[ Upstream commit d4f9b5428b53dd67f49ee8deed8d4366ed6b1933 ] WM8994 chip has built-in regulators, which might be used for chip operation. They are controlled by a separate wm8994-regulator driver, which should be loaded before this driver calls regulator_get(), because that driver also provides consumer-supply mapping for the them. If that driver is not yet loaded, regulator core substitute them with dummy regulator, what breaks chip operation, because the built-in regulators are never enabled. Fix this by annotating this driver with MODULE_SOFTDEP() "pre" dependency to "wm8994_regulator" module.

commit a8ff78f7f773142eb8a8befe5a95dd6858ebd635 upstream. Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci in MTRR. This will cause the system to hang during boot.

The si476x_core_get_revision_info will send i2c command to FM module, if it return error, there is no FM modules attached, so we need't to register the sound card. otherwise, the pulseaudio will access this sound card, but return a lot of i2c error.

2019-11-25MLK-10038-1: mfd: si476x-i2c: Add support of si476x-rev4.0 boardZidan Wang
Currently, si476x-rev1.0 and si476x-rev4.0 board just support A10 compatible command set. For si476x-rev1.0 board, its firmware revision is unsupported and will revert to A10 compatible function. For si476x-rev4.0 board, its firmware revision is two and will use A30 function, but A30 command set function can't work for the rev4.0 board. So make the command set configurable in dts. If "revision-a10" is present, set the revision to SI476X_REVISION_A10 to use A10 compatible commit set. Otherwise, get the revision from si476x register.

2019-11-25mfd: max17135: fix kernel warning at boot time when max17135 is not detectededRobby Cai
in 5451781dadf85000665e0e2c3288e9e0f34b860a commit, it added the check that the regulator need to be disabled before calling regulator_put(). If not do so, the kernel will print warning message as below. To fix this, need to disable regulator before probe function return if this PMIC is not found. regulator_put() will be called when probe fails in this case as devm_regulator_get() already called in probe function.

2019-09-24thermal: db8500: Finalize device tree conversionLinus Walleij
At some point there was an attempt to convert the DB8500 thermal sensor to device tree: a probe path was added and the device tree was augmented for the Snowball board. The switchover was never completed: instead the thermal devices came from from the PRCMU MFD device and the probe on the Snowball was confused as another set of configuration appeared from the device tree. Move over to a device-tree only approach, as we fixed up the device trees.
