Version 1.0.6: fix GPIO regression, support PocketBeagle, support 4.14 kernel PWM

Version 1.0.6

• Currently recommended image: Debian 9.2 "Stretch" iot (2017-10-29)
  • Install Linux kernel 4.14.x to enable non-root control of GPIO and PWM (commit)

Features:

• Add support for Linux 4.14 kernel including new "udev" style for PWM entries in /sys
• Fix GPIO regression due to BeagleBone Blue LED support #178
• Add support for the PocketBeagle #172

shortlog:

• Drew Fustini (39):

  • Add -Wno-unit_address_vs_reg to avoid dtc warning
  • check if board is BeagleBone Blue or PocketBeagle
  • check if BeagleBone Blue before accessing non-standard LEDs
  • Add test for GPIO regression #178
  • change syslog mask level to DEBUG
  • add "Adafruit_BBIO" to syslog()
  • update test for issue #178
  • remove polarity "hack" for PWM #170
  • move pwm_set_polarity() after period is set
  • add test for issue #170
  • only check kernel overlays if u-boot overlays are not being used
  • Attempt to use udev ecap path for pwm path
  • add test script for all BeagleBone PWM outputs
  • update PWM test for 4.14 kernel udev paths
  • minor change to pwm debug logging
  • sleep to avoid udev race condition #185

• Mark A. Yoder (1):

  • Added BAT25, BAT50, BAT75, BAT100 and WIFI LEDs

• Peter Lawler (1):

  • Missing CR/LF

• Robert Nelson (10):

  • source/common.c: add initial PocketBeagle values
  • source/common.c: PocketBeagle, no slots file, everything built-in
  • source/common.c: PocketBeagle, no slots file disable here too
  • source/c_pwm.c: HACK: U-Boot pre-setup everything, dont search for specific overlay
  • source/c_pwm.c: HACK: PocketBeagle: v4.14.x
  • source/c_pwm.c: debug pwm_path/pwm_path_udev
  • source/c_pwm.c: pwm: add support for pwmchipX/pwm-X:Y syntax
  • source/c_pwm.c: disable pwm_set_polarity (broken in v4.9.x/v4.14.x)
  • source/common.c: Blue Fix GP0_3 id
  • source/common.c: PocketBeagle Fix P2.24
