Commit 1bdb542d ("drm/ingenic: Simplify code by using hwdescs array") caused the dma_hwdesc_phys_f{0,1} variables to be used while uninitialized in a mmio register write, which most certainly broke the ingenic-drm driver. However, the very same patchset also submitted commit 60554662 ("drm/ingenic: Upload palette before frame"), which restored a correct behaviour by doing the register writes in a different place in the code. What's left of this, is just to remove the bogus register writes in the probe function. Signed-off-by:

When using C8 color mode, make sure that the palette is always uploaded before a frame; otherwise the very first frame will have wrong colors. Do that by changing the link order of the DMA descriptors. v3: Fix ingenic_drm_get_new_priv_state() called instead of ingenic_drm_get_priv_state() Signed-off-by: -
Paul Cercueil authored
Setting the DMA descriptor chain register in the probe function has been fine until now, because we only ever had one descriptor per foreground. As the driver will soon have real descriptor chains, and the DMA descriptor chain register updates itself to point to the current descriptor being processed, this register needs to be reset after a full modeset to point to the first descriptor of the chain.

The IPU scaling information is computed in the plane's ".atomic_check" callback, and used in the ".atomic_update" callback. As such, it is state-specific, and should be moved to a private state structure. Signed-off-by:

Until now, the ingenic-drm as well as the ingenic-ipu drivers used to put state-specific information in their respective private structure. Add boilerplate code to support private objects in the two drivers, so that state-specific information can be put in the state-specific private structure. Signed-off-by:

Instead of having one 'hwdesc' variable for the plane #0, one for the plane #1 and one for the palette, use a 'hwdesc[3]' array, where the DMA hardware descriptors are indexed by the plane's number. v2: dma_hwdesc_addr() extended to support palette hwdesc. The palette hwdesc is now hwdesc[3] to simplify things. Add ingenic_drm_configure_hwdesc*() functions to factorize code. Signed-off-by: -

The left shift of unsigned int 32 bit integer constant 1 is evaluated using 32 bit arithmetic and then assigned to a signed 64 bit integer.

When built without CONFIG_PWM there are no references to ti_sn65dsi86_read_u16(), avoid the W=1 build warning by marking the function as __maybe_unused. __maybe_unused is used insted of a #ifdef guard as it looks slighly cleaner and it avoids issues if in the future other permutations of the config options would use the function.

In this patch(https://patchwork.freedesktop.org/patch/310349), it add a new IOCTL to support dma-buf user to set debug name. But it also added a limitation of this IOCTL, it needs the attachments of dmabuf should be empty, otherwise it will fail. For the original series, the idea was that allowing name change mid-use could confuse the users about the dma-buf. However, the rest of the series also makes sure each dma-buf have a unique inode(https://patchwork.freedesktop.org/patch/310387/), and any accounting should probably use that, without relying on the name as much. So, removing this restriction will let dma-buf userspace users to use it more comfortably and without any side effect. Signed-off-by:

Without proper care and an agreement between how DSI hosts and devices drivers register their MIPI-DSI entities and potential components, we can end up in a situation where the drivers can never probe. Most drivers were taking evasive maneuvers to try to workaround this, but not all of them were following the same conventions, resulting in various incompatibilities between DSI hosts and devices. Now that we have a sequence agreed upon and documented, let's convert kirin to it. Acked-by:

Commit 24417d5b ("drm/bridge: ti-sn65dsi83: Implement .detach callback") moved the unregistration of the bridge DSI device and bridge itself to the detach callback. While this is correct for the DSI device detach and unregistration, the bridge is added in the driver probe, and should thus be removed as part of its remove callback. Acked-by:

The multi-register u16 write operation can use regmap_bulk_write() instead of two separate regmap_write() calls. It's uncertain if this has any effect on the actual updates of the underlying registers, but this at least gives the hardware the opportunity and saves us one transation on the bus. Signed-off-by:

The existing pxa driver and the upcoming addition of PWM support in the TI sn565dsi86 DSI/eDP bridge driver both has a single PWM channel and thereby a need for a of_xlate function with the period as its single argument. Introduce a common helper function in the core that can be used as of_xlate by such drivers and migrate the pxa driver to use this. Signed-off-by:
