fbdev: mmp: Use devm_clk_get_enabled() helpers

2024-08-30T16:42:38+00:00

The devm_clk_get_enabled() helpers: - call devm_clk_get() - call clk_prepare_enable() and register what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the calls to clk_disable_unprepare(). Signed-off-by: ying zuxin Signed-off-by: Helge Deller

fbdev: mmp: Constify struct mmp_overlay_ops

2024-06-25T12:40:01+00:00

'struct mmp_overlay_ops' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 11798 555 16 12369 3051 drivers/video/fbdev/mmp/hw/mmp_ctrl.o After: ===== text data bss dec hex filename 11834 507 16 12357 3045 drivers/video/fbdev/mmp/hw/mmp_ctrl.o Signed-off-by: Christophe JAILLET Signed-off-by: Helge Deller

video: fbdev: mmp: Follow renaming of SPI "master" to "controller"

2024-02-08T11:54:58+00:00

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"") some functions and struct members were renamed. To not break all drivers compatibility macros were provided. To be able to remove these compatibility macros push the renaming into this driver.

Merge tag 'drm-misc-next-2023-09-27' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

2023-09-28T22:27:15+00:00

drm-misc-next for v6.7-rc1: UAPI Changes: - drm_file owner is now updated during use, in the case of a drm fd opened by the display server for a client, the correct owner is displayed. - Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo recycling. Cross-subsystem Changes: - Disable boot logo for au1200fb, mmpfb and unexport logo helpers. Only fbcon should manage display of logo. - Update freescale in MAINTAINERS. - Add some bridge files to bridge in MAINTAINERS. - Update gma500 driver repo in MAINTAINERS to point to drm-misc. Core Changes: - Move size computations to drm buddy allocator. - Make drm_atomic_helper_shutdown(NULL) a nop. - Assorted small fixes in drm_debugfs, DP-MST payload addition error handling. - Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling. - Handle bad (h/v)sync_end in EDID by clipping to htotal. - Build GPUVM as a module. Driver Changes: - Simple drivers don't need to cache prepared result. - Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot more drm drivers. - Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic, nouveau, tc358768. - Add NV12 for komeda writeback. - Add arbitration lost event to synopsis/dw-hdmi-cec. - Speed up s/r in nouveau by not restoring some big bo's. - Assorted nouveau display rework in preparation for GSP-RM, especially related to how the modeset sequence works and the DP sequence in relation to link training. - Update anx7816 panel. - Support NVSYNC and NHSYNC in tegra. - Allow multiple power domains in simple driver.

fbdev: mmp: Annotate struct mmphw_ctrl with __counted_by

2023-09-23T18:35:14+00:00

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 mmphw_ctrl.

fbdev/mmp/mmpfb: Do not display boot-up logo

2023-09-11T13:12:31+00:00

The fbcon module takes care of displaying the logo, if any. Remove the code form mmpfb. It is probably no tworking as expected, as it interferes with the framebuffer console. If we want to display the logo without fbcon, we should implement this in the fbdev core code. v2: * add a note on fbcon interference (Javier) Signed-off-by: Thomas Zimmermann Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230907085408.9354-3-tzimmermann@suse.de
