i3c: mctp: Add GETMWL/SETMWL and GETMRL/SETMRL support

2022-06-10T07:22:16+00:00

We need to set MRL/MWL to 69: 64 byte MCTP payload + 4 byte MCTP header + 1 byte PEC as per MCTP o. I3C spec paragraph 5.4.2. We also need to verify whether MCTP packet size meets the requirement and throw the error otherwise. Signed-off-by: Oleksandr Shulzhenko

i3c: device: Add SETMWL/GETMWL and SETMRL/GETMRL support

2022-06-10T07:22:16+00:00

Add the GETMRL/SETMRL and GETMWL/SETMWL CCC commands functions. The functions are needed to configure maximum read/write length for the specific I3C device. Signed-off-by: Oleksandr Shulzhenko

soc: aspeed: mctp: Add IOCTL to set own EID

2022-06-09T17:57:41+00:00

The driver doesn't implement MCTP logic, which means that it requires its clients to prepare valid MCTP over PCIe packets. Because we support MCTP stacks in both kernel and userspace, and since MCTP protocol is a part of userspace, we need userspace to update own EID information in kernel to provide it for in-kernel aspeed-mctp clients. Previously, own EID information was updated by userspace using SET_EID_INFO which now is deprecated and replaced by SET_EID_EXT_INFO to pass CPU EID and Domain ID mappings. To provide own EID information for in-kernel clients, add a dedicated IOCTL. Signed-off-by: Iwona Winiarska

soc: aspeed: mctp: Mark GET_EID_INFO/SET_EID_INFO as deprecated

2022-06-09T17:57:41+00:00

ASPEED_MCTP_GET_EID_INFO and ASPEED_MCTP_SET_EID_INFO shouldn't be used in future projects - they are replaced by EXT_INFO variants. Update documentation for aspeed-mctp UAPI header to mark them as deprecated. Signed-off-by: Iwona Winiarska

peci: busses: add PECI o. MCTP o. I3C platform driver

2022-06-01T08:46:09+00:00

Add PECI adapter that allows to send MCTP PCI VDM packets via i3c-mctp driver. Signed-off-by: Oleksandr Shulzhenko

i3c: mctp: Add PECI-related functionality to I3C MCTP driver

2022-06-01T08:46:09+00:00

- Handler for PECI messages have been added; - i3c_mctp_client and platform_device for PECI have been added. Signed-off-by: Oleksandr Shulzhenko

i3c: mctp: Extend MCTP o. I3C driver with the TX/RX functions

2022-06-01T08:46:09+00:00

Extend the driver with the functionality necessary to send and receive MCTP over I3C packets by another component in kernel: - i3c_mctp_client concept needed to implement packet queue so that the driver can manage and classify packets for several clients respectively; - the function that provides MCTP target EID; - the functions to alloc and free mctp_i3c_packet; - the functions to send and receive MCTP packets over I3C.

Revert "i3c: mctp: Replace redundant MKDEV calls"

2022-05-27T13:21:19+00:00

This reverts commit 825fd72c22d729a4ad0d4d3ee488525710fe9877. Minor was passed as one of the arguments - it was not redundant and removing it introduces a regression. Signed-off-by: Iwona Winiarska
