[PATCH 0/4] hwrng: add support for i.MX6 rngb

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for RNGB found in some i.MX6 SoCs (6SL, 6SLL, 6ULL, 6ULZ),
based on RNGC driver (drivers/char/hw_random/imx-rngc.c).

This driver claims support also for RNGB (besides RNGC),
and is currently used only by i.MX25.

Note:

All the i.MX6 SoCs with RNGB have a DCP (Data Co-Processor)
crypto accelerator.

Several NXP SoC from QorIQ family (P1010, P1023, P4080, P3041, P5020)
also have a RNGB, however it's part of the CAAM
(Cryptograhic Accelerator and Assurance Module) crypto accelerator.
In this case, RNGB is managed in the caam driver
(drivers/crypto/caam/), since it's tightly related to
the caam "job ring" interface.
