10. Display

The e-ink display pipeline end to end: the DPU/DSI hardware and boot-time EPD-PMIC bring-up, the boot splash shown on it, the userspace/kernel-driver e-ink software stack (/dev/ebc, waveform, front-light), its register-level FPGA/TCON driver internals, the Wacom EMR pen digitizer (a separate but tightly-coupled digitizer sharing the panel), and the display HAL layer. Capacitive touch is a separate digitizer and lives in Capacitive touch (Parade pt_core).
