Input GPIO changes can generate interrupts, but we need kind of ACK for them by changing IRQ polarity. This is required to stop hardware from keep generating interrupts and generate another one on the next GPIO state change. This code allows using GPIOs with standard interrupts and add for example GPIO buttons support. Signed-off-by:

we want the device tree to be unflattened into non init memory so it can be accessed later by, for example, a probing function of a driver module. Signed-off-by:

The defaults are not always applicable and it makes it hard for the bootloader to override them. By removing it we give the bootloader full control over what command line parameters to pass. Without this change we will need to modify the built-in dtb to add bootloader cmd line parameters or do some work to append them after we unflatten the device tree. Sead3 is a development board, that's why we want to be able to change boot parameters on the fly from the bootloader. Signed-off-by:

This patch switches Malta from using the MIPS implementation of early printk with Malta's prom_putchar to using the generic 8250_early implementation. This offers a couple of advantages: - We duplicate less generic code. - The UART can be initialised rather than being reliant upon inheriting a valid setup from the bootloader. The Malta console_config function is extended to initialise the early console if no earlycon= kernel parameter is provided, inheriting the modetty0 bootloader environment if present and falling back to a default 38400n8r setup if not. This matches the behaviour used for the regular console= parameter. Signed-off-by: -

This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ pin of the PIIX4 and to enable that interrupt. The kernel depends upon the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but previously would not configure it, instead relying upon the bootloader having done so. If that is not the case then the typical result is that the system appears to hang once it reaches userland as no output is displayed on the UART. Signed-off-by:

The RTC is used on Malta to estimate the clock frequency of the CPU & optionally the GIC. However the kernel previously did not initialise the RTC, instead relying upon the bootloader having done so. In order to minimise dependencies which the kernel has upon the bootloader this patch causes the kernel to initialise the RTC itself prior to making use of it. Signed-off-by:

The boot hangs early on EBH5600 board when octeon_fdt_pip_iface() is trying enumerate a non-existant interface. The actual hang happens in cvmx_helper_interface_get_mode(): mode.u64 = cvmx_read_csr(CVMX_GMXX_INF_MODE(interface)); when interface == 4. We can avoid this situation by first checking that the interface exists in the DTB. Signed-off-by:
