Thanks. Patches are added to my git tree at

 preparing this patch series as well as changes introduced via comments.

 1. DEBUG was undefined in source code -- remove offending lines
 2. add capability to have busses as children of the GPMC and multiple
devices on a bus. See [2] for an example DTS syntax.
 3. debug output was unaligned -- align it
 4. output for copy-pasting to DTS had erroneous timing outputs and
made it hard to copy-paste -- correct timing values, add comments
as DTS comments.
 5. WAITMONITORINGTIME is expressed as GPMC_CLK cycles for all accesses.
GPMCFCLKDIVIDER is used as a divider, so it must always be programmed.
 6. GPMCFCLKDIVIDER is calculated according to WAITMONITORINGTIME for
asynchronous accesses inside the driver -- asynchronous accesses now
completely decoupled from gpmc,sync-clk-ps.
 7. WAITMONITORINGTIME was being programmed/shown in GPMC_FCLK cycles instead
of GPMC_CLK cycles -- add clock domain information where necessary.
 8. Calculated values for WAITMONITORINGTIME and CLKACTIVATIONTIME that were
outside the defined range would not raise an error.
DEVICESIZE, ATTACHEDDEVICEPAGELENGTH, WAITMONITORINGTIME and
CLKACTIVATIONTIME would not be marked as incorrect on DTS output.
