Hi Ti,

TUSB4020BIPHPQ1 OS Linux compatible ?

No Special Driver Requirements; Works Seamlessly on any Operating System With USB Stack Support.

It is some standard driver? It's somewhere downloadable if what?

We have latest linux-imx source from source.codeaurora.org, Do we need to add any specific driver to use the TUSB4020BIPHPQ1 with this source.

Thank you!

"Works Seamlessly on any Operating System With USB Stack Support" means exactly that; the USB hub driver is already built in.

Hello Saurabh,

No special drivers are needed for the TPS2549 device either. The operating system does not directly control the TPS2549 device.

Hi JMMN

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 ?

How does the TPS2549 is controlled ?

Regards,

Saurabh

Hi Saurabh,

The TPS65217 is a PMIC that requires more control than a TPS2549 charging port controller. What are you looking to implement?

I am moving your question over to the correct forum that supports these devices.

Hi Saurabh,

Please open a new thread on the TPS2549, as it is in a different device family.

Thanks,

Emma
