treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

fbdev: via: use new GPIO line value setter callbacks

2025-05-31T08:24:01+00:00

struct gpio_chip now has callbacks for setting line values that return an integer, allowing to indicate failures. Convert the driver to using them. Signed-off-by: Bartosz Golaszewski Reviewed-by: Linus Walleij Signed-off-by: Helge Deller

fbdev: Switch back to struct platform_driver::remove()

2024-10-08T19:47:18+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files. Signed-off-by: Uwe Kleine-König Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: viafb: Make I2C terminology more inclusive

2024-07-11T10:07:48+00:00

I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave" with more appropriate terms. Inspired by Wolfram's series to fix drivers/i2c/, fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists in the specification.

There are some actions with value 'tmp' but 'dst_addr' is checked instead. It is obvious that a copy-paste error was made here and the value of variable 'tmp' should be checked here.

fbdev: remove I2C_CLASS_DDC support

2024-01-18T20:10:41+00:00

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC. Class-based device auto-detection is a legacy mechanism and shouldn't be used in new code. So we can remove this class completely now.
