Input: synaptics-rmi4 - remove unnecessary flush_workqueue()

2022-04-25T01:25:09Z

All work currently pending will be done first by calling destroy_workqueue, so there is unnecessary to flush it explicitly. Reported-by: Zeal Robot Signed-off-by: ran jianping Link: https://lore.kernel.org/r/20220422093304.2781183-1-ran.jianping@zte.com.cn Signed-off-by: Dmitry Torokhov

media: Kconfig: cleanup VIDEO_DEV dependencies

2022-03-18T04:58:35Z

media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

Input: synaptics-rmi4 - Fix device hierarchy

2021-11-06T02:46:21Z

The created rmi device is orphan, which breaks the real device hierarchy, and can cause some trouble, especially during suspend and resume sequences. E.g. in case of I2C, rmi dev should be child of the I2C client device. Fix this, assigning the transport device as parent of the rmi device.

Input: synaptics-rmi4 - use new structure for SPI transfer delays

2020-12-11T07:39:16Z

In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).
