Subject: [PATCH] ARM: BCM5301X: Add DT entry for SPI controller and NOR flash
Date: Tue, 19 Apr 2016 08:56:46 +0200 [thread overview]
Message-ID: <1461049006-22818-1-git-send-email-zajec5@gmail.com> (raw)
Controller is present on every BCM4708* board but only few devices have
serial flash attached so mark it as disabled by default.
