[PATCH v2 0/8] qcom audio clock control drivers

[PATCH v2 0/8] qcom audio clock control drivers

[Stephen Boyd]

This patchset adds support for the low power audio subsystem (LPASS)
clock controller hardware. I split out the #define patch for IPQ so that
it can go through the clock tree and the arm-soc tree in parallel
if desired. New in this version is the msm8960/apq8064 support.

Change since v1:
 * Renamed clk-cdiv to clk-regmap-divider
 * Added msm8960/apq8064 support
 * Split out dividers and branches to check for halt bits

Josh Cartwright (1):
  clk: qcom: Add support for regmap divider clocks

Rajendra Nayak (3):
  dt-bindings: Add #defines for IPQ806x lpass clock control
  clk: qcom: Add IPQ806X LPASS clock controller (LCC) driver
  devicetree: bindings: Document qcom,lcc

Stephen Boyd (4):
  clk: Add __clk_mux_determine_rate_closest
  clk: divider: Make generic for usage elsewhere
  clk: qcom: Add simple regmap based muxes
  clk: qcom: Add MSM8960/APQ8064 LPASS clock controller (LCC) driver

+Qualcomm LPASS Clock & Reset Controller Binding
+------------------------------------------------
+
+Required properties :
+- compatible : shall contain only one of the following:
+
+			"qcom,lcc-msm8960"
+			"qcom,lcc-apq8064"
+			"qcom,lcc-ipq8064"
+
+- reg : shall contain base register location and length
+- #clock-cells : shall contain 1
+- #reset-cells : shall contain 1
+
+Example:
+	clock-controller@28000000 {
+		compatible = "qcom,lcc-ipq8064";
+		reg = <0x28000000 0x1000>;
+		#clock-cells = <1>;
