[PATCH] Separate out 3430 LCD panel support from 2430 file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Iqbal Shareef <iqbal@xxxxxx>

Separate out 3430 LCD panel support from 2430 SDP.

Currently the support for the LCD on 3430SDP is added in the lcd_2430sdp.c
file. This patch separates it out to a new file.
