serial: zynqmp: Fetch baudrate from dtb and update

2023-11-07T12:47:08Z

The baudrate configured in .config is taken by default by serial. If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial. So, the environment also needs to be updated with the dtb baudrate to avoid the glitches on the serial. Also add test to cover this new function.

configs: Add support in Kconfig and convert for armada boards

2023-11-07T12:47:08Z

Move the DEFAULT_ENV_IS_RW to Kconfig for easier configuration. Hence, add the CONFIG_DEFAULT_ENV_IS_RW config to the defconfig files to allow enabling them for armada boards.

serial: introduce CONFIG_CONSOLE_FLUSH_ON_NEWLINE

2023-10-24T21:05:24Z

When debugging, one sometimes only gets partial output lines or nothing at all from the last printf, because the uart has a largish buffer, and the code after the printf() may cause the CPU to hang before the uart IP has time to actually emit all the characters. That can be very confusing, because one doesn't then know exactly where the hang happens. Introduce a config knob allowing one to wait for the uart fifo to drain whenever a newline character is printed, roughly corresponding to the effect of setvbuf(..., _IOLBF, ...) in ordinary C programs. Since this uses IS_ENABLED() instead of cpp ifdef, we can remove the ifdef around the _serial_flush() definition - if neither CONSOLE_FLUSH_SUPPORT or CONSOLE_FLUSH_ON_NEWLINE are enabled, the compiler elides _serial_flush(), but it won't warn about it being unused.

serial: sh: Add RZ/G2L SCIF support

2023-10-19T15:03:20Z

Extend the existing driver to support the SCIF serial ports on the Renesas RZ/G2L (R9A07G044) SoC. This also requires us to ensure that if there is a reset signal defined in the device tree, it is de-asserted before we try to talk to the SCIF module.

serial: sh: Fix error handling

2023-10-19T15:03:15Z

The current SCIF error handling is broken for the RZ/G2L. After a break condition has been triggered, the current code is unable to clear the error and serial port output never resumes. The RZ/G2L datasheet says that most error conditions are cleared by resetting the relevant error bits in the FSR & LSR registers to zero. To clear framing errors on SCIF ports, the invalid data also needs to be read out of the receive FIFO. After reviewing datasheets for RZ/G2{H,M,N,E}, R-Car Gen4, R-Car Gen3 and even SH7751 SoCs, it's clear that this is the way to clear errors for all of these SoCs. While we're here, annotate the handle_error() function with a couple of comments as the reads and writes themselves don't immediately make it clear what we're doing.
