Subject: [PATCH 1045/1085] overlays: README: Sort the dtparam names
|
||
|
|
|
||
|
|
There are enough dtparams now that not having them in alphabetical
|
||
|
|
order makes them hard to find.

N.B. It is recommended to only enable those interfaces that are needed.
|

|
|
Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
|

|
|
interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
