crypto: ccree - update register handling macros

2020-03-12T12:00:16Z

Changed CC_GENMASK macro so it can be used for all HW registers. Signed-off-by: Hadar Gat Signed-off-by: Herbert Xu

crypto: ccree - remove struct cc_cipher_handle

2020-02-22T01:25:45Z

The cc_cipher_handle structure contains only a single member, and only one instance exists. Simplify the code and reduce memory consumption by moving this member to struct cc_drvdata. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - simplify Runtime PM handling

2020-02-22T01:25:44Z

Currently, a large part of the probe function runs before Runtime PM is enabled. As the driver manages the device's clock manually, this may work fine on some systems, but may break on platforms with a more complex power hierarchy. Fix this by moving the initialization of Runtime PM before the first register access (in cc_wait_for_reset_completion()), and putting the device to sleep only after the last access (in cc_set_ree_fips_status()). This allows to remove the pm_on flag, which was used to track manually if Runtime PM had been enabled or not. Remove the cc_pm_{init,go,fini}() wrappers, as they are called only once, and obscure operation. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - use u32 for SRAM addresses

2020-02-22T01:25:44Z

SRAM addresses are small integer offsets into local SRAM. Currently they are stored using a mixture of cc_sram_addr_t (u64), u32, and dma_addr_t types. Settle on u32, and remove the cc_sram_addr_t typedefs. This allows to drop several casts. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - clean up clock handling

2020-02-22T01:25:43Z

Use devm_clk_get_optional() instead of devm_clk_get() and explicit optional clock handling. As clk_prepare_enable() and clk_disable_unprepare() handle optional clocks fine, the cc_clk_on() and cc_clk_off() wrappers can be removed. While at it, use the new "%pe" format specifier to print error codes. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - split overloaded usage of irq field

2020-01-22T08:21:10Z

We were using the irq field of the drvdata struct in an overloaded fahsion - saving the IRQ number during init and then storing the pending itnerrupt sources during interrupt in the same field. This worked because these usage are mutually exclusive but are confusing. So simplify the code and change the init use case to use a simple local variable.
