2019-05-31drm/bridge: tc358767: disable only video stream in tc_stream_disableTomi Valkeinen
Currently the code writes 0 to DP0CTL in tc_stream_disable(), which disables the whole DP link instead of just the video stream. We always disable the link and the stream together from tc_bridge_disable(), so this doesn't cause any issues. Nevertheless, fix this by only clearing VID_EN in tc_stream_disable to stop the video stream while keeping the link enabled.

2019-05-31drm/bridge: tc358767: add link disable functionTomi Valkeinen
Currently we have tc_main_link_setup(), which configures and enabled the link, but we have no counter-part for disabling the link. Add tc_main_link_disable, and rename tc_main_link_setup to tc_main_link_enable.

2019-05-31drm/bridge: tc358767: move PXL PLL enable/disable to stream enable/disableTomi Valkeinen
We set up the PXL PLL inside tc_main_link_setup. This is unnecessary, and makes tc_main_link_setup depend on the video-mode, which should not be the case. As PXL PLL is used only for the video stream (and only when using the HW test pattern), let's move the PXL PLL setup into tc_stream_enable. Also, currently the PXL PLL is only disabled if the driver if removed. Let's disable the PXL PLL when the stream is disabled.

2019-05-31drm/bridge: tc358767: move video stream setup to tc_main_link_streamTomi Valkeinen
The driver currently sets the video stream registers in tc_main_link_setup. One should be able to establish the DP link without any video stream, so a more logical place is to configure the stream in the tc_main_link_stream. So move them there.

2019-05-31drm/bridge: tc358767: cleanup aux_link_setupTomi Valkeinen
The driver sets up AUX link at probe time, but, for some reason, also sets the main link's number of lanes using tc->link.base.num_lanes. This is not needed nor correct, as the number of lanes has not been decided yet. The number of lanes will be set later during main link setup. Modify aux_link_setup so that it does not use tc->link, and thus makes aux setup independent of the link probing.

2019-05-31drm/bridge: tc358767: fix ansi 8b10b useTomi Valkeinen
DP always uses ANSI 8B10B encoding. Some monitors (old?) may not have the ANSI 8B10B bit set in DPCD, even if it should always be set. The tc358767 driver currently respects that flag, and turns the encoding off if the monitor does not have the bit set, which then results in the monitor not working. This patch makes the driver to always use ANSI 8B10B encoding, and drops the 'coding8b10b' field which is no longer used.

2019-05-25tracing: Silence GCC 9 array bounds warningMiguel Ojeda
Starting with GCC 9, -Warray-bounds detects cases when memset is called starting on a member of a struct but the size to be cleared ends up writing over further members. Such a call happens in the trace code to clear, at once, all members after and including `seq` on struct trace_iterator: In function 'memset', inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3: ./include/linux/string.h:344:9: warning: '__builtin_memset' offset [8505, 8560] from the object at 'iter' is out of the bounds of referenced subobject 'seq' with type 'struct trace_seq' at offset 4368 [-Warray-bounds] 344 | return __builtin_memset(p, c, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In order to avoid GCC complaining about it, we compute the address ourselves by adding the offsetof distance instead of referring directly to the member. Since there are two places doing this clear (trace.c and trace_kdb.c), take the chance to move the workaround into a single place in the internal header.
