media: cros-ec-cec: Get number of CEC ports from EC 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.

media: cros-ec-cec: Support receiving messages from multiple ports 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.

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.

platform/chrome: cros_ec_lpcs: reserve the MEC LPC I/O ports first 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.

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.

mfd / platform: cros_ec: Reorganize platform and mfd includes There is a bit of mess between cros-ec mfd includes and platform includes. For example, we have a linux/mfd/cros_ec.h include that exports the interface implemented in platform/chrome/cros_ec_proto.c. Or we have a linux/mfd/cros_ec_commands.h file that is non related to the multifunction device (in the sense that is not exporting any function of the mfd device). This causes crossed includes between mfd and platform/chrome subsystems and makes the code difficult to read, apart from creating 'curious' situations where a platform/chrome driver includes a linux/mfd/cros_ec.h file just to get the exported functions that are implemented in another platform/chrome driver. In order to have a better separation on what the cros-ec multifunction driver does and what the cros-ec core provides move and rework the affected includes doing: - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c driver from include/linux/mfd/cros_ec.h to a new file include/linux/platform_data/cros_ec_proto.h - Update all the drivers with the new includes, so - Drivers that only need to know about the protocol include - linux/platform_data/cros_ec_proto.h - linux/platform_data/cros_ec_commands.h - Drivers that need to know about the cros-ec mfd device also include - linux/mfd/cros_ec.h Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mark Brown <broonie@kernel.org> Acked-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Neil Armstrong <narmstrong@baylibre.com> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> Tested-by: Gwendal Grignou <gwendal@chromium.org> Series changes: 3 - Fix dereferencing pointer to incomplete type 'struct cros_ec_dev' (lkp) Signed-off-by: Lee Jones <lee.jones@linaro.org>
