Subject: [PATCH v4 2/5] ARM: bcm2835: add DT for the bcm2835 auxiliar devices
Date: Mon, 24 Aug 2015 08:40:05 +0000 [thread overview]
Message-ID: <1440405608-3995-3-git-send-email-kernel@martin.sperl.org> (raw)
In-Reply-To: <1440405608-3995-1-git-send-email-kernel@martin.sperl.org>
From: Martin Sperl <kernel@martin.sperl.org>
Add device tree definitions for auxiliar bcm2835 devices:
* spi1
* spi2
* uart1
This also include a device to get used by the relevant
device-drivers (via a shared register) to enable/disable
the HW-block.
