2024-07-01platform/chrome: Update binary interface for EC-based charge controlThomas Weißschuh
The charge-control command v2/v3 is more featureful than v1, it additionally supports charge thresholds.

2023-09-27media: cros-ec-cec: Get number of CEC ports from ECReka Norman
Add a new CEC port count host command and use it to query the number of CEC ports from the EC. If the host command is not supported then it must be old EC firmware which only supports one port, so fall back to assuming one port. This patch completes support for multiple ports in cros-ec-cec.

2023-09-27media: cros-ec-cec: Support receiving messages from multiple portsReka Norman
Currently, received messages are sent from the EC in the cec_message MKBP event. Since the size of ec_response_get_next_data_v1 is 16 bytes, which is also the maximum size of a CEC message, there is no space to add a port parameter. Increasing the size of ec_response_get_next_data_v1 is an option, but this would increase EC-kernel traffic for all MKBP event types. Instead, use an event to notify that data is ready, and add a new read command to read the data. For backwards compatibility with old EC firmware, continue to handle cec_message events as well.

2023-09-27media: cros-ec-cec: Support multiple ports in write commandReka Norman
Add a v1 of the CEC write command which contains a port parameter. Check which versions of the write command the EC supports and use the highest supported version. If it only supports v0, check that there is only one port. With v0, the EC will assume all write commands are for port 0.

2023-09-27media: cros-ec-cec: Support multiple ports in set/get host commandsReka Norman
Reuse the top four bits of the cmd field to specify the port number. The reason for doing this as opposed to adding a separate uint8_t field is it avoids the need to add new versions of these commands. The change is backwards compatible since these bits were previously always zero, so the default behaviour is to always operate on port 0.

2023-09-27media: cros-ec-cec: Manage an array of portsReka Norman
To support multiple CEC ports, change cros_ec_cec to contain an array of ports, each with their own CEC adapter, etc. For now, only create a single port and use that port everywhere, so there is no functional change. Support for multiple ports will be added in the following patches. Signed-off-by: Reka Norman <rekanorman@chromium.org> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2023-04-24platform/chrome: Replace fake flexible arrays with flexible-array memberGustavo A. R. Silva
Zero-length arrays as fake flexible arrays are deprecated and we are moving towards adopting C99 flexible-array members instead. Use the DECLARE_FLEX_ARRAY() helper macro to transform zero-length arrays in unions with flexible-array members. Address the following warning found with GCC-13 and -fstrict-flex-arrays=3 enabled: drivers/iio/accel/cros_ec_accel_legacy.c:66:46: warning: array subscript <unknown> is outside array bounds of ‘struct ec_response_motion_sensor_data[0]’ [-Warray-bounds=] This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

2022-05-03platform/chrome: cros_ec_lpcs: reserve the MEC LPC I/O ports firstDustin L. Howett
Some ChromeOS EC devices (such as the Framework Laptop) only map I/O ports 0x800-0x807. Making the larger reservation required by the non-MEC LPC (the 0xFF ports for the memory map, and the 0xFF ports for the parameter region) is non-viable on these devices. Since we probe the MEC EC first, we can get away with a smaller reservation that covers the MEC EC ports. If we fall back to classic LPC, we can grow the reservation to cover the memory map and the parameter region. cros_ec_lpc_probe also interacted with I/O ports 0x800-0x807 without a reservation. Restructuring the code to request the MEC LPC region first obviates the need to do so. Signed-off-by: Dustin L.

2022-02-17treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva

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]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ...

2021-01-05platform/chrome: cros_ec_typec: Send mux configuration acknowledgment to ECUtkarsh Patel
In some corner cases downgrade of the superspeed typec device(e.g. Dell typec Dock, apple dongle) was seen because before the SOC mux configuration finishes, EC starts configuring the next mux state. With this change, once the SOC mux is configured, kernel will send an acknowledgment to EC via Host command EC_CMD_USB_PD_MUX_ACK [1]. After sending the host event EC will wait for the acknowledgment from kernel before starting the PD negotiation for the next mux state. This helps to have a framework to build better error handling along with the synchronization of timing sensitive mux states. This change also brings in corresponding EC header updates from the EC code base [1].
