This patchset is a first round of update to the meson clock controllers to bring audio support. The patchset is based on clk-next. It could be rebased on amlogic tree later on, if you prefer the patches to go through Kevin's tree.I'd prefer these go through the clk tree, and get an immutable branch that I can use for my stuff that goes through the arm-soc tree.
Applied to clk-meson, a stable branch, which has been merged into clk-next. Kevin, feel free to use clk-meson or any commit id therein: they will not be rebased. Regards, Mike

First patch fix an issue found while writing patch 5 (Giving ternary operator to SET_PARM) Following Stephen comment on the v1, patch 2 adds the const qualifiers missing upstream. Patches 3 and 4 put the generic muxes and divisors declaration in tables so the register address fixup works in the same way as the clock gates. We are going to add more of these clock types for audio or gpu support, so we can't continue to fix addresses individually like it is currently done. Patches 5 to 8 improve the support of the mpll clocks, now allowing the rate to be set. Among other things, the mplls are the parent clocks of the i2s and spdif clocks. Patch 9 expose the clock gates required to power on the i2s output. These patches have been tested on the meson gxbb p200 board, as part of the ongoing work to bring audio support to meson SoC family. Changes since v1 [0]: * Add SET_PARM fix to the series * Add missing const qualifiers to the clock arrays * No more additional patches required as SAR clocks have been merged [0]: http://lkml.kernel.org/r/20170228133002.17894-1-jbrunet@baylibre.com Jerome Brunet (9): clk: meson: fix SET_PARM macro clk: meson: add missing const qualifiers on gate arrays clk: meson8b: put dividers and muxes in tables clk: gxbb: put dividers and muxes in tables clk: meson: mpll: add rw operation clk: meson: gxbb: mpll: use rw operation clk: meson8b: add the mplls clocks 0, 1 and 2 clk: meson: mpll: correct N2 maximum value dt-bindings: clk: gxbb: expose i2s output clock gates drivers/clk/meson/clk-mpll.c | 152 ++++++++++++++++++++++++++++++++-- drivers/clk/meson/clkc.h | 6 +- drivers/clk/meson/gxbb.c | 66 ++++++++++++--- drivers/clk/meson/gxbb.h | 10 +-- drivers/clk/meson/meson8b.c | 127 ++++++++++++++++++++++++++-- drivers/clk/meson/meson8b.h | 20 ++++- include/dt-bindings/clock/gxbb-clkc.h | 5 ++ 7 files changed, 356 insertions(+), 30 deletions(-)
