Since all sub-protocols of MHL3 are already supported MHL3 mode can be enabled. With this patch it is possible to use packed pixel modes and clocks up to 300MHz - 1920x1080@60Hz and 4K modes. Signed-off-by:

MHL3 protocol requires registry adjustments depending on chosen video mode. Necessary information is gathered in mode_fixup callback. In case of HDMI video modes driver should also send special AVI and MHL3 infoframes. The patch introduces generic helpers for handling MHL3 infoframes, in case of appearance of other users of MHL3 infoframes these function can be moved to common library. Signed-off-by:

MHL3 protocol uses vendor specific infoframes to transmit additional information to the sink. This patch adds definitions of structures and constants used to create such frames. Signed-off-by:

MHL3 requires that after reading EDID from the sink source should ask peer for features. To make both protocols happy the patch splits the code accordingly. Signed-off-by:

Stopping output causes full re-detection of the sink and slows down the process. Signed-off-by:

Write burst should be enabled for MHL_INT_RC_FEAT_REQ and disabled for other commands. The patch moves functions up and adds delay setting for MHL3 burst mode. Signed-off-by:

MHL1 and MHL3 have different initialization paths. To make both protocols happy sink detection is put into continuation after link mode enablement. Signed-off-by:

MHL3 protocol requires device to respond to feature request from peer. This minimal answer fulfills the requirement and allows to continue negotiation. Signed-off-by:

The Single-ended eCBUS Mode (eCBUS-S) mode provides 60 Mb/s full-duplex bidirectional traffic for three channels: - CBUS data (CBUS1 channel), - High-bandwidth MHL data (eMSC channel), - tunneling data (T-CBUS channel). It is required to fully support MHL3 dongles. Signed-off-by:

Due to asynchronous nature of MHL flow of execution is dispersed. Logical continuation of some actions happens after response of peer, i.e in interrupt handler. To simplify coding continuation mechanism has been added - it is now possible to provide continuation callback, which will be called after peer responds to given action. Signed-off-by:

Up until now, the bochsdrm driver didn't handle the nomodeset option at boot, and didn't provide a "modeset" module option either. This patch implements both. The new parameter can be used by specifying bochs-drm.modeset=0 at boot time. Signed-off-by:

The DSI0 and DSI1 blocks on the 2835 are related hardware blocks. Some registers move around, and the featureset is slightly different, as DSI1 (the 4-lane DSI) is a later version of the hardware block. This driver doesn't yet enable DSI0, since we don't have any hardware to test against, but it does put a lot of the register definitions and code in place. v2: Use the clk_hw interfaces, don't set CLK_IS_BASIC (from review by Stephen Boyd) Signed-off-by:Eric Anholt <eric@anholt.net> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> (v1) Link: http://patchwork.freedesktop.org/patch/msgid/20170131192912.11316-1-eric@anholt.net

We have to set a different pixel format, which tells the hardware to use the pix_width field that's fed in sideband from the DSI encoder to divide the "pixel" clock. Signed-off-by:

We want the HVS on, obviously, and we also want DSP3 (PV1's source) to be muxed from HVS channel 2 like we expect in vc4_crtc.c. The firmware wasn't setting the DSP3 mux up when both the LCD and HDMI were disabled. Signed-off-by:

This is just a cleanup, no functional change. The fixup code for 1366x768 in drm_mode_create_from_cmdline_mode() is basically a copy of the existing code in drm_edid.c. Make the latter code public so that it can be called from the former function. Signed-off-by:
