2017-10-13mfd: stw481x: Make three arrays static const, reduces object code sizeColin Ian King1-4/+6
Don't populate the arrays vcore_val, vpll_val and vaux_val on the stack, instead make them static const. Makes the object code smaller by over 370 bytes: Before: text data bss dec hex filename 6971 3248 64 10283 282b drivers/mfd/stw481x.o After: text data bss dec hex filename 6338 3504 64 9906 26b2 drivers/mfd/stw481x.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Use devm_mfd_add_devices() for MFD devices registration and get rid of .remove callback to remove MFD child-devices. This is done by managed device framework.

2015-08-11mfd: stw481x: Export I2C module alias informationJavier Martinez Canillas1-0/+1
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.
