Hi,

I've been going through PATA drivers for the last few days to make
sure that we offer similar level of hardware support in the new PATA
drivers as with the old IDE subsystem and the following patchset is
the end result of said audit.


Inside:

- many bugfixes

   ( ata_piix, pata_artop, pata_atiixp, pata_efar, pata_cmd64x,
     pata_hpt3x3, pata_it8213, pata_legacy, pata_ns87415, pata_sis,
     pata_radisys, pata_rz1000&  pata_via )

- add Power Management support for more controllers

   ( pata_artop, pata_pdc2027x, pata_sl82c105 )

- add 32-bit PIO support for more controllers

   ( pata_artop, pata_atiixp, pata_efar, pata_cmd64x, pata_cs5520,
     pata_cs5530, pata_cs5535, pata_cypress, pata_hpt366, pata_hpt37x,
     pata_hpt3x2n, pata_it8213, pata_it821x, pata_jmicron, pata_ns87415,
     pata_opti, pata_pdc2027x, pata_pdc202xx_old, pata_rz1000,
     pata_sc1200, pata_scc, pata_sch, pata_serverworks, pata_sl82c105,
     pata_sis, pata_triflex&  pata_via )

- fix QDI65x0 support in pata_legacy driver so pata_qdi driver can
   be finally removed

- remove pata_qdi and pata_winbond drivers resulting in 600 LOC gone

   (affected hardware is fully supported by pata_legacy driver now)

- unify code for programming PIO and MWDMA timings for 'PIIX-like'
   controllers resulting in 200 LOC gone

   ( ata_piix, pata_efar, pata_it8213, pata_oldpiix, pata_radisys&
     pata_rdc )

- add ->init_host method for abstracting host specific controller
   initialization and then use it to cleanup Power Managment code
   resulting in over 100 LOC gone

   ( pata_ali, pata_amd, pata_artop, pata_cmd640, pata_cmd64x,
     pata_cs5530, pata_hpt366, pata_hpt3x3, pata_it821x, pata_ninja32,
     pata_ns87415, pata_pdc2027x&  sata_sil )

- misc fixes and cleanups

What are your plans for 2.6.33?

The merge window is upon us, which by strict rules means that anything 
not already in libata-dev.git#upstream needs to wait until 2.6.34.

However, bug fixes and the like should definitely be in 2.6.33. 
->init_host is definitely 2.6.34 material.  Some of the other stuff 
could go either way.
