hsu: driver for Medfield High Speed UART device
This is a PCI & UART driver, which suppors both PIO and DMA mode UART operation. It has 3 identical UART ports and one internal DMA controller. Current FW will export 4 pci devices for hsu: 3 uart ports and 1 dma controller, each has one IRQ line. And we need to discuss the device model, one PCI device covering whole HSU should be a better model, but there is a problem of how to export the 4 IRQs info Current driver set the highest baud rate to 2746800bps, which is easy to scale down to 115200/230400.... To suport higher baud rate, we need add special process, change DLAB/DLH/PS/DIV/MUL registers all together. 921600 is the highest baud rate that has been tested with Bluetooth modem connected to HSU port 0. Will test more when there is right BT firmware. Current version contains several work around for A0's Silicon bugs Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
