[PATCH v2 0/3] ARM: dt: tegra: cardhu: add entry for regulators

[PATCH v2 0/3] ARM: dt: tegra: cardhu: add entry for regulators

[Laxman Dewangan]

This patch series add the PMIC and fixed regulators for 
cardhu board. There is multiple versions of cardhu baord named
as A01, A02, A03..and so on. Cardhu A01 and A03 are not supported.
Cardhu A02 and A04 have different sets of GPIO for regualtors.
The cardhu A04 is compatible for A05, A06 and A07 in GPIOs.
This patch series split the cardhu dts file to cardhu-a02 and 
carchu-a04 and then add entry for different fixed regualtors.

In patch 1, it enabled the PMIC tps65910 which is main pmu for 
the cardhu.
In Patch 2, split the cardhu support for cardhu-a02 and cardhu-a04.
In Patch 3, add different regulators.

Changes from V1-->V2:
- Remove the vdd_sdmmc1 regulator registration.
- Fix the pex_hvdd_3v3 regulator registration.
- Set panel regulator to be always on.
- Add i2c eeprom address in board-identification paragraph.

[Laxman Dewangan]

Tegra30 based platform "cardhu" have the power management

Adding DT entry for this device.
Data are chosen from downstream kernel and making the
voltage output as require by default for device to
operate.
The default interrupt line is HIGH from PMIC device and so
inverting the interrupt detection line of PMU interrupt
through configuring PMC.
In this patch, do not registering LDO5 because the input
supply for this rail is different for different version of
cardhu i..e A02 and A04. The registration will be done once
the dts file for cardhu A02 and A04 are added in follow on
patches.

[PATCH v2 2/3] ARM: dt: tegra: cardhu: split dts file for support multiple board versions

[Laxman Dewangan]

There is multiple version of cardhu starting from A01 to A07.
Cardhu A01 and A03 are not supported. Cardhu A02 will have
different sets of GPIOs for fixed regulator compare to
cardhu A04. The Cardhu A05, A06, A07 are compatibe with A04.
Based on cardhu version, the related dts file need to be chosen
like for cardhu A02, use tegra30-cardhu-a02.dts, cardhu A04 and
more, use tegra30-cardhu-a04.dts.
This patch create the DTS file A02 and A04 and convert tegra30-cardhu.dts
as dts include file.

[PATCH v2 3/3] ARM: tegra: cardhu: add dt entry for fixed regulators

[Laxman Dewangan]

Cadhu have multiple power rails which are controlled by
GPIOs. Add support of these power rail control through
fixed regulators. Add entry for all fixed regulators for
cardhu-a02 and a04.
The details are taken from downstream kernel.

Some points on this change are:

* Add the tps65910-LDO5 entry and make it always ON
 to supply power to SDMMC. Once the sd driver support
 regulator handling, this flag will be remove.

* Dropping registration of rail vdd_sdmmc1 as the gpio
  is used by sdhci power-gpio. This need to fix in
  sdhci driver and then need to add the registration
  mechanism. Just removing power-gpio and adding fixed
  regulator with this gpio is causing the sd  access to
  fail because first probe call of this regulator fails
  due to non-available of parent and so it calls
  gpio_free() which disable the pins in gpio mode make
  pin output to LOW causes power to OFF. In probe retry,
  it got success and it powered-on but it again need to
  do again numeration of card here.
