Subject: [PATCH] crypto: atmel: Add capability case for the 0x600 SHA and AES IP versions
Date: Wed, 7 Dec 2022 15:59:55 +0200	[thread overview]
Message-ID: <20221207135953.136557-1-sergiu.moga@microchip.com> (raw)

In order for the driver to be made aware of the capabilities of the SHA
and AES IP versions 0x600 , such as those present on the SAM9X60 SoC's,
add a corresponding switch case to the capability method of the respective
drivers. Without this, besides the capabilities not being correctly set,
the self tests may hang since the driver is endlessly waiting for a
completion to be set by a never occurring DMA interrupt handler.
