drm/tinydrm/mi0283qt: Let the display pipe handle power

2018-01-15T14:16:06Z

It's better to leave power handling and controller init to the modesetting machinery using the simple pipe .enable and .disable callbacks. Remove unused mipi_dbi_pipe_enable().

drm/tinydrm: Drop driver registered message

2017-09-16T12:07:59Z

No need to put out a driver registered message since drm_dev_register() does that now. SPI speed is an important metric when dealing with display problems, so retain that info.

This removes the call to mipi_dbi_init() from mipi_dbi_spi_init() so that drivers can have a driver-specific implementation if needed.
