2024-06-10drm/sun4i: Fix layer zpos change/atomic modesettingOndrej Jirman4-143/+71
Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

2023-09-21drm: Call drm_atomic_helper_shutdown() at shutdown time for misc driversDouglas Anderson1-0/+6
Based on grepping through the source code these drivers appear to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c. All of the drivers in this patch were fairly straightforward to fix since they already had a call to drm_atomic_helper_shutdown() at remove/unbind time but were just lacking one at system shutdown. The only hitch is that some of these drivers use the component model to register/unregister their DRM devices. The shutdown callback is part of the original device. The typical solution here, based on how other DRM drivers do this, is to keep track of whether the device is bound based on drvdata. In most cases the drvdata is the drm_device, so we can just make sure it is NULL when the device is not bound. In some drivers, this required minor code changes. To make things simpler, drm_atomic_helper_shutdown() has been modified to consider a NULL drm_device as a noop in the patch ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop").

2023-08-22clk: Annotate struct clk_hw_onecell_data with __counted_byKees Cook1-2/+1
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

2023-07-21drm: Explicitly include correct DT includesRob Herring8-8/+12
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-06-08drm/sun4i: Convert to platform remove callback returning voidUwe Kleine-König11-44/+22
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the sun4i drm drivers from always returning zero in the remove callback to the void returning variant.

2023-06-01drm/sun4i: hdmi: Replace all non-returning strlcpy with strscpyAzeem Shaikh1-1/+1
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

2023-05-11drm: sun4i_tcon: use devm_clk_get_enabled in `sun4i_tcon_init_clocks`XuDong Liu1-15/+4
Smatch reports: drivers/gpu/drm/sun4i/sun4i_tcon.c:805 sun4i_tcon_init_clocks() warn: 'tcon->clk' from clk_prepare_enable() not released on lines: 792,801. In the function sun4i_tcon_init_clocks(), tcon->clk and tcon->sclk0 are not disabled in the error handling, which affects the release of these variable. Although sun4i_tcon_bind(), which calls sun4i_tcon_init_clocks(), use sun4i_tcon_free_clocks to disable the variables mentioned, but the error handling branch of sun4i_tcon_init_clocks() ignores the required disable process. To fix this issue, use the devm_clk_get_enabled to automatically balance enable and disabled calls. As original implementation use sun4i_tcon_free_clocks() to disable clk explicitly, we delete the related calls and error handling that are no longer needed.

2022-09-08drm/sun4i: tv: Merge mode_set into atomic_enableMaxime Ripard1-15/+10
Our mode_set implementation can be merged into our atomic_enable implementation to simplify things, so let's do this.

2022-09-07drm/sun4i: tv: Add missing reset assertionMaxime Ripard1-0/+1
The reset line is deasserted at bind, and asserted if we ever encounter an error there. However, it's never asserted in unbind which will lead to a resource unbalance.

2022-09-07drm/sun4i: tv: Rename error labelMaxime Ripard1-2/+2
The other error labels in sun4i_tv_bind() are named after the task they perform (err_disable_clk to call clk_disable_unprepare for example). However, the err_cleanup_connector is named after the calling site (drm_connector_init failing) and will actually cleanup the encoder. Let's rename it to err_cleanup_encoder to be consistent.

2022-09-07drm/sun4i: tv: Remove useless destroy functionMaxime Ripard1-7/+1
Our destroy implementation is just calling the generic helper, so let's just remove our function and directly use the helper.
