Subject: [PATCH] ldp: Fix regulator mapping for ads7846 TS controller
Date: Thu, 24 Feb 2011 18:26:42 +0530	[thread overview]
Message-ID: <1298552202-28307-1-git-send-email-rnayak@ti.com> (raw)

On the OMAP3430LDP board, the ads7846 touchscreen controller
is powered by VAUX1 regulator (supplying 3.0v).
Fix this mapping in the board file, and hence prevent
the ads7846 driver init to fail with the below error..

ads7846 spi1.0: unable to get regulator: -19
