fixup! peci: Add support for PECI bus driver core

2021-03-10T20:14:54+00:00

Per recommendation from the CPU team, reduce the first retry delay to 100us. Use usleep instead of schedule_timeout to avoid stretching the delay. Change-Id: I6698b0f05f952aaef737dd09280a17aaec81a2c5 Signed-off-by: Jason M. Bills

ASD Prevent TDI remaining bits to be override during JTAG xfer

2021-03-09T22:20:41+00:00

JTAG xfer length is measured in bits and it is allowed to send non 8-bit aligned xfers. For such xfers we will read the content of the remaining bits in the last byte of tdi buffer and restore those bits along with the xfer readback. Add also linux types to JTAG header to remove external dependencies. Test: SPR ASD Sanity and jtag_test finished successfully. SKX ASD Sanity and jtag_test finished successfully.

soc: aspeed: mctp: Export function used to read BDF

2021-02-04T13:16:07+00:00

Recently, aspeed-mctp driver functionality was extended to store BDF values for already discovered MCTP endpoints on PCIe bus. Let's expose kernel API to read BDF based on endpoint ID. Change-Id: I146e67a8c2f4f541b4c3065c18dcadf531f30670 Signed-off-by: Iwona Winiarska

Fix reset index of LPC and eSPI

2021-01-13T20:21:36+00:00

AST2600 A1 has separate reset control for LPC and eSPI so this commit fix the index definition to make it work on AST2600 A1. Change-Id: Ied8f96740b6df802a65313fde369e79386557903 Signed-off-by: Jae Hyun Yoo

Update I3C drivers

2021-01-08T02:22:52+00:00

This commit ports I3C updates from Aspeed SDK v00.06.00. Note: Should be refined to get upstreamed. Signed-off-by: Dylan Hung Change-Id: Ic674bf5d6b5e72b389c739b136710915aabc6324

fixup! soc: aspeed: mctp: Expose internal kernel API

2021-01-07T01:18:44+00:00

Fixed a missing error handling for case where wait_event_interruptible_timeout() returns -ERESTARTSYS. Renamed the exposed functions to be more consistent with their usage. Added dedicated function to flush client rx queue. Change-Id: I0fd1bfca926b34ae0f4dc18f07e453b3861a4c3e Signed-off-by: Iwona Winiarska

peci: Add peci_revision property

2020-12-17T09:19:12+00:00

Right now, PECI revision is determined using a result of GetDIB() PECI command. Because GetDIB() may not be supported by all type of physical media that provides PECI, we need an alternative. Until we figure how to determine PECI revision there (if we can't do that, we'll fallback to device tree), let's allow to hardcode PECI revision as a property of hardware adapter.

soc: aspeed: mctp: Expose internal kernel API

2020-12-17T09:19:12+00:00

Some protocols that are already implemented in kernel can be encapsulated in MCTP packets. To allow use aspeed-mctp internally in kernel space, let's allow to use selected functions outside of aspeed-mctp. Change-Id: I543bfce975dfdd7cf8017899a139f69febbaca8d Signed-off-by: Iwona Winiarska

aspeed-mctp: Add EID information related ioctls

2020-12-16T09:36:59+00:00

Implement two new ioctls for storing EID related information: * ASPEED_MCTP_IOCTL_GET_EID_INFO * ASPEED_MCTP_IOCTL_SET_EID_INFO Driver stores EID mapping in a list which is traversed when one tries to get information using ASPEED_MCTP_IOCTL_GET_EID_INFO ioctl, when given EID mapping is not found in the list, next entry is returned. When there are no entries with EIDs higher than specified in the IOCTL call -ENODEV is returned. Whenever new information about EID mapping is stored with ASPEED_MCTP_IOCTL_SET_EID_INFO ioctl driver empties exsiting list of mappings and creates new one based on user input. After insertion list is sorted by EID. Invalid input such as duplicated EIDs will cause driver to return -EINVAL. Change-Id: I41e4e4e83f451a8367d58bbf9b67e8e8f7d080f4 Signed-off-by: Karol Wachowski

soc: aspeed: mctp: Add API to register client for MCTP type

2020-12-08T18:04:06+00:00

MCTP client can register for receiving packets with selected MCTP message type or PCIE vendor defined message type. Vendor defined type is 2 bytes but in Intel VDMs the first byte is variable and only the second byte contains constant message type - to support this use case we have to specify 2 byte mask that is applied to packet type before comparing with registered vendor type. When MCTP packet arrives its header is compared with a list of registered (vendor) types. If no client registered for packet's (vendor) type then the packet is dispatched to the default client. Fragmented packets are not considered for type matching. Only one client can register for given (vendor) type. Client can register for multiple (vendor) types. All packet fields must be specified in big endian byte order. This feature allows to support multiple clients simultaneously but only one client per (vendor) message type. For example we can have PECI client in kernel that uses PECI vendor message type, dcpmm daemon in user space that handles NVDIMM vendor type messages and mctpd service that handles MCTP control and PLDM message types. tested with peci_mctp_test application Change-Id: I8a9fed3d4b2f2628782299928abd15bdd7af9387 Signed-off-by: Andrzej Kacprowski
