Add decoupling capacitors near the WLAN+BT M.2 Key E socket, assign the tantalum capacitors their various footprints, find suitable 220uF tantalum bulk capacitors for the M.2 modules which are rated to 10V

Need to figure out if the load switch IC (AP22800) that derives 3V3_P is fine with having the large output capacitance (no unwanted reverse current).

Make corrections to schematic based on Emcraft's baseboard revision changes

Assign most of the capacitors their respective footprints (most are 0603s), add camera/CSI connector component info, source cheaper distributors for 3.5mm headset jack and RJ45

Add notes regarding I2C's 3V3_OUT supply and the fact that it is sourced from NVCC_3P3 (3A BUCK6), add additional notes regarding the RTC and Camera's I2C slave address, reannotate the whole schematic (nearly the last time)

Add WWAN and WLAN+BT MHF4 coax connectors and antennae symbols to the schematic, remove home and back buttons, reorder sheets so that GNSS is above the haptic motor sheet

Begin GNSS schematic using MAX-M8 module

Since UART2 isn't brought out then will either need to use UART1 (debug) with jumpers or the module's I2C interface.

Resolve merge conflict after pulling recent commit, now can no longer use SSH (since Gogs is getting abandoned?).

Add camera/CSI circuit, include second switch that is part of the audio+camera DPDT for killing both simultaneously, level shifters used for camera's I/O that requires it, footprints for a 1.8V LDO which may be used by DVDD will be included

External DVDD (1.8V LDO) needs to be tested if it's needed (datasheet says an internal DVDD can be used, as is the case with Boundary Devices' OV5640 camera).

Add bypass caps to logic gates used with the W_DISABLE and the 9-axis IMU's INT pins

Nearly complete the LCD/DSI and cap-touch schematic, add notes from the display's datasheet regarding the various pin assignments, add component property information for the 39-pin DSI clamshell connector

Still need to determine what this requested "low power state signal" requirement is for the display.

Add LCD display's 22.4V (@40mA) LED backlight driver/boost converter IC circuit (PAM2841), selected the rectifying/schottky diode (SS14), and set the OVP to 37.6V as found on the IC's EVB
