2012-01-24NFC: Free sk_buff if nfcwilink_send failsIlan Elias1-2/+4
Free sk_buff if nfcwilink_send fails. Signed-off-by: Ilan Elias <ilane@ti.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24NFC: Download TI NFC init scriptIlan Elias1-4/+284
Download TI NFC init script during nfcwilink open operation, after the NFC channel is registered with TI shared transport. TI NFC init script is written in BTS format. First, read the chip version via a special vendor specific command. Second, we request the relevant BTS file from the user space, and then send the BTS commands to the chip.

2011-12-14NFC: Set and get DEP general bytesSamuel Ortiz1-1/+6
Without an API for setting and getting the local and remote general bytes, drivers won't be able to properly establish a DEP link. This API also allows them to propagate the remote general bytes they get from the DEP link establishment up to the LLCP layer.

2011-12-14NFC: Add tx skb allocation routineSamuel Ortiz1-1/+1
This is a factorization of the current rawsock tx skb allocation routine, as it will be used by the LLCP code. We also rename nfc_alloc_skb to nfc_alloc_recv_skb for consistency sake. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

It is not used outside this driver so no need to make the symbol global. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-18USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman1-18/+1
This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

2011-11-01drivers/nfc: add module.h to nfcwilink.cPaul Gortmaker1-0/+1
This is a full module, with module_init() and module_exit() and so it needs module.h called out for inclusion. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-02-26drivers/nfc/pn544.c: add missing regulatorMatti J. Aaltonen1-1/+3
The regulator framework is used for power management. The regulators are only named in the driver code, the actual control stuff is in the board file for each architecture or use case. The PN544 chip has three regulators that can be controlled or not - depending on the architecture where the chip is being used. So some of the regulators may not be controllable. In our current case the third regulator, which was missing from the code, went unnoticed because we didn't need to control it. To be as general as possible - in this respect - the driver needs to list all regulators. Then the board file can be used to actually set the usage. Signed-off-by: Matti J.
