Andy, The half of what is described here are implemented in my patches. But I cannot understand the other half. Each of six AM335x UARTs has RTS/CTS pins which are controlled by pinmux in device tree, no magic required here. 2015-12-27 15:47 GMT+03:00 Andy Shevchenko : > +Peter, Russell, and Mat

GPIO-driven RTS on TI hardware with 8250_omap driver

2015-12-26 Thread Ильяс Гасанов
Hello. We are upgrading to the 4.1.x kernel for our smart metering appliance project, which is based on TI's Sitara hardware (AM335x SoC), and I decided to switch from omap-serial legacy driver to the newer 8250-based one. It marginally increases throughput efficiency, CPU cycle wise, among other
