2023-04-13bus: qcom: remove MODULE_LICENSE in non-modulesNick Alcock
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2021-03-29bus: qcom: Put child node before returnPan Bian
Put child node before return to fix potential reference count leak. Generally, the reference count of child is incremented and decremented automatically in the macro for_each_available_child_of_node() and should be decremented manually if the loop is broken in loop body.

2016-09-08bus: qcom: add EBI2 driverLinus Walleij
This adds a driver for the Qualcomm External Bus Interface EBI2 found in the MSM8660 and APQ8060 SoCs (at least). This was tested with the SMSC9112 ethernet on the APQ8060 Dragonboard sitting on top of the SLOW CS2. Some of my understanding if very vague and based on guesses and extrapolations: the documentation in APQ8060 Qualcomm Application Processor User Guide 80-N7150-14 Rev. A describes select features but does not document the register bit fields. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
