2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.

2016-10-04mfd: altera-a10sr: Make it explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_ALTERA_A10SR drivers/mfd/Kconfig: bool "Altera Arria10 DevKit System Resource chip" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since builtin_driver() uses the same init level priority as module_spi_driver() the init ordering remains unchanged with this commit. [Note that there is no builtin_spi_driver macro, so we open-code what it would be via builtin_driver().] Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.
