- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Make the noop clock successfully do nothing, because doing nothing and
returning an error status (which the NULL method pointers caused) isn't
nearly as useful.

Define the uart clocks so that they can be en/disabled at runtime.

Make the standard sdhci(4) driver work for the TI OMAP family SoCs.
The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.

This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.

This initial incarnation lacks DMA support (coming soon). Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.

Initialisation routines for the mailbox, spinlock and PRU-ICSS clocks.

Add IDs for TPS65217C and TPS65217D

- Add USBSS driver for AM335x SoC. Driver is a wrapper around Mentors Graphic
USB OTG core.

Add support for ePWM submodule of PWMSS

ePWM is controlled by sysctl nodes dev.am335x_pwm.N.period,
dev.am335x_pwm.N.dutyA and dev.am335x_pwm.N.dutyB that controls
PWM period and duty cycles for channels A and B respectively.

Period and duty cycle are measured in clock ticks. Default
clock frequency for AM335x PWM subsystem is 100MHz

- Request non-cached memory for framebuffer
- Properly probe/initialize syscons

AM335x LCD controller driver with syscons support

Limitations:
- Raster mode only
- 24 and 32 bpp only

Add PWM module driver for AM335x. Only eCAS subsystem is supported

Export function to configure eCAS submodule from another drivers.
It's used to control LCD panel backlight on AM335x EVM.

Add SCM registers definitions for AM335x platform

Add clock definitions for LCD controller and PWM module

MFcalloutng:
Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.

Fix case for some signal names.
