Subject: arasan,sdhci.txt "compatibility" DT binding
Date: Tue, 2 Feb 2016 10:49:25 +0100 [thread overview]
Message-ID: <56B07BA5.4060407@free.fr> (raw)
Hello everyone,
Documentation/devicetree/bindings/mmc/arasan,sdhci.txt states:
Required Properties:
- compatible: Compatibility string. Must be 'arasan,sdhci-8.9a' or
'arasan,sdhci-4.9a' or 'arasan,sdhci-5.1'
What do 8.9a, 4.9a, and 5.1 refer to?
$ git ls Documentation/devicetree/bindings/mmc/arasan,sdhci.txt
da795ec26e25 mmc: sdhci-of-arasan: Add the support for sdhci-5.1
308f3f8d8112 mmc: sdhci-of-arasan: Add the support for sdhci-arasan4.9a
e3ec3a3d11ad mmc: arasan: Add driver for Arasan SDHCI
I found two Arasan data sheets.
The first data sheet, created 2010-02-19, is titled
"SD3.0 / SDIO3.0 / eMMC4.4 AHB Host Controller"
and the documentation revision number is 6.0
The revision history mentions:
1.0 05.02.2005
1.1 02.08.2006
1.2 03.10.2006
1.3 03.27.2006
1.4 04.11.2006
1.5 04.18.2006
1.6 05.18.2006
1.7 06.05.2006
1.8 10.06.2006
1.9 19.06.2006
2.0 01.08.2007
2.1 01.30.2007
2.2 02.22.2007
2.3 04.30.2007
2.4 05.07.2007
2.5 06.04.2007
2.6 06.25.2007
2.7 06.29.2007
2.8 07.24.2007
2.9 07.31.2007
3.0 11.12.2007
3.1 11.14.2007
3.2 11.21.2007
3.3 12.13.2007
3.4 12.15.2007
3.5 04.11.2008
3.6 08.19.2008
3.7 10.11.2008
3.7a 11.11.2008
3.8a 11.25.2008
3.9a 01.22.2009
4.0a 02.13.2009
4.1a 04.06.2009
4.2a 06.16.2009
5.0 07.01.2009
5.1 07.13.2009
5.2 07.16.2009
5.3 07.29.2009
5.4 08.17.2009
5.5 08.29.2009
5.6 09.30.2009
5.7 11.04.2009
5.8 12.04.2009
5.9 01.19.2010
6.0 02.19.2010
The second data sheet, created 2012-09-07, is titled
"SD3.0 / SDIO3.0/ eMMC4.5 Host Controller"
and the documentation revision number is 1.13
Revision history mentions a "new architecture" for rev 1.0
in 2011-06-01
Neither of these data sheets mention anything about a 4.9a or 8.9a
version of the controller... And I don't think 5.1 refers to the
documentation rev, right?
So what do 8.9a, 4.9a, and 5.1 refer to?
Regards.
