      [POWERPC] qe: miscellaneous code improvements and fixes to the QE library · 6b0b594b
      Timur Tabi authored
      
      
      This patch makes numerous miscellaneous code improvements to the QE library.
      
      1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type()
         (every caller of ucc_init_guemr() also calls ucc_set_type()).  Modify all
         callers of ucc_set_type() accordingly.
      
      2. Remove the unused enum ucc_pram_initial_offset.
      
      3. Refactor qe_setbrg(), also implement work-around for errata QE_General4.
      
      4. Several printk() calls were missing the terminating \n.
      
      5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where
         appropriate.
      
      6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed
         with the wrong value.
      
      7. Add the protocol type to struct us_info and updated ucc_slow_init() to
         use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED.
      
      8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx()
      
      9. Add several macros in qe.h (mostly for slow UCC support, but also to
         standardize some naming convention) and remove several unused macros.
      
      10. Update ucc_geth.c to use the new macros.
      
      11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol
          to use when initializing the UCC in ucc_slow_init().
      
      12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since
          these are the real names of the registers.
      
      13. Use the setbits, clrbits, and clrsetbits where appropriate.
      
      14. Refactor ucc_set_qe_mux_rxtx().
      
      15. Remove all instances of 'volatile'.
      
      16. Simplify get_cmxucr_reg();
      
      17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[].
      
      18. Updated struct ucc_geth because struct ucc_fast is not padded any more.

      [POWERPC] Add QUICC Engine (QE) infrastructure · 98658538
      Li Yang authored
      
      
      Add QUICC Engine (QE) configuration, header files, and
      QE management and library code that are used by QE devices
      drivers.
      
      Includes Leo's modifications up to, and including, the
      platform_device to of_device adaptation:
      
      "The series of patches add generic QE infrastructure called
      qe_lib, and MPC8360EMDS board support.  Qe_lib is used by
      QE device drivers such as ucc_geth driver.
      
      This version updates QE interrupt controller to use new irq
      mapping mechanism, addresses all the comments received with
      last submission and includes some style fixes.
      
      v2: Change to use device tree for BCSR and MURAM;
      Remove I/O port interrupt handling code as it is not generic
      enough.
      
      v3: Address comments from Kumar;  Update definition of several
      device tree nodes;  Copyright style change."
      
      In addition, the following changes have been made:
      
      o removed typedefs
      o uint -> u32 conversions
      o removed following defines:
        QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
        BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
        because they hid sizeof/in_be32/out_be32 operations from the reader.
      o fixed qe_snums_init() serial num assignment to use a const array
      o made CONFIG_UCC_FAST select UCC_SLOW
      o reduced NR_QE_IC_INTS from 128 to 64
      o remove _IO_BASE, etc. defines (not used)
      o removed irrelevant comments, added others to resemble removed BD_ defines
      o realigned struct definitions in headers
      o various other style fixes including things like pinMask -> pin_mask
      o fixed a ton of whitespace issues
      o marked ioregs as __be32/__be16
      o removed platform_device code and redundant get_qe_base()
      o removed redundant comments
      o added cpu_relax() to qe_reset
      o uncasted all get_property() assignments
      o eliminated unneeded casts
      o eliminated immrbar_phys_to_virt (not used)
