* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings + incorrect base clock being set for controller in the passthrough mode * move code limiting max PIO according to the pair device capabilities from config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also applied for mode change requests coming through ->tuneproc and ->speedproc interfaces * set device speed in it821x_tuneproc() * in it821x_tune_chipset() call it821x_tuneproc() also if the controller is in the smart mode (so the check for pair device max PIO is done) * rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc() wrapper which does the max PIO mode check; it worked by the pure luck previously, pio[4] and pio_want[4] arrays were used with index == 255 so random PIO timings and base clock were set for the controller in the passthrough mode, thankfully PIO timings and base clock were corrected later by config_it821x_chipset_for_pio() call (but it was not called for PIO-only devices during resume and for user requested PIO autotuning) * remove config_it821x_chipset_for_pio() call from config_chipset_for_dma() as the driver sets ->autotune to 1 and ->tuneproc does the proper job now * convert the last user of config_it821x_chipset_for_pio() to use it821x_tuneproc(drive, 255) and remove no longer needed function While at it: * fix few comments * bump driver version Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> |
