Subject: ARM: dts: rockchip: enable the tsadc for rk3228 evb
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=26f5e19dfb07de627112074721f254482f941dab;p=linux-beck.git

ARM: dts: rockchip: enable the tsadc for rk3228 evb

This patch enables the tsadc for rk3228 evb board.

The rk3228 evb board uses the CRU to reset the chip since it hasn't the
PMIC to connect it, and TSHUT is low active on evb board.
