| * drm/msm/dsi: Fix some reference counted resource leaksChristophe JAILLET2021-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 6977cc89c87506ff17e6c05f0e37f46752256e82 ] 'of_find_device_by_node()' takes a reference that must be released when not needed anymore. This is expected to be done in 'dsi_destroy()'. However, there are 2 issues in 'dsi_get_phy()'. First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()' returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference won't be released in 'dsi_destroy()'. Secondly, as 'of_find_device_by_node()' already takes a reference, there is no need for an additional 'get_device()'. Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the unneeded 'get_device()' to solve both issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 78e31c42261779a01bc73472d0f65f15378e9de3 ] On msm8998, vblank timeouts are observed because the DSI controller is not reset properly, which ends up stalling the MDP. This is because the reset logic is not correct per the hardware documentation. The documentation states that after asserting reset, software should wait some time (no indication of how long), or poll the status register until it returns 0 before deasserting reset. wmb() is insufficient for this purpose since it just ensures ordering, not timing between writes. Since asserting and deasserting reset occurs on the same register, ordering is already guaranteed by the architecture, making the wmb extraneous. Since we would define a timeout for polling the status register to avoid a possible infinite loop, lets just use a static delay of 20 ms, since 16.666 ms is the time available to process one frame at 60 fps.

* | drm/msm: Separate locking of buffer resources from struct_mutexSushmita Susheelendra2017-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | Buffer object specific resources like pages, domains, sg list need not be protected with struct_mutex. They can be protected with a buffer object level lock. This simplifies locking and makes it easier to avoid potential recursive locking scenarios for SVM involving mmap_sem and struct_mutex. This also removes unnecessary serialization when creating buffer objects, and also between buffer object creation and GPU command submission.

* | drm/msm: Use 64 bit containers for iovasJordan Crouse2017-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer Adreno GPUs are able to support 64 bit virtual addressing. To prepare for this brave new world switch all IOVA related variables and members to a uint64_t container. This is harmless for the display and older targets that do not have 64 bit addressing because a 32 bit address is just a 64 bit address with lots of zeros. To avoid ambiguity and compiler oddness make sure to use lower_32_bits() and upper_32_bits() everywhere the IOVA is used to ensure that you get what you expect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are platforms where the DSI output can be connected to another encoder bridge chip (DSI to HDMI, DSI to LVDS etc). Add support for external bridge support to the dsi driver. We assume that the external bridge chip would be of the type drm_bridge. The dsi driver's internal drm_bridge (msm_dsi->bridge) is linked to the external bridge's drm_bridge struct. In the case we're connected to an external bridge, we don't need to create and manage a connector within our driver, it's the bridge driver's responsibility to create one. v2: - Move the external bridge attaching stuff to dsi manager to make things cleaner. - Force the bridge to connect to a video mode encoder for now (the dsi mode flags may have not been populated by modeset_init) Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

This check gets messy when we have support external bridges too. Having an inline function makes it more legible. For now, the check only consists of msm_dsi->panel being non-NULL. Later, this will check if we have an external bridge or not. This helper isn't used in dsi_connector related code as that's specific to only when a drm_panel is connected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dsi host looks for the connected panel node by parsing for a child named 'panel'. This hierarchy isn't very flexible. The connected panel is forced to be a child to the dsi host, and hence, a mipi dsi device. This isn't suitable for dsi devices that don't use mipi dsi as their control bus. Follow the of_graph approach of creating ports and endpoints to represent the connections between the dsi host and the panel connected to it. In our case, the dsi host will only have one output port, linked to the panel's input port. Update DT binding documentation with device graph usage info. v3: - Fix return value checks of of_graph_* calls. - Don't make port a mandatory DT property - Fix defer check when no panel node specified - Rename parse_dt func to align with other dsi_host funcs Reviewed-by: Hai Li <hali@codeaurora.org> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | DSI PHY errors are falsely reported whenever a dsi error occurs. This is because DSI_DLN0_PHY_ERR isn't only used as a status register, but also used to mask PHY errors. Currently, we end up reading the mask bits too and therefore always report errors.

* drm/msm: use devm_gpiod_get_optional for optional reset gpioUwe Kleine-König2015-06-11
| | | | | | | | | | | | | | | | | | | | | | Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Also there is a variant to find optional gpios that returns NULL if there is no gpio instead of -ENOENT. Make use of both features to simplify the driver. This makes error checking more strict because errors like -ENOSYS ("no gpio support compiled in") or -EPROBE_DEFER ("gpio not ready yet") are handled correctly now. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.
