[PATCH 0/5] ARM: Tegra: Harmony: Enable audio driver

[PATCH 0/5] ARM: Tegra: Harmony: Enable audio driver

[Stephen Warren]

This patchset enables the audio driver for Tegra Harmony.

Important notes:
* This series is based on Olof's recently posted boards-for-next branch.
  Some patches won't apply without that being in first.
* The final patch in the series depends on header adds/edits that are not
  in Tegra's for-next branch

See notes in the individual patches for further details.

Stephen Warren (5):
  ARM: Tegra: Add devices.c entries for audio
  ARM: Tegra: Rename I2S clocks to match driver name
  ARM: Tegra: Rename clk_dev1/2 to cdev1/2
  ARM: Tegra: Create defines for GPIO names
  ARM: Tegra: Enable Harmony audio support

[PATCH 2/5] ARM: Tegra: Rename I2S clocks to match driver name

[Stephen Warren]

The driver is tegra-i2s not just i2s. Rename the clocks to match, so that
clk_get_sys can look up by driver name.

[PATCH 3/5] ARM: Tegra: Rename clk_dev1/2 to cdev1/2

[Stephen Warren]

The ASoC machine driver was written assuming my previous patch to add
complete support for these clocks, which named them cdev1/2. Rename
the clocks to match that, to avoid churn in the ASoC driver.

This rename also makes the clocks more consistent with other Tegra
clocks irrespective of any of that.

This ensures they're kept in sync between platform_data definitions and
the GPIO table initialization.

Can you name these for what they are used for (if they have a single use)?
i.e. TEGRA_GPIO_EMMC_CD instead of TEGRA_GPIO_SD2_CD

Are you looking for correlation with the schematics, or something else;
my interpretation is that the names in the patch already appear to describe
what the signals are used for.

In particular, in your example, you wrote "EMMC" rather than "SD2". I'm not
sure where the name "EMMC" comes from, nor why there's no number in the name
"EMMC".

For reference, the schematics for these two boards use the following signal
names:

Harmony:
SDIO2_CD, SDIO2_WP, EN_VDDIO_SD
HSMMC_CD, HSMMC_WP, EN_VDDIO_SDMMC

Seaboard:
SDIO32_CD, SDIO3_WP, EN_VDDIO_SD

Would those be OK?

Thanks.

I meant use the name of the device they are connected to (if there is
one).  By EMMC I meant the embedded MMC storage device.  The gpio is
not notable because it is used by the SDIO driver for port 2, it is
notable because it is connected to the EMMC chip or the wifi chip or a
card slot.

The GPIOs currently in the code are for SD slots/connectors; we don't have
any GPIO definitions for any internal MMC memory, or WiFi chips.

I guess the numbering could be changed; 2 vs. 4 don't very obviously map to
the slots on the board for the user, yet the only thing better I can think
of would be the connector numbers on the silkscreen?

If they are just general-purpose slots, the existing naming is fine.

[PATCH 5/5] ARM: Tegra: Enable Harmony audio support

[Stephen Warren]

* Set up platform data required by I2C, and ASoC machine & codec drivers.
* Enable required GPIO pins as GPIOs.
* Initialize audio-related clocks.
* Correctly configure pinmux for audio-related GPIOs.

NOTE: This patch will not apply until Olof's recently posted
boards-for-next branch is merged.

NOTE: This patch will not apply until the following two commits are
present in Tegra for-next:

Mark said he'd be OK with this being cherry-picked into the Tegra tree.

Ben hasn't been asked whether a cherry-pick is OK. We could ask, or simply
wait for the merge window to be open, Linus' tree to pick this change up,
Tegra for-next to be rebased on Linus' tree, and then apply the patch below.

Note: I manually tested cherry-picking both those changes into Tegra for-next,
merging Olof's branch, and applying this patch series. The build succeeded,
and Harmony booted to a shell prompt.

Sure. But then, wouldn't it make sense to also rename all the TEGRA_GPIO_*
below too?

True, but no point in adding churn.  Those can be cleaned up later.  I
just want it to be clear that the numbering of gpios above
TEGRA_NR_GPIOS is specific to the board, so the next board author
doesn't get it wrong.

Re: [PATCH 5/5] ARM: Tegra: Enable Harmony audio support

[Olof Johansson]

Stephen,

Since this depends on i2c, and registers one of the adapters to do it,
we should just get the adapters registered separately (all of them)
before this. I was holding off that part of board code since the i2c
driver went up that maintainer path instead, but if Colin pulls it
into tegra for-next, then I'll go ahead with those peices as well.

I'll pick up the board-side patches from this series (1, 4, 5), and
Colin will take the core patches (2, 3).

The above assumes that wm8903 is the GPIO controller that gets
allocated the numbers right after native tegra gpio. That might not be
the case on all boards, since the TPS PMIC has some as well, I
believe.

Does it need a hardcoded GPIO base, or can it use the dynamic one
(i.e. use -1 here)? I don't even see any reference to gpio_base in the
driver...

The GPIO numbers above TEGRA_NR_GPIOS are allocated by the board, and
this is in board-harmony.h, so I think its OK.

I assume that is in the ASoC tree.  The platform data in tegra
for-next does not include a gpio_base entry.

Hi,

On second thought, it's probably even preferred, since otherwise the
dynamic allocation can mess up the static ones.

Yeah, I only looked at the current driver in .37, my bad.

The Seaboard equivalent of this that I wrote for ChromeOS is:

#define TPS_GPIO_BASE			TEGRA_NR_GPIOS

#define TPS_GPIO_WWAN_PWR		(TPS_GPIO_BASE + 2)

#define GPIO_WM8903(_x_)		(TPS_GPIO_BASE + 4 + (_x_))

Which takes into account other devices.

Yes, gpio_base is added to that tree.

-1 would probably work. But then, I have no idea how to find out what base
was assigned to the WM8903, in order to initialize the ASoC machine driver's
platform_data...

Yeah, like I said in a separate reply, keeping it the way it is will
work out for the best.

I'll merge the i2c-tegra branch into for-next (assuming Ben doesn't
object to it), and you can put all the i2c devices in your pull
request.  That way we can get everything except this patch into the
first pull request to Linus, and just put this patch into a second
pull request once the ASoC branch is merged.

OK, so just so I'm clear:

Patches 1..4 are all going in as-is.

I should re-post patch 5 once the merge window is open, having rebased
it on Olof's i2c registration changes, and
s/GPIO_WM8903/HARMONY_GPIO_WM8903/. Or, should I repost as soon as Olof
has updated his branch with the I2C changes, and you'll just hold off
applying it until the merge window?

Thanks.

How big would the delta be between a patch that would apply (and work)
with current .38-rc wm8903 platform data? If it's just the GPIO base,
we can merge everything but that and just do the small change late in
the merge window.

And yeah, please repost after the i2c stuff is in my branch, I'll
stage it accordingly.

Once the I2C tree is merged, the only thing needed to make my patch
apply immediately is to remove the gpio_base assignment. I can split
that into a separate patch and post a series if that helps.
