According to the datasheet and as defined in struct bmp280_comp_press, dig_p1 is of type u16, while dig_p2 to dig_p9 are of type s16. In bmp280_read_compensation_press(), values read from the device were treated as the wrong type. In bmp280_read_press() the fractional part of the measured pressure is calculated wrong. A better way is to use *val for the raw pressure and *val2 for the quotient and let the core do the proper conversion using IIO_VAL_FRACTIONAL. Signed-off-by:

The ADC on exynos7 is quite similar to ADCv2. The differences are as follows: - exynos7-adc has 8 input channels (as against 10 in ADCv2). - exynos7 does not include an ADC PHY control register. - Some ADC_CON2 register bits being used in ADCv2 are listed as reserved in exynos7-adc. This results in a different init_hw function for exynos7. Signed-off-by:

Instead of using the ADC_PHY register base address, use sysreg phandle in ADC node to control ADC_PHY configuration register. This patch adds syscon node for Exynos3250, Exynos4x12, Exynos5250, and Exynos5420, Exynos5800. Signed-off-by:

This inline helper function has been replaced with comedi_bytes_per_sample(). The same commit (bf33eb4b) introduced a couple other related helper functions a manipulate the sample size. Use the new helper functions to remove the use of 'bytes_per_sample()' and remove it. Signed-off-by:

This member of the private data is replicating what the comedi_async 'cur_chan' member is used for. Use that instead and remove the private data member. Signed-off-by:
-
H Hartley Sweeten authored
The commedi_async 'cur_chan' member is used to track the current position in the chanlist for a scan. Currently only a couple comedi drivers use this member. For aeshtetics, move the 'cur_chan' tracking into the core for non-SDF_PACKED subdevices. The 'cur_chan' will be updated after reading or writing samples to the async buffer by comedi_inc_scan_progress(). All non-SDF_PACKED subdevices will then automatiaclly track the 'cur_chan'. Some of the drivers use the 'cur_chan' to detect the end of scan event when counting scans. The COMEDI_CB_EOS event is automatically added by the core when the end of scan is detected. The drivers just need to check if the 'cur_chan' is 0 to count the number of scans completed. Signed-off-by:

For some unfathomable reason, the Comedi `insn_bits` handler for the digital output subdevice (`icp_multi_insn_bits_do()`) writes the digital output register and reads back the unrelated digital input register. Read back the current state of the outputs (held in `s->state`) instead. Signed-off-by:

Currently this driver uses a bitmap in the private data to keep track of the unipolar/bipolar range for each channel. This is needed to determine if the data needs to be munged for bipolar samples. Remove this member from the private data and use the comedi core helper function comedi_range_is_bipolar() to determine if the data needs to be munged. Signed-off-by:

H Hartley Sweeten authored
This functions uses the async->cur_chan to determine if the current channel is using a bipolar range and the sample needs to be munged. The cur_chan is never incremented so all the samples are munged based on the fist channel in the cmd->chanlist. Bump the cur_chan after writing each sample. This fixes the code so that the munging will be done correctly. Signed-off-by:

The comedi core calls comedi_buf_reset() before starting an async command (*do_cmd) and after returning a subdevice to an idle state (*cancel). The drivers do not need to reset the async->cur_chan in those functions. Signed-off-by:

`do_bufinfo_ioctl()` handled the `COMEDI_BUFINFO` ioctl. It is supposed to update the read or write positions in the buffer depending on the direction of data transfer set up by the asynchronous command. Currently it checks the `SDF_CMD_READ` and `SDF_CMD_WRITE` subdevice flags. That's fine for most subdevices - the ones that only support one direction, but is incorrect for those subdevices that allow the command to be set up in either direction. Since we now set the `CMDF_WRITE` flag according to the data transfer direction of the current command running on the subdevice, check that flag instead. Signed-off-by:

`comedi_poll()` handles the poll() file operation for comedi devices. If no asynchronous command has been set up on the current "read" subdevice, it sets the `POLLIN` and `POLLRDNORM` bits in the return value to indicate that the read() file operation would not block as it would return an error. Add a check so it also does that if the asynchronous command has been set up in the "write" direction as that also causes the read() file operation to return an error. Similarly, if no asynchronous command has need set up on the current "write" subdevice, it sets the `POLLOUT` and `POLLWRNORM` bits in the return value to indicate that the write() file operation would not block as it would return an error. Add a check so it also does that if the asynchronous command has been set up in the "read" direction as that also causes the write() file operation to return an error. Signed-off-by:
