a08b6d1141 - Add clk_set_source_freq field to struct ti_clock_dev so clock device
consumers can configure clock frequency
- Add ti_prcm_clk_set_source_freq wrapper for clk_set_source_freq
- Add am335x_clk_set_arm_disp_freq function to control pixel clock
   frequency for LCD and HDMI output. Both of them are sensitive
   to frequency skews and we need to get pixel clock matching requested
   frequency as close to possible

5b03aba6c8 Switch TI platform support code from using FreeBSD's custom-baked DTS
files to vendor-provided ones. It should make easier to adopt platform
code to new revisions of hardware and to use DTS overlays for various
Beaglebone extensions (shields/capes).

Original dts filenames were not changed, they're now wrappers over dts
files provided by TI. So make sure you update .dtb files on your
devices as part of kernel update

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3

On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt
on serial port in multiuser mode. Single user mode serial console
should work as-is

2566c5264a Add support to turn off Beaglebone with poweroff(8) or shutdown(8) -p.
To cut off the power we need to start the shutdown sequence by writing
the OFF bit on PMIC.

Once the PMIC is programmed the SoC needs to toggle the PMIC_PWR_ENABLE
pin when it is ready for the PMIC to cut off the power.  This is done by
triggering the ALARM2 interrupt on SoC RTC.

The RTC driver only works in power management mode which means it won't
provide any kind of time keeping functionality.  It only implements a way
to trigger the ALARM2 interrupt when requested.

855feb6867 Adds the ADC driver for TI AM3xxx SoC family.
The ADC has a 12bit resolution and its raw output can be read via sysctl(8)
interface.

The driver allows the setup of ADC clock, samples average and open delay
(the number of clock cycles to wait before start the conversion).

The TSC_ADC module is set in the general purpose mode (no touchscreen
support).

Tested on Beaglebone-black.

Written based on AM335x TRM.
