2017-02-20google/eve: Fix FPC supportDuncan Laurie
Currently UART0 GPIOs are being put into native mode during FSP-S stage, so have ramstage re-configure them back to regular GPIO mode. GPP_C8 does not seem to be functioning properly when routed to the APIC, possibly due to the UART0 being enabled even though it is unused, which is required because UART0 is PCI 1e.0 and so must be present for other 1e.x functions to be enumerated. Instead, use this pin as a GPIO interrupt so it will be routed through the GPIO controller at IRQ 14. GPP_C9 was inverted and was only working because the pin was being re-configured in FSP-S. Also export the reset gpio as a device property so it can be used by the kernel driver, which will stop it from complaining at boot. BUG=chrome-os-partner:61233 TEST=verify that the interrupt and device is functional in the OS Change-Id: Iaf9efbf50a13a981c6a9bbd507475777837e9c12 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18395 Tested-by: build bot (Jenkins) Reviewed-by: Furquan Shaikh <furquan@google.com>
2017-02-04google/eve: Set GPIO GPP_D22 highDuncan Laurie
GPIO GPP_D22 controls the I2S buffer for isolating the I2S signals when doing GPIO-driven I2S. This needs to be high by default so the DSP can drive these signals, instead of low where it is enabled for GPIO-driven I2S and the DSP cannot drive these signals.

On this board i2c3 bus is connected to the display TCON, but it is acting as the master when it has power so it can read from its own EEPROM on the bus. In order to prevent any possible issues in S0 make these pins input on the SOC. BUG=chrome-os-partner:58666 TEST=tested on eve board, but this bus was not used before so there is no visible change in behavior.
