Instead of doing the ioctl handling manually just use register a
watchdog_device and let the watchdog framework do the ioctl handling.This also removes the ltq_wdt_bootstatus_set typedef and replaces it
with a structure providing the chip specific functions pointer.
The watchdog_init_timeout() function is now used and the initial timeout
can be provided in device tree.
If the watchdog was already activated it will not be stopped any more,
but the settings from the driver will be used and the watchdog subsystem
will take care.Signed-off-by: Hauke Mehrtens

Some of the names of the bits were confusing to me.
Now the bits share the same prefix as the register they are set on.The LTQ_WDT_CR_PWL register (bits 26:25) is the pre warning limit and it
does not turn anything on. It has 4 possible divers 1/2, 1/4, 1/8 and
1/16, this drivers only uses 1/16.
The LTQ_WDT_CR_CLKDIV register bits(25:24) is only configuring a clock
divers and do not turn any thing on too, all possible values are valid
dividers.
Using the LTQ_WDT_SR prefix is also wrong these bits are used in the
LTQ_WDT_CR registers, SR is the status register which is read only.This uses GENMASK where it is a mask and it uses shifts when a value is
written to some bits.Signed-off-by: Hauke Mehrtens

This patch avoids accessing the function ltq_reset_cause() and directly
accesses the register given over the syscon interface. The syscon
interface will be implemented for the xway SoCs for the falcon SoCs the
ltq_reset_cause() function never worked, because a wrong offset was used.Signed-off-by: Hauke Mehrtens

I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.Either the device is enumerated and the driver already has a module
alias (e.g. PCI, USB etc.) that will get the right driver loaded
automatically.Or the device is not enumerated and loading its driver will lead to
more or less intrusive hardware poking. Such hardware poking should be
limited to a bare minimum, so the user should really decide which
drivers should be tried and in what order. Trying them all in
arbitrary order can't do any good.On top of that, loading that many drivers at once bloats the kernel
log. Also many drivers will stay loaded afterward, bloating the output
of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
loaded as a dependency) can't even be unloaded!If defining char-major-10-130 is needed then it should happen in
user-space.Signed-off-by: Jean Delvare

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.Signed-off-by: Thierry Reding

Data allocated with devm_ioremap or devm_ioremap_nocache should not be
freed using iounmap, because doing so causes a dangling pointer, and a
subsequent double free.The semantic match that finds this problem is as follows:
