If a port has no dma channel defined in the device tree, then don't attempt to allocate a dma channel for the port. Also suppress the warning message concerning the failure to allocate a dma channel.

The atmel serial port driver reported the following warning on suspend: atmel_usart f8020000.serial: ttyS1: Unable to drain transmitter As the ATMEL_US_TXEMPTY status bit in ATMEL_US_CSR is always cleared when the transmitter is disabled, we need to know the transmitter's state to return the real fifo state. And as ATMEL_US_CR is write-only, it is necessary to save the state of the transmitter in a local variable, and update the variable when TXEN and TXDIS is written in ATMEL_US_CR. After those changes, atmel_tx_empty can return "empty" on suspend, the warning in uart_suspend_port disappears, and suspending is 20ms shorter for each enabled Atmel serial port.

The imx serial driver uses PAGE_SIZE when allocating rx_buf, but then uses RX_BUF_SIZE (which is currently defined as PAGE_SIZE) to describe the length of the buffer when initialising the scatter gather list. In order to ensure that this stays consistent, use RX_BUF_SIZE in both locations.

The variable dma_is_rxing is currently set to 1 in imx_disable_rx_int(). This is problematic as: - whilst imx_disable_rx_int() is currently always called before start_rx_dma() this dependency isn't obvious. - start_rx_dma() does error checking and might exit without enabling DMA. Currently this will result in dma_is_rxing suggesting that DMA is being used for recieving. To avoid these issues, move the setting of dma_is_rxing to start_rx_dma() when appropriate.

UART core function uart_update_mctrl relies on a cached value of modem control lines. This was used but not updated by local RTS control functions within imx.c. These are used for RS485 line driver enable signalling. Having an out-of-date value in the cached mctrl can result in the transmitter being enabled when it shouldn't be. Fix this by updating the mctrl value before applying it.

As a side effect this adds support for parsing rs485-rts-delay and rs485-rx-during-tx. As the driver doesn't support this though, probing fails if these are defined.

We just got a common helper for parsing the rs485 specific device tree properties. Use it and drop the open coded parser. Note that there is a small difference between the removed and the now used implementation: The former cleared flags to 0 if rs485-rts-delay was given, the common helper clears SER_RS485_RX_DURING_TX and SER_RS485_ENABLED only but always which makes more sense.

Since commit a6d7514b ("tty: serial: lpuart: add a more accurate baud rate calculation method") the baud rate is now calculated inside the lpuart32_serial_setbrg() function, so we no longer need to read the UARTBAUD register inside lpuart32_set_termios(). The 'bd' variable can be simply removed. This fixes the following build warning with W=1: drivers/tty/serial/fsl_lpuart.c: In function 'lpuart32_set_termios': drivers/tty/serial/fsl_lpuart.c:1652:32: warning: variable 'bd' set but not used [-Wunused-but-set-variable] Fixes: a6d7514b ("tty: serial: lpuart: add a more accurate baud rate calculation method") Signed-off-by: NFabio Estevam <fabio.estevam@nxp.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>
