Message-ID: <08233ba82c96ccf7d66e06f238f67282.squirrel@www.codeaurora.org> (raw)
In-Reply-To: <1427812635-16617-3-git-send-email-ygardi@codeaurora.org>
> Some implementation of UFS host controller HW might have some non-standard
> behaviours (quirks) when compared to behaviour specified by UFSHCI
> specification. This patch add support to allow specifying all such quirks
> to standard UFS host controller driver so standard driver takes them into
> account.
>
> In this change a UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS is introduced,
> where a minimum delay of 1ms is required before DME commands for
> stability purposes.
