[media] ivtv: Add Adaptec Remote Controller
lirc-i2c implements a get key logic for the Adaptec Remote
Controller, at address 0x6b. The only driver that seems to have
an Adaptec device is ivtv:
$ git grep -i adaptec drivers/media
drivers/media/video/cs53l32a.c: * cs53l32a (Adaptec AVC-2010 and AVC-2410) i2c ivtv driver.
drivers/media/video/cs53l32a.c: * Audio source switching for Adaptec AVC-2410 added by Trev Jackson
drivers/media/video/cs53l32a.c: /* Set cs53l32a internal register for Adaptec 2010/2410 setup */
drivers/media/video/ivtv/ivtv-cards.c:/* Adaptec VideOh! AVC-2410 card */
drivers/media/video/ivtv/ivtv-cards.c: { PCI_DEVICE_ID_IVTV16, IVTV_PCI_ID_ADAPTEC, 0x0093 },
drivers/media/video/ivtv/ivtv-cards.c: .name = "Adaptec VideOh! AVC-2410",
drivers/media/video/ivtv/ivtv-cards.c:/* Adaptec VideOh! AVC-2010 card */
drivers/media/video/ivtv/ivtv-cards.c: { PCI_DEVICE_ID_IVTV16, IVTV_PCI_ID_ADAPTEC, 0x0092 },
drivers/media/video/ivtv/ivtv-cards.c: .name = "Adaptec VideOh! AVC-2010",
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_CARD_AVC2410 7 /* Adaptec AVC-2410 */
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_CARD_AVC2010 8 /* Adaptec AVD-2010 (No Tuner) */
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_PCI_ID_ADAPTEC 0x9005
drivers/media/video/ivtv/ivtv-driver.c: "\t\t\t 8 = Adaptec AVC-2410\n"
drivers/media/video/ivtv/ivtv-driver.c: "\t\t\t 9 = Adaptec AVC-2010\n"
drivers/media/video/ivtv/ivtv-i2c.c: 0x6b, /* Adaptec IR */
There are two Adaptec cards defined there, but AVC-2010 doesn't have a
remote controller. So, the logic at lirc_i2c seems to be for Adaptec AVC-2410.
As we'll remove lirc_i2c from kernel, move the getkey code to ivtv driver, and
use it for AVC-2410.
