Hello, I've noticed that the voltage check in regulator_is_supported_voltage() function was inverted, what resulted in strange side effects. One of such side effects appeared in sdhci driver, which has some build-in support for special case of fixed regulators. Now, after fixing regulator_is_supported_voltage(), the sdhci driver stopped working with fixed regulators. The provided patch series fixes regulator_is_supported_voltage() function and updates sdhci driver to correctly operate with fixed voltage regulators. The second patch unifies handling of fixed regulators and regulators with disabled voltage change due to their constraints. This restores support for such regulators in sdhci driver (such case is present on Samsung GONI board). If possible, I would recomment to push those patches to v3.7-rc series.
