2019-12-09extcon: arizona: Factor out microphone and button detectionCharles Keepax1-44/+71
Continue refactoring the microphone detect handling by factoring out the handling for microphone detection and button detection into separate functions. This both makes the code a little clearer and prepares for some planned future refactoring to make the state handling in the driver more explicit.

It makes sense to clear the internal state of the jack detection regardless of if the headphone detect based accessory detection or the normal microphone detect based flow is used.

2019-10-11extcon: sm5502: Reset registers during initializationStephan Gerhold2-0/+6
On some devices (e.g. Samsung Galaxy A5 (2015)), the bootloader seems to keep interrupts enabled for SM5502 when booting Linux. Changing the cable state (i.e. plugging in a cable) - until the driver is loaded - will therefore produce an interrupt that is never read. In this situation, the cable state will be stuck forever on the initial state because SM5502 stops sending interrupts. This can be avoided by clearing those pending interrupts after the driver has been loaded. One way to do this is to reset all registers to default state by writing to SM5502_REG_RESET. This ensures that we start from a clean state, with all interrupts disabled.

2019-09-02mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra1-1/+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>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc update part 2 from Greg KH: "Here is the "real" big set of char/misc driver patches for 5.2-rc1 Loads of different driver subsystem stuff in here, all over the places: - thunderbolt driver updates - habanalabs driver updates - nvmem driver updates - extcon driver updates - intel_th driver updates - mei driver updates - coresight driver updates - soundwire driver cleanups and updates - fastrpc driver updates - other minor driver updates - chardev minor fixups Feels like this tree is getting to be a dumping ground of "small driver subsystems" these days. Which is fine with me, if it makes things easier for those subsystem maintainers.

2019-04-12extcon: arizona: Disable mic detect if running when driver is removedCharles Keepax1-0/+10
Microphone detection provides the button detection features on the Arizona CODECs as such it will be running if the jack is currently inserted. If the driver is unbound whilst the jack is still inserted this will cause warnings from the regulator framework as the MICVDD regulator is put but was never disabled. Correct this by disabling microphone detection on driver removal and if the microphone detection was running disable the regulator and put the runtime reference that was currently held.
