Merge tag 'drm-for-v4.14' into dev-4.13

2018-04-19T02:00:20+00:00

This is the DRM tree that was merged into the mainline 4.14 kernel. The ASPEED GFX DRM driver requires functionaliy that was included in this tree, so we merge it back into the 4.13 OpenBMC tree. This should have no impact on other parts of the BMC. Signed-off-by: Joel Stanley

drm/bridge/sii8620: Fix memory corruption

2017-08-24T17:06:32+00:00

Function sii8620_mt_read_devcap_reg_recv() used to read array index from a wrong msg register, which caused writing out of array bounds. It led to writing on other fields of struct sii8620.

Linux 4.13-rc5 There's a really nasty nouveau collision, hopefully someone can take a look once I pushed this out.

drm: bridge: dw-hdmi: constify snd_pcm_ops structures

2017-08-09T10:27:29+00:00

snd_pcm_ops are not supposed to change at runtime. All functions working with snd_pcm_ops provided by work with const snd_pcm_ops. So mark the non-const structs as const.

drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48+00:00

It's dead code, the core handles all this directly now. The only special case is nouveau and tda988x which used one function for both legacy modeset code and -nv50 atomic world instead of 2 vtables. But amounts to exactly the same. v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: bridge: synopsys/dw-hdmi: Provide default configuration function for HDMI 2.0 PHY

2017-08-08T08:39:56+00:00

Currently HDMI 2.0 PHYs do not have a default configuration function. As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D PHYs we can provide the same default configuration function for both and still let user overwrite this with custom configuration function if needed. If, for some reason, the PHY is custom or has a register different register layout then custom configuration function *must* be provided in order for the system to work correctly. As we prefer the pdata provided configuration function over the internal one this change will not make any impact in custom platforms.
