Now that the mfd is using the register map cache there's no need for the CODEC driver to do any register cache management or any funny dances to interact with the other drivers using the device so just remove the cache initialisation and volatility information.

For later chip revisions the WM1811 GPIO6 register is always volatile so store the device revision when initialising the driver and then check at runtime if we're running on a newer device.

struct wm8994 includes a mutex so we need to include mutex.h before we declare it. All current users rely on this being done implicitly. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>

As WM1811 revision C was transparent to software the revision IDs for subsequent revisions are one less than they would normally be. Correct for this in log messages. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>

Mark Brown authored
The different devices handled by the WM8994 can be distinguished using their ID registers so we don't need to rely on the user having registered the device correctly. Instead do the initial regmap setup with a minimal configuration only supporting physical I/O and then configure the cache once we have identified the device.

As part of this we provide information about the registers that exist in the device to the regmap core, drop the small amount of cache that the core had been using and let regmap do the sync.

Describe the register map to the regmap core so that we can use its diagnostic features and cache support. This is split out from the patch using it due to the size so that the actual code change is a bit clearer. As the various devices are supersets of each other the access maps are built up by layering the functions on top of each other, though the interface for specifying the register defaults isn't currently amenable to this.

Disable more pulls by default on WM8994 for a small current saving. Since some designs do leave SPKMODE floating provide platform data to allow that to be left enabled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>

Add a placeholder device tree binding for the wm8994 driver. At present the binding is essentially null as none of the platform data is supported, and at least some of that will depend on the pending regulator bindings.

Transform some loops from: for_each(x) { if (f(x)) { work_on(x); } } to new structure: for_each(x) { if (!f(x)) continue; work_on(x); } This will allow future modification of f(x) with less impact to the code.

Move DAS routing setup into the DAS driver itself. This removes the need to duplicate this in each machine driver, of which we'll soon have three. An added advantage is that the machine drivers no longer call the Tegra20- specific DAS functions by name, so the machine driver no longer needs to be split up into Tegra20 and Tegra30 versions. If individual machine drivers need a different routing setup to this default, they can still call the DAS functions to set that up. Long-term, DAS will be a codec driver, and user-space will be able to control its routing, possibly within constraints that the machine driver sets up. Configuring the DAS routing from the DAS driver is a very slight move in that direction.
