When the configuration is changed, they are also written to the adapter. This allows the adapter to continue operating in autonomous mode with the same settings when it is disconnected from the driver (typically by going into suspend). For adapters with firmware version 2 or greater, the settings are also persisted in EEPROM. A new module parameter is added to optionally also use the configuration already present in the adapter when it is connected. This option is enabled by default. When a new configuration is written, the autonomous mode is automatically enabled. When the device is unconfigured, autonomous mode is disabled. Signed-off-by:

It makes sense for adapters such as the Pulse-Eight to be configurable both from within the driver and from user space, so remove the requirement that drivers only can call cec_s_log_addrs or cec_s_phys_addr if they don't expose those capabilities to user space. Signed-off-by:

The driver should not ignore errors while registering the I2C bus, as this device can't even minimally work without the buses, as it uses those buses internally to talk with the several IP blocks inside the chip. Cc: stable@vger.kernel.org Signed-off-by: -

The cx231xx_get_i2c_adap() function should return the I2C adapter that will be used to talk with a device. It should never be NULL, as otherwise the driver will try to dereference a null pointer. We might instead fix the callers, but if this condition ever happens, it is really a driver bug, because i2c_port should always be a value from enum CX231XX_I2C_MASTER_PORT. Found when checking the code due to this bug: [ 39.769021] BUG: unable to handle kernel NULL pointer dereference at 0000000000000002 [ 39.769105] IP: [<ffffffff81638393>] i2c_master_send+0x13/0x70 Signed-off-by: -

With the current settings, only one channel locks properly. That's likely because, when this driver was written, Brazil were still using experimental transmissions. Change it to reproduce the settings used by the newer drivers. That makes it lock on other channels.

On this frontend, it takes a while to start output normal TS data. That only happens on state S9. On S8, the TS output is enabled, but it is not reliable enough. However, the zigzag loop is too fast to let it sync. As, on practical tests, the zigzag software loop doesn't seem to be helping, but just slowing down the tuning, let's switch to hardware algorithm, as the tuners used on such devices are capable of work with frequency drifts without any help from software.
