If anyone has any objections, please let me know. ------------------ From: Sudip Mukherjee commit 2c20d92dad5db6440cfa88d811b69fd605240ce4 upstream. 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.
