[PATCH] ARM: dts: i.MX25: add ranges to tscadc

From: Martin Kaiser
Date: Wed Aug 02 2017 - 16:07:17 EST


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.
