From 2c5b2cccdbde278fb702893404a2ea20f81f0345 Mon Sep 17 00:00:00 2001 From: Mark Yao Date: Mon, 30 Nov 2015 18:33:40 +0800 Subject: drm: bridge/dw_hdmi: add atomic API support Fill atomic needed funcs with default atomic helper library. Rockchip use dw_hdmi, and drm/rockchip will covert to atomic api, we need dw_hdmi support atomic funcs. Now another drm driver use dw_hdmi is imx, not yet atomic, so check DRIVER_ATOMIC at runtime to spilt atomic and not atomic.
