As part of this series, apart from patch containing changes to register TEGRA
USB PHY driver as platform driver, prepared below patches:
1. Re-arranging adding new DT properties.
2. Getting various params from DT properties added.
3. code clean up.
Venu Byravarasu (7):
ARM: tegra: finalize USB
register space. We can't assume the PHY1
driver is present, so the PHY3 driver will directly access those
registers.
3) The list of clocks required by the PHY was missing some required
entries.
This patch fixes the binding definition to resolve these issues.
Signed-off-by: Venu Byravarasu vbyravar
the driver has been updated to assume the new bindings.

As GPIO information is avail through DT, used it to get Tegra ULPI
reset GPIO number. Added a new member to tegra_usb_phy structure to
store this number.

Tegra USB host driver is using port instance number,
to handle some of the hardware issues on SOC e.g. reset PORT0
twice etc. As instance number based handling looks ugly,
making use of information passed through DT for achieving this.
