From: Vincent Mailhol Date: Fri, 10 Jun 2022 14:30:06 +0000 (+0900) Subject: can: Kconfig: add CONFIG_CAN_RX_OFFLOAD X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bfe0092dc237963b035d8404ecd61d60f0ef1a5d;p=linux.git can: Kconfig: add CONFIG_CAN_RX_OFFLOAD Only a few drivers rely on the CAN rx offload framework (as of the writing of this patch, only four: flexcan, m_can, mcp251xfd and ti_hecc). Split it out of can-dev and add a new config symbol: CAN_RX_OFFLOAD. The drivers relying on CAN rx offload are in different sub folders. Make CAN_RX_OFFLOAD an hidden option and tag all the drivers depending on that feature with "select CAN_RX_OFFLOAD" so that the option gets automatically enabled if and only if one of those drivers is chosen.
