Subject: [PATCH 03/18] crypto: caam - fix writing to JQCR_MS when using service interface
Date: Mon,  3 Sep 2018 13:23:53 +0200	[thread overview]
Message-ID: <20180903112408.2086-4-m.niestroj@grinn-global.com> (raw)
In-Reply-To: <20180903112408.2086-1-m.niestroj@grinn-global.com>

Pick commit 9f587fa29f7e8ed6b8885cff51a51ace3ad85152 from Linux
upstream.

    crypto: caam - fix writing to JQCR_MS when using service interface

    Most significant part of JQCR (Job Queue Control Register) contains
    bits that control endianness: ILE - Immediate Little Endian,
    DWS - Double Word Swap.
    The bits are automatically set by the Job Queue Controller HW.

    Unfortunately these bits are cleared in SW when submitting descriptors
    via the register-based service interface.
    >From LS1021A:
    JQCR_MS = 08080100 - before writing: ILE | DWS | SRC (JR0)
    JQCR_MS = 30000100 - after writing: WHL | FOUR | SRC (JR0)

    This would cause problems on little endian caam for descriptors
    containing immediata data or double-word pointers.
    Currently there is no problem since the only descriptors ran through
    this interface are the ones that (un)instantiate RNG.
