2020-10-16mailbox: avoid timer start from callbackJassi Brar1-5/+7
If the txdone is done by polling, it is possible for msg_submit() to start the timer while txdone_hrtimer() callback is running. If the timer needs recheduling, it could already be enqueued by the time hrtimer_forward_now() is called, leading hrtimer to loudly complain.

This includes: - kernel-doc markup fixes - ReST fixes - Updates at the build system in order to support newer versions of the docs build toolchain (Sphinx) After this series, the number of html build warnings should reduce significantly, and building with Sphinx 3.1 or later should now be supported (although it is still recommended to use Sphinx 2.4.4). As agreed with Jon, I should be sending you a late pull request by the end of the merge window addressing remaining issues with docs build, as there are a number of warning fixes that depends on pull requests that should be happening along the merge window. The end goal is to have a clean htmldocs build on Kernel 5.10. PS. It should be noticed that Sphinx 3.0 is not currently supported, as it lacks support for C domain namespaces.

2020-10-16drm/bridge: ti-sn65dsi86: Add retries for link trainingDouglas Anderson1-11/+29
On some panels hooked up to the ti-sn65dsi86 bridge chip we found that link training was failing. Specifically, we'd see: ti_sn65dsi86 2-002d: [drm:ti_sn_bridge_enable] *ERROR* Link training failed, link is off (-5) The panel was hooked up to a logic analyzer and it was found that, as part of link training, the bridge chip was writing a 0x1 to DPCD address 00600h and the panel responded NACK. As can be seen in header files, the write of 0x1 to DPCD address 0x600h means we were trying to write the value DP_SET_POWER_D0 to the register DP_SET_POWER. The panel vendor says that a NACK in this case is not unexpected and means "not ready, try again". In testing, we found that this panel would respond with a NACK in about 1/25 times. Adding the retry logic worked fine and the most number of tries needed was 3. Just to be safe, we'll add 10 tries here and we'll add a little blurb to the logs if we ever need more than 5.
