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:

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 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:

The function is not that big, but it's also not used for anything performance critical. Make it a normal function. As a side effect, this apparently makes sparse smarter about what it's doing, and gets rid of the warning: ./include/drm/drm_color_mgmt.h:53:28: warning: shift too big (4294967295) for type unsigned long ./include/drm/drm_color_mgmt.h:53:28: warning: cast truncates bits from constant value (8000000000000000 becomes 0) v2: rebased Cc: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by:

The size computations done in the ioctl function use an integer. If userspace submits a request with req->cmd_nr or req->cmd_buf_nr set to INT_MAX, the integer computations overflow later, leading to potential (kernel) memory corruption. Prevent this issue by enforcing a limit on the number of submitted commands, so that we have enough headroom later for the size computations. Note that this change has no impact on the currently available users in userspace, like e.g. libdrm/exynos. While at it, also make a comment about the size computation more detailed. Signed-off-by:

We were trying to print an error message if we timed out here, but the loop actually ends with "tries" set to UINT_MAX and not zero. Fix this by changing from tries-- to --tries. A for loop would actually be the most natural way to do this. My fix means we only loop 99 times instead of 100 but that's probably ok.
