commit 3d1f62c686acdedf5ed9642b763f3808d6a47d1e upstream. The saturation bit was being set at bit 9 in the second 32-bit word of the TPMEM CSC.

2019-02-12gpu: ipu-v3: image-convert: Prevent race between run and unprepareSteve Longerbeam1-3/+7
[ Upstream commit 819bec35c8c9706185498c9222bd244e0781ad35 ] Prevent possible race by parallel threads between ipu_image_convert_run() and ipu_image_convert_unprepare(). This involves setting ctx->aborting to true unconditionally so that no new job runs can be queued during unprepare, and holding the ctx->aborting flag until the context is freed. Note that the "normal" ipu_image_convert_abort() case (e.g. not during context unprepare) should clear the ctx->aborting flag after aborting any active run and clearing the context's pending queue. This is because it should be possible to continue to use the conversion context and queue more runs after an abort.

[ Upstream commit b7dfee2433576f1f030cb84cdb04b70f36554992 ] The description of the CSI_SEL bit in the i.MX6 reference manual is incorrect. It states "This bit defines which CSI is the input to the IC. This bit is effective only if IC_INPUT is bit cleared". From experiment it was found this is in fact not correct. The CSI_SEL bit selects which CSI is input to _both_ the VDIC _and_ the IC. If the IC_INPUT bit is set so that the IC is receiving from the VDIC, the IC ignores the CSI_SEL bit, but CSI_SEL still selects which CSI the VDIC receives from in that case.

2016-09-19gpu: ipu-v3: Add queued image conversion supportSteve Longerbeam4-1/+1725
This patch implements image conversion support using the IC tasks, with tiling to support scaling to and from images up to 4096x4096. Image rotation is also supported. Image conversion requests are added to a run queue under the IC tasks. The internal API is subsystem agnostic (no V4L2 dependency except for the use of V4L2 fourcc pixel formats). Callers prepare for image conversion by calling ipu_image_convert_prepare(), which initializes the parameters of the conversion. The caller passes in the ipu and IC task to use for the conversion, the input and output image formats, a rotation mode, and a completion callback and completion context pointer: struct ipu_image_converter_ctx * ipu_image_convert_prepare(struct ipu_soc *ipu, enum ipu_ic_task ic_task, struct ipu_image *in, struct ipu_image *out, enum ipu_rotate_mode rot_mode, ipu_image_converter_cb_t complete, void *complete_context); A new conversion context is created that is added to an IC task context queue. The caller is given the new conversion context, which can then be passed to the further APIs: int ipu_image_convert_queue(struct ipu_image_converter_run *run); This queues the given image conversion request run to a run queue, and starts the conversion immediately if the run queue is empty. Only the physaddr's of the input and output image buffers are needed, since the conversion context was created previously with ipu_image_convert_prepare(). When the conversion completes, the run pointer is returned to the completion callback. void ipu_image_convert_abort(struct ipu_image_converter_ctx *ctx); This will abort any active or pending conversions for this context. Any currently active or pending runs belonging to this context are returned via the completion callback with an error status. void ipu_image_convert_unprepare(struct ipu_image_converter_ctx *ctx); Unprepares the conversion context. Any active or pending runs will be aborted by calling ipu_image_convert_abort(). Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

2016-09-19gpu: ipu-v3: fix a possible NULL dereferenceLABBE Corentin1-3/+3
of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data. Testing the return value of of_device_get_match_data is also necessary for avoiding a second NULL deref later on devtype.

2016-08-29gpu: ipu-v3: Add FSU channel linking supportSteve Longerbeam2-0/+158
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.

2016-08-29gpu: ipu-v3: Do not wait for DMFC FIFO to clear when disabling DMFC channelLiu Ying1-17/+1
According to basic tests, it looks there is no issue if we don't wait for DMFC FIFO to clear when disabling DMFC channel. NXP BSP doesn't do that, either. This patch is needed to avoid the annoying warning caused by a timeout on waiting for the FIFO to clear after we add the new DRM_PLANE_COMMIT_NO_DISABLE_AFTER_MODESET flag to the imx-drm driver which changes the procedure to disable display channel slightly.

2016-05-23drm/imx: Match imx-ipuv3-crtc components using device node in platform dataPhilipp Zabel1-2/+3
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.

2015-10-30gpu: ipu-v3: ipu-csi: bool test doesn't need a comparison to falseFabio Estevam1-1/+1
Bool initializations should use true and false. Bool tests don't need comparisons. Based on contributions from Joe Perches, Rusty Russell and Bruce W Allan.

2015-10-06gpu: imx: fix support for interlaced modesRussell King2-46/+48
The support for interlaced video modes seems to be broken; we don't use anything other than the vtotal/htotal from the timing information to define the various sync counters. Freescale patches for interlaced video support contain an alternative sync counter setup, which we include here. This setup produces the hsync and vsync via the normal counter 2 and 3, but moves the display enable signal from counter 5 to counter 6. Therefore, we need to change the display controller setup as well. The corresponding Freescale patches for this change are: iMX6-HDMI-support-interlaced-display-mode.patch IPU-fine-tuning-the-interlace-display-timing-for-CEA.patch This produces a working interlace format output from the IPU.

2015-10-06gpu: imx: simplify sync polarity settingRussell King1-22/+28
Use a function to convert the sync pin to a bit mask for the DI_GENERAL register, and move this out of the interlace/non-interlace path to the common path.

2015-09-16gpu/drm: Kill off set_irq_flags usageRob Herring1-2/+1
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

2015-09-16genirq: Remove irq argument from irq flow handlersThomas Gleixner1-2/+2
Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!
