GLSDK PMIC source code

Other Parts Discussed in Thread: TPS65910, TPS65917-Q1

Hello,

I'm using GLSDKv7.00.00.04. I'd like to see a source code of TPS659039 (TPS65917) to understand PMIC initialization. But I can't find it in u-boot. Whereas I can see some sources of other PMIC devices.

e.g.) pmic_tps65910.c, pmic_tps659217.c, and pmic_tps659218.c
/ti-glsdk_dra7xx-evm_7_00_00_04/board-support/u-boot/drivers/power/pmic

I think the functions in these sources above are called below.

/ti-glsdk_dra7xx-evm_7_00_00_04/board-support/u-boot/board/ti/am335x/board.c
/ti-glsdk_dra7xx-evm_7_00_00_04/board-support/u-boot/board/ti/am43xx/board.c

Could you give me some advice?

Regards,
Kazu

Hello Kazu,

Definitions for TPS65903x you can find in:
/u-boot_main_line/u-boot/drivers/power/palmas.c
/u-boot/arch/arm/cpu/armv7/omap5/hw_data.c
/arch/arm/include/asm/arch-omap5/clock.h

If you want to add more functionality to PMIC (TPS659039) you can add your modifications in Palmas driver.

See the patch for mail-line u-boot - lists.denx.de/.../155864.html
Take a look on TI's u-boot:
gitorious.org/.../27fd06b355442963cafd993cb28396a6cc2e87ad

Best regards,
Yanko

Hello Yanko,

Thank you for your quick reply. I was able to see the descriptions about TPS65903X and TPS659038. How about TPS65917? I think this PMIC is used on DRA72x J6 ECO EVM. I seem that GLSDK u-boot as J6 ECO EVM uses the control code for TPS659038. What do you think?

Regards,
Kazu

Kazu,

The companion power management IC (PMIC) for J6Eco EVM is TPS65917-Q1.
The TPS659038 and TPS65917 are software-compatible, use common structures.

Best regards,
Yanko
