From 1d15cb9ce9a220192f672cd32369f8d3c7d3a89b Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 16 Nov 2015 06:51:36 +0100 Subject: [PATCH 001/125] clk: tegra: Add Tegra210 device tree binding Add a header file that defines the clock numbers for Tegra210. It is meant to be included by device trees so that they can refer to the clocks by symbolic name instead of numeric value. Also add the device tree binding documentation which is largely the same as for earlier generations of Tegra. Extracted from a larger patch by Rhyland Klein .

This provides a few benefits. It allows us to specify the frequency of these clocks at the board level instead of hard-coding them in the driver. It allows us to insert an RPM clock in between the consumers of the crystals and the actual clock. And finally, it helps us transition the GCC driver to use RPM clocks when that configuration is enabled.

One of the most important changes is that pll_m isn't to be used as a source for peripherals. Therefore, we need to define the new muxes and new clocks to use those muxes for Tegra210 support. Tegra210 has some differences in the PLLP clock tree: - Four new output clocks: PLLP_OUT_CPU, PLLP_OUT_ADSP, PLLP_OUT_HSIO, and PLLP_OUT_XUSB. - PLLP_OUT2 is fixed at 1/2 the rate of PLLP_VCO. - PLLP_OUT4 is the child of PLLP_OUT_CPU. Update the xusb_hs_src mux and add the xusb_ssp_src mux for Tegra210. Including work by Andrew Bresticker and Bill Huang .

Add callbacks that can be overridden to allow for different ways of calculating rates. Default to _cal_rate when not specified. This patch also includes a new flag which is used to set which method of fixed_mdiv calculation is used. The new method for calculating the fixed divider value for M can be more accurate especially when fractional dividers are in play. This allows for older chipsets to use the existing logic and new generations to use a newer version which may work better for them.

This avoids incorrectly converting pdiv to hw twice and getting the wrong hw value. Also set the input_rate in the freq cfg in _calc_dynamic_ramp_rate while setting all the other fields. In order to prevent regressions on earlier SoC generations, all of the frequency tables need to be updated so that they contain the actual divider values. If they contain hardware values these would be converted to hardware values again, yielding the wrong value.

Starting with Tegra124 PLLM can change rate. Mark PLLM as TEGRA_PLL_FIXED for the generations where it should be. Modify the check in clk_pll_round_rate() and clk_pll_recalc_rate() to allow for the non-fixed version to return the correct rate. Note that there is no change for Tegra20. This is because PLLM is not distinguished in that driver, and adding either the PLLM or FIXED_RATE flags will cause potential problems. PLLM never supported dynamic ramping. On Tegra20 and Tegra30, there is no dynamic ramping at all, and on Tegra114, Tegra124 and Tegra132, only PLLX and PLLC support dynamic ramping, so we can go ahead and remove the specialized pllm_ops.

After commit 4a98da2164cf (regmap-mmio: Use native endianness for read/write, 2015-10-29), the regmap mmio bus will read/write with the __raw_*() IO accessors, instead of using the readl/writel() APIs that do proper byte swapping for little endian devices. So if we're running on a big endian processor and haven't specified the endianness explicitly in the regmap config or in DT, we're going to switch from doing little endian byte swapping to big endian accesses without byte swapping, leading to some confusing results. On my apq8074 dragonboard, this causes the device to fail to boot as we access the clock controller with big endian IO accesses even though the device is little endian. Specify the endianness explicitly so that the regmap core properly byte swaps the accesses for us.

As a workaround, before re-programming the M/N ratio, SW has to ensure the DPLL cannot start an idle state transition. SW can disable DPLL idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request active by setting a dependent clock domain in SW_WKUP. This errata impacts OMAP5 and DRA7 chips, so enable the errata for these.

Pass the width along to _get_table_maxdiv() so that we only return the maximum divider that is valid. This is useful for clocks that want to share the same divider table while limiting the available dividers to some subset of the table depending on the width of the bitfield.

2015 17:31:41 -0800 Subject: [PATCH 055/125] clk: qcom: Add gfx3d ping-pong PLL frequency switching The GPU clocks on msm8996 have three dedicated PLLs, MMPLL2, MMPLL8, and MMPLL9. We leave MMPLL9 at the maximum speed (624 MHz), and we use MMPLL2 and MMPLL8 for the other frequencies. To make switching frequencies faster, we ping-pong between MMPLL2 and MMPLL8 when we're switching between frequencies that aren't the maximum. Implement custom rcg clk ops for this type of frequency switching.

If the APLL works in a high frequency mode, some IPs might hang during soft reset. It appears that we can fix the problem by switching to slow mode before reboot, just like what we did before suspend.

This is the main voltage for all kinds of misc stuff including the memory controller. On these boards it is critically important to make sure that the PWM never ever glitches and never loses its clock. Any glitch could crash the system. Right now there are no users of the PWM regulator and also Linux thinks that the PWM regulator is disabled. Things happen to work because firmware configured the PWM and Linux doesn't touch it. ..and the PWM's clock is marked as "ignore unused". ...but things _stop_ working if we turn off serial console. Why? Because: 1. Serial console shares a parent clock with the PWM (pclk_cpu) 2. If we have no serial console then nobody is holding pclk_cpu on at reboot time. It gets disabled. We need to fix a lot of the above problems, but until we get everything right the cleanest "hack" seems like it is to just keep the "rk_pwm" clock on always.

With sun9i we are supporting the PRCM clocks by using CLK_OF_DECLARE, instead of through a PRCM mfd device and subdevices for each clock and reset control. As such we need a CLK_OF_DECLARE version of the sun8i-a23-apb0-clk driver. Also, build it for sun9i/A80, and not just for configurations with MFD_SUN6I_PRCM enabled.

The dwc2 controllers used create really big number of interrupts in special constellations involving usb-hubs and their number is so high, it can even overwhelm the interrupt handler if the cpu-speed os to low. Right now the PLLs are put into slow-mode in a shutdown syscore_ops callback which means it happens on all reboots (not only the soft-reset ones) and even on poweroff actions. This can result in the system not powering off and getting stuck instead, so we should move the slow-mode change nearer to the actual reboot action. For this we introduce the possiblity to also set a callback that gets called from the restart-handler directly prior to restarting the system and move the shutdown-callback to this new option. With this the slow-mode switch is done only on the necessary reboots and also has a smaller possibility of causing artifacts.

The downstream muxes themselfs are not generic enough to include them directly into the fractional divider, as they have varying sources of parent clocks including not only clocks related to the fractional dividers but other clocks as well. To solve this, allow our clock branches to specify direct child clock- branches in the new child property, let the fractional divider register its downstream mux through this and add a clock notifier that temporarily switches the mux setting when it notices rate changes to the fractional divider.

These clocks divide the rate of a parent which can be selected by setting the proper bits in the clock control register. Previously all these parents where handled by a mux clock. But a mux clock cannot be used because updating clock control register to select parent needs a password to be xor'd with the parent index. This patch get rid of mux clock and make these clocks handle their own parent, allowing them to select the one to use.

While there may be some way to also set that missing property in the inline notation I didn't find it, so to actually fix the issue for now move the sub-definitions into separate declarations that can have their own __initdata properties.

This causes the SolidRun platforms to fail probing the SDHCI1 interface which is connected to the WiFi. Fix this by detecting errno codes, skipping the allocation, and fixing of_clk_gpio_gate_delayed_register_get() to handle a NULL parent_names array.
