TPS2549: TPS2549IRTERQ1 : Linux Driver

Part Number: TPS2549
Other Parts Discussed in Thread: TPS65217

Hi Ti,

TPS2549IRTERQ1 OS Linux compatible ?

We have latest linux-imx source from source.codeaurora.org, Do we need to add any specific driver to use the TPS2549IRTERQ1 with this source.

Can we get this driver from anywhere ?

Thank you!

    Hello,

    As long as the TPS2549 is powered, enabled, and configured through the control pins, we will advertise a charging mode. I am not sure what you are referring to with drivers.

    Thanks,

    Hi 

    As TPS65217 Power Management IC (PMIC) with switch mode charger has following driver files to use with linux-imx.

    • ./drivers/power/supply/tps65217_charger.c
    • ./drivers/regulator/tps65217-regulator.c
    • ./drivers/mfd/tps65217.c
    • ./drivers/video/backlight/tps65217_bl.c
    • ./Documentation/devicetree/bindings/power/supply/tps65217_charger.txt
    • ./Documentation/devicetree/bindings/leds/backlight/tps65217-backlight.txt
    • ./Documentation/devicetree/bindings/regulator/tps65217.txt
    • ./arch/arm/boot/dts/tps65217.dtsi
    • ./include/linux/mfd/tps65217.

    Is there any driver files for TPS2549 similar to TPS65217 ?

    Regards,

    Hello Saurabh,

    The TPS2549 does not need to be programmed. The different charging modes are selected by changing the analog signals on the CTL pins. Please take a look at the TPS2549 datasheet. It is a USB charging port controller with power switch, and is not comparable to the TPS65217, which is a PMIC.

    Thanks,

    Emma
