Subject: [PATCH] ARM: PCM970: Add definition for SPI CS1
Date: Wed, 8 May 2013 11:34:38 +0400 [thread overview]
Message-ID: <1367998478-9314-1-git-send-email-shc_work@mail.ru> (raw)
This chipselect is used on RDK Zigbee connector. Since we cannot
define additional chipselect after SPI is initialized, define this one
in main SPI initialization in PCM038 SOM.
