v6 - A few more changes based on requests from Greg Kroah-Hartman - Don't save the debugfs file handle in priv because it was never used. - Change all dev_info() messages to dev_dbg() messages. - Fix warnings from the kernel test robot - Use --base with "git format-patch" - Fixes in the .yaml file based on requests from Rob Herring - Change "oneOf" to "minItems: 1". - Reference serial.yaml instead of using "$nodname". - Add missing newline. v5 - Changes based on requests from Greg Kroah-Hartman - Move sysfs stats to debugfs. - Merge the .h file into the .c file. - Convert "flags" with only one flag to bool - Remove most dev_dbg() messages. Some can be replaced by using ftrace and some would cause a crash if the driver was used for the console. v4 - Fix MAINTAINERS - Make all changes requested by Jira Slaby. The only functional change was to handle errors returned by brcmuart_arbitration() in brcmuart_resume(). v3 - remove "disable_dma" module param because it can be done by modifying the device tree node instead. Reduce size by removing some debug fuctionality that was no longer used. - Fix error from yaml compiler in bindings v2 - remove the patch that modified 8250_of.c to keep it from registering before this driver when this driver was deferred as it was getting it's "clocks". This was fixed by changing the Device Tree entry to remove "clock-frequency". This results in both drivers getting "clocks" and getting same the deferral.
