| * mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra2019-09-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* extcon: max8997: Fix lack of path setting in USB device modeMarek Szyprowski2018-11-141-6/+4
| | | | | | | | | | | | | | MAX8997 driver disables automatic path selection from MicroUSB connector and manually sets path to either UART or USB lines. However the code for setting USB path worked only for USB host mode (when ID pin is set to ground). When standard USB cable (USB device mode) is connected, path registers are not touched. This means that once the non-USB accessory is connected to MAX8997-operated micro USB port, the path is no longer set to USB and USB device mode doesn't work. This patch fixes it by setting USB path both for USB and USB host modes. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
* extcon: max8997: Avoid forcing UART path on drive probeMarek Szyprowski2018-11-121-2/+13
| | | | | | | | | | | | | | | | | | Driver unconditionally forces UART path during probe, probably to ensure that one can get kernel serial log as soon as possible. This approach causes some issues, especially when board is booted with non-UART cable connected to micro-USB port. For example, when USB cable is connected, UART TX/RX lines are unconditionally short-circuited to USB D+/D- lines. This is in turn recognized by a series of serial BREAK signals and some random characters when USB host tries to perform enumeration procedure. To solve the above issue and keep UART console operational as early as possible, set UART path only when USB ID reports UART capable cable.

Release locking when sending the connector state in extcon_sync() - Previously, extcon used the spinlock before calling the notifier_call_chain to prevent the scheduled out of task and to prevent the notification delay. When spinlock is locked for sending the notification, deadlock issue occured on the side of extcon consumer device. To fix this issue on extcon consumer device, release locking when sending the connector state. 2. Fix minor issues of extcon provider driver - extcon-intel-int3496.c uses 'linux/gpio/consumer.h' instead of 'linux/gpio.h' - extcon-usbc-cors-ec.c adds SPDX license and fix the wrong license information
