Changes

In order to simplify implementation of host board power supply unit, Lizard DLxxxxxx1 part number family has been made available. DLxxxxxx1 modules have just one requirement to comply with, and it is related to the touch controller. The following diagram shows the power up sequence requirements that must be respected in order to make sure that the TSC2003 is reset to a default working state after every power up. During the power up process, the I2C bus must be in an idle state, that is the SCL and SDA pins must be high before the power supply pin (+Vcc) ramps up to 0.9 V). The Vhigh value is 2V.
