2020-12-15drm/omap: dsi: send nop instead of page & columnTomi Valkeinen
The OMAP DSI command mode panel driver used to send page & column address before each frame update, and this code was moved into the DSI host driver when converting it to the DRM bridge model. However, it's not really required to send the page & column address before each frame. It's also something that doesn't really belong to the DSI host driver, so we should drop the code. That said, frame updates break if we don't send _something_ between the frames. A NOP command does the trick. It is not clear if this behavior is as expected from a DSI command mode frame transfer, or is it a feature/issue with OMAP DSI driver, or a feature/issue in the command mode panel used. Most likely this is related to the following from the DSI spec: "To enable PHY synchronization the host processor should periodically end HS transmission and drive the Data Lanes to the LP state. This transition should take place at least once per frame."

But as we currently only support a single DSI command mode panel, this works fine: we always use VC0, and VC ID 0.

2020-11-30drm/omap: sdi: fix bridge enable/disableTomi Valkeinen
When the SDI output was converted to DRM bridge, the atomic versions of enable and disable funcs were used. This was not intended, as that would require implementing other atomic funcs too. This leads to: WARNING: CPU: 0 PID: 18 at drivers/gpu/drm/drm_bridge.c:708 drm_atomic_helper_commit_modeset_enables+0x134/0x268 and display not working. Fix this by using the legacy enable/disable funcs.

2020-11-10drm/omap: Fix runtime PM imbalance on errorDinghao Liu
pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. However, users of its direct wrappers in omapdrm assume that PM usage counter will not change on error. Thus a pairing decrement is needed on the error handling path for these wrappers to keep the counter balanced.

2020-11-10drm: omapdrm: Replace HTTP links with HTTPS onesAlexander A. Klimov
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.
