davinci: DA830/OMAP-L137 EVM: use runtime detection for UI card
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() Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
