PATCH v2 1/12 cx231xx: don't return error on success
From: Mauro Carvalho Chehab <[email protected]>
The cx231xx_set_agc_analog_digital_mux_select() callers expect it to return 0 or an error. That makes the first attempt to switch between analog/digital to fail.

PATCH v2 2/12 cx231xx: fix GPIOs for Pixelview SBTVD hybrid
In reply to Mauro Carvalho ChehabFrom: Mauro Carvalho Chehab <[email protected]>
This device uses GPIOs: 28 to switch between analog and digital modes: on digital mode, it should be set to 1.
The code that sets it on analog mode is OK, but it misses the logic that sets it on digital mode.

PATCH v2 4/12 mb86a20s: fix the locking logic
In reply to Mauro Carvalho ChehabFrom: Mauro Carvalho Chehab <[email protected]>
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.

PATCH v2 6/12 mb86a20s: fix demod settings
In reply to Mauro Carvalho ChehabFrom: Mauro Carvalho Chehab <[email protected]>
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.

PATCH v2 8/12 cx231xx-i2c: handle errors with cx231xx_get_i2c_adap()
In reply to Mauro Carvalho ChehabThe 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:
