    davinci: DA830/OMAP-L137 EVM: use runtime detection for UI card · 1dca29d8
    Sekhar Nori authored
    This patch supports runtime detection of DA830 UI card and
    eliminates the need for DA830_UI config option. Successful
    probe of GPIO expander present on the UI card is used to
    detect its presence. For this reason, GPIO_PCF857X is auto-
    selected when DA830 EVM is configured. In case the UI card
    is absent, the probe fails in reasonable time.
    
    As a side effect this patch also gets rid of the voilation
    of Documentation/SubmittingPatches section 2.2 in function
    da830_evm_ui_expander_setup()
