Merge tag 'omap-for-v4.12/dt-pt2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

Second set of devicetree changes for omaps for v4.12 merge window to configure various devices: - Enable DCAN on am57xx-idk - Enable CPSW ethernet0 and 1 on am335x-icev2 - Non-critical fix for droid 4 PMIC interrupt triggering - Stop disabling SRAM and GPMC on droid 4 - Configure CPCAP PMIC related devices on droid 4 for ADC, charger and USB PHY. The charger and USB PHY drivers are still being discussed, but the binding for them has been acked by Rob and Sebastian so they should be safe to merge together with the ADC driver in Linux next that they depend on * tag 'omap-for-v4.12/dt-pt2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: omap4-droid4: Add CPCAP PMIC OTG PHY configuration ARM: dts: omap4-droid4: Add CPCAP PMIC battery charger configuration ARM: dts: omap4-droid4: Add CPCAP PMIC ADC configuration ARM: dts: omap4-droid4: Stop disabling SRAM and GPMC ARM: dts: omap4-droid4: Fix interrupt triggering for cpcap ARM: dts: am335x-icev2: Add CPSW ethernet0 and ethernet1 ARM: dts: am57xx-idk: Add DCAN support Signed-off-by: Olof Johansson <olof@lixom.net>
