We currently warn the user when tty->port is not set in tty_init_dev yet. The warning says that the kernel will crash later. And it really will only few lines below at: tty->port->itty = tty; So be nice and avoid the crash -- return an error instead. And update the warning. Signed-off-by:

The interrupt clear flag register is a "write 1 to clear" register. So, only writing ones allows to clear flags: - Replace buggy stm32_clr_bits() by a simple write to clear error flags - Replace useless read/modify/write stm32_set_bits() routine by a simple write to clear TC (transfer complete) flag.

PL011's ->flush_buffer() implementation releases and reacquires the port lock. Due to a race condition here, data can end up being added to the circular buffer but neither being discarded nor being sent out. This leads to, for example, tcdrain(2) waiting indefinitely. Process A Process B uart_flush_buffer() - acquire lock - circ_clear - pl011_flush_buffer() -- release lock -- dmaengine_terminate_all() uart_write() - acquire lock - add chars to circ buffer - start_tx() -- start DMA - release lock -- acquire lock -- turn off DMA -- release lock // Data in circ buffer but DMA is off According to the comment in the code, the releasing of the lock around dmaengine_terminate_all() is to avoid a deadlock with the DMA engine callback. However, since the time this code was written, the DMA engine API documentation seems to have been clarified to say that dmaengine_terminate_all() (in the identically implemented but differently named dmaengine_terminate_async() variant) does not wait for any running complete callback to be completed and can even be called from a complete callback. So there is no possibility of deadlock if the DMA engine driver implements this API correctly. So we should be able to just remove this release and reacquire of the lock to prevent the aforementioned race condition.

Per Documentation/DMA-API-HOWTO.txt, To unmap a scatterlist, just call: dma_unmap_sg(dev, sglist, nents, direction); .. note:: The 'nents' argument to the dma_unmap_sg call must be the _same_ one you passed into the dma_map_sg call, it should _NOT_ be the 'count' value _returned_ from the dma_map_sg call. However in the driver, priv->nent is directly assigned with value returned from dma_map_sg, and dma_unmap_sg use priv->nent for unmap, this breaks the API usage. So introduce a new entry orig_nent to remember 'nents'. Fixes: da3564ee ("pch_uart: add multi-scatter processing") Signed-off-by:

This means removing support for checking magic in amiserial.c (SERIAL_PARANOIA_CHECK option), which was checking a magic field which doesn't currently exist in the struct. That code hasn't built at least since git. Removing the definition from the header is safe anyway as that code was from another driver and not including it. Signed-off-by:

hci_qca interfaces to the wcn3990 via a uart_dm on the msm8998 mtp and Lenovo Miix 630 laptop. As part of initializing the wcn3990, hci_qca disables flow, configures the uart baudrate, and then reenables flow - at which point an event is expected to be received over the uart from the wcn3990. It is observed that this event comes after the baudrate change but before hci_qca re-enables flow. This is unexpected, and is a result of msm_reset() being broken. According to the uart_dm hardware documentation, it is recommended that automatic hardware flow control be enabled by setting RX_RDY_CTL. Auto hw flow control will manage RFR based on the configured watermark. When there is space to receive data, the hw will assert RFR. When the watermark is hit, the hw will de-assert RFR. The hardware documentation indicates that RFR can me manually managed via CR when RX_RDY_CTL is not set. SET_RFR asserts RFR, and RESET_RFR de-asserts RFR. msm_reset() is broken because after resetting the hardware, it unconditionally asserts RFR via SET_RFR. This enables flow regardless of the current configuration, and would undo a previous flow disable operation. It should instead de-assert RFR via RESET_RFR to block flow until the hardware is reconfigured. msm_serial should rely on the client to specify that flow should be enabled, either via mctrl() or the termios structure, and only assert RFR in response to those triggers.

Currently flow control is not working due to lpuart32_set_mctrl that is clearing TXCTSE bit in all cases. This bit gets earlier setup by lpuart32_set_termios. As I read in Documentation set_mctrl is also not meant for hardware flow control rather than gpio setting and clearing a RTS signal. Therefore I guess it is safe to remove the whole code in lpuart32_set_mctrl. This was tested with console on a i.MX8QXP SoC. Signed-off-by:
