These patches add the support for Qualcomm IPQ4019 ASoC
with the ALSA based audio drivers. The patches are broken
1. Device Tree support
2. Audio clock driver support
3. TLMM / Pinctrl support
4. ALSA based audio drivers

This is *far* too big to be a single patch. Please at the very least
split this up into one patch per driver, look at the git history of
other drivers for examples of splitting things up.

You need to completely rework how you're posting this so it can be
reviewed, probably splitting it into separate patch serieses - please
see SubmittingPatches for an overview of what people are expecting, and
as I said in reply to one of the patches looking at git can also be
helpful. I'd suggest sending the drivers for each subsystem as a
separate patch series, there will be some interdependency in terms of
getting things running but not in terms of getting the patches applied.

I would recommend reducing this to "i2s_rx", "i2s_tx", "spdif_rx"
and "spdif_tx", as this will make the dts cleaner.

You'll also need to add all of these to the
Documentation/devicetree/bindings/pinctrl/qcom,ipq4019-pinctrl.txt
I was also going to suggest just using qca_i2s and having a single function, but
it seems like there is at least 1 pin that supports more than one i2s mode.

Andy

I'd expect something else in here like phandle links to sub blocks. This
alone just for purposes of instantiating a driver is not acceptible.

Just i2s at ... Though 0 here is not valid without a reg property. There's
no registers?

Lowercase hex only please. Also, just put the registers in the

Please preface all the sources with P_ so we know they're
"parents".

You don't have to call qcom_cc_map() and qcom_cc_really_probe()
if you don't need to do anything with the mapping in this probe.
Just call qcom_cc_probe().

So a ton of stuff is duplicated. I don't even want to read it
because the same rcg code is copied a few times and then some
modifications are made and special cases are made in generic code
for SoC specific things.

To: linux-arm-kernel
From: Jaiganesh Narayanan <njaigane@codeaurora.org>
These patches add the support for Qualcomm IPQ4019 ASoC
with the ALSA based audio drivers. The patches are broken
1. Device Tree support
2. Audio clock driver support
3. TLMM / Pinctrl support
4. ALSA audio drivers

qcom: ipq4019: Add ipq4019 ASoC device tree changes
qcom: ipq4019: ASoC clock driver support
qcom: ipq4019: ASoC tlmm/pinctrl support
qcom: ipq4019: Add ASoC driver modules
