Linus Torvalds 2bd8040174 This is the bulk of GPIO changes for the v4.12 kernel cycle: ... Core changes - Return NULL from gpiod_get_optional() when GPIOLIB is disabled. This was a much discussed change. It affects use cases where people write drivers that might or might not be using GPIO resources. I have decided that this is the lesser evil right now. - Make gpiod_count() behave consistently across different hardware descriptions. - Fix the syntax around open drain/open source to not infer active high/low semantics. New drivers - A new single-register fixed-direction framework driver for hardware that have lines controlled by a single register that just work in one direction (out or in), including IRQ support. - Support the Fintek F71889A GPIO SuperIO controller. - Support the National NI 169445 MMIO GPIO. - Support for the X-Gene derivative of the DWC GPIO controller - Support for the Rohm BD9571MWV-M PMIC GPIO controller. - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver and replace both the Gemini and the Moxa ART custom drivers with this driver. Driver improvements - A whole slew of drivers have their spinlocks chaned to raw spinlocks as they provide irqchips, and thus we are progressing on realtime compliance. - Use devm_irq_alloc_descs() in a slew of drivers, getting managed resources. - Support for the embedded PWM controller inside the MVEBU driver. - Debounce, open source and open drain support for the Aspeed driver. - Misc smaller fixes like spelling and syntax and whatnot. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJZCusBAAoJEEEQszewGV1zengP/i3YgmSXJdaf26t/NxG3klU3 qx3akdQ3gEQ6BOlIY7Ew+b6qgMJynYNZa1trZgqTgLxPEKWjidyCgz+LHQ0OY+ir a7x6wr+gBj5WlgV+nBjVs4l6W8pVKCfnap/04OPEQDpxZOHs2LU5pqxxUZ9AxkKS urDFMDX55baFviQ+xAuHgamok87YoGP36A/e/fHIBepZmnochf0mCcPfIh0t8lRh s2x29PN5ZFRkl403RzjZfVCEMr9bMnSqmDquvPO++Kq0bL+3rOhuMErocd1Bg8ao LxBktkryujTaw699xK7Rq5SwcnOAPpaBY4NTmwsIJvAJuCh7qLy9JxQSBsSOT2bx 61NWUt5T/Xsi0ECYZM4YvsNpUP6XrpSTyG3c8T3fY9vXYLNKZBv1ht6OODpLeuke DxULAWP+DdzUS8a3qfKQvIJzSTloU31a1MBG58DWNJ072EQfa2YNaVE75VQk/z5/ 0xZbSHdPY/0Xgx8ltpKu37bSO676JiVQZZ1HEAuti4h21+USYueYD2L8/Bx4k9e/ 4UaOcw3MaCDHP/sf5hg17kQBjhhS0lV9Zv6H9QbHZUocJTJlIU+vXtgkQlrfi3n8 8j5m+ywVarmLtPqg1j2rqcw7LBCPe0qRXH3e5X/YmNMc3rH9bQz4cTo8ZSN9r8zS c17zGbbAqlGsBkpFAbQz =DGPb -----END PGP SIGNATURE----- Merge tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.12 kernel cycle.
