crypto: ccree - avoid out-of-range warnings from clang

2021-11-18T18:16:30+00:00

[ Upstream commit cfd6fb45cfaf46fa9547421d8da387dc9c7997d4 ] clang points out inconsistencies in the FIELD_PREP() invocation in this driver that result from the 'mask' being a 32-bit value: drivers/crypto/ccree/cc_driver.c:117:18: error: result of comparison of constant 18446744073709551615 with expression of type 'u32' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare] cache_params |= FIELD_PREP(mask, val); ^~~~~~~~~~~~~~~~~~~~~ include/linux/bitfield.h:94:3: note: expanded from macro 'FIELD_PREP' __BF_FIELD_CHECK(_mask, 0ULL, _val, "FIELD_PREP: "); \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/bitfield.h:52:28: note: expanded from macro '__BF_FIELD_CHECK' BUILD_BUG_ON_MSG((_mask) > (typeof(_reg))~0ull, \ ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This does not happen in other places that just pass a constant here. Work around the warnings by widening the type of the temporary variable.

crypto: ccree - Remove redundant dev_err call in init_cc_resources()

2021-04-16T11:16:32+00:00

There is a error message within devm_ioremap_resource already, so remove the dev_err call to avoid redundant error message. Signed-off-by: YueHaibing Signed-off-by: Herbert Xu

crypto: ccree - fix spelling typo of allocated

crypto: ccree - remove unused including

2021-01-02T21:41:35+00:00

Remove including that don't need it. Signed-off-by: Tian Tao Signed-off-by: Herbert Xu

crypto: ccree - rework cache parameters handling

2020-11-27T06:13:49+00:00

Rework the setting of DMA cache parameters, program more appropriate values and explicitly set sharability domain. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - Fix fall-through warnings for Clang

2020-11-27T06:13:46+00:00

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly adding multiple break statements instead of letting the code fall through to the next case.

crypto: sha - split sha.h into sha1.h and sha2.h

2020-11-20T03:45:33+00:00

Currently contains declarations for both SHA-1 and SHA-2, and contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split into two headers and , and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

crypto: ccree - Simplify with dev_err_probe()

2020-09-04T07:57:16+00:00

Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Herbert Xu

crypto: ccree - fix runtime PM imbalance on error

2020-08-28T06:58:30+00:00

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. However, users of cc_pm_get(), a direct wrapper of pm_runtime_get_sync(), assume that PM usage counter will not change on error. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.
