When we introduced the parent_map tables, we missed to update some of the functions where mapping is translated. Fix this. Signed-off-by: Georgi Djakov --- Changes since v1: * Pass parent map to _freq_tbl_determine_rate() drivers/clk/qcom/clk-rcg.c | 26 -- drivers

[PATCH 1/2] clk: qcom: Fix MSM8916 venus divider value

One of the video codec clock frequencies has incorrect divider value. Fix it. Fixes: 3966fab8b6ab "clk: qcom: Add MSM8916 Global Clock Controller support" Signed-off-by: Georgi Djakov --- drivers/clk/qcom/gcc-msm8916.c |2 +- 1 file changed, 1 insertion(+), 1 deletion(-) di

[PATCH 0/5] Add support for A53 CPU clock

This patchset adds support for the A53 CPU clock to allow CPU frequency scaling. It is used on platforms like Qualcomm's msm8916. Georgi Djakov (4): clk: qcom: Add support for SR2 PLLs clk: qcom: Add support for regmap mux-div clocks clk: qcom: Add A53 clock driver arm64: dts:

[PATCH 3/5] clk: qcom: Add support for regmap mux-div clocks

Add support for hardware that support switching both parent clocks and the divider at the same time. This avoids generating intermediate frequencies from either the old parent clock and new divider or new parent clock and old divider combinations. Signed-off-by: Georgi Djakov --- drivers/clk

[PATCH 4/5] clk: qcom: Add A53 clock driver

Add a driver for the A53 subsystem PLL, so that we can provide higher frequency clocks for use by the system. Signed-off-by: Georgi Djakov --- Documentation/devicetree/bindings/clock/qcom,a53cc | 22 +++ drivers/clk/qcom/Kconfig |8 + drivers/clk/qcom/Makefile

[PATCH 5/5] arm64: dts: qcom: msm8916: Add A53 DT node

Add nodes for the A53 clocks and apcs, so that the driver can probe and register the clocks. Signed-off-by: Georgi Djakov --- arch/arm64/boot/dts/qcom/msm8916.dtsi | 12 1 file changed, 12 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/msm8916.dtsi b/arch/arm64/boot/dts

[PATCH v2 0/5] Add support for more MSM8916 clocks

This patchset adds support for the iommu, gpu and audio clocks on the MSM8916 platforms. Changes since v1: * Added a set of ops for read-only RCGs and RCGs with shared branches. Patchset based on clk-next. Georgi Djakov (5): clk: qcom: Add support for read-only rcg2 ops clk: qcom: Add

[PATCH v2 3/5] clk: qcom: Add support for RCGs with shared branches

Some root clock generators may have child branches that are controlled by different CPUs. These RCGs require special operations. Signed-off-by: Georgi Djakov --- drivers/clk/qcom/clk-rcg.h |1 + drivers/clk/qcom/clk-rcg2.c | 64 +++ 2 files changed

[PATCH v2 5/5] clk: qcom: Add MSM8916 audio clocks

Add support for the msm8916 audio clocks. This includes core bus, low-power audio and codec clocks. They are required for audio playback. Signed-off-by: Georgi Djakov --- drivers/clk/qcom/gcc-msm8916.c | 388 ++ include/dt-bindings/clock/qcom,gcc-msm8916.h

[PATCH v2 1/5] clk: qcom: Add support for read-only rcg2 ops

Some root clock generators can be controlled by other processors. In this case modifying them is not recommended. By using the read-only operations, the child clocks will be able to get information about their parent - like rate etc. Suggested-by: Stephen Boyd Signed-off-by: Georgi Djakov
