      Move MIPI DSI & CSI sheets into a "MIPI" sheet, both DSI and CSI will likely use the I2C level shifter

      Begin assigning footprints to passive components, add component information to the common 10k resistors throughout the schematic, include TVS diodes on the switch/button I/O pins, use the DB2J20900L schottky diode throughout the design (in place of the ZLLS400)
      
      Added notes about the battery holder, battery size, and the fact that the 103HT thermistor can fit underneath the 18650 battery when the battery is insterted into the holder.
      
      Included frequency response curve for the new/cheaper SMD speaker (slightly thicker mechanical dimension).
      
      Included note about the RedPine RS9116's SDIO_RESET# line expecting a 2.31V VIH logic level, increased the pull-up to 100k (M.2 standard states that this is should be 1.8V level).
      
      Added a TODO note stating the 1.8V logic-level I2C devices should share the same level-shifter that will be on the top-level circuit (in next commit).

      Flip the direction of FULL_CARD_POWER_OFF# and W_DISABLE*# switches such that the devices are on when the switch is open, this should ever so slightly reduce the power consumption when these devices are used (most likely more often than them being off)

      Add current sense resistors and jumper symbols in the schematic, assign the various signals left unspecified, complete the PWR_EN assignment and verify that thepower sequence would be brought up in the correct order, add an LED to the VBAT_REG rail for debugging purposes (know when the board is receiving power)
      
      Both the GP_LED1 and the HAPTIC motor are able to be controlled via PWM2 by individually MUXing the corresponding pads to PWM2. Only one pin should be MUXed to PWM2 at a time whilst the other is a GPIO, otherwise they will behave identically.
      
      The I2C buses do not need the bus switch found on the EmCraft baseboard since the M.2 modules' power is controlled by PWR_EN and their I2C is level shifted between 1.8V<->3.3V, making it safe to leave them as is.
      
      The various sense resistors have their corresponding parts selected but will be "NC" in the BoM and will not be assembled during manufacturing. To measure the current on the various rails (and WLAN M.2), one will need to break the trace between the two pads and place the corresponding resistor. A jumper (1.27 or 2.45 still needs to be determined) can be used to re-short these pads.
      
      Notes have been added regarding which GPIO pins can easily be interchanged if it improves the layout.
      
      Selected a better/cheaper RJ45 receptacle. Also picked out a well-suited green LED to be used in various spots throughout the board.
