include: adds interface description for ili9341
...
This adds the description of the generic interface to communicate with
the ili9341 lcd single chip driver used by any displays.
The interface have to be implemented by the platform specific subdriver.
The following functions must be exported:
-select
Select the spi device before starting an operations.
-deselect
Deselect the spi device after operations finished and if the device was
selected before.
-sendcmd
Send any command to the ili9341 display driver.
-sendparam
Send any parameter corresponding to the ili9341 display driver.
-recvparam
Receive any parameter from the ili9341 display driver. This is only possible
for the read commands supported by the ili9341.
-sendgram
Send pixel data to the gram of the display. This i similar to the function
sendparam, but pixel data operations needs another handling of how to send the
data to the display.
-recvgram
Receive pixel data to the gram of the display. This i similar to the function
recvparam, but pixel data operations needs another handling of how to receive
the data from the display.
-backlight
Change the backlight level of the display.
