From 3aa2b3b9cc7cf58d044f30dcad849bff037abd25 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 5 Mar 2013 06:55:27 -0300 Subject: [PATCH] [media] em28xx: Add a separate config dir for secondary bus Prepare to register a separate bus for the second bus. For now, just add a new field. A latter patch will add the bits to make it work. This patch was generated by this script: perl -e 'while (<>) { if (s/EM2874_I2C_SECONDARY_BUS_SELECT.*\n//) { printf "\t\t.def_i2c_bus = 1,\n"; $found = 1; print $_ } else { if ($found) { s/^\s+// }; $found = 0; print $_; } }' \ drivers/media/usb/em28xx/em28xx-cards.c >a && mv a drivers/media/usb/em28xx/em28xx-cards.c Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/em28xx/em28xx-cards.c | 43 +++++++++++++------------ drivers/media/usb/em28xx/em28xx.h | 1 + 2 files changed, 24 insertions(+), 20 deletions(-) diff --git a/drivers/media/usb/em28xx/em28xx-cards.c b/drivers/media/usb/em28xx/em28xx-cards.c index d81f7ee94c41..16ab4d7780b3 100644 --- a/drivers/media/usb/em28xx/em28xx-cards.c +++ b/drivers/media/usb/em28xx/em28xx-cards.c @@ -958,8 +958,8 @@ struct em28xx_board em28xx_boards[] = { #else .tuner_type = TUNER_ABSENT, #endif - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, [EM2884_BOARD_HAUPPAUGE_WINTV_HVR_930C] = { @@ -974,8 +974,8 @@ struct em28xx_board em28xx_boards[] = { .tuner_type = TUNER_ABSENT, #endif .ir_codes = RC_MAP_HAUPPAUGE, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, [EM2884_BOARD_CINERGY_HTC_STICK] = { @@ -983,8 +983,8 @@ struct em28xx_board em28xx_boards[] = { .has_dvb = 1, .ir_codes = RC_MAP_NEC_TERRATEC_CINERGY_XS, .tuner_type = TUNER_ABSENT, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, [EM2880_BOARD_HAUPPAUGE_WINTV_HVR_900] = { @@ -1404,8 +1404,8 @@ struct em28xx_board em28xx_boards[] = { }, [EM2874_BOARD_LEADERSHIP_ISDBT] = { - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_100_KHZ, .xclk = EM28XX_XCLK_FREQUENCY_10MHZ, .name = "EM2874 Leadership ISDBT", @@ -1917,8 +1917,8 @@ struct em28xx_board em28xx_boards[] = { * Empia EM28174, Sony CXD2820R and NXP TDA18271HD/C2 */ [EM28174_BOARD_PCTV_290E] = { .name = "PCTV nanoStick T2 290e", - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_100_KHZ, + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_100_KHZ, .tuner_type = TUNER_ABSENT, .tuner_gpio = pctv_290e, .has_dvb = 1, @@ -1927,8 +1927,8 @@ struct em28xx_board em28xx_boards[] = { /* 2013:024f PCTV DVB-S2 Stick 460e * Empia EM28174, NXP TDA10071, Conexant CX24118A and Allegro A8293 */ [EM28174_BOARD_PCTV_460E] = { - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, .name = "PCTV DVB-S2 Stick (460e)", .tuner_type = TUNER_ABSENT, .tuner_gpio = pctv_460e, @@ -1958,8 +1958,8 @@ struct em28xx_board em28xx_boards[] = { .tuner_type = TUNER_ABSENT, .tuner_gpio = maxmedia_ub425_tc, .has_dvb = 1, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, /* 2304:0242 PCTV QuatroStick (510e) @@ -1970,8 +1970,8 @@ struct em28xx_board em28xx_boards[] = { .tuner_gpio = pctv_510e, .has_dvb = 1, .ir_codes = RC_MAP_PINNACLE_PCTV_HD, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, /* 2013:0251 PCTV QuatroStick nano (520e) @@ -1982,8 +1982,8 @@ struct em28xx_board em28xx_boards[] = { .tuner_gpio = pctv_520e, .has_dvb = 1, .ir_codes = RC_MAP_PINNACLE_PCTV_HD, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, [EM2884_BOARD_TERRATEC_HTC_USB_XS] = { @@ -1991,8 +1991,8 @@ struct em28xx_board em28xx_boards[] = { .has_dvb = 1, .ir_codes = RC_MAP_NEC_TERRATEC_CINERGY_XS, .tuner_type = TUNER_ABSENT, - .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT | - EM28XX_I2C_CLK_WAIT_ENABLE | + .def_i2c_bus = 1, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | EM28XX_I2C_FREQ_400_KHZ, }, };
