| Subject: [PATCH] pata_pdc202xx_old: fix UDMA mode for PDC2026x chipsets |
| |
| commit 750e519da7b3f470fe1b5b55c8d8f52d6d6371e4 upstream. |
| |
| PDC2026x chipsets need the same treatment as PDC20246 one. |
| |
| This is completely untested but will hopefully fix UDMA issues |
| that people have been reporting against pata_pdc202xx_old for |
| the last couple of years. |
