misc: aspeed: add a raw value setting interface for uart routing

2021-07-14T17:10:33+00:00

This commit adds a raw value setting interface for uart routing to provide an atomic way of switching the route. Signed-off-by: Jae Hyun Yoo Change-Id: Id8b80f44f9a503d9f25a692211fc5ec78500ce68

Move Aspeed eSPI driver to soc/aspeed tree

2021-07-14T17:04:18+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-espi-slave: fix SUS_WARN handling logic

2021-07-14T17:04:18+00:00

This commit fixes SUS_WARN handling as dual-edge detection mode to support deepsx entry event properly. Signed-off-by: Jae Hyun Yoo

misc: aspeed: Add Aspeed UART routing control driver.

2021-07-14T16:36:10+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

2021-07-14T16:36:10+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].

platform/x86: hp_accel: Avoid invoking _INI to speed up resume

2021-06-03T07:00:39+00:00

[ Upstream commit 79d341e26ebcdbc622348aaaab6f8f89b6fdb25f ] hp_accel can take almost two seconds to resume on some HP laptops. The bottleneck is on evaluating _INI, which is only needed to run once. Resolve the issue by only invoking _INI when it's necessary. Namely, on probe and on hibernation restore.

mei: request autosuspend after sending rx flow control

2021-06-03T07:00:32+00:00

commit bbf0a94744edfeee298e4a9ab6fd694d639a5cdf upstream. A rx flow control waiting in the control queue may block autosuspend. Re-request autosuspend after flow control been sent to unblock the transition to the low power state.
