+ *
+ * This structure serves as a handle for the incremental construction of a
+ * tcw and associated tccb, tsb, data tidaw-list plus an optional interrogate
+ * tcw and associated data. The data structures are contained inside a single
+ * contiguous buffer provided by the user.
+ *
+ * The itcw construction functions take care of overall data integrity:
+ * - reset unused fields to zero
+ * - fill in required pointers
+ * - ensure required alignment for data structures
+ * - prevent data structures to cross 4k-byte boundary where required
+ * - calculate tccb-related length fields
+ * - optionally provide ready-made interrogate tcw and associated structures
+ *
+ * Restrictions apply to the itcws created with these construction functions:
+ * - tida only supported for data address, not for tccb
+ * - only contiguous tidaw-lists (no ttic)
+ * - total number of bytes required per itcw may not exceed 4k bytes
+ * - either read or write operation (may not work with r=0 and w=0)
+ *
+ * Example:
+ * struct itcw *itcw;
+ * void *buffer;
+ * size_t size;
+ *
+ * size = itcw_calc_size(1, 2, 0);
+ * buffer = kmalloc(size, GFP_DMA);
+ * if (!buffer)
+ * return -ENOMEM;
+ * itcw = itcw_init(buffer, size, ITCW_OP_READ, 1, 2, 0);
+ * if (IS_ERR(itcw))
+ * return PTR_ER(itcw);
+ * itcw_add_dcw(itcw, 0x2, 0, NULL, 0, 72);

- * Changelog:
- *
- * 22-Jul-2004 BJD Finished off device rewrite
- *
- * 21-Jul-2004 BJD Thanks to <herbet@13thfloor.at> for pointing out
- * problems with baud rate and loss of IR settings. Update
- * to add configuration via platform_device structure
- *
- * 28-Sep-2004 BJD Re-write for the following items
- * - S3C2410 and S3C2440 serial support
- * - Power Management support
- * - Fix console via IrDA devices
- * - SysReq (Herbert Pötzl)
- * - Break character handling (Herbert Pötzl)
- * - spin-lock initialisation (Dimitry Andric)
- * - added clock control
- * - updated init code to use platform_device info
- *
- * 06-Mar-2005 BJD Add s3c2440 fclk clock source
- *
- * 09-Mar-2005 BJD Add s3c2400 support
- *
- * 10-Mar-2005 LCVR Changed S3C2410_VA_UART to S3C24XX_VA_UART

-/* Note on 2440 fclk clock source handling
- *
- * Whilst it is possible to use the fclk as clock source, the method
- * of properly switching too/from this is currently un-implemented, so
- * whichever way is configured at startup is the one that will be used.
-*/
-
-/* Hote on 2410 error handling
- *
- * The s3c2410 manual has a love/hate affair with the contents of the
- * UERSTAT register in the UART blocks, and keeps marking some of the
- * error bits as reserved. Having checked with the s3c2410x01,
- * it copes with BREAKs properly, so I am happy to ignore the RESERVED
- * feature from the latter versions of the manual.
- *
- * If it becomes aparrent that latter versions of the 2410 remove these
- * bits, then action will have to be taken to differentiate the versions
- * and change the policy on BREAK
- *
