Subject: [PATCH] ARM: dts: i.MX25: add ranges to tscadc
Date: Wed,  2 Aug 2017 22:06:11 +0200	[thread overview]
Message-ID: <1501704371-28151-1-git-send-email-martin@kaiser.cx> (raw)

Add a ranges; line to the tscadc node. This creates a 1:1 mapping between
the addresses used by tscadc and those in its child nodes (adc, tsc).

Without such a mapping, the reg = ... lines in the tsc and adc nodes do
not create a resource. Probing the fsl-imx25-tcq and fsl-imx25-tsadc
drivers will then fail since there's no IORESOURCE_MEM.
