[PATCH v3 1/5] rockchip: io-domain: Add debug logging for regulators during probe

[Justin Klaassen]

Log the value of the regulators during initialization of the IO-domain
driver to aid in debugging GPIO voltage configuration problems.

Signed-off-by: Justin Klaassen <justin at tidylabs.net>

Changes in v3:
- Use dev_dbg instead of log_debug

Changes in v2:
- Made added IO-domain driver logs verbose and consistent
