      OMAP: add RS485 support · 4a0ac0f5
      Mark Jackson authored
      This patch adds RS485 support to the OMAP serial driver, as
      defined in:-
      
      Documentation/devicetree/bindings/serial/rs485.txt
      
      When a UART transmitter is connected to (eg) a RS485 driver, it is
      necessary to turn the driver on/off as quickly as possible.  This is
      best achieved in the serial driver itself (rather than in userspace
      where the latency can be quite large).
      
      This patch allows a GPIO pin to be defined (via DT) that controls
      the enabling of the driver at the start of a message, and disables
      the driver when the message has been completed.
      
      When RS485 is disabled, the RTS pin is set to on.

      tty: ar933x_uart: simplify use of devm_ioremap_resource · 071eb0ff
      Julia Lawall authored
      Remove unneeded error handling on the result of a call to
      platform_get_resource when the value is passed to devm_ioremap_resource.
      
      Move the call to platform_get_resource adjacent to the call to
      devm_ioremap_resource to make the connection between them more clear.
      
      A simplified version of the semantic patch that makes this change is as
      follows: (http://coccinelle.lip6.fr/)
      
      // <smpl>
      @@
      expression pdev,res,n,e,e1;
      expression ret != 0;
      identifier l;
      @@
      
      - res = platform_get_resource(pdev, IORESOURCE_MEM, n);
        ... when != res
      - if (res == NULL) { ... \(goto l;\|return ret;\) }
        ... when != res
      + res = platform_get_resource(pdev, IORESOURCE_MEM, n);
        e = devm_ioremap_resource(e1, res);
