The README file for led_xec sample had several formatting issues
causing it to render very poorly.

@ -9,12 +9,16 @@ Overview
This sample allows to test the Microchip led-xec driver which uses the
breathing-blinking LED (BBLED) controllers. The SoC design is fixed
allowing each BBLED control over one specific GPIO.
MEC15xx and MEC172x:
BBLED controller 0 uses GPIO 0156.
BBLED controller 1 uses GPIO 0157.
BBLED controller 2 uses GPIO 0153.
MEC172x has a fourth instance of BBLED.
BBLED controller 3 uses GPIO 0035
- BBLED controller 0 uses GPIO 0156.
- BBLED controller 1 uses GPIO 0157.
- BBLED controller 2 uses GPIO 0153.
MEC172x has a fourth instance of BBLED:
- BBLED controller 3 uses GPIO 0035

EVB: mec172xevb_assy6906
BBLED0 GPIO 0156.
Connect GPIO 0156 to board LED4 by placing a wire from JP71-11 to J47-3.
Make sure there are no jumpers on JP54 1-2 and JP21 4-5
mec172xevb_assy6906 evaluation board
====================================
BBLED1 GPIO 0157.
Connect GPIO 0156 to board LED5 by placing a wire from JP71-12 to J48-3.
Make sure there are no jumpers on JP54 3-4 and JP21 16-17
- BBLED0: GPIO 0156.
- Connect GPIO 0156 to board LED4 by placing a wire from JP71-11 to J47-3.
- Make sure there are no jumpers on JP54 1-2 and JP21 4-5
BBLED2 GPIO 0153.
Connect GPIO 0153 to board LED7 by placing a wire from JP71-5 to JP146-5.
JP146-5 is connected to MEC172x VCI_OUT1 without a jumper. Force VCI_OUT1
high by forcing VCI_IN1 high: install jumper on J55 3-4 which pulls VCI_IN1
to the VBAT rail via a 100K pull-up. Requires VBAT power rail is connected
to VTR or some other power source.

BBLED3 GPIO 0035.
Connect GPIO 0035 to board LED7 by placing a wire from JP67-19 to JP146-1.
Make sure there is no jumper on JP79 17-18.
JP146-1 is connected to MEC172x VCI_OUT2 without a jumper. Force VCI_OUT2
high by forcing VCI_IN2 high: install a jumper on J55 5-6 which pulls VCI_IN2
to the VBAT rail via a 100K pull-up. Requires VBAT power rail is connected
to VTR or some other power source.
