[PATCH v3 0/8] qcom audio clock control drivers

[PATCH v3 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.

Changes since v2:
 * Rebased onto v3.19-rc2
 * One fix to a clock parent name

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

Verified all supported bit clock frequencies for audio playback work on
the ipq806x SOC with max98357a codec.

Applied to clk-next.
