Arnd Bergmann 92e830f25f x86/olpc: Fix inconsistent MFD_CS5535 configuration
This Kconfig warning appeared after a fix to the Kconfig validation.
The GPIO_CS5535 driver depends on the MFD_CS5535 driver, but the former
is selected in places where the latter is not:

WARNING: unmet direct dependencies detected for GPIO_CS5535
  Depends on [m]: GPIOLIB [=y] && (X86 [=y] || MIPS || COMPILE_TEST [=y]) && MFD_CS5535 [=m]
  Selected by [y]:
  - OLPC_XO1_SCI [=y] && X86_32 [=y] && OLPC [=y] && OLPC_XO1_PM [=y] && INPUT [=y]=y

The warning does seem appropriate, since the GPIO_CS5535 driver won't
work unless MFD_CS5535 is also present. However, there is no link time
dependency between the two, so this caused no problems during randconfig
testing before.

This changes the 'select GPIO_CS5535' to 'depends on GPIO_CS5535' to
avoid the issue, at the expense of making it harder to configure the
driver (one now has to select the dependencies first).

The 'select MFD_CORE' part is completely redundant, since we already
depend on MFD_CS5535 here, so I'm removing that as well.

Ideally, the private symbols exported by that cs5535 gpio driver would
just be converted to gpiolib interfaces so we could expletely avoid
this dependency.

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
