v7 - Change Kconfig for SERIAL_8250_BCM7271 from "bool" to "tristate"
so the driver can be built as a module.
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.
