* gpu: ipu-v3: add support for separate alpha channelsPhilipp Zabel2017-03-151-0/+22
| | | | | | | | | The IPUv3 can read 8-bit alpha values from a separate IDMAC channel driven by the Alpha Transparency Controller (ATC) for the graphics IDMAC channels. This allows to reduce memory bandwidth via a conditional read mechanism or to support planar YUV formats with alpha transparency. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
* gpu: ipu-v3: add unsynchronised DP channel disablingPhilipp Zabel2017-03-151-1/+1
| | | | | | | | | | | When disabling the foreground DP channel during a modeset, the DC is already disabled without waiting for end of frame. There is no reason to wait for a frame boundary before updating the DP registers in that case. Add support to apply updates immediately. No functional changes, yet.

* gpu: ipu-v3: Add FSU channel linking supportSteve Longerbeam2016-08-291-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds functions to link and unlink source channels to sink channels in the FSU: int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch); int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch); The channels numbers are usually IDMAC channels, but they can also be channels that do not transfer data to or from memory. The following convenience functions can be used in place of ipu_fsu_link/unlink() when both source and sink channels are IDMAC channels: int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink); int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink); So far the following links are supported: IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC PUV3_CHANNEL_IC_PRP_VF_MEM -> IPUV3_CHANNEL_MEM_ROT_VF IPUV3_CHANNEL_IC_PP_MEM -> IPUV3_CHANNEL_MEM_ROT_PP IPUV3_CHANNEL_CSI_DIRECT -> IPUV3_CHANNEL_CSI_VDI_PREV More links can be added to the fsu_link_info[] array.

* gpu: ipu-v3: ipu-dmfc: Use static DMFC FIFO allocation mechanismLiu Ying2016-07-121-3/+0
| | | | | | | | | | | | For all video modes we support currently, we always get 2 slots for a plane by using the current existing dynamic DMFC FIFO allocation mechanism. So, let's change to use the static one to simplify the code. This also makes it easier to implement the atomic mode setting as we don't need to handle allocation failure cases then.

* drm/imx: Match imx-ipuv3-crtc components using device node in platform dataPhilipp Zabel2016-05-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The component master driver imx-drm-core matches component devices using their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during probing. Before that, of_node was set and caused an of: modalias to be used instead of the platform: modalias, which broke module autoloading. On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc probe function calls component_add, component matching in imx-drm-core fails. While dev->of_node will be set once the next component tries to bring up the component master, imx-drm-core component binding will never succeed if one of the crtc devices is probed last. Add of_node to the component platform data and match against the pdata->of_node instead of dev->of_node in imx-drm-core to work around this problem.

The function ipu_di_adjust_videomode() aims to fix these issues by adjusting a passed videomode to IPU restrictions. The function can be called from the drm_crtc_helper_funcs->mode_fixup() methods.

Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.
