v8->v9:
 * Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository.
 * To address Philipp's comment, mention that a common compatible string
   "snps,dw-mipi-dsi" should be appended.
 * To address Philipp's comment, add a new required clock pclk and clean up
   clock-names.

v7->v8:
 * None.

v6->v7:
 * None.

v5->v6:
 * None.

v3->v4:
 * None.

v2->v3:
 * As suggested by Phillip Zabel, change the clocks and the clock-names
   properties to use the pllref and core_cfg clocks only.

v1->v2:
 * None.
