Move Aspeed eSPI driver to soc/aspeed tree

2021-08-02T16:04:00+00:00

This commit moves Aspeed eSPI driver from misc to soc/aspeed tree to make correct probing order for LPC and eSPI driver. Since LPC runs over eSPI, eSPI driver should be registered ahead of LPC driver. Signed-off-by: Jae Hyun Yoo

misc: aspeed: Add Aspeed UART routing control driver.

2021-08-02T16:04:00+00:00

This driver adds sysfs files that allow the BMC userspace to configure how UARTs and physical serial I/O ports are routed. Tested: Checked correct behavior (both read & write) on TYAN S7106 board by manually changing routing settings and confirming that bits flow as expected. Tested for UART1 and UART3 as this board doesn't have the other UARTs wired up in a testable way.

Add AST2500 eSPI driver

2021-08-02T16:04:00+00:00

When PCH works under eSPI mode, the PMC (Power Management Controller) in PCH is waiting for SUS_ACK from BMC after it alerts SUS_WARN. It is in dead loop if no SUS_ACK assert. This is the basic requirement for the BMC works as eSPI slave. Also for the host power on / off actions, from BMC side, the following VW (Virtual Wire) messages are done in firmware: 1. SLAVE_BOOT_LOAD_DONE / SLAVE_BOOT_LOAD_STATUS 2. SUS_ACK 3. OOB_RESET_ACK 4. HOST_RESET_ACK Also, it provides monitoring interface of PLTRST_N signal through /dev/espi-pltrstn Signed-off-by: Haiyue Wang Signed-off-by: Jae Hyun Yoo Signed-off-by: James Feist Signed-off-by: Vernon Mauery

misc: Remove obsolete mctp-lpc chardev

2021-06-24T09:23:28+00:00

The mctp-lpc chardev is replaced (temporarily) by the raw KCS chardev. The raw chardev is required for IBM's purposes until Jeremy's socket-based MCTP patches are merged[1][2].

misc: Add ASPEED KCS driver for MCTP purposes

2021-02-09T01:06:08+00:00

IBM have developed a vendor-defined MCTP binding that utilises LPC IO and FW interfaces to exchange MCTP messages. A KCS device in the IO space is used to send single-byte control messages initialising the MCTP channel and exchanging ownership of data buffers. This driver exposes the KCS message stream to userspace, allowing an MCTP-capable application to manipulate the data exposed via the FW space.

misc: mic: remove the MIC drivers

2020-10-28T18:12:03+00:00

This patch removes the MIC drivers from the kernel tree since the corresponding devices have been discontinued. Removing the dma and char-misc changes in one patch and merging via the char-misc tree is best to avoid any potential build breakage.

misc: hisi_hikey_usb: Driver to support onboard USB gpio hub on Hikey960

2020-09-10T16:56:38+00:00

The HiKey960 has a fairly complex USB configuration due to it needing to support a USB-C port for host/device mode and multiple USB-A ports in host mode, all using a single USB controller. See schematics here: https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf This driver acts as a usb-role-switch intermediary, intercepting the role switch notifications from the tcpm code, and passing them on to the dwc3 core. In doing so, it also controls the onboard hub and power gpios in order to properly route the data lines between the USB-C port and the onboard hub to the USB-A ports.
