^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   21)  * Note that final HPT370 support was done by force extraction of GPL.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   22)  *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   23)  * - add function for getting/setting power status of drive
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   24)  * - the HPT370's state machine can get confused. reset it before each dma

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   27)  * - check for busmaster state at end of dma. 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   28)  * - use new highpoint timings.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   29)  * - detect bus speed using highpoint register.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   30)  * - use pll if we don't have a clock table. added a 66MHz table that's
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   31)  *   just 2x the 33MHz table.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   32)  * - removed turnaround. NOTE: we never want to switch between pll and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   33)  *   pci clocks as the chip can glitch in those cases. the highpoint
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   34)  *   approved workaround slows everything down too much to be useful. in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   35)  *   addition, we would have to serialize access to each chip.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   40)  * add /proc display for per-drive PIO/DMA/UDMA mode and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   41)  * per-channel ATA-33/66 Cable detect.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   48)  * Reset the hpt366 on error, reset on dma
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   49)  * Fix disabling Fast Interrupt hpt366.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   52)  * Added support for 372N clocking and clock switching. The 372N needs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   53)  * different clocks on read/write. This requires overloading rw_disk and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   54)  * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   55)  * keeping me sane.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   58)  * - fix the clock turnaround code: it was writing to the wrong ports when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   59)  *   called for the secondary channel, caching the current clock mode per-
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   60)  *   channel caused the cached register value to get out of sync with the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   61)  *   actual one, the channels weren't serialized, the turnaround shouldn't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   62)  *   be done on 66 MHz PCI bus
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   63)  * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   64)  *   does not allow for this speed anyway
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   65)  * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   66)  *   their primary channel is kind of virtual, it isn't tied to any pins)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   67)  * - fix/remove bad/unused timing tables and use one set of tables for the whole
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   68)  *   HPT37x chip family; save space by introducing the separate transfer mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   69)  *   table in which the mode lookup is done
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   70)  * - use f_CNT value saved by  the HighPoint BIOS as reading it directly gives
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   71)  *   the wrong PCI frequency since DPLL has already been calibrated by BIOS;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   72)  *   read it only from the function 0 of HPT374 chips
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   73)  * - fix the hotswap code:  it caused RESET- to glitch when tristating the bus,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   74)  *   and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   75)  * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   76)  *   they tamper with its fields
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   77)  * - pass  to the init_setup handlers a copy of the ide_pci_device_t structure
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   78)  *   since they may tamper with its fields
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   79)  * - prefix the driver startup messages with the real chip name
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   80)  * - claim the extra 240 bytes of I/O space for all chips
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   81)  * - optimize the UltraDMA filtering and the drive list lookup code
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   82)  * - use pci_get_slot() to get to the function 1 of HPT36x/374
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   83)  * - cache offset of the channel's misc. control registers (MCRs) being used
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   84)  *   throughout the driver
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   85)  * - only touch the relevant MCR when detecting the cable type on HPT374's
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   86)  *   function 1
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   87)  * - rename all the register related variables consistently
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   88)  * - move all the interrupt twiddling code from the speedproc handlers into
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   89)  *   init_hwif_hpt366(), also grouping all the DMA related code together there
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   90)  * - merge HPT36x/HPT37x speedproc handlers, fix PIO timing register mask and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   91)  *   separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   92)  *   when setting an UltraDMA mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   93)  * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   94)  *   the best possible one
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   95)  * - clean up DMA timeout handling for HPT370
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   96)  * - switch to using the enumeration type to differ between the numerous chip
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   97)  *   variants, matching PCI device/revision ID with the chip type early, at the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   98)  *   init_setup stage
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   99)  * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  100)  *   stop duplicating it for each channel by storing the pointer in the pci_dev
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  101)  *   structure: first, at the init_setup stage, point it to a static "template"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  102)  *   with only the chip type and its specific base DPLL frequency, the highest
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  103)  *   UltraDMA mode, and the chip settings table pointer filled,  then, at the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  104)  *   init_chipset stage, allocate per-chip instance  and fill it with the rest
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  105)  *   of the necessary information
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  106)  * - get rid of the constant thresholds in the HPT37x PCI clock detection code,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  107)  *   switch  to calculating  PCI clock frequency based on the chip's base DPLL
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  108)  *   frequency
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  109)  * - switch to using the  DPLL clock and enable UltraATA/133 mode by default on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  110)  *   anything  newer than HPT370/A (except HPT374 that is not capable of this
