| 2022-01-12 | leds: tca6507: Get rid of duplicate of_node assignment | Andy Shevchenko | 1 | -3/+0 | |
| GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove assignment here. For the details one may look into the of_gpio_dev_init() implementation. Call graph: --> tca6507_probe_gpios() --> gpiochip_add_data() --> gpiochip_add_data_with_key() --> of_gpio_dev_init() Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Pavel Machek <pavel@ucw.cz> | |||||

| 2018-06-13 | treewide: devm_kzalloc() -> devm_kcalloc() | Kees Cook | 1 | -2/+2 | |
| The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

| 2015-11-19 | gpio: change member .dev to .parent | Linus Walleij | 1 | -1/+1 | |
| 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.

| 2015-08-28 | leds: Export OF module alias information in missing drivers | Javier Martinez Canillas | 1 | -0/+1 | |
| The I2C core always reports the MODALIAS uevent as "i2c:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: I2C id table or OF match table). So drivers needs to export the I2C id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and I2C id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same I2C device name for example. To avoid the above, the I2C core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes.

The array maybe be sparsely filled but it is indexed by device address so we must at least allocate as many slots as the highest address used. It is easiest just to allocate all 7. 2/ range check the 'reg' value properly. 3/ led.flags must be initialised to zero, else all leds could be treated as GPIOs (depending on what happens to be on the stack).

| Just a small tidy-up. 1) There is a NULL dereference if the tca allocation fails. 2) The call to cancel_work_sync() isn't needed because we haven't scheduled any work. 3) The call to i2c_set_clientdata() isn't needed because the core handles that automatically if probe() fails. 4) I added some curly braces for style reasons.

| TI's TCA6507 is the LED driver in the GTA04 Openmoko motherboard. The driver provides full support for brightness levels and hardware blinking. This driver can drive each of 7 outputs as an LED or a GPIO output, and provides hardware-assist blinking.
