Subject: [PATCH v7 0/4] Add dual-fifo mode support of i.MX ssi
Date: Wed, 13 Nov 2013 22:55:23 +0800 [thread overview]
Message-ID: <cover.1384352281.git.b42378@freescale.com> (raw)
* ! This series of patches has a direct dependency between them. When
* ! applying them, we need to apply to one single branch. Otherwise,
* ! it would break currect branches.
Changelog
v7:
* Appended missing Acked-by to all four patches.
* Sorry that I didn't add them at the first place.
v6:
* PATCH-1: Use goto err_firmware instead of return directly.
*
* Nothing changes for the other three ack-ed patches
v5:
* PATCH-3: Add period size constraint when using dual fifo mode
*
* Nothing changes for the other three patches
v4:
* PATCH-3: Drop useless register configuration.
*
* Nothing changes for the other three patches
v3:
* PATCH-1: Add comments to indicate the end of v1 and v2 array.
* PATCH-3: Use better way to keep watermark as even number.
*
* Nothing changes for PATCH-2 and PATCH-4
v2:
* Instead of adding rogue scripts to current SDMA driver based on firmware
* V1, we define the new SDMA firmware as version 2 and bisect the PATCH-1
* to two patches: The first is to add version check code to the SDMA driver;
* And the second is to add SSI dual FIFO DMATYPE.
*
* Nothing changes for the last two patches.
v1:
* SSI can reduce hardware overrun/underrun possibility when using dual
* fifo mode. To support this mode, we need to first update sdma sciprt
* list, and then enable dual fifo BIT in SSI driver, and last update DT
* bindings of i.MX series.
