2023-07-10drm/tidss: Update encoder/bridge chain connect modelAradhya Bhatia1-2/+3
With the new encoder/bridge chain model, the display controller driver is required to create a drm_connector entity instead of asking the bridge to do so during drm_bridge_attach. Moreover, the controller driver should create a drm_bridge entity to negotiate bus formats and a 'simple' drm_encoder entity to expose it to userspace. Update the encoder/bridge initialization sequence in tidss as per the new model.

2020-07-16drm/tidss: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-01-27drm/tidss: New driver for TI Keystone platform Display SubSystemJyri Sarha1-0/+17
This patch adds a new DRM driver for Texas Instruments DSS IPs used on Texas Instruments Keystone K2G, AM65x, and J721e SoCs. The new DSS IP is a major change to the older DSS IP versions, which are supported by the omapdrm driver. While on higher level the Keystone DSS resembles the older DSS versions, the registers are completely different and the internal pipelines differ a lot. DSS IP found on K2G is an "ultra-light" version, and has only a single plane and a single output. The K3 DSS IPs are found on AM65x and J721E SoCs. AM65x DSS has two video ports, one full video plane, and another "lite" plane without scaling support. J721E has 4 video ports, 2 video planes and 2 lite planes. AM65x DSS has also an integrated OLDI (LVDS) output. Version history: v2: - rebased on top of drm-next-2019-11-27 - sort all include lines in all files - remove all include <drm/drmP.h> - remove select "select VIDEOMODE_HELPERS" - call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no to call it in new modeset case as it is also called in vp_enable()) - change probe sequence and drm_device allocation (follow example in drm_drv.c) - use __maybe_unused instead of #ifdef for pm functions - remove "struct drm_fbdev_cma *fbdev;" from driver data - check panel connector type before connecting it v3: no change v4: no change v5: - remove fifo underflow irq handling, it is not an error and it should be used for debug purposes only - memory tuning, prefetch plane fifo up to high-threshold value to minimize possibility of underflows. v6: - Check CTM and gamma support from dispc_features when creating crtc - Implement CTM support for k2g and fix k3 CTM implementation - Remove gamma property persistence and always write color properties in a new modeset v7: - Fix checkpatch.pl --strict issues - Rebase on top of drm-misc-next-2020-01-10 v8: - Remove idle debug prints from dispc_init() - Add Reviewed-by: Benoit Parrot <bparrot@ti.com> v9: - Rename dispc_write_irqenable() to dispc_set_irqenable() to avoid conflict exported omapfb function with same name - Add Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Co-developed-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Jyri Sarha <jsarha@ti.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Benoit Parrot <bparrot@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/925fbfad58ff828e8e07fdff7073a0ee65750c3d.1580129724.git.jsarha@ti.com
