Some changes that differ from upstream are only whitespace & re-ordering. This change syncs to the upstream version of changes. Signed-off-by: Alexandru Ardelean <[email protected]>
This change is mostly stylistic. No functionality change. The `code` variable is used for internal representation of the gain, while the `gain` refers to the actual gain value. Signed-off-by: Alexandru Ardelean <[email protected]>
This holds the gain min + max values for each chip. Signed-off-by: Alexandru Ardelean <[email protected]>
This change updates all strings referring to the supported amplifiers & attenuators that this driver supports. Signed-off-by: Alexandru Ardelean <[email protected]>

Last batch of changes that sync the driver with the upstream version.
The only thing that has not been upstreamed atm, is support for the HMC271 & HMC1119 attenuators.
The HMC271 chip is obsolete, so we may drop it from our tree (but we'll see).
The HMC1119 will probably be upstreamed later.
