2017-08-23clk: qcom: msm8916: Fix bimc gpu clock opsGeorgi Djakov
The clock bimc_gpu_clk_src is incorrectly set to use the shared rcg2 ops, which are for RCGs with child branches controlled by different CPUs. The result of the incorrect ops is that the GPU's PM runtime may leave this clock set at a very low rate. Fix this issue by using the correct rcg2 ops.

2017-06-19clk: gcc-msm8916: add support to 9.6MHz codec clkSrinivas Kandagatla
MCLK for internal audio codec is expected to be at 9.6MHz by default. This patch adds support to 9.6MHz to make the default case possible. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2016-11-23clk: qcom: Move all sdcc rcgs to use clk_rcg2_floor_opsRajendra Nayak
The sdcc driver for msm8996/msm8916/msm8974/msm8994 and apq8084 expects a clk_set_rate() on the sdcc rcg clk to set a floor value of supported clk rate closest to the requested rate, by looking up the frequency table. So move all the sdcc rcgs on all these platforms to use the newly introduced clk_rcg2_floor_ops Signed-off-by: Rajendra Nayak <rnayak@codeaurora.org> Signed-off-by: Ritesh Harjani <riteshh@codeaurora.org> Signed-off-by: Jeremy McNicoll <jeremymc@redhat.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

* clk-fixes: clk: gpio: Really allow an optional clock= DT property Revert "clk: qcom: Specify LE device endianness"
2016-02-12Revert "clk: qcom: Specify LE device endianness"Stephen Boyd
This reverts commit 329cabcecf94d8d7821e729dda284ba9dec44c87. The commit that caused us to specify LE device endianness here, 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write, 2015-10-29), has been reverted in mainline so now when we specify LE it actively breaks big endian kernels because the byte swapping in regmap-mmio is incorrect. Let's revert this change because it will 1) fix the big endian kernels and 2) be redundant to specify LE because that will become the default soon.

2015-11-20clk: qcom: msm8916: Move xo and sleep clocks into DTGeorgi Djakov
Move the xo and sleep clocks to device-tree, instead of hard-coding them in the driver. This allows us to insert the RPM clocks (if they are enabled) in between the on-board oscillators and the actual clock.

2015-11-20clk: qcom: Specify LE device endiannessStephen Boyd
All these clock controllers are little endian devices, but so far we've been relying on the regmap mmio bus handling this for us without explicitly stating that fact. After commit 4a98da2164cf (regmap-mmio: Use native endianness for read/write, 2015-10-29), the regmap mmio bus will read/write with the __raw_*() IO accessors, instead of using the readl/writel() APIs that do proper byte swapping for little endian devices. So if we're running on a big endian processor and haven't specified the endianness explicitly in the regmap config or in DT, we're going to switch from doing little endian byte swapping to big endian accesses without byte swapping, leading to some confusing results. On my apq8074 dragonboard, this causes the device to fail to boot as we access the clock controller with big endian IO accesses even though the device is little endian. Specify the endianness explicitly so that the regmap core properly byte swaps the accesses for us.

2015-09-16clk: qcom: Allow clk_set_parent() to work on display clocksStephen Boyd
Sometimes the display driver may want to change the parent PLL of the display clocks (byte and pixel clocks) depending on the use-case. Currently the parent is fixed by means of having a frequency table with one entry that chooses a particular parent. Remove this restriction and use the parent the clock is configured for in the hardware during clk_set_rate(). This requires consumers to rely on the default parent or to configure the parent with clk_set_parent()/assigned-clock-parents on the clocks before calling clk_set_rate().
