[PATCH] serial/lpuart: Do not enable UART FIFO

Using FIFO in LPUART results in subtle serial input draining issues which are quite difficult to reproduce and troubleshoot. Since the change offered only moderate performance gain revert the code to operate in no-FIFO mode to avoid FIFO-related problems alltogether. Signed-off-by: Andrey Smirnov

[PATCH] gitignore: Add *.pblx files

Looks like *.pblx was accidentally dropped from ignored files list and now my "git status" is clobbered by every *.pblx image that is being built (that's quite a lot for imx_v7_defconfig). Re-add original rule to prevent that. Fixes eed8a41c5 ("gitignore: ignore pblx.simximg files") Cc: Steffen T

[PATCH v2 4/5] serial: Drop .remove functions from all drivers

Depending on specifics, some 'serdev' devices might need prevent parent console device from being removed and corresponding memory deallocated to properly function until the very end of Barebox's execution. An example of such a use-case would be a reset handler relying on a serdev device for transp

[PATCH v2 3/5] serdev: Add trivial blocking read function

[PATCH v2 5/5] serdev: Allow polling interval to be adjusted at runtime

Due to blocking, synchronous, polling driven nature of Barebox's serial communication handling trying to use two or more serial ports at high (1Mbaud+) baudrates results in data loss and noticeable perofmance degradation. This happens as soon as individual message being sent around start exceeding

[PATCH v2 2/5] console: Add simplified 'serdev' framework from Linux kernel

[PATCH v2 1/5] console: Introduce console_drain()

Generalize high baud rate UART polling code found in lib/xmodem.c and expose it as a generic function in console API. The usecase for this -- besides X/Y-mode data transfers where the code originated -- is command/reply type of serial exchages at high baud rates (~1Mbaud) with payloads exceeding i

[PATCH v2 0/5] Linux's serdev framwork port

Hi everyone: In an effort to bring this kernel driver https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/mfd/rave-sp.c?h=v4.16-rc7 to Barebox, I ended up creating a miniature and extremely simplified version of 'serdev' subsystem which is presented in this patchset. C
