Janusz Krzysztofik d08605a64e ARM: OMAP1: ams-delta: move late devices back to init_machine 
Initialization of several Amstrad Delta devices was once moved to
late_initcall by commit f7519d8c82 ("ARM: OMAP1: ams-delta: register
latch dependent devices later").  The purpose of that move was to allow
smooth conversion of Amstrad Delta latches to GPIO.

After successful conversion only ams_delta_serio driver was moved back
to device_initcall by commit 8d09a1bb31 ("input: serio: ams-delta:
toggle keyboard power over GPIO").  Registration of ams-delta-nand and
lcd_ams_delta devices was kept in late_initcall in order to avoid
corrupt data reported by the serio driver on boot.  Registration of
cx20442-codec device was kept there for it to be probed after a
regulator on which it depended was ready.

The issue of "keybrd_dataout" GPIO pin not initilized to GPIO_OUT_LOW
before other latch2 pins causing the corruption have been apparently
fixed by commit 5322c19b117a ("ARM: OMAP1: ams-delta: Hog
"keybrd_dataout" GPIO pin").  In turn, the issue of missing regulator
has been fixed by commit 50c678772a ("ASoC: cx20442: Don't ignore
regulator_get() errors.").

Simplify the board init code by moving registration of those devices
back to init_machine.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
