Most machine classes want some way to register a block of clk_lookup structures, and most do it by implementing a clks_register() type function which walks an array, or by open-coding a loop. Consolidate all this into clkdev_add_table().

This reorganizes the vic.c code in anticipation of a second patch to use struct vic_device as the data stored in set_irq_chip_data(). The code now has the following flow: 1) struct vic_device definition, static variables, and to_vic() moved to the start of the code. 2) common code (vic_init2) 3) vic power management callbacks 4) vic power management initialization/registration 5) irq_chip callbacks 6) vendor specific vic initialization 7) vic initialization In addition the typo vik_init_st is fixed (vic_init_st). There is no functional change with this patch.

The PrimeCell Vectored Interrupt Controller offers a way to trigger any interrupt through software. This is a useful tool for developing, but such software interrupt can only be acked by writing a bit in the "software clear" register, or the handler will loop forever.

Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going.

If a machine class has a custom __virt_to_bus() implementation then it must provide a __arch_page_to_dma() implementation as well which is _not_ based on page_address() to support highmem. This patch fixes existing __arch_page_to_dma() and provide a default implementation otherwise. The default implementation for highmem is based on __pfn_to_bus() which is defined only when no custom __virt_to_bus() is provided by the machine class. That leaves only ebsa110 and footbridge which cannot support highmem until they provide their own __arch_page_to_dma() implementation. But highmem support on those legacy platforms with limited memory is certainly not a priority. Signed-off-by: NNicolas Pitre <nico@marvell.com>

The old matching algorithm was too fuzzy, causing false positives. For example, when asked for device D connection C1 and we only find device D connection C2, we return that as a valid match despite the connection names being different. Change the algorithm such that: An entry with a NULL ID is assumed to be a wildcard. If an entry has a device ID, it must match If an entry has a connection ID, it must match However, we maintain the order of precidence while still only doing a single pass over all entries: dev+con > dev only > con only.
