TPS65073 and OMAP PSP power management

Other Parts Discussed in Thread: TPS65073

Hi,

 

somehow I cannot find anymore the PSP internal community list anymore. If someone could point me to it, that would be great. In the meanwhile I thought I post here.

Could someone comment on how the TPS65073 PMIC is supported in the OMAP3 PSP wrt power management. I know there have been some variances of the power board for the OMAP3 EVM and I needed to know if we have tested a power board with the TPS65073 and the PSP power management functionality. Any gotchas or things to watch out for.

 

Thanks,

--Gunter

    Hi Gunter,

    I am not sure about any  PSP forum, however you can try this question on the PMU forum - https://e2e.ti.com/support/power_management/pmu/int-_pmu/f/202.aspx

    There are TPS65073 question son that site. You can also try the OMAP applications forum, some one can help with this. I know there are folks on that forum who have used OMAP3+TPS65073 -https://e2e.ti.com/support/arm174_microprocessors/omap_applications_processors/int-omap/default.aspx

     

    Regards,

    Gunter,

    i have connected a TPS65073 module successfully to the OMAP3EVM.  I only did basic boot up of the board, but i know PSP team did some rudimentary testing with that module.  Support for it can be found in the git tree or you can configure the kernel from PSP for 65073 support.

    Gunter,

    Basic driver for TPS65073 device, complying with the Linux Voltage Regulator Framework, is a part of OMAP-PSP release. This driver has been tested on OMAP3 EVM for basic power-management related functionality. The driver can be found at: drivers/regulator/tps6507x-regulator.c in the release package.

    However, this driver is currently not used for voltage upscaling/downscaling in the system.
