From: Long Zhao <redacted> The Ambarella CV75 UART is Ambarella IP, not a Synopsys DesignWare licensed block. At the register level it is close enough to DW APB UART that a full custom UART driver is unnecessary: reuse 8250_dw with a small platform quirk. Quirks: - keep IER ETOI (bit 5) set for RX timeout behaviour - skip set_rate; baud clock is managed outside the UART block Signed-off-by: Long Zhao <redacted>
This is really nice. Compare the size of this to what was initially submitted! Reviewed-by: Linus Walleij <linusw@kernel.org> Yours, Linus Walleij
