Subject: [PATCH 19/49] crypto: rockchip: do not do custom power management
The clock enable/disable at tfm init/exit is fragile,
if 2 tfm are init in the same time and one is removed just after,
it will leave the hardware uncloked even if a user remains.
Instead simply enable clocks at probe time.
We will do PM later.

Subject: [PATCH 22/49] crypto: rockchip: add fallback for cipher
The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

The key should not be set in hardware too much in advance, this will
fail it 2 TFM with different keys generate alternative requests.
The key should be stored and used just before doing cipher operations.

Subject: [PATCH 26/49] crypto: rockchip: rework by using crypto_engine
Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")
Reviewed-by: John Keeping <john@metanate.com>

Subject: [PATCH 27/49] crypto: rockchip: rewrite type
Instead of using a custom type for classify algorithms, let's just use
already defined ones.
And let's made a bit more verbose about what is registered.

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

Subject: [PATCH 38/49] crypto: rockchip: use a rk_crypto_info variable instead
of lot of indirection
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.

RK3399 has 2 crypto instance, named crypto0 and crypto1 in the TRM.
Only reset for crypto1 is correctly named, but crypto0 is not.
Since nobody use them , add a 0 to be consistent with the TRM and crypto1 entries.

Subject: [PATCH 46/49] crypto: rockchip: Check for clocks numbers and their
frequencies
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.

The RK3399 has 3 resets, so the driver to handle multiple resets.
This is done by using devm_reset_control_array_get_exclusive().

Subject: [PATCH 49/49] crypto: rockchip: Add support for RK3399
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.
