The RP1 firmware runs a simple communications channel over some shared memory and a mailbox. This driver provides access to that channel. Signed-off-by: Phil Elwell <phil@raspberrypi.com> firmware: rp1: Simplify rp1_firmware_get Simplify the implementation of rp1_firmware_get, requiring its clients to have a valid 'firmware' property. Also make it return NULL on error. Link: https://github.com/raspberrypi/linux/issues/6593 Signed-off-by: Phil Elwell <phil@raspberrypi.com> firmware: rp1: Linger on firmware failure To avoid pointless retries, let the probe function succeed if the firmware interface is configured correctly but the firmware is incompatible. The value of the private drvdata field holds the outcome. Link: https://github.com/raspberrypi/linux/issues/6642 Signed-off-by: Phil Elwell <phil@raspberrypi.com> firmware: rp1: Rename to rp1-fw to avoid module name collision There is already the driver in drivers/mfd/rp1.ko, so having drivers/firmware/rp1.ko can cause issues when using modinfo and similar, and we can get errors with "Module rp1 is already loaded" when trying to load it. Rename the module so that the name is unique. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com> mailbox: rp1: Don't claim channels in of_xlate The of_xlate method saves the calculated event mask in the con_priv field. It also rejects subsequent attempt to use that channel because the mask is non-zero, which causes a repeated instantiation of a client driver to fail. The of_xlate method is not meant to be a point of resource acquisition. Leave the con_priv initialisation, but drop the test that it was previously zero.

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.
