The patch series adds definitions for GPIO line directions. For occasional GPIO contributor like me it is always a pain to remember whether 1 or 0 was used for GPIO direction INPUT/OUTPUT. Judging the fact that I removed few comments like: /* Return 0 if output, 1 if input */ /* This means "out" */ return 1; /* input */ return 0; /* output */ it seems at least some others may find it hard to remember too. Adding defines for these values helps us who really have good - but short duration - memory :] This idea comes from RFC series for ROHM BD71828 PMIC and was initially discussed with Linus Walleij here: https://lore.kernel.org/lkml/c06725c3dd34118a324907137758d8b85b3d4043.camel@xxxxxxxxxxxxxxxxx/ but as this has no dependencies to BD71828 work (which probably takes a while) I decided to make it independent series. Patches are compile-tested only. I have no HW to really test them. Thus I'd appreciate carefull review. This work is mainly about converting zeros and ones to the new defines but it wouldn't be first time I get it wrong. Changelog v2: - squashed patches 2-61 into patch 2. - dropped patch 62 (can be applied later) - rebased (cherry-picked) changes on top of GPIO devel branch. Patch 1: - adds the defines Patch 2: - convert drivers to use new defines This patch series is based on GPIO tree devel branch. --- Matti Vaittinen (2): gpio: Add definition for GPIO direction gpio: Use new GPIO_LINE_DIRECTION drivers/gpio/gpio-104-dio-48e.c | 5 ++++- drivers/gpio/gpio-104-idi-48.c | 2 +- drivers/gpio/gpio-104-idio-16.c | 4 ++-- drivers/gpio/gpio-74xx-mmio.c | 5 ++++- drivers/gpio/gpio-amd-fch.c | 2 +- drivers/gpio/gpio-aspeed.c | 7 +++---- drivers/gpio/gpio-bcm-kona.c | 6 +++--- drivers/gpio/gpio-bd70528.c | 8 +++++--- drivers/gpio/gpio-bd9571mwv.c | 4 +++- drivers/gpio/gpio-dln2.c | 6 +++--- drivers/gpio/gpio-exar.c | 5 ++++- drivers/gpio/gpio-f7188x.c | 5 ++++- drivers/gpio/gpio-gpio-mm.c | 5 ++++- drivers/gpio/gpio-htc-egpio.c | 5 ++++- drivers/gpio/gpio-ich.c | 5 ++++- drivers/gpio/gpio-kempld.c | 5 ++++- drivers/gpio/gpio-lp873x.c | 2 +- drivers/gpio/gpio-lp87565.c | 5 ++++- drivers/gpio/gpio-madera.c | 5 ++++- drivers/gpio/gpio-max3191x.c | 2 +- drivers/gpio/gpio-merrifield.c | 5 ++++- drivers/gpio/gpio-mmio.c | 21 +++++++++++++++------ drivers/gpio/gpio-mockup.c | 11 +++-------- drivers/gpio/gpio-moxtet.c | 4 ++-- drivers/gpio/gpio-mvebu.c | 5 ++++- drivers/gpio/gpio-mxs.c | 5 ++++- drivers/gpio/gpio-omap.c | 6 ++++-- drivers/gpio/gpio-pca953x.c | 5 ++++- drivers/gpio/gpio-pci-idio-16.c | 4 ++-- drivers/gpio/gpio-pcie-idio-24.c | 9 ++++++--- drivers/gpio/gpio-pisosr.c | 2 +- drivers/gpio/gpio-pl061.c | 5 ++++- drivers/gpio/gpio-raspberrypi-exp.c | 5 ++++- drivers/gpio/gpio-rcar.c | 5 ++++- drivers/gpio/gpio-reg.c | 3 ++- drivers/gpio/gpio-sa1100.c | 5 ++++- drivers/gpio/gpio-sama5d2-piobu.c | 7 ++++--- drivers/gpio/gpio-sch.c | 5 ++++- drivers/gpio/gpio-sch311x.c | 5 ++++- drivers/gpio/gpio-siox.c | 4 ++-- drivers/gpio/gpio-stmpe.c | 5 ++++- drivers/gpio/gpio-tc3589x.c | 5 ++++- drivers/gpio/gpio-tegra.c | 5 ++++- drivers/gpio/gpio-tegra186.c | 4 ++-- drivers/gpio/gpio-thunderx.c | 5 ++++- drivers/gpio/gpio-tpic2810.c | 2 +- drivers/gpio/gpio-tps65086.c | 2 +- drivers/gpio/gpio-tps65912.c | 4 ++-- drivers/gpio/gpio-tps68470.c | 6 +++--- drivers/gpio/gpio-tqmx86.c | 5 ++++- drivers/gpio/gpio-ts4900.c | 5 ++++- drivers/gpio/gpio-twl4030.c | 10 +++++----- drivers/gpio/gpio-twl6040.c | 3 +-- drivers/gpio/gpio-uniphier.c | 5 ++++- drivers/gpio/gpio-wcove.c | 7 +++++-- drivers/gpio/gpio-ws16c48.c | 5 ++++- drivers/gpio/gpio-xgene.c | 5 ++++- drivers/gpio/gpio-xra1403.c | 5 ++++- drivers/gpio/gpio-xtensa.c | 4 ++-- drivers/gpio/gpio-zynq.c | 7 +++++-- include/linux/gpio/driver.h | 3 +++ 61 files changed, 214 insertions(+), 102 deletions(-) -- 2.21.0 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
