12 years agoiio: adc: add new lp8788 adc driver
Kim, Milo [Mon, 17 Sep 2012 09:35:00 +0000 (10:35 +0100)]
iio: adc: add new lp8788 adc driver

 TI LP8788 PMU provides regulators, battery charger, ADC,
 RTC, backlight driver and current sinks.

 This patch enables the LP8788 ADC functions.

 The LP8788 ADC has several ADC input selection and supports 12bit resolution.
 Internal operation of getting ADC is access to registers of LP8788.
 The LP8788 ADC uses exported functions for accessing these registers.
 (exported by LP8788 MFD device driver)

 This driver supports IIO_CHAN_INFO_RAW and SCALE.
 So the IIO consumer can calculate the value with raw and scale.
 The unit of scale is micro.

 (ADC Input Selection)

 Voltage: battery voltage (MAX 5.0, 5.5 and 6.0V)
          charger input voltage
          four general ADC inputs
          coin cell voltage
 Current: battery charging current
 Temperature: IC temperature

 (The IIO map for the IIO consumer)

 The ADC input is configurable in the platform side.
 Even though this platform data is not defined,
 the default IIO map is created for supporting the power supply driver.
 The battery voltage and temperature are used inside this driver.

 (History)

 Patch v6.
 (a) Fix scale value for each ADC input selection
 Voltage and current type are mili unit and temperature is degree.
 To calculate the IC temperature,
 temp = raw * scaleint + (raw * scalepart)/ 1000000, scaleint is always 0.
      = raw * 0.061050, raw: 0 ~ 4095
 Then range of IC temperature(ADC result) is 0 ~ 250'C

 (b) Reorganization of the IIO channel Spec
 Remove address, scan_type and scan_index and rollback the datasheet name.
 The reason why 'address' field is unnecessary is no relation with each channel.
 Moreover, to get the raw ADC value, the address info is not only one register
 but also several registers.
 Therefore specific function(lp8788_get_adc_result) is called rather than
 using one 'address' field.

 (c) Fix coding style
 Remove duplicated checking routine while unregistering the IIO map.
 Fix code for space and parenthesis.

 Patch v5.
 Fix default consumer name as 'lp8788-charger'.
 Add mutex for ADC read operation.
 Reorganization on lp8788_adc_read_raw().

 Patch v4.
 Fix adc_raw function: support RAW and SCALE channel info.
 Change LP8788 ADC platform data - iio map.
 Enables the default IIO map.

 Patch v3.
 Fix wrong size of allocating iio private data.
 Fix coding styles.

 Patch v2.
 Support RAW and SCALE interface for IIO consumer.
 Clean up the iio channel spec macro.

is getting more an more real use and hence people are picking up on
minor issues that made it through review.  Also a related useful set
of utility functions to avoid duplicate code for converting IIO
representations to other forms.

3) a new fractional type for our read_raw / write_raw functions.
  This allows avoiding loss of accuracy via the in kernel interfaces in some
  cases as well as being rather convenient for a lot of range -> scale
  conversions.

4) New AD5755 DAC driver.

5) Some Blackfin timer trigger improvements including hardware pulse control
for device triggering.

6) Support for the ad7091r in the ad7476 driver.

how sampling a single channel ADC via SPI can be implemented and support for the
ad7091r can be added to the driver with just a few adjustments.

The ad7091r requires an external "conversion start" pulse to start a sample
conversion. After the conversion has finished the result can be read via SPI. We
depend on a IIO trigger to generate this signal, as a result only sampling in

12 years agostaging: speakup_soft: Fix reading of init string
Ben Hutchings [Sun, 16 Sep 2012 03:18:50 +0000 (04:18 +0100)]
staging: speakup_soft: Fix reading of init string

softsynth_read() reads a character at a time from the init string;
when it finds the null terminator it sets the initialized flag but
then repeats the last character.

Additionally, if the read() buffer is not big enough for the init
string, the next read() will start reading from the beginning again.
So the caller may never progress to reading anything else.

Replace the simple initialized flag with the current position in
the init string, carried over between calls.  Switch to reading
real data once this reaches the null terminator.

(This assumes that the length of the init string can't change, which
seems to be the case.  Really, the string and position belong together
in a per-file private struct.)
