The platform driver for the TLL component of the OMAP USB host controller
is implemented. Depending on the TLL hardware revision , the TLL channels
are configured. The USB HS core driver uses this driver through exported
APIs from the TLL platform driver.
usb_tll_enable and usb_tll_disble are the exported APIs of the USB TLL
platform driver.

Before the AB8500 had its own IRQ domain, the IRQ handler would take
the fired local IRQ (hwirq) and add it to the irq_base to convert it
to an IRQ number which Linux would understand (virq). However, the
IRQ base is not always used anymore since we can make use of Linear
domains. It's better to use the AB8500 hwirq -> virq mapping helper
function to convert them instead. That's what we do here.

The MAX8907 is an I2C-based power-management IC containing voltage
regulators, a reset controller, a real-time clock, and a touch-screen
controller.

The original driver was written by:
* Gyungoh Yoo <jack.yoo@maxim-ic.com>

Various fixes and enhancements by:
* Jin Park <jinyoungp@nvidia.com>
* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>

During upstreaming, I (swarren):
* Converted to regmap.
* Converted to regmap-irq.
* Allowed probing from device tree.
* Renamed from max8907c->max8907, since the driver covers at least the
  C and B revisions.
* General cleanup.
