Subject: eGalax touchscreen regression

Hi Dmitry,

in the below commit

commit ae495e844a77344fdaedbb2ad97d925d096e9f0d
Author: Hui Wang <jason77.wang@...il.com>

    Input: egalax_ts - get gpio from devicetree
    
    The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework
    and don't support this API anymore.
    
    The i.MX6q sabrelite platform equips an egalax touchscreen controller,
    and this platform already transfered to GENERIC_GPIO framework, to
    support this driver, we use a more generic way to get gpio.
    
    Add a return value checking for waking up the controller in the probe
    function, this guarantee only a workable device can pass init.
    
    [dmitry.torokhov@...il.com: Make driver depend on CONFIG_OF as it is
     now required.]

the eGalax driver now requires OF. For us this is a regression because
we do not have OF: https://bugs.tizen.org/jira/browse/TIVI-740
