Move ad7780 ADC driver out of staging and into the mainline. The ad7780 is a sigma-delta analog to digital converter. This driver provides reading voltage values and status bits from both the ad778x and ad717x series. Its interface also allows writing on the FILTER and GAIN GPIO pins on the ad778x. Signed-off-by:

Renato Lui Geh authored
The ad7780 supports both the ad778x and ad717x families. Each chip has a corresponding ID. This patch provides a mask for extracting ID values from the status bits and also macros for the correct values for the ad7170, ad7171, ad7780 and ad7781. Signed-off-by:
-
Renato Lui Geh authored
The AD7780 driver contains status pattern bits designed for checking whether serial transfers have been correctly performed. Pattern macros were previously generated through bit fields. This patch sets good pattern values directly and masks through GENMASK. Signed-off-by:

Renato Lui Geh authored
This patch adds the new feature of reading the filter odr value for ad778x chips. This value is stored in the chip's state struct whenever a read or write call is performed on the chip's driver. This feature requires sharing SAMP_FREQ. Since the ad717x does not have a filter option, the driver only shares the relevant info mask for the ad778x family. Signed-off-by:

This patch adds a new functionality of reading gain values from the ad778x chips. This value is stored in the chip's state struct and is updated whenever a read or write call is performed on the driver. Signed-off-by:

As most of the other ADC the lpc32xx one use a vref-supply property: document it. Reviewed-by:

Gregory CLEMENT authored
Until now this driver only exposed the raw value of the channels. With this patch, the scale value is also exposed. It depends of a regulator supply, and unlike most of the other driver, do not having this regulator won't prevent to use the driver. The reason for it is to allow to continue to use this driver with an old device tree. If there is no regulator supply then the scale won't be exposed. Signed-off-by:

This patch will remove platform data members and replace them with device tree properties. These properties will be subject to further modifications and probably replaced with other functionalities at some point in time. Signed-off-by:

This patch replaces the platform data clock select member with DT clock binding. Through the DT the external clock binding is specified. If this is not provided then the device will use the internal clock source. With the external clock binding there is the option to use a clock or a crystal as the clock source. When an external crystal is used it is connected to MCLK1 and MCLK2 pins. If the external clock is used only MCLK2 pin will be connected. Signed-off-by:

The BMP280/BME280 calibration data should also go into the entropy pool, like we do for BMP180. This just adds the temperature and pressure calibration, the humidity calibration seems like too much annoying calls to add.

Add documentation for optional use of external clock. All devices supported by this driver can work with an external clock in sync mode. Another mode, called Pulse Per Second (PPS) is supported only by adis1649x devices. The mode is selected by using the "clock-names" property. The pin which is used as external clock input is selected by using a custom optional property called "adi,ext-clk-pin". If this field is left empty, DIO2 is assigned as default external clock input pin. Signed-off-by:

Inertial sensor data collection and processing can be controlled by configuring one of the DIOx lines as an external clock input. This option is available for all devices supported by this driver. However, only adis1649x devices support different modes for the external clock. Sync mode is supported by all devices. In this mode, the output data rate is equal with the clock frequency divided by DEC_RATE + 1. This mode of calculation is similar with the case when the internal clock is used. Pulse Per Second (PPS) Mode, is only supported by adis1649x devices. In this mode, the output data rate is equal to the product of the external clock frequency and the scale factor in the SYNC_SCALE register. This patch uses the "clock-names" property to enable the external clock in one of the two supported modes: "sync" or "pps". This property is optional. If it is not specified, the internal clock is used. This patch also offers the option to select the DIOx line to be used as an external clock input via the custom "adi,ext-clk-pin" property. If this field is left empty, DIO2 is assigned as default external clock input pin. Each DIOx pin supports only one function at a time (data ready line selection or external clock input).

indio_dev->mlock is intended to protect state transitions in the core. It's scope is tightly defined. For device specific uses such as those made here, we should define a local lock allowing the scope of the lock to be defined near to what it is protecting. These mlock changes can be non obvious, but given we don't do anything other than direct for DACs, these ones are easy to do. If anyone wants to help with this particular effort it would be most welcome! Signed-off-by:
