2020-09-22clk: samsung: exynos4: mark 'chipid' clock as CLK_IGNORE_UNUSEDMarek Szyprowski1-2/+2
The ChipID IO region has it's own clock, which is being disabled while scanning for unused clocks. It turned out that some CPU hotplug, CPU idle or even SOC firmware code depends on the reads from that area. Fix the mysterious hang caused by entering deep CPU idle state by ignoring the 'chipid' clock during unused clocks scan, as there are no direct clients for it which will keep it enabled.

2020-09-21clk: tegra: Always program PLL_E when enabledThierry Reding1-3/+0
Commit bff1cef5f23a ("clk: tegra: Don't enable already enabled PLLs") added checks to avoid enabling PLLs that have already been enabled by the bootloader. However, the PLL_E configuration inherited from the bootloader isn't necessarily the one that is needed for the kernel. This can cause SATA to fail like this: [ 5.310270] phy phy-sata.6: phy poweron failed --> -110 [ 5.315604] tegra-ahci 70027000.sata: failed to power on AHCI controller: -110 [ 5.323022] tegra-ahci: probe of 70027000.sata failed with error -110 Fix this by always programming the PLL_E. This ensures that any mis- configuration by the bootloader will be overwritten by the kernel.

BPLL clock must not be disabled because it is needed for proper DRAM operation. This is normally handled by respective memory devfreq driver, but when that driver is not yet probed or its probe has been deferred the clock might get disabled what causes board hang. Fix this by calling clk_prepare_enable() directly from the clock provider driver.

2020-09-10clk: versatile: Add of_node_put() before return statementSumera Priyadarsini1-1/+3
Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node, however when control is transferred from the middle of the loop, as in the case of a return or break or goto, there is no decrement thus ultimately resulting in a memory leak. Fix a potential memory leak in clk-impd1.c by inserting of_node_put() before a return statement. Issue found with Coccinelle.

2020-08-03clk: bcm2835: Do not use prediv with bcm2711's PLLsNicolas Saenz Julienne1-4/+21
Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL feedback loop. Bypass it by zeroing fb_prediv_mask when running on bcm2711. Note that, since the prediv configuration bits were re-purposed, this was triggering miscalculations on all clocks hanging from the VPU clock, notably the aux UART, making its output unintelligible.

2020-07-27clk: tegra: pll: Improve PLLM enable-state detectionDmitry Osipenko1-5/+15
Power Management Controller (PMC) can override the PLLM clock settings, including the enable-state. Although PMC could only act as a second level gate, meaning that PLLM needs to be enabled by the Clock and Reset Controller (CaR) anyways if we want it to be enabled. Hence, when PLLM is overridden by PMC, it needs to be enabled by CaR and ungated by PMC in order to be functional. Please note that this patch doesn't fix any known problem, and thus, it's merely a minor improvement.
