2012-03-16Input: convert I2C drivers to use module_i2c_driver()Axel Lin1-11/+1
This patch converts the drivers in drivers/input/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-11-30Input: ad7879-i2c - use swapped variant of i2c_smbus_read_word_dataJonathan Cameron1-2/+2
This variant was introduced in i2c: boilerplate function for byte swapped smbus_write/read_word_data This also has the side effect of ensuring any errors from the i2c read and no longer mangled.

2011-11-29Input: ad7879-i2c - remove redundant MODULE_ALIASAxel Lin1-1/+0
MODULE_DEVICE_TABLE will setup the module alias for us, thus adding MODULE_ALIAS for an entry already in MODULE_DEVICE_TABLE is redundant. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-11-15Input: ad7879 - consolidate PM methodsDmitry Torokhov1-25/+1
The PM methods are basically the same for SPI and I2C busses, so let's use the same dev_pm_ops for both of them. Acked-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-10-06Input: ad7879-i2c - wrap suspend and resume in CONFIG_PM_SLEEPDmitry Torokhov1-4/+2
CONFIG_PM is defined when CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined, however suspend and resume methods are only valid in the context of CONFIG_PM_SLEEP. If only CONFIG_PM_RUNTIME is defined we get the following warning (courtesy of Geerts randconfig builds): ad7879-i2c.c: warning: 'ad7879_i2c_resume' defined but not used Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-01-06Input: ad7879 - convert I2C to dev_pm_opsMark Brown1-7/+10
There is a general move towards the use of dev_pm_ops rather than bus specific suspend APIs as this simplifies both the bus and PM core implementations. Convert the ad7879-ts I2C support over. Compile tested only. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-07-03Input: ad7879 - use i2c_smbus_read_i2c_block_data() to lower overheadMichael Hennerich1-1/+4
Avoid additional addressing overhead incurred by word_data transfers. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-07-03Input: ad7879 - split bus logic outMike Frysinger1-0/+140
The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously.
