iio: light: rpr0521: add missing Kconfig dependencies

2022-12-08T10:23:02Z

[ Upstream commit 6ac12303572ef9ace5603c2c07f5f1b00a33f580 ] Fix an implicit declaration of function error for rpr0521 under some configs When CONFIG_RPR0521 is enabled without CONFIG_IIO_TRIGGERED_BUFFER, the build results in "implicit declaration of function" errors, e.g., drivers/iio/light/rpr0521.c:434:3: error: implicit declaration of function 'iio_trigger_poll_chained' [-Werror=implicit-function-declaration] 434 | iio_trigger_poll_chained(data->drdy_trigger0); | ^~~~~~~~~~~~~~~~~~~~~~~~ This fix adds select dependencies to RPR0521's configuration declaration.

iio: light: fix kconfig dependency bug for VCNL4035

2020-11-24T12:29:21Z

commit 44a146a44f656fc03d368c1b9248d29a128cd053 upstream. When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER Depends on [n]: IIO [=y] && IIO_BUFFER [=n] Selected by [y]: - VCNL4035 [=y] && IIO [=y] && I2C [=y] The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on IIO_BUFFER. This can also fail building the kernel. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.

iio: light: add driver for MAX44009

2019-02-02T15:47:46Z

The MAX44009 is a low-power ambient light sensor from Maxim Integrated. It differs from the MAX44000 in that it doesn't have proximity sensing and that it requires far less current (1 micro-amp vs 5 micro-amps). The register mapping and feature set between the two are different enough to require a new driver for the MAX44009. Developed and tested with a BeagleBone Black and UDOO Neo (i.MX6SX) Supported features: * Reading lux (processed value) * Rising and falling illuminance threshold events * Configuring integration time https://datasheets.maximintegrated.com/en/ds/MAX44009.pdf Signed-off-by: Robert Eshleman Signed-off-by: Jonathan Cameron

iio: light: Add support for vishay vcnl4035

Add support for VCNL4035, which is capable of Ambient light sensing (ALS) and proximity function. This patch adds support only for ALS function Signed-off-by: Parthiban Nallathambi Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: vcnl4000: add support for VCNL4200

2018-07-29T11:19:28Z

VCNL4200 is an integrated long distance (up to 1500mm) proximity and ambient light sensor. The support is very basic. There is no configuration of proximity and ambient light sensing yet. Only the reading of both measured values is done. The reading of ambient light and proximity values is blocking. If you request a new value too early, the driver waits for new value to be ready.
