Merge tag 'imx-fixes-4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
Pull "i.MX fixes for 4.13, round 2" from Shawn Guo: - Add missing 'ranges' property for i.MX25 device tree TSCADC node, so that it's child nodes ADC and TSC device can be probed by kernel. - Fix i.MX GPCv2 power domain driver to request regulator after power domain initialization, since regulator could defer probing and therefore cause power domain initialized twice. * tag 'imx-fixes-4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: dts: i.MX25: add ranges to tscadc soc: imx: gpcv2: fix regulator deferred probe
