| Subject: ARM: pxa: add regulator_has_full_constraints to poodle board file |
| |
| From: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> |
| |
| commit 9bc78f32c2e430aebf6def965b316aa95e37a20c upstream. |
| |
| Add regulator_has_full_constraints() call to poodle board file to let |
| regulator core know that we do not have any additional regulators left. |
| This lets it substitute unprovided regulators with dummy ones. |
| |
| This fixes the following warnings that can be seen on poodle if |
| regulators are enabled: |
| |
| ads7846 spi1.0: unable to get regulator: -517 |
| spi spi1.0: Driver ads7846 requests probe deferral |
| wm8731 0-001b: Failed to get supply 'AVDD': -517 |
| wm8731 0-001b: Failed to request supplies: -517 |
| wm8731 0-001b: ASoC: failed to probe component -517 |
