2019-12-13Input: imx_sc_key - only take the valid data from SCU firmware as key stateAnson Huang
When reading key state from SCU, the response data from SCU firmware is 4 bytes due to MU message protocol, but ONLY the first byte is the key state, other 3 bytes could be some dirty data, so we should ONLY take the first byte as key state to avoid reporting incorrect state.

2019-11-25Input: snvs_pwrkey - send key events for i.MX6 S, DL and QRobin van der Gracht
The first generation i.MX6 processors does not send an interrupt when the power key is pressed. It sends a power down request interrupt if the key is released before a hard shutdown (5 second press). This should allow software to bring down the SoC safely. For this driver to work as a regular power key with the older SoCs, we need to send a keypress AND release when we get the power down request irq.

2019-09-02mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra
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>

2019-08-06Input: applespi - use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct touchpad_protocol { ... struct tp_finger fingers[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*tp) + tp->number_of_fingers * sizeof(tp->fingers[0]); with: struct_size(tp, fingers, tp->number_of_fingers) This code was detected with the help of Coccinelle.

2019-07-19Input: add Apple SPI keyboard and trackpad driverRonald Tschalär
The keyboard and trackpad on recent MacBook's (since 8,1) and MacBookPro's (13,* and 14,*) are attached to an SPI controller instead of USB, as previously. The higher level protocol is not publicly documented and hence has been reverse engineered. As a consequence there are still a number of unknown fields and commands. However, the known parts have been working well and received extensive testing and use. In order for this driver to work, the proper SPI drivers need to be loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci; for all others they are spi_pxa2xx_platform and intel_lpss_pci.

2019-07-11Input: mtk-pmic-keys - add of_node_put() before returnNishka Dasgupta
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in three places. Issue found with Coccinelle.

Instead of hardcoding the input name to the driver name ('gpio-keys-polled'), allow specifying the name of the device via "label" property. If the property is not present (nor name is set in board-supplied platform data), we'll default to the old name.

2019-06-22Input: gpio_keys - use struct_size() in devm_kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct gpio_keys_drvdata { ... struct gpio_button_data data[0]; }; size = sizeof(struct gpio_keys_drvdata) + count * sizeof(struct gpio_button_data); instance = devm_kzalloc(dev, size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, data, count), GFP_KERNEL); Notice that, in this case, variable size is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
