leds: pca955x: Switch to i2c probe_new

2021-08-20T09:00:08+00:00

The deprecated i2c probe functionality doesn't work with OF compatible strings, as it only checks for the i2c device id. Switch to the new way of probing and grab the match data to select the chip type. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: pca955x: Let the core process the fwnode

2021-08-20T09:00:08+00:00

Much of the fwnode processing in the PCA955x driver is now in the LEDs core driver, so pass the fwnode in the init data when registering the LED device. In order to preserve the existing naming scheme, check for an empty name and set it to the LED number. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: pca955x: Implement the default-state property

2021-08-20T09:00:07+00:00

In order to retain the LED state after a system reboot, check the documented default-state device tree property during initialization. Modify the behavior of the probe according to the property. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: pca955x: Add brightness_get function

2021-08-20T09:00:07+00:00

Add a function to fetch the state of the hardware LED. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: pca955x: Clean up code formatting

2021-08-20T09:00:06+00:00

Format the code. Add some variables to help shorten lines. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: leds-core: Implement the retain-state-shutdown property

2021-08-20T09:00:06+00:00

Read the retain-state-shutdown device tree property to set the existing LED_RETAIN_AT_SHUTDOWN flag. Then check the flag when unregistering, and if set, don't set the brightness to OFF. This is useful for systems that want to keep the HW state of the LED across reboots. Signed-off-by: Eddie James Signed-off-by: Pavel Machek

leds: trigger: remove reference to obsolete CONFIG_IDE_GD_ATA

2021-08-18T06:59:47+00:00

Commit b7fb14d3ac63 ("ide: remove the legacy ide driver") removes the definition of the config IDE_GD_ATA. So, remove the obsolete reference in ./drivers/leds/trigger/Kconfig. Signed-off-by: Lukas Bulwahn Signed-off-by: Pavel Machek

leds: lp50xx: Fix chip name in KConfig

2021-08-18T06:58:21+00:00

The 9-channel one is called LP5009, not LP509. Signed-off-by: Jan Kundrát Reviewed-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: pwm: add support for default-state device property

2021-08-18T06:27:31+00:00

This patch adds support for "default-state" devicetree property, which allows to defer pwm init to first use of led. This allows to configure the PWM early in bootloader to let the LED blink until an application in Linux userspace sets something different.

leds: move default_state read from fwnode to core

2021-08-18T06:27:30+00:00

This patch introduces a new function to read initial default_state from fwnode. Suggested-by: Pavel Machek Signed-off-by: Denis Osterland-Heim Signed-off-by: Pavel Machek
