Well, I needed it when bringing up the board ;) - to validate the supplies, clocks, etc. Right, this function should be embraced within a #ifdef CONFIG_PALSMAS_AUDPWR and not compile in the general case (my code calling it is #ifdef-ed anyway). > >> >> Signed-off-by: Lubomir Popov <lpopov@mm-sol.com> >> --- >> V2 aligns to changed PMIC name (and file names accordingly) >> from twl6035 to Palmas and is based on current u-boot-ti >> master.

Right, and you need u-boot modified to do validation? I think either such code should stay out of tree, or be validated by expicit i2c commands (which already is supported) OR tested by virtual regulator consumer in linux ;) I dont think we should make u-boot an OS. just my 2 cents. my rule of thumb is: if it is not needed for boot, do it elsewhere other than bootloader.

Yes, TI has omapboot, just a bootloader. I think that U-Boot, on the other hand, has become a quite powerfull tool, with a lot of useful functionality, at least for me as a hardware guy. But of course, if the community thinks of it as of a bootloader only, I give up. ;) > Regards, > NM > Best regards, Lubo

But of course, if the community thinks of it as of a > bootloader only, I give up. ;) Lets not forget it is a bootloader. there are gazillion options - barebox, uboot, vendor specific ones like omapboot etc. U-boot is primarily a bootloader. It provides excellent testing interfaces which are useful for preliminary testing. However stuff like Audio power chip LDO supply enable when not really used, makes no real sense in my opinion. Sure you can use u-boot to validate with the i2c commands available - hell, you can even write your own uEnv.txt or bootcmd which will do a bunch of validation at boot.. but why have it in mainline u-boot is beyond me.
