All currently known models using the tps68470 PMIC have a privacy LED for the back sensor (first ACPI consumer dev of the PMIC) connected to the ileda output of the PMIC. Add a LED lookup table entry for this, so that the v4l2-core code turns on the LED when streaming from the sensor. Signed-off-by: Hans de Goede <hdegoede@redhat.com> --- Kate, please include this in the v2 series adding the leds-tps68470 driver. --- drivers/platform/x86/intel/int3472/tps68470.c | 28 ++++++++++++++++++- 1 file changed, 27 insertions(+), 1 deletion(-)
