* clk: qcom: gdsc: Fix handling of hw control enable/disableRajendra Nayak2017-01-261-13/+45
| | | | | | | | | | | | | | | | | | | | | Once a gdsc is brought in and out of HW control, there is a power down and up cycle which can take upto 1us. Polling on the gdsc status immediately after the hw control enable/disable can mislead software/firmware to belive the gdsc is already either on or off, while its yet to complete the power cycle. To avoid this add a 1us delay post a enable/disable of HW control mode. Also after the HW control mode is disabled, poll on the status to check gdsc status reflects its 'on' before force disabling it in software.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This is necessary to enable clocking of the external bus interface so that peripherals on it can be mounted. These two clocks are simple gated branch clocks. In the vendor tree clock-8x60, these clocks have some kind of dependency, the EBI2 clock has .depends = &ebi2_2x_clk.c, what this means is undocumented, it doesn't seem like there is a parent/child relationship, so the solution I chose was to just have the EBI2 driver get and enable both clocks.

* clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPMArchit Taneja2016-05-121-32/+0
| | | | | | | | | | | | | | | | The branch clocks MMSS_MMAGIC_AXI_CLK and MMAGIC_BIMC_AXI_CLK are controlled by RPM when the APPs processor enable or disable the RPM_MMAXI_CLK. During the boot sequence, someone can enable the RPM_MMAXI_CLK, resulting in register status bits showing that these clocks are enabled, our clock driver may look at the enabled status of these clocks and try to disable them since it thinks they are unused. Don't make the clock driver touch these clocks. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
* clk: qcom: msm8916: Fix crypto clock flagsAndy Gross2016-05-061-0/+2
| | | | | | | | | | This patch adds the CLK_SET_RATE_PARENT flag for the crypto core and ahb blocks. Without this flag, clk_set_rate can fail for certain frequency requests.

| | | | | | | | Drivers for these don't exist yet so we will add them as fixed clocks so we don't BUG() if we change clocks that reference these clocks. Signed-off-by: Matthew McClintock <mmcclint@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
