Remove Glamo (U1801)
+Changes:
+- Removed Glamo (U1801) and related passives
+- LCM pixel data reassigned directly to screen
+- LCM controller SPI moved to GPIO (GPG-5-7)
+- LCD_xRES signal moved to GPD9
+- LP Filters for LCM interface rearranged for better organization
To do:
-- components to remove
-- reassign LCM pixel data (check voltage domain !)
-- reassign LCM controller SPI (check voltage domain !)
- reassign SD/MMC
- move WLAN to SPI
- software impact of LCM pixel change on kernel

Items to add:
- NC pullup resistor to second interrupt (INT2) of remaining sensor
+Changes:
+- Moved CS signal of remaining sensor to GPG0
+- Connected INT2 of remaining sensor to GPG8 (formerly INT1 of other sensor)

To do:
- why the upper ?
- connect both interrupts (motivation)

-- simplification of supply voltage circuit
-- readjust antenna-side components of RF filter
+Changes to implement in order to remove the external GPS antenna:
+
+- Remove U7606 and C7620
+- Merge C7601 and C7630 into a single capacitor, or remove them completely
+- Remove U7605, R7620, C7623, R7613, R7614, C7629, C7628 (external
+ antenna power sense)
+- Remove R7615, Q7602 and R7617. Connect R7610 to LNA_AVDD.
