* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* serial: stm_serial: Add devicetree supportSascha Hauer2015-01-281-0/+9
| | | | | | | | | | This adds device tree support for the stm serial driver. This driver really is a AMBA primecell, so the amba-pl011 could be used. However, the current code tries to get the apb_pclk before the clocks are registered, so this does not work. Use the stm driver instead until a solution is found.

| | | | | | | | | | None of the driver make the difference between STDOUT and STDERR.

| | | | | | | | | | i.MX23 currently uses kHz as the unit for its clock handling and calculation to avoid overflows when calculation with the internal 480 MHz PLL and its fractional divider.
