Subject: [PATCH v2 1/2] staging: panel: fix lcd type
Date: Tue, 24 Mar 2015 14:56:32 +0530	[thread overview]
Message-ID: <1427189193-7984-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)

the lcd type as defined in the Kconfig is not matching in the code.
as a result the rs, rw and en pins were getting interchanged.
Kconfig defines the value of PANEL_LCD to be 1 if we select custom
configuration but in the code LCD_TYPE_CUSTOM is defined as 5.

my hardware is LCD_TYPE_CUSTOM, but the pins were assigned to it
as pins of LCD_TYPE_OLD, and it was not working.
Now values are corrected with referenece to the values defined in
Kconfig and it is working.
checked on JHD204A lcd with LCD_TYPE_CUSTOM configuration.
