[PATCH v3 0/2] Ambarella CV75: 8250_dw UART
From: Long Zhao via B4 Relay
Date: Thu Aug 13 2026 - 06:35:28 EST
This is part C of a 3-part CV75 v3 split:
A: bindings + RCT/CCU clocks + SoC/EVK DT + MAINTAINERS
B: pinctrl + PL061 GPIO variant
C: 8250_dw UART quirks (this series)
Depends on series A:
https://lore.kernel.org/r/20260813-cv75-v3-a-v3-0-cfdd20b1b4dd@xxxxxxxxxxxxx
Depends on series B:
https://lore.kernel.org/r/20260813-cv75-v3-b-v3-0-1d82e18da09b@xxxxxxxxxxxxx
Link to v2:
https://lore.kernel.org/r/20260806-longzhao-upstream-cv75-v2-v2-0-6b09707c5fe9@xxxxxxxxxxxxx
Summary:
- document ambarella,cv75-uart on snps,dw-apb-uart
- Ambarella quirks in 8250_dw
Changes since v2 (C scope):
- drop custom Ambarella UART driver; reuse 8250_dw (Linus)
Verified on CV75 with A+B+C.
