r306530:
Declare a module for evdev and add dependency to ukbd(4) and ums(4)
Prepare for making evdev a module. "Pure" evdev device drivers (like
touchscreen) and evdev itself can be built as a modules regardless of
"options EVDEV" in kernel config. So if people does not require evdev
functionality in hybrid drivers like ums and ukbd they can, for instance,
kldload evdev and utouchscreen to run FreeBSD in kiosk mode.
r306531:
Add dependency to evdev module (if required)
r306532:
Add dependency to evdev module
r306579:
Modularize evdev
- Convert "options EVDEV" to "device evdev" and "device uinput", add
modules for both new devices. They are isolated subsystems and do not
require any compile-time changes to general kernel subsytems
- For hybrid drivers that have evdev as an optional way to deliver input
events add option EVDEV_SUPPORT. Update all existing hybrid drivers
to use it instead of EVDEV
- Remove no-op DECLARE_MODULE in evdev, it's not required, MODULE_VERSION
is enough
- Add evdev module dependency to uinput

r305708:
Add evdev support to TI ADC/touchscreen driver
Add generic evdev support to touchscreen part of ti_adc: two absolute
coordinates + button touch to indicate pen position. Pressure value
reporting is not implemented yet.
Tested on: Beaglebone Black + 4DCAPE-43T + tslib
r305719:
Cleanup evdev support for TI ADC/TS
- evdev_set_methods call is not required if actual methods are no-ops
- evdev_set_serial is also optional if there is no meaningful input device
identifier
- evdev_set_id on the other hand is mandatory, so set virtual bus with
dummy vendor/product/version

Configure the analog input 7 which, on BBB, is connected to the 3V3B rail
through a voltage divisor (R163 and R164 on page 4 of BBB schematic).
Add a note about this on ti_adc(4) man page. The ti_adc(4) man page will
first appear on 10.1-RELEASE.
MFC after: 1 week

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.
