[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.
