Nowadays sdhci prevents runtime suspend when SDIO IRQs are enabled. However, some variants such as sdhci-esdhc-imx's, tries to allow runtime suspend while having the SDIO IRQs enabled, but without supporting remote wakeups. This support is a bit questionable, especially if the host device have a PM domain attached that can be power gated, but more importantly, the code have also become redundant (which was not the case when it was introduced). Rather than keeping the redundant code around, let's drop it and leave this to be revisited later on. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
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.
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.
