drm/mediatek: separate color module to fixup error memory reallocation

2017-06-27T09:34:53Z

Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different hardware settings) calls devm_kfree() and then devm_kzalloc() to reallocate color module data structure. But this reallocation cannnot guarantee the new address is unchanged, but the caller will use the old address, which is wrong. Fix it by separate color module from general components, this patch separate color module to independent files, like mtk_disp_ovl.c and mtk_disp_rdma.c do Fixes: c5f228ef6ccd ("drm/mediatek: add *driver_data for different hardware settings") Signed-off-by: YT Shen Tested-by: Bibby Hsieh Signed-off-by: CK Hu

drm/mediatek: add shadow register support

2017-04-07T16:02:13Z

We need to acquire mutex before using the resources, and need to release it after finished. So we don't need to write registers in the blanking period. Signed-off-by: YT Shen Acked-by: CK Hu

drm/mediatek: add *driver_data for different hardware settings

2017-04-07T16:02:12Z

There are some hardware settings changed, between MT8173 & MT2701: DISP_OVL address offset changed, color format definition changed. DISP_RDMA fifo size changed. DISP_COLOR offset changed. MIPI_TX pll setting changed. And add prefix for mtk_ddp_main & mtk_ddp_ext & mutex_mod. Signed-off-by: YT Shen Acked-by: CK Hu

drm: mediatek: use crtc helper drm_crtc_from_index()

2017-01-18T14:21:06Z

Use drm_crtc_from_index() to find drm_crtc for given index, so that we do not need to maintain a pointer array in struct mtk_drm_private.

drm/mediatek: Add DSI sub driver

2016-05-06T15:47:37Z

This patch add a drm encoder/connector driver for the MIPI DSI function block of the Mediatek display subsystem and a phy driver for the MIPI TX D-PHY control module. Signed-off-by: Jitao Shi Signed-off-by: Philipp Zabel

drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.

2016-05-06T15:47:35Z

This patch adds an initial DRM driver for the Mediatek MT8173 DISP subsystem. It currently supports two fixed output streams from the OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
