HUTRR72 added 3 new usage codes for keys that are supposed to enable, disable and toggle camera access. These are useful, considering many laptops today have key(s) for toggling access to camera. This patch adds new key definitions for KEY_CAMERA_ACCESS_ENABLE, KEY_CAMERA_ACCESS_DISABLE and KEY_CAMERA_ACCESS_TOGGLE. Additionally hid-debug is adjusted to recognize this new usage codes as well.

Since commit 0166dc11 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. Signed-off-by:

The raydium I2C touchscreen driver is currently manually managing the wake IRQ. This change removes the explicit enable_irq_wake / disable_irq_wake and instead relies on the PM subsystem. This is done by calling dev_pm_set_wake_irq. i2c_device_probe already calls dev_pm_set_wake_irq when using device tree, and i2c_device_remove also already calls dev_pm_clear_wake_irq. There could be some device tree systems that have incorrectly declared `wake` capabilities, so this change will set the wake irq if one is missing. This matches the previous behavior. Signed-off-by:

pwm_request() isn't recommended to be used any more because it relies on global IDs for the PWM which comes with different difficulties. The new way to do things is to find the right PWM using a reference from the platform device. (This can be created either using a device-tree or a platform lookup table, see e.g. commit 5a4412d4 ("ARM: pxa: tavorevb: Use PWM lookup table") how to do this.) There are no in-tree users, so there are no other code locations that need adaption. Signed-off-by:

As can be seen in elants_i2c_power_off(), we want the reset GPIO asserted when power is off. The reset GPIO is active low so we need the reset line logic low when power is off to avoid leakage. We have a problem, though, at probe time. At probe time we haven't powered the regulators on yet but we have: devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW); While that _looks_ right, it turns out that it's not. The GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the GPIO to "not asserted". Since this is an active low GPIO that inits it to be high. Let's fix this to properly init the GPIO. Now after both probe and power off the state of the GPIO is consistent (it's "asserted" or level low). Once we fix this, we can see that at power on time we no longer to assert the reset GPIO as the first thing. The reset GPIO is _always_ asserted before powering on. Let's fix powering on to account for this. Fixes: afe10358 ("Input: elants_i2c - wire up regulator support") Signed-off-by:

The fixp_sin32_rad() contains a call to BUG_ON(). If users of fixp-arith.h have not included the bug.h prior including the fixp-arith.h the compiler will not find the BUG_ON. Thus every user of fixp-arith.h must also include bug.h (or roll own variant of BUG_ON()).

This patch adds support for Himax hx83112b touchscreen devices. As there are no publicly available data sheets for these devices, the implementation is based on the driver of the downstream Android kernel used in the Fairphone 3. This patch is a complete rewrite, though, and the code bears no resemblence to the original implementation. The driver has been tested on the aforementioned phone. Signed-off-by:

The Allwinner F1C100s series of SoCs contain a LRADC (aka. KEYADC) compatible to the version in other SoCs. The manual doesn't mention the ratio of the input voltage that is used, but comparing actual measurements with the values in the register suggests that it is 3/4 of Vref. Add an F1C100s compatible string to the list, and pair it with the A83T fallback. Since the A64 is the same, combined both using an enum. Signed-off-by:

Some Pin/GPIO controllers can't get current GPIO status when interrupt mode is set. Specifically Ingenic's JZ4755 always returns status at the moment of interrupt. The patch tries to fix that by forcibly setting pin mode to GPIO input prior to reading actual row status. enable_row_irqs seems to set interrupt mode back as it should be. Signed-off-by:

This is the basic driver for the Cypress TrueTouch Gen5 touchscreen controllers. This driver supports only the I2C bus but it uses regmap so SPI support could be added later. The touchscreen can retrieve some defined zone that are handled as buttons (according to the hardware). That is why it handles button and multitouch events. Reviewed-by:

Add support for the Hynitron cst3xx controller found on devices such as the Anbernic RG353P and RG353V (the Hynitron CST340). This driver was built from sources provided by Hynitron to Anbernic (possibly via Rockchip as an intermediary) and marked as GPLv2 in the code. This driver was written strictly for the cst3xx series, but in most places was left somewhat generic so support could be easily added to other devices in the future. Signed-off-by:
