Bring-up of the Moto Edge 40 Pro (rtwo) on the SM8550 kernel: - dts: NT37705 DSI panel with DSC, Goodix GT9916P touch, ADSP/CDSP with pmic-glink (battery, UCSI), Adreno 740, WiFi (WCN7850/ath12k), physical keys, and USB-C DisplayPort (pmic-glink altmode -> PS5169 redriver -> FSA4480 -> QMP combo PHY -> mdss_dp0) following the sm8550-qrd layout. - DP link capped at HBR (link-frequencies on &mdss_dp0_out): the DP->HDMI converter of a common USB-C hub trains fine at HBR2 but its HDMI output flickers and drops HPD; HBR x2 still covers 1080p60. - new drivers: typec-mux-ps5169.c (Parade PS5169 redriver as typec switch/retimer), panel-novatek-nt37705.c. - patches: msm DP invalid LTTPR caps + no push_idle with the link down (hardware reset on unplug), msm DSI keeps the panel DSC config, ath12k regd fixes and MHI keep-awake, ICC keepalive for the MDP fetch path. - rtwo.config / config-motorola-rtwo.aarch64: options for all of the above.
