Can I do the same for:

	if (of_property_read_bool(np, "phy-clk-valid"))
                pdata->check_phy_clk_valid = 1;
	else
                pdata->check_phy_clk_valid = 0;

The type is not bool, but:

include/linux/fsl_devices.h:    unsigned        check_phy_clk_valid:1;

thanks,
julia

The type doesn't even matter, does it? Any bool->int conversion should
result in 0/1.

Applied "ASoC: use of_property_read_bool" to the asoc tree

[Mark Brown]

The patch

   ASoC: use of_property_read_bool

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

According to the binding, "qalloc-by-id" _is_ a boolean property, so
this one really does deserve to be of_property_read_bool()...

...whereas "accumulator" must have a value, so this isn't technically
appropriate. In general, most of these "if the property exists, read the
property and do stuff" checks are probably a sign of code that could be
simplified by refactoring the "do stuff" step to just specifically
handle the "read the property" step returning -EINVAL when it's not present.

Thanks for the very helpful feedback.  I will rethink the patch set in
light of this information.
