2013-12-12gpio: 74x164: Remove non-DT supportAlexander Shiyan1-13/+1
Commit 20bc4d5d565159eb2b942bf4b7fae86fba94e32c (gpio: 74x164: Add support for the daisy-chaining) introduce check for DT for the driver, so driver cannot be used without DT. There are no in-tree users of this driver, so remove non-DT support completely.

2013-12-04gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij1-1/+1
This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-09-23gpio: gpio-74x164: Remove redundant of_match_ptrSachin Kamat1-1/+1
'gen_74x164_dt_ids' is always compiled in. Hence the macro is not necessary. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-08-16gpio: use dev_get_platdata()Jingoo Han1-1/+1
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-03-27gpio: 74x164: use spi_get_drvdata() and spi_set_drvdata()Jingoo Han1-4/+4
Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-10-16gpio-74x164: Fix buffer allocation sizeRoland Stigge1-1/+1
The new registers handling in the gpio-74x164 driver allocates chip->registers * 8 bytes where only one byte per register is necessary. This patch fixes this. Signed-off-by: Roland Stigge <stigge@antcom.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-09-12gpio: 74x164: Add support for the daisy-chainingMaxime Ripard1-7/+61
The shift registers have an output pin that, when enabled, propagates the values of its internal register to the pins. If another value comes to the register while the output pin is disabled, this new value will makae the older shift into the next register in the chain. This patch adds support for daisy-chaining the registers, using the regular SPI chip select mechanism to manage the output pin, and the registers-number dt property to set the number of chained registers.

2011-11-01drivers/gpio: Fix drivers who are implicit users of module.hPaul Gortmaker1-0/+1
A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in gpio are actually calling out for <module.h> explicitly in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-06-13gpio/74x164: fix clash with gpiolib namespaceLinus Walleij1-3/+3
The 74x164 GPIO driver has a static inline helper called gpio_to_chip which clashes with the gpiolib namespace if we try to expose the function with the same name from gpiolib, and it's still confusing even if we don't do that. So rename it to gpio_to_74x164_chip().
