crypto: atmel-sha204a - add reading from otp zone

2024-05-10T09:15:25+00:00

Provide a read function reading the otp zone. The otp zone can be used for
storing serial numbers. The otp zone, as also data zone, are only
accessible if the chip was locked before. Locking the chip is a post
production customization and has to be done manually i.e. not by this
driver. Without this step the chip is pretty much not usable, where
putting or not putting data into the otp zone is optional.

crypto: atmel-i2c - rename read function

2024-05-10T09:15:25+00:00

Make the memory read function name more specific to the read memory zone.
The Atmel SHA204 chips provide config, otp and data zone. The implemented
read function in fact only reads some fields in zone config. The function
renaming allows for a uniform naming scheme when reading from other memory
zones.

crypto: atmel - Drop unused id parameter from atmel_i2c_probe()

2023-02-10T09:20:19+00:00

id is unused in atmel_i2c_probe() and the callers have extra efforts to
determine the right parameter. So drop the parameter simplifying both
atmel_i2c_probe() and its callers.

crypto: atmel-i2c - avoid defines prefixed with CONFIG

2023-01-20T10:29:31+00:00

Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.

Here, a definition for the driver's configuration zone is named
CONFIG_ZONE. Rename this local definition to CONFIGURATION_ZONE to avoid
defines prefixed with "CONFIG".

No functional change.

crypto: atmel - Avoid flush_scheduled_work() usage

2022-05-06T10:16:55+00:00

Flushing system-wide workqueues is dangerous and will be forbidden.
Replace system_wq with local atmel_wq.

If CONFIG_CRYPTO_DEV_ATMEL_{I2C,ECC,SHA204A}=y, the ordering in Makefile
guarantees that module_init() for atmel-i2c runs before module_init()
for atmel-ecc and atmel-sha204a runs.

error_list is only used in atmel-i2c.c,

crypto: atmel - Fix sparse endianness warnings

2019-06-06T06:38:57+00:00

The param2 member in atmel_i2c_cmd is supposed to be little-endian
but was marked as u16.  This patch changes it to a __le16 which
reveals a missing endian swap in atmel_i2c_init_read_cmd.

Another missing little-endian marking is also added in
atmel_i2c_checksum.
