As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWQC+cAAoJEIwa5zzehBx3jEUP/0GpxfDVanEUkudVLLe7J0RH CNlRan107Cw6hXRUJo7elEsuCALjccXjc1CAH4+RnNpOAeBKW97n+WU7trTv+wUZ sQX4SkBPKFBlgwGF2qhsi5q74gms/BrgtCa4kNb9joOYso039tlfIOPzK80DMkOm TkyIJdUCgFJMjCQLhX6kGT0PDcrbIjb6aA2cF3FAVeaJA7uz8lNe/eHJr3oHxIEY CvC651yJ2mIHQUU4BJx/AJo+wXg3dRUXNCAtBjwLRPEAzduYZXYm1ZTVIby/1q9r dR2KDFEuibODXmXrDBzKNJwCu/TLJEwo/1oPaEIVfY91XLKfiWUhgVqa1o1I+d9U XoGPibCW461qFahjQW87MfInALpCOA7/RbTNjFp+MVyipCYvkaYq7KFiYEldgFDx z4Qx/J4hYc2TlDWrpNiUCZMfmhwi7y+Ib+tnenYTO1eyMuw0e9mfnVdjk5iU3Pvk Ye4qPqpYclJruyHbYi164878+1lLaW2NCUgC3rkBO/GWPAzp7d9iLWoZ3PuyD5i5 PEjs668UcRdZYbI4rdrhGHL8Eq9Gnuc4Rthu7HxPOK+DG0XgP8r97PhM8aYGYVDO +yikBtjWRsA9fPj3rMKA3UsQ61DAeR9LmZ0XPGjWFMCjCG0JlUoIMaA+Uu0i8fr8 95qxBVxbO7rhL39r1rhV =dm+I -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere.

|
and uses a fixed setting for the output muxes.
|
|
Y1 is derived from the input clock
|
|
Y2 and Y3 derive from PLL1
|
