* x86/platform: Make atom/pmc_atom.c explicitly non-modularPaul Gortmaker2015-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: config PMC_ATOM def_bool y ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_init() translates to device_initcall() in the non-modular case, the init ordering remains unchanged with this commit. We leave some tags like MODULE_AUTHOR() for documentation purposes. Also note that MODULE_DEVICE_TABLE() is a no-op for non-modular code. We correct a comment that indicates the data was only used by that macro, as it actually is used by the code directly.

* x86/platform/intel/pmc_atom: Move the PMC-Atom code to arch/x86/platform/atomAndy Shevchenko2015-07-06
| | | | | | | | | | | | | | | | | | This is specific driver for Intel Atom SoCs like BayTrail and Braswell. Let's move it to dedicated folder and alleviate a arch/x86/kernel burden. There is no functional change.

* x86/platform/atom/punit: Add Punit device state debug driverSrinivas Pandruvada2015-05-07
The patch adds a debug driver, which dumps the power states of all the North complex (NC) devices. This debug interface is useful to figure out the devices, which blocks the S0ix transitions on the platform. This is extremely useful during enabling PM on customer platforms and derivatives.
