Changes since v1: - Addressed comments from Dmitry Torokhov. - Type of controller is cached in driver's private data and the function that determines the type of the controller for each keypad scan is removed. - pdata allocated during probe is explicitly freed after probe completes without any error. In case of exit from probe due a error, no explicit deallocation of pdata memory is performed and it is left to devres to handle that. - The generic code to translate KEY(x,y,code) is retained in the driver itself. I am unsure of a right common place for it. - Driver continues with the probe even if one or more gpio configuration fails. - Patch 1 that adds a new config option is still retained in this patchset. This patchset adds device tree support for samsung's keypad controller driver. First patch adds a new config option to be used by device tree enabled platforms for selecting the samsung's keypad controller driver. The second patch adds device tree support for the keypad driver.
