watchdog: w83627hf: Use helper functions to access superio registers

2013-11-18T20:34:19+00:00

Use helper functions named similar to other drivers to access
superio registers.

Request memory region only when needed, and use request_muxed_region().
This lets other devices (hwmon, gpio) use the same region.

watchdog: w83627hf: Enable watchdog device only if not already enabled

2013-11-18T20:34:13+00:00

There is no need to enable the watchdog device if it is already enabled.
Also, when enabling the watchdog device, only set the watchdog device
enable bit and do not touch other bits; depending on the chip type,
those bits may enable other functionality.

watchdog: w83627hf: Enable watchdog only once

2013-11-18T20:34:08+00:00

It is unnecessary to enable the logical device and WDT0 each time
the watchdog is accessed. Do it only once during initialization.

watchdog: omap_wdt: raw read and write endian fix

2013-11-17T18:42:38+00:00

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

watchdog: sirf: don't depend on dummy value of CLOCK_TICK_RATE

2013-11-17T18:42:31+00:00

As CSR SiRF is converted to multi platform CLOCK_TICK_RATE is a dummy
value that seems to match the right value is used.
(arch/arm/mach-prima2/include/mach/timex.h which defined CLOCK_TICK_RATE
to 1000000 was removed in commit cf82e0e (ARM: sirf: enable
multiplatform support); marco used the same file.)

To not depend on that dummy value use a local #define instead.

watchdog: pcwd_usb: overflow in usb_pcwd_send_command()

2013-11-17T18:42:18+00:00

We changed "buf" from being an array of 6 chars to being a pointer this
sizeof(buf) needs to be updated as well.

watchdog: rt2880_wdt: fix return value check in rt288x_wdt_probe()

2013-11-17T18:38:44+00:00

In case of error, the function devm_request_and_ioremap() returns NULL
pointer not ERR_PTR(). Fix it by using devm_ioremap_resource() instead
of devm_request_and_ioremap().
