    OMAP: DSS2: Delay regulator_get() calls · 5f42f2ce
    Tomi Valkeinen authored
    DSS submodules DPI/SDI/DSI/VENC require a regulator to function.
    However, if the board doesn't use, say, SDI, the board shouldn't need to
    configure vdds_sdi regulator required by the SDI module.
    Currently the regulators are acquired when the DSS driver is loaded.
    This means that if the kernel is configured with SDI, vdds_sdi regulator
    is needed for all boards.
    This patch changes the DSS driver to acquire the regulators only when a
    display of particular type is initialized. For example, vdds_sdi is
    acquired when sdi_init_display() is called.
