wilco_ec_mailbox

Send a command request to the EC mailbox and receive the response.

@type: Mailbox message type, see enum above @command: Command to execute @request_data: Request data buffer @request_size: Number of bytes in request data buffer (max 32) @response_data: Response data buffer @response_size: Number of bytes in response data buffer (max 32)

Returns

number of bytes received, negative error code on failure

wilco_ec_sendrecv

Send a basic EC command with a one byte parameter, ignoring the first byte of returned data to match the common behavior. The maximum response size is 31 due to the ignored byte.

@command: Command to execute

Parameters

Command parameter to send @data: Response data buffer @size: Number of bytes in response data buffer (max 31)

Returns

number of bytes received, negative error code on failure
