2024-10-28crypto: starfive - remove unneeded crypto_engine_stop() callOvidiu Panait
The explicit crypto_engine_stop() call is not needed, as it is already called internally by crypto_engine_exit(). Signed-off-by: Ovidiu Panait <ovidiu.panait.oss@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2024-10-19crypto: drivers - Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/crypto to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-04-02crypto: starfive - Use dma for aes requestsJia Jie Ho
Convert AES module to use dma for data transfers to reduce cpu load and compatible with future variants. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2024-04-02crypto: starfive - Update hash dma usageJia Jie Ho
Current hash uses sw fallback for non-word aligned input scatterlists. Add support for unaligned cases utilizing the data valid mask for dma. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-12-15crypto: starfive - Fix dev_err_probe return errorJia Jie Ho
Current dev_err_probe will return 0 instead of proper error code if driver failed to get irq number. Fix the return code. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-11-24crypto: starfive - RSA poll csr for done statusJia Jie Ho
Hardware could not clear irq status without resetting the entire module. Driver receives irq immediately when mask bit is cleared causing intermittent errors in RSA calculations. Switch to use csr polling for done status instead. Signed-off-by: Jia Jie Ho <jiajie.ho@starfivetech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-11-17crypto: jh7110 - Correct deferred probe returnChanho Park
This fixes list_add corruption error when the driver is returned with -EPROBE_DEFER. It is also required to roll back the previous probe sequences in case of deferred_probe. So, this removes 'err_probe_defer" goto label and just use err_dma_init instead.

2023-08-23crypto: drivers - Explicitly include correct DT includesRob Herring
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.

2023-07-28crypto: starfive - Add AES skcipher and aead supportJia Jie Ho
Adding AES skcipher and aead support to Starfive crypto module. Skcipher modes of operation include ecb, cbc, ctr, ofb, cfb. Aead modes include ccm and gcm. v1->v2: - Add include interrupt.h to fix compile error.

2023-07-20crypto: starfive - Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
