2023-07-19clk: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2016-12-28clk: qcom: ipq4019: Add the cpu clock frequency change notifierAbhishek Sahu1-1/+39
The current driver code gives the crash or gets hang while switching the CPU frequency some time. The APSS CPU Clock divider is not glitch free so it the APPS clock need to be switched for stable clock during the change. This patch adds the frequency change notifier for APSS CPU clock. It changes the parent of this clock to stable PLL FEPLL500 for PRE_RATE_CHANGE event. This event will be generated before actual clock set operations. The clock set operation will again change its corresponding parent by getting the same from frequency table.

2016-12-22clk: qcom: ipq4019: Add all the frequencies for apss cpuAbhishek Sahu1-2/+12

2016-12-22clk: qcom: ipq4019: Add the nodes for pcnocAbhishek Sahu1-0/+39
The current ipq4019 clock driver does not have the node for PCNOC so this patch adds and registers the PCNOC clock nodes. This PCNOC clock is critical and should not be turned off so setting CRITICAL flag also. Signed-off-by: Abhishek Sahu <absahu@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2016-12-22clk: qcom: ipq4019: Add the apss cpu pll divider clock nodeAbhishek Sahu1-0/+132
The current ipq4019 clock driver does not have support for all the frequency supported by APSS CPU. APSS CPU frequency is provided with APSS CPU PLL divider which divides down the VCO frequency. This divider is nonlinear and specific to IPQ4019 so the standard divider code cannot be used for this.

2016-12-22clk: qcom: ipq4019: remove fixed clocks and add pll clocksAbhishek Sahu1-11/+243
The current ipq4019 clock driver registered the PLL clocks and dividers as fixed clock. These fixed clock needs to be removed from driver probe function and same need to be registered with clock framework. These PLL clocks should be programmed only once and the same are being programmed already by the boot loader so the set rate operation is not required for these clocks. Only the rate can be calculated by clock operations in clock driver file so this patch adds the same. The PLL takes the reference clock from XO and generates the intermediate VCO frequency. This VCO frequency will be divided down by different PLL internal dividers. Some of the PLL internal dividers are fixed while other are programmable.
