Hi,
v2 of this series merges the AXP717 support patches in, as they didn't make it into the tree yet. As there is little point in creating a separate AXP717 SPL driver file, just to delete it again two patches later, this series skips the separate file altogether. I put in the related AXP717 U-Boot proper driver here. The code itself is mostly unchanged from v1, it's just a rebase and re-arrangement of the patches.
========================= This is the first series in an attempt to clean up the X-Powers AXP PMIC drivers used by the SPL for sunxi boards. So far we have a separate driver file for each AXP variant, but the code was largely the same, just differing by the regulator ranges.
This adds a new generic driver, which reads the regulator description from an array of structs. This is similar to how the DM AXP driver used for U-Boot proper works, but is simplified, since we won't need the full feature set for the SPL, and we want to keep the code size small.
To help bisect-ability, and to simplify review, each of the simpler AXP drivers covered by this approach is handled in a separate patch.
We just add the AXP717 support first, then convert over the AXP313 and AXP305. The other AXP SPL drivers are more complex, and support more regulators, but my hunch is that we really just need the DC/DC converters in the SPL. However I need to prove and test this, so I will convert the other AXP chips later.
Please have a look and comment whether the approach in general is a good idea.
Cheers, Andre
