2019-04-05drivers: gpio: janz-ttl: use devm_platform_ioremap_resource()Enrico Weigelt, metux IT consult1-3/+1
Use the new helper that wraps the calls to platform_get_resource() and devm_ioremap_resource() together. Signed-off-by: Enrico Weigelt, metux IT consult <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2018-03-19gpio: janz-ttl: Use BIT() macroLinus Walleij1-6/+7
This makes the code more readable by using the BIT() macro. Signed-off-by: Linus Walleij <[email protected]>
2018-03-19gpio: janz-ttl: Include the right headerLinus Walleij1-1/+1
This driver is a pure GPIO driver and should only include <linux/gpio/driver.h>. Signed-off-by: Linus Walleij <[email protected]>
2016-02-23gpio: janz-ttl: Use devm_gpiochip_add_data() for gpio registrationLaxman Dewangan1-11/+1
Use devm_gpiochip_add_data() for GPIO registration and remove the need of driver callback .remove. Signed-off-by: Laxman Dewangan <[email protected]>
2016-01-05gpio: convert remaining users to gpiochip_add_data()Linus Walleij1-1/+1
For completion, sweep the floor from all gpiochip_add() usage so we can remove that function and get rid of the function wrapper gpiochip_add(). Signed-off-by: Linus Walleij <[email protected]>
2015-12-26gpio: janz-ttl: Be sure to clamp return valueLinus Walleij1-1/+1
As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Cc: Ira W. Snyder <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2015-11-19gpio: change member .dev to .parentLinus Walleij1-3/+3
The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

2014-10-20gpio: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <[email protected]>

2014-05-09gpio: janz-ttl: remove unnecessary OOM messagesJingoo Han1-1/+0
The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2012-01-02gpio: Convert GPIO drivers to module_platform_driverMark Brown1-12/+1

2011-12-12gpiolib: output basic details and consolidate gpio device driversGrant Likely1-2/+0
This patch adds a kernel message, containing GPIO range and device name on successful device registration, and removes duplicate messages from the following drivers: * gpio-adp5588 * gpio-bt8xx * gpio-cs5535 * gpio-janz-ttl * gpio-nomadik * gpio-pcf857x * gpio-xilinx * drivers/of/gpio.c Signed-off-by: Hartmut Knaack <[email protected]> [[email protected]: squashed 2 patches together] Signed-off-by: Grant Likely <[email protected]>
2011-06-06gpio: reorganize driversGrant Likely1-0/+258
