[PATCH v8 0/2] Add Spreadtrum SoC bindings and serial driver support

[Chunyan Zhang]

This patch-set split the last version, and addressed the review comments from
last version on serial driver code.

Changes from v7:
* Addressed review comments from Peter:
	- Initialized the stack local with zero in sprd_set_termios()
	- Used dev_get_drvdata() to get sprd_uart_port

Changes from v6:
	- Setted SPRD_TIMEOUT with 256 rather than 2048
	- Used u32 instead of uint32_t
	- Removed inline of handle_lsr_errors which is a single call site function
	- Removed unused parameter of sprd_tx & sprd_rx
	- Used spin_lock_irqsave in sprd_startup() instead of spin_lock
	- Added a check for port->sysrq in sprd_console_write()
	- Used a global counter as a condition of calling uart_{un}register_driver
	- Added pdev->id assignment in probe()
	- Setted port->flags with UPF_BOOT_AUTOCONF instead of ASYNC_BOOT_AUTOCONF

Changes from v5:
	- Used Spreadtrum instead of SPRD in menus
	- Changed TTY name to 'ttyS'
	- Moved uart_register_driver() to probe()
	- Added spinlock as needed
	- Removed register states saving and restoring in suspend() and resume()
