AM3358: UART 8250 driver

Sh.Sasaki

Part Number: AM3358

Hi all,

I confirmed the following thread.

e2e.ti.com/.../527378

So I have two question.

  1. What is the difference between omap-serial and 8250 driver? Is it the only difference between using GPIO pin or RTS pin?
  2. Can the 8250 driver be controlled with GPIO instead of RTS

Best regards,

Sasaki

    Hi Sasaki-San,

    1. The omap-serial driver is made separate from 8250 driver as we cannot over load 8250 driver with omap platform specific configuration for features like DMA, it makes easier to implement features like DMA and hardware flow control and software flow control configuration with this driver as required for the omap-platform.
    2. Probably you can make a custom decision to manage a GPIO instead of RTS but this is related with schematics and source code changes.
