2010-12-16gpio: Add Multi-Function-Pin configuration driver for Marvell SoCsPrafulla Wadaskar
Most of the Marvell SoCs has Multi Function Pin (MFP) configuration registers For ex. ARMADA100. These registers are programmed to expose the specific functionality associated with respective SoC Pins This driver provides configuration APIs, using them, configuration need to be done in board specific code for ex- following code configures MFPs 107 and 108 for UART_TX/RX functionality int board_early_init_f(void) { u32 mfp_cfg[] = { /* Console on UART1 */ MFP107_UART1_RXD, MFP108_UART1_TXD, MFP_EOC /*End of configureation*/ }; /* configure MFP's */ mfp_config(mfp_cfg); return 0; } Signed-off-by: Prafulla Wadaskar <prafulla@marvell.com>
