The U8540 was an evolved version of the U8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the U8500.

These files were created and ever touched by a group of three people
only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC.
Introducing and discussing SPDX-License-Identifier resulted in a
conclusion that ISC is a not recommended license (see also a
license-rules.rst). Moveover an old e-mail from Alan Cox was pointed
which explained that dual licensing is a safer solution than depending
on a common compatibility belief.
This commit switches most of BCM5301X DTS files to dual licensing using:
1) GPL 2.0+ to make sure they are compatible with Linux kernel
2) MIT to allow sharing with more permissive projects
Both licenses belong to the preferred ones (see LICENSES/preferred/).
An attempt to relicense remaining files will be made separately and will
require approve from more/other developers.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find arch/arm/boot/dts -type f \( -iname "*.dts" -o -iname "*.dtsi" \) -exec sed -i \
-e "s/@\([0-9a-fA-FxX\.;:#]\+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 \
{/g" -e "s/@0\+\(.\+\) {/@\1 {/g" {} +
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve also a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.
According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.
In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.
Add a new pinctrl group for clock line without pullup to be used in boards
where mmc1_clk line is not connected to an external pullup.
