Some driver is using this type of DT bindings for clock (more detail,
see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt).
sound_soc {
...
cpu {
clocks = <&xxx>;
...
};
codec {
clocks = <&xxx>;
...
};
};
Current driver in this case uses of_clk_get() for each node, but there
is no devm_of_clk_get() today.
OTOH, the problem of having devm_of_clk_get() is that it encourages the
use of of_clk_get() when clk_get() is more desirable.
Thus, this patch adds new devm_get_clk_from_chile() which explicitly
reads as get a clock from a child node of this device.
By this function, we can also use this type of DT bindings
sound_soc {
clocks = <&xxx>, <&xxx>;
clock-names = "cpu", "codec";
clock-ranges;
...
cpu {
...
};
codec {
...
};
};

The clk notifier symbols are hidden by COMMON_CLK. However on some
platforms HAVE_CLK might be set while COMMON_CLK not which leads to
compile test build errors like:
$ make.cross ARCH=sh
drivers/devfreq/tegra-devfreq.c: In function 'tegra_actmon_rate_notify_cb':
>> drivers/devfreq/tegra-devfreq.c:391:16: error: 'POST_RATE_CHANGE' undeclared (first use in this function)
if (action != POST_RATE_CHANGE)
^

>> drivers/devfreq/tegra-devfreq.c:654:8: error: implicit declaration of function 'clk_notifier_register' [-Werror=implicit-function-declaration]
err = clk_notifier_register(tegra->emc_clock, &tegra->rate_change_nb);
^
Export the macros and data type declarations outside of COMMON_CLK ifdef
and provide stubs to fix the compile testing.

1. change isp reset to "asynchronous system reset"
If some errors is happened, isp can not return to normal state
without "asynchronous system reset".
2. change the way of attach/detach iommu
As the modification of 1), isp will be reset by "asynchronous system reset"
when isp subdev is stop, so iommu is need to detach and reattach.
Now we detach/attach iommu not only when suspend/resume system, but also after isp is reset.
To handle the two cases together, we remove the function of detach/attach iommu
when suspend/resume system, add the function of attach iommu when first stream is opened
and detach iommu when last stream is closed.

There are still quite a few cases where a device might want
to get to a different node of the device-tree, obtain the
resources and map them.
We have of_iomap() and of_io_request_and_map() but they both
have shortcomings, such as not returning the size of the
resource found (which can be useful) and not being "managed".
This adds a devm_of_iomap() that provides all of these and
should probably replace uses of the above in most drivers.
