2015-10-25NFC: nci: Allow the driver to set handler for core nci opsRobert Dolca
The driver may be required to act when some responses or notifications arrive. For example the NCI core does not have a handler for NCI_OP_CORE_GET_CONFIG_RSP. The NFCC can send a config response that has to be read by the driver and the packet may contain vendor specific data. The Fields Peak driver needs to take certain actions when a reset notification arrives (packet also not handled by the nfc core). The driver handlers do not interfere with the core and they are called after the core processes the packet.

2015-10-25NFC: nci: Introduce nci_core_cmdRobert Dolca

2015-10-25NFC: nci: Do not call post_setup when setup failsRobert Dolca
The driver should know that it can continue with post setup where setup left off. Being able to execute post_setup when setup fails may force the developer to keep this state in the driver. Signed-off-by: Robert Dolca <robert.dolca@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2015-10-25x86/efi: Fix kernel panic when CONFIG_DEBUG_VIRTUAL is enabledSai Praneeth
When CONFIG_DEBUG_VIRTUAL is enabled, all accesses to __pa(address) are monitored to see whether address falls in direct mapping or kernel text mapping (see Documentation/x86/x86_64/mm.txt for details), if it does not, the kernel panics. During 1:1 mapping of EFI runtime services we access virtual addresses which are == physical addresses, thus the 1:1 mapping and these addresses do not fall in either of the above two regions and hence when passed as arguments to __pa() kernel panics as reported by Dave Hansen here https://lkml.kernel.org/r/5462999A.7090706@intel.com. So, before calling __pa() virtual addresses should be validated which results in skipping call to split_page_count() and that should be fine because it is used to keep track of everything *but* 1:1 mappings.

2015-10-24staging: fbtft: fix voltage settings for C-Berry28Dennis Menschel
This patch fixes some internal voltage settings for the C-Berry28 display. The original example source files for the C-Berry28 as provided by its vendor admatec contained six issues where a command parameter's value didn't match its corresponding comment. I've informed admatec about these discrepancies on 2015-08-25. In the meantime, I've assumed the comments to be more reliable than the code, and thus have used these values to write the initial C-Berry28 driver. After having received a reply from admatec on 2015-10-16 that the issues have been fixed in their example code, it has turned out that for the voltages VCOM and AVDD, the code was indeed correct, but the comments were wrong. This patch is meant to fix these two pending mistakes. Signed-off-by: Dennis Menschel <menschel-d@posteo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
