ARM: dt: tegra: cardhu: split dts file for support multiple board versions 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. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>

ARM: tegra: cardhu: add dt entry for fixed regulators 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.
