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.

This patch adds driver for mxl301rf OFDM tuner chips. It is used as an ISDB-T tuner in earthsoft pt3 cards. Note that this driver does not initilize the chip, because the initilization sequence / register setting is not disclosed. Thus, the driver assumes that the chips are initilized externally by its parent board driver before tuner_ops->init() are called, like in PT3 driver where the bridge chip contains the init sequence in its private memory and provides a command to trigger the sequence.

2014-09-23[media] media: tuner xc5000 - try to avoid firmware load in resume pathShuah Khan
xc5000 doesn't load firmware at attach time instead loads it when it needs to set and change configuration from its init, frequency, digital and analog mode set interffaces. As a result, when system is suspended before firmware is loaded, firmware load can be avoided during resume. Loading formware in this scenario results in slowpath warnings during resume as it won't be in the suspend firmware cache.

2014-09-23[media] si2157: Add support for Si2147-A30 tunerOlli Salonen
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.

Old IT9135 AX needs a little bit different register settings for sleep than newer IT9135 BX. This has been broken always, as power management of the whole driver, but it started to be problem as I fixed clock. Earlier clock was disabled very first on sleep and rest of the commands were skipped by the chip as no clock, leaving tuner full power state. When I fixed clocks these PM bugs started raising out as I/O errors.

2014-09-21[media] it913x: fix tuner sleep power leakAntti Palosaari
IT913x tuner driver disables own clock, provided by demod core, as very a first operation when tuner is put on *sleep*. That likely causes failure of all the rest commands on sleep sequence, which leads situation where tuner is not actually on sleep, but consuming a lot of power. I measured 102mA current consumption from the USB before change and after change it was only 32mA. Used device was single tuner IT9135 BX. Second reason to remove that register from tuner driver is reason it is simply on wrong driver (demod vs. tuner), breaking the principle of correct driver. Clock is now provided more correctly af9033 demod driver as a config option.
