45  * EC panic is not covered by the standard (0-F) ACPI notify values.
46  * Arbitrarily choosing B0 to notify ec panic, which is in the 84-BF
52  * Command interface between EC and AP, for LPC, I2C and SPI interfaces.
69  * struct cros_ec_command - Information about a ChromeOS EC command.
73  * @insize: Max number of bytes to accept from the EC.
74  * @result: EC's response to the command (separate from communication failure).
75  * @data: Where to put the incoming data from EC and outgoing data to EC.
87  * struct cros_ec_device - Information about a ChromeOS EC device.
91  * @cmd_readmem: Direct read of the EC memory-mapped region, if supported.
104  * @din: Input buffer (for data from EC). This buffer will always be
110  * @dout: Output buffer (for data to EC). This buffer will always be
120  * @cmd_xfer: Send command to EC and get response.
122  *            succeeded, but that doesn't mean the EC was happy with the
123  *            command. The caller should check msg.result for the EC's result
125  * @pkt_xfer: Send packet to EC and get response.
132  * @host_sleep_v1: True if this EC supports the sleep v1 command.
138  *                      is received and when the EC will declare sleep
148  * @notifier_ready: The notifier_block to let the kernel re-query EC
149  *		    communication protocol when the EC sends
151  * @ec: The platform_device used by the mfd driver to interface with the
152  *      main EC.
154  *      PD behind an EC.
155  * @panic_notifier: EC panic notifier.
