ARM: dts: i.MX53: move common QSB nodes to new file There are (atleast) two versions of the i.MX53 LOCO: - the MCIMX53-START board - the MCIMX53-START-R board The MCIMX53-START-R has a mc34708 pmic and is otherwise the similar to the MCIMX53-START. To prepare for the START-R, move all common nodes to a new imx53-qsb-common.dtsi and remove everything but the board name and pmic from the imx53-qsb.dts.

ARM: dts: imx53-qsb: Constrain the TVE DAC voltage Quoting Philipp Zabel: "Since this regulator is used as the TVDAC analog power supply, this range should at least be limited to the analog power supply range of the TVDAC, listed in Table 74-9. of the i.MX53 reference manual (2.5-2.75V). But since the nominal voltage is 2.75V, which was used to determine the analog gain that is supposed to result in the necessary 0.7V peak-to-peak amplitude on the VGA output, I'd say we should just fix the voltage to 2750000 here." , so limit the TVDAC analog power supply as suggested.

ARM: dts: imx53-qsb: Provide the TVE DAC regulators On imx53-qsb the TVE DAC regulator comes from: - LDO7 on the board with the Dialog DA9052 PMIC - VDAC on the board with the MC34708 PMIC Pass them in the 'dac-supply' node. While at it, remove the 'regulator-always-on/regulator-boot-on' properties as the TVE driver will properly handle it. Tested on a imx53-qsb board with a Dialog DA9052 PMIC.
