2008-04-17[POWERPC] QE: immap_qe.h should include asm/io.hAnton Vorontsov
Headers should include prototypes they use, otherwise build will break if we use it without explicitly including io.h: CC arch/powerpc/sysdev/qe_lib/gtm.o In file included from include/asm/qe.h:20, from arch/powerpc/sysdev/qe_lib/gtm.c:18: include/asm/immap_qe.h: In function ‘immrbar_virt_to_phys’: include/asm/immap_qe.h:480: error: implicit declaration of function ‘virt_to_phys’ make[2]: *** [arch/powerpc/sysdev/qe_lib/gtm.o] Error 1 make[1]: *** [arch/powerpc/sysdev/qe_lib] Error 2 gtm.c needs qe.h (which includes immap_qe.h) to use qe_get_brg_clk().

2008-04-17[POWERPC] QE: implement qe_muram_offsetAnton Vorontsov
qe_muram_offset is the reverse of the qe_muram_addr, will be used for the Freescale QE USB Host Controller driver. This patch also moves qe_muram_addr into the qe.h header, plus adds __iomem hints to use with sparse.

2008-01-23[POWERPC] QE: Add ability to upload QE firmwareTimur Tabi
Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Added description of a new QE firmware node to booting-without-of.txt.

2007-10-08[POWERPC] qe: miscellaneous code improvements and fixes to the QE libraryTimur Tabi
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. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-10-04[POWERPC] QE: Added missing CEURNR registerEmil Medve
According to the publicly available MPC8360E RM (rev. 1 from 09/2006 and rev. 2 from 05/2007) and MPC8323E RM (rev. 1 from 09/2006), CEURNR is the QE microcode revision number register and is located at offset 0x1b8 within the QE internal register space Signed-off-by: Emil Medve <Emilian.Medve@Freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-03-29[POWERPC] qe: ucc_slow.guemr is in the wrong placeTimur Tabi
The definition of struct ucc_slow puts the guemr register immediately after the utpt register, when it should be at offset 0x90. This patch adds the missing 0x52-byte padding. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2006-11-13[PATCH] Optimize qe_brg struct to use an arrayTimur Tabi
The qe_brg structure manually defined each of the 16 BRG registers, which made any code that used them cumbersome. This patch replaces the fields with a single 16-element array.

2006-10-04[POWERPC] Add QUICC Engine (QE) infrastructureLi Yang
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) Signed-off-by: Li Yang <leoli@freescale.com> Signed-off-by: Shlomi Gridish <gridish@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
