mailbox: mtk-cmdq: Remove proprietary cmdq_task_cb

2022-08-02T20:06:57+00:00

rx_callback is a standard mailbox callback mechanism and could cover the function of proprietary cmdq_task_cb, so use the standard one instead of the proprietary one. Client driver has changed to use standard rx_callback, so remove proprietary cmdq_task_cb. Signed-off-by: Chun-Kuang Hu Reviewed-by: Matthias Brugger Signed-off-by: Jassi Brar

mailbox: mtk-cmdq: Add struct cmdq_pkt in struct cmdq_cb_data

2021-06-26T16:40:20+00:00

Current client use 'struct cmdq_pkt' as callback data, so change 'void *data' to 'struct cmdq_pkt *pkt'. Keep data until client use pkt instead of data. Signed-off-by: Chun-Kuang Hu Reviewed-by: Yongqiang Niu Signed-off-by: Jassi Brar

mailbox: mtk-cmdq: Remove cmdq_cb_status

cmdq_cb_status is an error status. Use the standard error number instead of cmdq_cb_status to prevent status duplication. Signed-off-by: Chun-Kuang Hu Reviewed-by: Yongqiang Niu Signed-off-by: Jassi Brar

mailbox: arm_mhuv2: Add driver

2020-12-10T01:26:02+00:00

This adds driver for the ARM MHUv2 (Message Handling Unit) mailbox controller. This is based on the accepted DT bindings of the controller and supports combination of both transport protocols, i.e. doorbell and data-transfer. Transmitting and receiving data through the mailbox framework is done through struct arm_mhuv2_mbox_msg. Based on the initial work done by Morten Borup Petersen from ARM.

mailbox: zynqmp-ipi-message: Replace zero-length array with flexible-array member

2020-10-29T22:22:59+00:00

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].
