+static void exynos4_mipi_phy_control(unsigned int enable,

Please reorder parameters, dev_index should be first parameter.
+{
- struct exynos4_power *pmu =
- (struct exynos4_power *)samsung_get_base_power();
- unsigned int addr, cfg = 0;
- if (dev_index < 1)
I think dev_index == 0 is better.
- addr = (unsigned int)&pmu->mipi_phy0_control;

- addr = (unsigned int)&pmu->mipi_phy1_control;
- cfg = readl(addr);
