Hi,
I am trying to define the mux settings for keypad on the omap3evm.
I had a few queries on the same.
1) Is it enough to me this change:
static struct omap_board_mux board_mux[] __initdata = {
+
+ /* SYS_NIRQ */
+ OMAP3_MUX(SYS_NIRQ, OMAP_MUX_MODE0 | OMAP_PIN_INPUT_PULLUP |
+ OMAP_PIN_OFF_INPUT_PULLUP),
+
{ .reg_offset = OMAP_MUX_TERMINATOR },
2) Or should I follow with this (in the evm init code):
+ omap_mux_init_signal("af26", OMAP_PIN_INPUT_PULLUP |
+ OMAP_PIN_OFF_INPUT_PULLUP);
3) OR is this a better(or worse)
static struct omap_board_mux board_mux[] __initdata = {
+
+ /* SYS_NIRQ */
+ OMAP3_MUX(SYS_NIRQ, OMAP_MUX_MODE0),
+
{ .reg_offset = OMAP_MUX_TERMINATOR },
..and later
+ omap_mux_init_signal("af26", OMAP_PIN_INPUT_PULLUP |
+ OMAP_PIN_OFF_INPUT_PULLUP);
Best regards,
Sanjeev
