kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig.

serial: introduce SERIAL_SUPPORT_INTERRUPT Kconfig option As not all drivers support interrupts we don't have a means to know if we can allow UART_INTERRUPT_DRIVEN to be enabled and thus various Kconfig options that select UART_INTERRUPT_DRIVEN. Some drivers have a interrupts, however not all do. So introduce a Kconfig option to let us know what the driver actually supports. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

int "Port 1 TX Interrupt Threshold Count"
uart: sifive: align txcnt of UART1 with UART0 The UART1 is not actually accessible on the HiFive1 since the QFN48 package for the FE310, used by this board, does not expose the required pads. However, it is still possible to use the UART1 on HiFive1 emulators (e.g. using UART0 for debugging and UART1 for SLIP). Unfortunately, the UART0 and UART1 currently have different default configurations when it comes to the configured transmission watermark (txcnt). With a txcnt of zero (the default for UART1) the UART is not actually usable (see #18118). Contrary to UART0 (see #23699), the UART1 does therefore not work by default on Zephyr which took me some time to figure out. This commit aligns the default UART1 configuration with the UART0, thereby making it work by default. Signed-off-by: Sören Tempel <tempel@uni-bremen.de>
