iio: ad5064: Move bus write callbacks to #if protected sections 2012-07-12T16:57:16+00:00 Lars-Peter Clausen lars@metafoo.de 2012-07-11T08:01:00+00:00 9660ac704ec92ef535bf7c991cb7129b186007a5 Move the SPI and I2C specific write callbacks to the respective "#if IS_ENABLED(CONFIG_SPI_MASTER)" and "#if IS_ENABLED(CONFIG_I2C)" protected sections of the code. This fixes the following warning which occurs if CONFIG_I2C is not set: drivers/iio/dac/ad5064.c: In function ‘ad5064_i2c_write’: drivers/iio/dac/ad5064.c:132: error: implicit declaration of function ‘i2c_master_send’ And the follwing warning which occurs when CONFIG_SPI_MASTER is not set: drivers/iio/dac/ad5064.c:137: warning: ‘ad5064_spi_write’ defined but not used Reported-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org> 
Move the SPI and I2C specific write callbacks to the respective
"#if IS_ENABLED(CONFIG_SPI_MASTER)" and "#if IS_ENABLED(CONFIG_I2C)"
protected sections of the code.

This fixes the following warning which occurs if CONFIG_I2C is not set:
	drivers/iio/dac/ad5064.c: In function ‘ad5064_i2c_write’:
	drivers/iio/dac/ad5064.c:132: error: implicit declaration of function ‘i2c_master_send’

And the follwing warning which occurs when CONFIG_SPI_MASTER is not set:
	drivers/iio/dac/ad5064.c:137: warning: ‘ad5064_spi_write’ defined but not used

iio:dac:ad5064: Add support for the ad5629r and ad5669r 2012-06-30T09:15:09+00:00 Lars-Peter Clausen lars@metafoo.de 2012-06-26T09:04:36+00:00 6a17a0768f77626046aa441843b318a00bac3800 The ad5629r and ad5669r are the I2C variants of the ad5628 and ad5668. Since the ad5064 driver currently only supports SPI based devices the major part of this patch focuses on adding support for I2C based devices. Adding support for the actual parts boils down to adding entries for them to the device id table.
