The wiring of the RS-485 transceiver of UART0 of the PDU-001 board
allows sending or receiving date exclusively. In other words: no
character transmitted will ever be received.
Hence the tx-filter counter in the OMAP serial driver can't work
correctly as it relies on receiving the transmitted characters.
This in turn will prevent reception of data unless we disable the
tx-filter counter.
This patch disables the tx-filter counter by enabling the DTS setting
rs485-rx-during-tx. This might sound like the opposite to be done but
it uses the enabling of rs485-rx-during-tx not for receiving the data
transmitted but for disabling the tx-fiter counter.

The 'rts-gpio' (without trailing 's') is deprecated in favor of
'rts-gpios'. Kernel supports both variants, so switch the DTS to
preferred one.

DT schema expects panel timings node to follow certain pattern,
dtbs_check warnings:
am335x-pdu001.dtb: display-timings: '240x320p16' does not match any of the regexes: '^timing', 'pinctrl-[0-9]+'
Linux drivers do not care about node name, so this should not have
effect on Linux.

Move the pending urls back to https:// and mark the ones that are no
longer accessible (http or https) as defunct.

The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.
