* serial: 8250: remove the redundant includeWang Long2015-03-26
| | | | | | | | | | The serial_core.h file have been included in header file serial_8250.h. so remove the "#include <serial_core.h>" in some 8250 serial drivers, because they have included the header file serial_8250.h.

They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

| | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

| | | | | | | | | | | Update the 8250_em driver to correctly handle the case where no clock is associated with the device. The return value of clk_get() needs to be checked with IS_ERR() to avoid NULL pointer referencing.

* serial8250-em: Emma Mobile UART driver V2Magnus Damm2012-05-04
This is V2 of the Emma Mobile 8250 platform driver. The hardware itself has according to the data sheet up to 64 byte FIFOs but at this point we only make use of the 16550 compatible mode. To support this piece of hardware the common UART registers need to be remapped, and the access size differences need to be handled. The DLL and DLM registers can due to offset collision not be remapped easily, and because of that this driver makes use of ->dl_read() and ->dl_write() callbacks. This in turn requires a registration function that takes 8250-specific paramenters. Future potential enhancements include DT support, early platform driver console and fine grained PM.
