From 1be90df9422b4ee4d6343477eda998c5d3e3e488 Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Sat, 29 Mar 2008 21:49:57 +0100 Subject: Preparation for supporting new devices, cleanup and saneness From: Patrick Boettcher 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 --- linux/drivers/media/dvb/b2c2/flexcop-common.h | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'linux/drivers/media/dvb/b2c2/flexcop-common.h') diff --git a/linux/drivers/media/dvb/b2c2/flexcop-common.h b/linux/drivers/media/dvb/b2c2/flexcop-common.h index 49852ba16..22fc0490d 100644 --- a/linux/drivers/media/dvb/b2c2/flexcop-common.h +++ b/linux/drivers/media/dvb/b2c2/flexcop-common.h @@ -47,6 +47,14 @@ 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. */ @@ -75,7 +83,7 @@ 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]; #if LINUX_VERSION_CODE > KERNEL_VERSION(2,6,15) struct mutex i2c_mutex; #else @@ -94,7 +102,8 @@ 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); @@ -135,8 +144,8 @@ int flexcop_eeprom_check_mac_addr(struct flexcop_device *fc, int extended); * one.
