From 6394cf53abc0b3a2db9e8b947ef5c77b16861ec8 Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Sat, 29 Mar 2008 20:49:57 -0300 Subject: [PATCH] V4L/DVB (7469): Preparation for supporting new devices, cleanup and saneness To prepare the support for new device to the flexcop-family some preparation and cleanups was done + some saneness: - created an i2c-adapter for each i2c-port available. Easier usage for devices with several device on different i2c-busses - initialize i2c before doing the eeprom read - changed the way to attach the different frontends, easier to read now - enabled support for i2c-devices having no register address (1-byte access) Signed-off-by: Patrick Boettcher Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb/b2c2/flexcop-common.h | 17 +- drivers/media/dvb/b2c2/flexcop-eeprom.c | 9 +- drivers/media/dvb/b2c2/flexcop-fe-tuner.c | 111 +++++++------ drivers/media/dvb/b2c2/flexcop-i2c.c | 180 +++++++++++++++------- drivers/media/dvb/b2c2/flexcop-usb.c | 17 +- drivers/media/dvb/b2c2/flexcop.c | 10 +- 6 files changed, 221 insertions(+), 123 deletions(-) diff --git a/drivers/media/dvb/b2c2/flexcop-common.h b/drivers/media/dvb/b2c2/flexcop-common.h index 5a6c4fe249..8ce06336e7 100644 --- a/drivers/media/dvb/b2c2/flexcop-common.h +++ b/drivers/media/dvb/b2c2/flexcop-common.h @@ -44,6 +44,14 @@ struct flexcop_dma { u32 size; /* size of each address in bytes */ }; +struct flexcop_i2c_adapter { + struct flexcop_device *fc; + struct i2c_adapter i2c_adap; + + u8 no_base_addr; + flexcop_i2c_port_t port; +}; + /* Control structure for data definitions that are common to * the B2C2-based PCI and USB devices. */ @@ -72,7 +80,7 @@ struct flexcop_device { struct dmx_frontend mem_frontend; int (*fe_sleep) (struct dvb_frontend *); - struct i2c_adapter i2c_adap; + struct flexcop_i2c_adapter fc_i2c_adap[3]; struct mutex i2c_mutex; struct module *owner; @@ -87,7 +95,8 @@ struct flexcop_device { int (*write_ibi_reg) (struct flexcop_device *, flexcop_ibi_register, flexcop_ibi_value); - int (*i2c_request) (struct flexcop_device*, flexcop_access_op_t, flexcop_i2c_port_t, u8 chipaddr, u8 addr, u8 *buf, u16 len); + int (*i2c_request) (struct flexcop_i2c_adapter*, + flexcop_access_op_t, u8 chipaddr, u8 addr, u8 *buf, u16 len); int (*stream_control) (struct flexcop_device*, int); int (*get_mac_addr) (struct flexcop_device *fc, int extended); @@ -128,8 +137,8 @@ int flexcop_eeprom_check_mac_addr(struct flexcop_device *fc, int extended); * one.
