Subject: [PATCHv2 1/2] arm: samsung: support the second capability for samsung-soc
Date: Thu, 03 Nov 2011 11:35:58 +0900 [thread overview]
Message-ID: <4EB1FE0E.5070902@samsung.com> (raw)
In mmc, there are capabilities and use the host_caps.
That capability is expressed with bit[0:31].
But now..already filled the bit[0:31]...
so we need to denote with the other capability field.
(if we want to use the cache, powerclass, etc for eMMC..this field is necessary)
