leds: flash: Use fwnode_get_next_child_node() instead

2025-10-21T09:46:22+00:00

fwnode_get_next_child_node() is now the same as fwnode_get_next_available_child_node() on all backends (OF, ACPI and swnode). In order to remove the available variants, switch the uses to non-available variants (device_get_next_child_node() in this case).

leds: flash: leds-qcom-flash: Add a separate register map for PMI8998

2025-08-18T08:49:12+00:00

The 3-channel flash module in PMI8998 has several registers different than the others, such as: torch_clamp. Add different register fields for it.

leds: flash: leds-qcom-flash: Update torch current clamp setting

2025-08-18T08:49:11+00:00

There is a register to clamp the flash current per LED channel when safety timer is disabled. It needs to be updated according to the maximum torch LED current setting to ensure the torch current won't be clamped unexpectedly.

leds: tps6131x: Add V4L2_FLASH_LED_CLASS dependency

2025-07-01T13:26:03+00:00

This driver can optionally use the v4l2_flash infrastructure, but fails to link built=in if that is in a loadable module: ld.lld-21: error: undefined symbol: v4l2_flash_release >>> referenced by leds-tps6131x.c:792 (drivers/leds/flash/leds-tps6131x.c:792) Add the usual Kconfig dependency for it, still allowing it to be built when CONFIG_V4L2_FLASH_LED_CLASS is disabled.

leds: flash: leds-qcom-flash: Fix registry access after re-bind

2025-06-13T13:41:34+00:00

Driver in probe() updates each of 'reg_field' with 'reg_base': for (i = 0; i < REG_MAX_COUNT; i++) regs[i].reg += reg_base; 'reg_field' array (under variable 'regs' above) is statically allocated, thus each re-bind would add another 'reg_base' leading to bogus register addresses. Constify the local 'reg_field' array and duplicate it in probe to solve this.

leds: tps6131x: Add support for Texas Instruments TPS6131X flash LED driver

2025-05-22T08:24:51+00:00

The TPS61310/TPS61311 is a flash LED driver with I2C interface. Its power stage is capable of supplying a maximum total current of roughly 1500mA. The TPS6131x provides three constant-current sinks, capable of sinking up to 2 x 400mA (LED1 and LED3) and 800mA (LED2) in flash mode. In torch mode each sink (LED1, LED2, LED3) supports currents up to 175mA.

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
