These are the changes I proposed in two separate patchsets #([1], [2]) rebased to 3.19 as well as new changes for little bugs I noticed while preparing this patchset. 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 --> remove 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. --> Fix all of these.
