[PATCH] serial: Add missing call to init UCC UART port timeout

From: Chuck Meade The UCC UART driver is missing a call to uart_update_timeout(). Without this call, attempting to close the port after outputting large amounts of data (i.e. using tty and uart buffering) results in long timeouts before the port will actually be shut down. For example, cat a

Re: UCC UART

icrocode patch requires them to be set to different rates (I believe Rx is 16*baud under soft UART mode, and Tx is 1*baud). Also, I don't know if it matters or not, but you should change your dts entry "ser...@4000" to "ser...@2200", just like you recently changed your "reg =" to 0x2200.

Re: UCC UART

to operate in Soft UART mode. I hardcoded mine because I had to backport this UCC UART driver to an older Linux kernel, and that kernel was from before dts existed. Add whatever you need to your dts to make it run in soft UART mode and get the firmware loaded.

Re: UCC UART

g between that tx pin and your display (e.g. level translation issue, null modem issue, baud incompatibility, terminal program set for XON/XOFF or HW flow control and UART not set up compatibly). For now get the probe directly on the CPU's UCC3 Tx pin, output chars and see if there is any act

Re: UCC UART

urned. That must be correct for your hardware -- must be the actual brg freq. I assume that you are booting from U-Boot. I believe in modern implementations that U-Boot fills in the brg-frequency in the device tree at boot time.

Re: Continuing UCC UART woes

reescale and try to find out what the Soft UART mode microcode patch capabilities are, in terms of exactly how many simultaneous UCC UARTs it has been proven to support. The QE has processing limits, and maybe the soft UART microcode patch can't support multiple UCC UARTs(?) It's worth it to
