2019-08-27staging: greybus: fix up SPDX comment in .h filesGreg Kroah-Hartman1-1/+1
When these files originally got an SPDX tag, I used // instead of /* */ for the .h files. Fix this up to use // properly.

2017-11-11staging: greybus: add SPDX identifiers to all greybus driver filesGreg Kroah-Hartman1-0/+1
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/staging/greybus files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2016-07-21greybus: spilib: make spilib independent of gbphyViresh Kumar1-1/+7
spilib is used by multiple users currently (spi.c and fw-core.c) but commit aa52b62a0556 broke that hierarchy and introduced gbphy dependent code in spilib. This may have unreliable consequences as we are doing following operation unconditionally now: gbphy_dev = to_gbphy_dev(spi->parent); gbphy_runtime_get_sync(gbphy_dev); which may not go well when the parent is of type &bundle->dev (fw-core.c). This patch introduces spilib_ops and lets the users of the core register them. This shall have no functional change for the spi.c usecase and shall fix the unreliable results for the fw-core.c usecase. Tested by writing to mtd0 dev and verifying (with print messages) that the below routines are getting called for a gpbridge-test module.

2016-05-14greybus: spi: Restructure spi.c to share it with other bundle driversViresh Kumar1-0/+18
This patch restructures spi.c as spilib core, so that the same logic can be reused for SPI connections implemented as part of different bundle types. This is required for Firmware Management Bundle. Note that the 'struct gb_protocol' and its callback aren't moved to a separate file in this commit to make its reviews easier. That will be done by a following patch.
