2018-03-19clk: qcom: rpmcc: Add support to XO buffered clocksSrinivas Kandagatla
XO is onchip buffer clock to generate 19.2MHz. This patch adds support to 5 XO buffer clocks found on PMIC8921, these buffer clocks can be controlled from external pin or in manual mode.

2017-11-01clk: qcom: Implement RPM clocks for MSM8660/APQ8060Linus Walleij
The RPM clocks were missing for MSM8660/APQ8060. For this to be completed we need to add a special fixed rate RPM clock that is used for the PLL4 on these SoCs. The rest of the clocks are pretty similar to the other supported platforms. The "active" clock pattern is mirrored in all the clocks. I guess that the PLL4 that clocks the LPASS is actually never used as "active only" since the low-power audio subsystem should be left on when the CPU goes to idle, so that it can be used as a stand-alone MP3 player type of device. The PLL4 seems to be enabled only on behalf of the booting LPASS Hexagon - which will cast its own vote once its booted - and as such we only configure the active state (meaning both states will have same configuration). The result is that PLL4 will be on from prepare() to unprepare() regardless of what the application CPU does.

2016-11-23clk: qcom: clk-rpm: Fix clk_hw referencesGeorgi Djakov
Fix the clk_hw references to the actual clocks and add a xlate function to return the hw pointers from the already existing static array. Reported-by: Michael Scott <michael.scott@linaro.org> Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2016-11-10clk: qcom: Add support for RPM ClocksGeorgi Djakov
This adds initial support for clocks controlled by the Resource Power Manager (RPM) processor on some Qualcomm SoCs, which use the qcom_rpm driver to communicate with RPM. Such platforms are apq8064 and msm8960. Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
