2021-12-14media: si2157: add ATV support for si2158Mauro Carvalho Chehab1-0/+3
This device also supports ATV, as it has the same API for setting analog TV tuning parameters. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-12-14media: si2157: add support for 1.7MHz and 6.1 MHzMauro Carvalho Chehab1-0/+5
Some tuners allow setting the bandwidth filter to 1.7MHz and 6.1 MHz. Add support for it upstream, as the narrower is the bandwidth filter, the better. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-12-14media: si2157: get rid of chiptype dataMauro Carvalho Chehab1-6/+1
The driver should be capable of autodetecting its type, so no need to pass it via device driver's data. While here, improve documentation of some of the part_id specific code. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-12-14media: si2157: use a different namespace for firmwareMauro Carvalho Chehab1-0/+31
Each chip at the si21xx TER family seems to have a different firmware, with seems to actually be a patch against the ROM code. Rework the code in order to use different firmware files depending on the chip ID and rom ID. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-21media: si2157: Add analog tuning related functionsBrad Love1-0/+2
Include set_analog_params, get_frequency, and get_bandwidth. Tested with NTSC and PAL standards via ch3/4 generator. Other standards are included, but are untested due to lack of generator.

2017-04-14[media] si2157: Add support for Si2141-A10Stefan Brüns1-0/+2
The Si2141 needs two distinct commands for powerup/reset, otherwise it will not respond to chip revision requests. It also needs a firmware to run properly.

2017-04-14[media] si2157: revert si2157: Si2141/2151 tuner supportAntti Palosaari1-2/+0
'Reset' loop does not look correct. I tested it very many times and it never repeated those commands. If problem, it tries to solve, really occurs on some situations better solution should be find out. There is another patch which does not have such hackish looking loop. Lets change to it.

2016-05-06[media] si2157: detect if firmware is runningAntti Palosaari1-1/+0
Detect if firmware is running run-time and download / start it only when needed. Detection is done by reading IF frequency value. Garbage value is returned by firmware when it is not running, otherwise correct value is returned.

2015-05-12[media] si2157: support selection of IF interfaceOlli Salonen1-0/+1
The chips supported by the si2157 driver have two IF outputs (either pins 12+13 or pins 9+11). Instead of hardcoding the output to be used add an option to choose which output shall be used. As this patch changes the default behaviour, the IF interface is specified in each driver currently using si2157 driver. This is to keep bisectability.

2015-01-29[media] si2157: carry pointer to client instead of state in tuner_privAntti Palosaari1-1/+0
Carry struct i2c_client pointer in tuner_priv. This driver is I2C driver, which is represented as a struct i2c_client, so better to carry this top level structure for each routine in order to unify things.

2014-11-25[media] si2157: Add support for Si2146-A10Olli Salonen1-2/+6
The Silicon Labs Si2146 tuner seems to work with the same driver as the Si2157, but there a few exceptions. The powerup command seems to be quite a bit different. In addition there's a property 0207 that requires a different value. Thus another entry is created in the si2157_id table to support also si2146 in this driver.

2014-09-23[media] si2157: Add support for Si2147-A30 tunerOlli Salonen1-1/+1
This patch adds support for Si2147-A30 tuner. Fairly trivial, no firmware needed for this tuner. However, command 14 00 02 07 01 00 seems to be mandatory. On Si2157 and Si2158 the value 0x0100 is the default value, so this patch does not impact the existing tuners/devices. On Si2147 the default is 0x0000 and I can't get a lock with that value. While here, fix the return length of the previous set command to 4 bytes.
