crypto: sa2ul - Return crypto_aead_setkey to transfer the error

2024-01-25T23:27:21+00:00

[ Upstream commit ce852f1308ac738e61c5b2502517deea593a1554 ] Return crypto_aead_setkey() in order to transfer the error if it fails. Fixes: d2c8ac187fc9 ("crypto: sa2ul - Add AEAD algorithm support") Signed-off-by: Chen Ni Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: sa2ul - Check engine status before enabling

2022-07-15T08:43:22+00:00

There is a engine status register that can be used to check if the different HW crypto engines are enabled. Check that first and then only try to enable the engines if they are not already on. This has a couple benefits. First we don't need to use match_data for this. Second, this driver can now work on HS devices where the engine control registers are read-only and writing causes a firewall exception. Signed-off-by: Andrew Davis Signed-off-by: Herbert Xu

crypto: sa2ul - Set the supported_algos bits individually

2022-07-15T08:43:22+00:00

Setting these individually gives a better picture of supported functions at a glance. Plus if the list changes an unwanted one will not accidentally get set with GENMASK. Signed-off-by: Andrew Davis Signed-off-by: Herbert Xu

crypto: sa2ul - Add the new compatible for AM62

Add the new compatible for am62x in of_match_table. Signed-off-by: Jayesh Choudhary Signed-off-by: Herbert Xu

crypto: sa2ul - Use bitfield helpers

2021-12-03T04:56:17+00:00

Use the FIELD_PREP() helper, instead of open-coding the same operation. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: sa2ul - Use the defined variable to clean code

2021-10-29T13:04:03+00:00

Use the defined variable "dev" to make the code cleaner. Signed-off-by: Tang Bin Signed-off-by: Herbert Xu

crypto: sa2ul - Remove unused auth_len variable

2021-06-24T06:51:34+00:00

This patch removes the unused auth_len variable from sa_aead_dma_in_callback. Reported-by: kernel test robot Signed-off-by: Herbert Xu

crypto: sa2ul - Remove child devices in remove

2021-05-23T00:52:40+00:00

The sa_ul_probe creates child devices using of_platform_populate(), but these are not cleaned up in driver remove. Clean these up by removing the child devices using of_platform_depopulate(). Signed-off-by: Suman Anna Reviewed-by: Tero Kristo Signed-off-by: Herbert Xu

crypto: sa2ul - Use devm_platform_ioremap_resource()

2021-05-23T00:52:40+00:00

Simplify the platform_get_resource() and devm_ioremap_resource() calls with devm_platform_ioremap_resource(). Also add error checking and move up this block to simplify the cleanup in sa_ul_probe(). Signed-off-by: Suman Anna Reviewed-by: Tero Kristo Signed-off-by: Herbert Xu

crypto: sa2ul - Use of_device_get_match_data() helper

2021-05-23T00:52:40+00:00

Simplify the probe function by using the of_device_get_match_data() helper instead of open coding. The logic is also moved up to fix the missing pm_runtime cleanup in case of a match failure.
