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

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.

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().

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.

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.

crypto: rockchip - store crypto_info in request context

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

The crypto_info to use must be stored in the request context.
This will help when 2 crypto_info will be available on rk3399.

crypto: rockchip - use the rk_crypto_info given as parameter

2022-10-28T04:36:33+00:00

Instead of using the crypto_info from TFM ctx, use the one given as parameter.

crypto: rockchip - use a rk_crypto_info variable instead of lot of indirection

2022-10-28T04:36:33+00:00

Instead of using lot of ctx->dev->xx indirections, use an intermediate
variable for rk_crypto_info.
This will help later, when 2 different rk_crypto_info would be used.

crypto: rockchip - rework rk_handle_req function

2022-10-28T04:36:33+00:00

crypto: rockchip - rename ablk functions to cipher

2022-10-28T04:36:33+00:00

Some functions have still ablk in their name even if there are
not handling ablk_cipher anymore.
So let's rename them.
