Subject: ARM: at91: Add ADC driver to at91sam9260/at91sam9g20 dtsi files
X-Git-Tag: v3.5-rc1~154^2^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=73d68d91aa1b9e9cb6c1635143799c0fec484c08;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

ARM: at91: Add ADC driver to at91sam9260/at91sam9g20 dtsi files

Now that the bulk of at91sam9g20-related nodes are located in at91sam9260.dtsi,
we have to re-create the path to this ADC node for SoC specific parts.
