2019-09-02mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra1-2/+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>

SIMPLE_DEV_PM_OPS() already implies const for the type; drop the extra modifier. Fixes: eb1aac4c8744f75460c34d71b0c73bebf3e8ee5c ("HID: google: add support tablet mode switch for Whiskers") Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2018-10-09HID: google: add support tablet mode switch for WhiskersDmitry Torokhov1-19/+394
Whiskers is a foldable base, and thus requires combining "base presence" signal coming from EC with base state signal (folded/unfolded) coming from USB/HID interface to produce proper SW_TABLET_MODE event.

2018-03-28HID: google: Enable PM Full On mode when adjusting backlightHaridhar Kalvala1-0/+14
hammer LED backlight brightness is not getting set when USB device is in suspend state. This patch fixes the issue by requesting USB HID device to be in FULLON mode, so that sending hardware output report and hardware raw request won't fail to set brightness, and set device back to NORMAL mode once this call returns.
