| * The BUCK10 on BD72720 has two modes of operation, depending on a LDON_HEAD |
| * setting. When LDON_HEAD is 0x0, the behaviour is as with other bucks, eg. |
| * voltage can be set to a values indicated below using the VSEL register. |
| * |
| * However, when LDON_HEAD is set to 0x1 ... 0x7, BUCK 10 voltage is, according |
| * to the data-sheet, "automatically adjusted following LDON_HEAD setting and |
| * clamped to BUCK10_VID setting". |
| * |
| * Again, reading the data-sheet shows a "typical connection" where the BUCK10 |
| * is used to supply the LDOs 1-4. My assumption is that in practice, this |
| * means that the BUCK10 voltage will be adjusted based on the maximum output |
| * of the LDO 1-4 (to minimize power loss). This makes sense. |
| * |
| * Auto-adjusting regulators aren't something I really like to model in the |
| * driver though - and, if the auto-adjustment works as intended, then there |
| * should really be no need to software to care about the buck10 voltages. |
| * If enable/disable control is still needed, we can implement buck10 as a |
| * regulator with only the enable/disable ops - and device-tree can be used |
| * to model the supply-relations. I believe this could allow the regulator |
| * framework to automagically disable the BUCK10 if all LDOs that are being |
| * supplied by it are disabled. |
