[PATCH 0/2] clk: qcom: add MSM8x60 LPASS Clock Controller

[Herman van Hazendonk <github.com@herrie.org>]

Hi all,

This series adds the LPASS (Low Power Audio SubSystem) Clock Controller
driver for the MSM8x60 family of SoCs (MSM8260/MSM8660/APQ8060) - the
Scorpion-class generation that preceded MSM8960's Krait CPUs.

The register layout, parent muxing and divider topology of the LPASS
PLL/clk fabric differ from MSM8960's LCC enough that a clean separate
driver is simpler than parameterising lcc-msm8960.c. Both drivers can
coexist (different Kconfig, match table and compatible).

Used on the HP TouchPad (Tenderloin) where the LPASS Q6 audio DSP needs
functional MI2S / SLIMBus / PCM clocks before audio playback or capture
works.

The new binding header is dual-licensed (GPL-2.0-only OR BSD-2-Clause)
per current qcom-binding convention.

Companion to the MSM8x60 MMCC series.

Thanks,
Herman
