip - Add support for RK3399

2022-10-28T04:36:34+00:00

The RK3399 has 2 rk3288 compatible crypto device named crypto0 and crypto1. The only difference is lack of RSA in crypto1. We need to add driver support for 2 parallel instance as only one need to register crypto algorithms. Then the driver will round robin each request on each device. For avoiding complexity (device bringup after a TFM is created), PM is modified to be handled per request. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: rockchip - permit to have more than one reset

2022-10-28T04:36:34+00:00

The RK3399 has 3 resets, so the driver to handle multiple resets. This is done by using devm_reset_control_array_get_exclusive(). Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: rockchip - rk_ahash_reg_init use crypto_info from parameter

2022-10-28T04:36:34+00:00

rk_ahash_reg_init() use crypto_info from TFM context, since we will remove it, let's take if from parameters. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: rockchip - Check for clocks numbers and their frequencies

2022-10-28T04:36:34+00:00

Add the number of clocks needed for each compatible. Rockchip's datasheet give maximum frequencies for some clocks, so add checks for verifying they are within limits. Let's start with rk3288 for clock frequency check, other will came later. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu
