From mboxrd@z Thu Jan 1 00:00:00 1970 From: mw@semihalf.com (Marcin Wojtas) Date: Fri, 9 Oct 2015 03:03:53 +0200 Subject: [PATCH v2 3/5] ARM: mvebu: set SW polling as SDHCI card detection on A388-GP In-Reply-To: <1444352635-21965-1-git-send-email-mw@semihalf.com> References: <1444352635-21965-1-git-send-email-mw@semihalf.com> Message-ID: <1444352635-21965-4-git-send-email-mw@semihalf.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The newest revisions of A388-GP (v1.5 and higher) support only DAT3-based card detection. Revisions < v1.5 based on GPIO detection via I2C expander, but this solution is supposed to be deprecated on new boards. In order to satisfy all type of hardware this commit changes card detection to use software polling mechanism.
