The pinctrl driver initialized the register offsets for the pins

Add option to use with watchdog timers which are always enabled
in hardware, i.e. there is no way to enable/disable it via GPIO pin.
The driver will start pinging WDT immediately upon loading

Hi all,
This series introduces a bit of clean-up (reduce magic numbers) and
new features for the VT8500 serial driver.
Firstly, in a new generation of WonderMedia SoC's the UART module
changed slightly, and now requires one more bit to be set in its
line control register to function properly.
Current code relies on the UART clock pre-divisor to be already
configured in the baud rate register. Calculate it in the driver
and set explicitly instead, also return the real effective baud
rate, which is generally slightly different from the requested value.
While at this, also ensure that
This adds simple polling functions for single-character transmit
and receive, as used by kgdb.

Newer WonderMedia chips introduced another flag in the UART line control
register, which controls whether RTS/CTS signalling should be handled in
the driver or by the hardware itself.
This patch ensures that the kernel can control RTS/CTS (including
disabling it altogether) by forcing this flag

Hi every one,
This set of patches fix a segmentation fault happening when kexec-ing

While the previous kernel shuts down, the tcb_clksrc driver leaves its
interruptions unmasked. When the new kernel initiliazes any tclib making use of
a TC block,
Move resource retrieval from atmel_tc_alloc to tc_probe to avoid lately
reporting resource related issues when a TC block user request a TC block.
Moreover, resources retrieval are usually done in the probe function,
thus moving them add some consistency with other drivers.
Initialization is
Shutdown properly the timer counter block by masking interruptions. Otherwise,
a segmentation may happen when kexec-ing a new kernel (see backtrace below).
An interruption may happen before the handler is set, leading to a kernel
segmentation fault.
Furthermore, we make sure the interruptions are
The clock is not unprepared in case of the request IRQ fails.
