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. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

# MCP2515 CAN configuration options
drivers: can: mcp2515: Add driver for MCP2515 CAN controller The MCP2515 is a CAN controller that can be connected via SPI to an host MCU. This driver adds support for the MCP2515 as a new driver in the CAN subsystem. As it is a SPI peripheral it uses a thread for its interrupt handling and the received message filtering is done inside this interrupt thread, as the MCP2515 filter capabilities are not sufficient for the Zephyr CAN interface. The driver was validated with an external CAN logger and the adjusted CAN sample application. Signed-off-by: Karsten Koenig <karsten.koenig.030@gmail.com>

drivers: can: Extend CAN API for bus-state management. This commit extends the CAN API with the following functions: - can_get_state - can_recover - can_register_state_change_isr This functions can be used to get the error-counters and the state of the CAN controller. The recover function can be used to recover from bus-off state when automatic recovery is disabled. Signed-off-by: Alexander Wachter <alexander.wachter@student.tugraz.at>
