drm/panel-simple: Non-eDP panels don't need "HPD" handling

2021-09-20T16:23:01+00:00

All of the "HPD" handling added to panel-simple recently was for eDP panels. Remove it from panel-simple now that panel-edp handles eDP panels. The "prepare_to_enable" delay only makes sense in the context of HPD, so remove it too. No non-eDP panels used it anyway.

drm/panel-edp: Move some wayward panels to the eDP driver

2021-09-20T16:22:41+00:00

Not all panels in panel-simple were marked what type of panel they were. I searched through ARM/ARM64 Chromebooks or Chromebook-related reference boards that I was aware of and found some panels that needed to be moved. I also skimmed for panels that had no mode and were "big" since it's quite rare to see a small eDP panel. Here's what I found: * auo,b101ean01 - rk3288-veyron-minnie * auo,b133htn01 - exynos5800-peach-pi * auo,b133xtn01 - tegra124-nyan-big * boe,nv101wxmn51 - rk3399-gru-bob * innolux,p120zdg-bf1 - sdm845-cheza * lg,lp079qx1-sp0v - rk3399-evb and similar * lg,lp097qx1-spa1 - According to commit 0355dde26e52 ("drm/panel: simple: Add support for LG LP097QX1-SPA1 panel") this is an eDP panel. * lg,lp129qe - tegra124-venice2 * samsung,lsn122dl01-c01 - According to commit 0330eaf39082 ("drm/panel: simple: Add support for Samsung LSN122DL01-C01 panel") this is an eDP panel. * samsung,ltn140at29-301 - tegra124-nyan-blaze * sharp,ld-d5116z01b - According to commit cd5e1cbe1f0a ("drm/panel: simple: Add support for Sharp LD-D5116Z01B panel") this is an eDP panel. * sharp,lq123p1jx31 - rk3399-gru-kevin * starry,kr122ea0sra - rk3399-gru-gru (reference board, not upstream) I won't promise that I didn't miss a single panel, but that's fairly complete I think. I'm not sure the full impact of the fact that they didn't have the connector type specified, but at least as of commit 9f069c6fbc72 ("drm/panel: panel-simple: add default connector_type") we may have been accidentally thinking of them as DPI panels. We also would certainly have had a warning. In any case since we don't want to support anything eDP in the old simple-panel driver, we should move these.

drm/panel-edp: Split eDP panels out of panel-simple

2021-09-20T16:22:05+00:00

The panel-simple driver handles way too much. Let's start trying to get a handle on it by splitting out the eDP panels. This patch does this: 1. Start by copying simple-panel verbatim over to a new driver, simple-panel-edp. 2. Rename "panel_simple" to "panel_edp" in the new driver. 3. Keep only panels marked with `DRM_MODE_CONNECTOR_eDP` in the new driver. Remove those panels from the old driver. 4. Remove all recent "DP AUX bus" stuff from the old driver. The DP AUX bus is only possible on DP panels. 5. Remove all DSI / MIPI related functions from the new driver. 6. Remove bus_format / bus_flags from eDP driver. These things don't seem to make any sense for eDP panels so let's stop filling in made up stuff. In the end we end up with a bunch of duplicated code for now. Future patches will try to address _some_ of this duplicated code though some of it will be unavoidable. NOTE: This may not actually move all eDP panels over to the new driver since not all panels were properly marked with `DRM_MODE_CONNECTOR_eDP`. A future patch will attempt to move wayward panels I could identify but even so there may be some missed.

drm/panel-simple: Reorder logicpd_type_28 / mitsubishi_aa070mc01

2021-09-09T20:00:36+00:00

The "logicpd_type_28" panel data was splitting up the mitsubishi_aa070mc01 panel data. Reorganize it so that the panel descs and modes are kept together. This is a no-op code-cleanup change, found by code inspection.

Pull drm updates from Dave Airlie: "Highlights: - i915 has seen a lot of refactoring and uAPI cleanups due to a change in the upstream direction going forward This has all been audited with known userspace, but there may be some pitfalls that were missed. - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs - i915 enables Jasper and Elkhart Lake by default and has preliminary XeHP/DG2 support - amdgpu adds support for Cyan Skillfish - lots of implicit fencing rules documented and fixed up in drivers - msm now uses the core scheduler - the irq midlayer has been removed for non-legacy drivers - the sysfb code now works on more than x86. Otherwise the usual smattering of stuff everywhere, panels, bridges, refactorings.
