drivers: misc: ti_dac7512: Remove duplicate driver

2017-09-13T16:49:57+00:00

The Texas Instruments DAC7512 has the exact same pinout, programming interface and power-down modes as the Texas Instruments DAC121S101 and Analog Devices AD5320, which are already supported by the IIO driver ad5446.c. Remove the duplicate misc driver. This requires user space to migrate to the standardized IIO sysfs ABI. (In other words, it needs to change a filename.) The IIO driver supports the chip's features more fully, e.g. the ability to power down the output or choose one of the available powerdown modes. There is an oddity with the misc driver in that it initializes the SPI slave to SPI_MODE_0, in contradiction to the datasheet which specifies that data is latched in on the falling edge, implying that SPI_MODE_1 or SPI_MODE_2 must be used. Another oddity is that Kconfig and the MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it actually has 12-bit.

spi: Drop owner assignment from spi_drivers

2015-10-28T01:30:17+00:00

An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis Acked-by: Jonathan Cameron Signed-off-by: Mark Brown

drivers/misc: delete non-required instances of include

2014-02-07T23:10:19+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

drivers: misc: ti_dac7512: add support for DT matching

2013-09-26T16:04:06+00:00

Only matching is done via DT, no other details can be passed. Signed-off-by: Daniel Mack Signed-off-by: Greg Kroah-Hartman

drivers: misc: ti_dac7512: provide a SPI ID table

2013-09-26T16:04:06+00:00

This way, the module can be autoloaded by the SPI core. Signed-off-by: Daniel Mack Signed-off-by: Greg Kroah-Hartman

drivers: misc: ti_dac7512: drop DAC7512_DRV_NAME

2013-09-26T16:04:05+00:00

The driver's name can be provided directly, so drop the #define. Signed-off-by: Daniel Mack Signed-off-by: Greg Kroah-Hartman

drivers: misc: ti_dac7512: drop module version

2013-09-26T16:04:05+00:00

Providing a module version doesn't add any value, so drop it. Signed-off-by: Daniel Mack Signed-off-by: Greg Kroah-Hartman

misc: replace strict_strtoul() with kstrtoul()

2013-06-06T19:54:08+00:00

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Reviewed-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

misc: remove use of __devexit

2012-11-21T20:53:32+00:00

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton Cc: "Michał Mirosław" Cc: Wolfram Sang Cc: Eric Piel Cc: Jiri Slaby Signed-off-by: Greg Kroah-Hartman
