This patch marks all the gsbi i2c node at soc level dtsi, so that kernel would not assume that its enabled and result in pin conflicts when gsbi is used for UART or SPI. Without this patch we see below pin conflict. apq8064-pinctrl 800000.pinctrl: pin GPIO_20 already requested by 12450000.serial; cannot claim for 12460000.i2c apq8064-pinctrl 800000.pinctrl: pin-20 (12460000.i2c) status -22 apq8064-pinctrl 800000.pinctrl: could not request pin 20 (GPIO_20) from group gpio20 on device 800000.pinctrl i2c_qup 12460000.i2c: Error applying setting, reverse things back i2c_qup: probe of 12460000.i2c failed with error -22 Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@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.
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.
