These cards are displayed by lspci -nn as "Softlogic Co., Ltd. SOLO6110 H.264 Video encoder/decoder [9413:6110]" Bluecherry cards have 4 x TW2864A. According to datasheet register 0xFF of TW2864B chips contains value 0x6A or 0x6B depending on revision which being shifted 3 bits right gives value 0x0d. Existing version of solo6x10 fails on these cards with [276582.344942] solo6x10 0000:07:00.0: Probing Softlogic 6110 [276582.402151] solo6x10 0000:07:00.0: Could not initialize any techwell chips [276582.402781] solo6x10: probe of 0000:07:00.0 failed with error -22 Signed-off-by: Anton Sviridenko Acked-by: Andrey Utkin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/pci/solo6x10/solo6x10-tw28.c b/drivers/media/pci/solo6x10/solo6x10-tw28.c index 1c013a03d851..7ecb725b6dd2 100644 --- a/drivers/media/pci/solo6x10/solo6x10-tw28.c +++ b/drivers/media/pci/solo6x10/solo6x10-tw28.c @@ -606,6 +606,7 @@ int solo_tw28_init(struct solo_dev *solo_dev) solo_dev->tw28_cnt++; break; case 0x0c: + case 0x0d: solo_dev->tw2864 |= 1 << i; solo_dev->tw28_cnt++; break;
