Well this is still missing the gpio_request parts that are needed
for the serial port to wake. I have not added that as it currently
means we also get a gpio interrupt for every rx.
I'll do more patches to deal with the gpio parts later on.
The idle values are only needed for rx pins:
+static struct omap_device_pad serial2_pads[] __initdata = {
+ {
+ .name = "uart3_rx_irrx.uart3_rx_irrx",
+ .flags = OMAP_DEVICE_PAD_REMUX | OMAP_DEVICE_PAD_WAKEUP,
+ .enable = OMAP_MUX_MODE0,
+ .idle = OMAP_MUX_MODE3 /* Mux as GPIO for idle */
+ },
+ { .name = "uart3_tx_irtx.uart3_tx_irtx", .enable = OMAP_MUX_MODE0, },
+};
For the others, nothing is done dynamically.
Regards,
Tony
