Instead of using of_property_read_bool to check the presence of the cdns,phy-* properties in the device tree, use of_property_present in function sdhci_cdns_phy_param_count. This silences the following warning messages since the cdns,phy-* properties are all u32, not boolean. OF: /soc/sdhci@d8010000: Read of boolean property 'cdns,phy-input-delay-legacy' with a value. OF: /soc/sdhci@d8010000: Read of boolean property 'cdns,phy-input-delay-mmc-highspeed' with a value. OF: /soc/sdhci@d8010000: Read of boolean property 'cdns,phy-input-delay-mmc-ddr' with a value. OF: /soc/sdhci@d8010000: Read of boolean property 'cdns,phy-dll-delay-sdclk' with a value. OF: /soc/sdhci@d8010000: Read of boolean property 'cdns,phy-dll-delay-sdclk-hsmmc' with a value.

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 reStructuredText 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.
