From d953ada493711363d5b7f2151100c242923fc56b Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Thu, 7 Aug 2014 17:41:44 -0700 Subject: [PATCH] NFC: trf7970a: Document the 'irq-status-read-quirk' DT property The mechanism for specifying that the trf7970a being used by the driver has the "IRQ Status Read" erratum has been changed to a device tree property ('irq-status-read-quirk'). Document the new device tree property. Signed-off-by: Mark A.
