* drm: omapdrm: Replace HTTP links with HTTPS onesAlexander A. Klimov2020-11-101-1/+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.

* drm/omap: hdmi5: Rework EDID read to isolate data readLaurent Pinchart2020-02-261-40/+8
| | | | | | | | | | | | | | | | | | | | | | | In preparation of adding DRM bridge support to the hdmi5 encoder code, rework the EDID read to isolate data read. The hdmi_read_edid() function is the main entry point. It performs all initialisation steps required prior to reading the EDID (such as ensuring the device is powered on), as well as corresponding cleanup steps afterwards. EDID read itself is handled by hdmi_read_edid_data() that calls the hdmi5_core_ddc_read() function to read individual blocks. This new code architecture will allow reusing hdmi_read_edid() and hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid() function.
