2016-11-18clk: qoriq: Don't allow CPU clocks higher than starting valueScott Wood1-5/+8
commit 7c1c5413a7bdf1c9adc8d979521f1b8286366aef upstream. The boot-time frequency of a CPU is considered its rated maximum, as we have no other source of such information. However, this was previously only used for chips with 80% restrictions on secondary PLLs. This usually wasn't a problem because most chips/configs boot with a divider of /1, with other dividers being used only for dynamic frequency reduction. However, at least one config (LS1021A at less than 1 GHz) uses a different divider for top speed. This was causing cpufreq to set a frequency beyond the chip's rated speed. This is fixed by applying a 100%-of-initial-speed limit to all CPU PLLs, similar to the existing 80% limit that only applied to some.

2016-10-31clk: divider: Fix clk_divider_round_rate() to use clk_readl()Geert Uytterhoeven1-1/+1
commit 2cf9a57811bddb6fa6b0f8d7376da164d5534813 upstream. clk-divider uses clk_readl()/clk_writel() everywhere, except in clk_divider_round_rate(), where plain readl() is used. Change this to clk_readl(), as it makes a difference on powerpc.

commit ec7957a6aa0aaf981fb8356dc47a2cdd01cde03c upstream. Despite care take to allocate clocks state containers the SP810 driver actually just supports creating one instance: all clocks registered for every instance will end up with the exact same name and __clk_init() will fail. Rename the timclken<0> .. timclken<n> to sp810_<instance>_<n> so every clock on every instance gets a unique name. This is necessary for the RealView PBA8 which has two SP810 blocks: the second block will not register its clocks unless every clock on every instance is unique and results in boot logs like this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at ../drivers/clk/versatile/clk-sp810.c:137 clk_sp810_of_setup+0x110/0x154() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.5.0-rc2-00030-g352718fc39f6-dirty #225 Hardware name: ARM RealView Machine (Device Tree Support) [<c00167f8>] (unwind_backtrace) from [<c0013204>] (show_stack+0x10/0x14) [<c0013204>] (show_stack) from [<c01a049c>] (dump_stack+0x84/0x9c) [<c01a049c>] (dump_stack) from [<c0024990>] (warn_slowpath_common+0x74/0xb0) [<c0024990>] (warn_slowpath_common) from [<c0024a68>] (warn_slowpath_null+0x1c/0x24) [<c0024a68>] (warn_slowpath_null) from [<c051eb44>] (clk_sp810_of_setup+0x110/0x154) [<c051eb44>] (clk_sp810_of_setup) from [<c051e3a4>] (of_clk_init+0x12c/0x1c8) [<c051e3a4>] (of_clk_init) from [<c0504714>] (time_init+0x20/0x2c) [<c0504714>] (time_init) from [<c0501b18>] (start_kernel+0x244/0x3c4) [<c0501b18>] (start_kernel) from [<7000807c>] (0x7000807c) ---[ end trace cb88537fdc8fa200 ]--- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Pawel Moll <pawel.moll@arm.com> Fixes: 6e973d2c4385 "clk: vexpress: Add separate SP810 driver" Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-05-11clk-divider: make sure read-only dividers do not write to their registerHeiko Stuebner3-3/+14
commit 50359819794b4a16ae35051cd80f2dab025f6019 upstream. Commit e6d5e7d90be9 ("clk-divider: Fix READ_ONLY when divider > 1") removed the special ops struct for read-only clocks and instead opted to handle them inside the regular ops. On the rk3368 this results in breakage as aclkm now gets set a value. While it is the same divider value, the A53 core still doesn't like it, which can result in the cpu ending up in a hang. The reason being that "ACLKENMasserts one clock cycle before the rising edge of ACLKM" and the clock should only be touched when STANDBYWFIL2 is asserted. To fix this, reintroduce the read-only ops but do include the round_rate callback. That way no writes that may be unsafe are done to the divider register in any case. The Rockchip use of the clk_divider_ops is adapted to this split again, as is the nxp, lpc18xx-ccu driver that was included since the original commit. On lpc18xx-ccu the divider seems to always be read-only so only uses the new ops now.

2016-03-04clk: exynos: use irqsave version of spin_lock to avoid deadlock with irqsMarek Szyprowski1-4/+6
commit 6b4feaea251a97bf08c7d41eabdec07f63a11073 upstream. It is allowed to enable/disable clocks from interrupts, so common Exynos ARM clock management code for CPUfreq should use 'irqsave' version of spin_lock calls to avoid potential deadlock caused by spin_lock recursion. The same spin_lock is used by gate/mux clocks during enable/disable calls. This deadlock, can be reproduced by enabling CPUfreq (ondemand or userspace) and decoding video with s5p-mfc driver.

2015-12-03clk: sunxi: pll2: Fix clock running too fastMaxime Ripard1-18/+5
Contrary to what the datasheet says, the pre divider doesn't seem to be incremented by one in the PLL2, but just uses the value from the register, with 0 being a bypass. This fixes the audio playing too fast. Since we now have the same pre-divider flags, and the only difference with the A10 is the post-divider offset, also remove the structure to just pass the offset as an argument.

2015-12-02ARM: imx: clk-vf610: fix SAI clock treeStefan Agner1-4/+4
The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

The common clk implementation for MMP broke without anyone noticing when we stopped including linux/clk.h from the clk-provider header.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The majority of the changes are driver updates and new device support. The core framework is mostly unchanged this time around, with only a couple patches to expose a clk provider API and make getting clk parent names from DT more robust. Driver updates: - Support for clock controllers found on Broadcom Northstar SoCs and bcm2835 SoC - Support for Allwinner audio clocks - A few cleanup patches for Tegra drivers and support for the highest DFLL frequencies on Tegra124 - Samsung exynos7 fixes and improvements - i.Mx SoC updates to add a few missing clocks and keep debug uart clocks on during kernel intialization - Some mediatek cleanups and support for more subsystem clocks - Support for msm8916 gpu/audio clocks and qcom's GDSC power domain controllers - A new driver for the Silabs si514 clock chip" * tag 'clk-for-linus-20151104' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (143 commits) clk: qcom: msm8960: Fix dsi1/2 halt bits clk: lpc18xx-cgu: fix potential system hang when disabling unused clocks clk: lpc18xx-ccu: fix potential system hang when disabling unused clocks clk: Add clk_hw_is_enabled() for use by clk providers clk: Add stubs for of_clk_*() APIs when CONFIG_OF=n clk: versatile-icst: fix memory leak clk: Remove clk_{register,unregister}_multiplier() clk: iproc: define Broadcom NS2 iProc clock binding clk: iproc: define Broadcom NSP iProc clock binding clk: ns2: add clock support for Broadcom Northstar 2 SoC clk: iproc: Separate status and control variables clk: iproc: Split off dig_filter clk: iproc: Add PLL base write function clk: nsp: add clock support for Broadcom Northstar Plus SoC clk: iproc: Add PWRCTRL support clk: cygnus: Convert all macros to all caps ARM: cygnus: fix link failures when CONFIG_COMMON_CLK_IPROC is disabled clk: imx31: add missing of_node_put clk: imx27: add missing of_node_put clk: si5351: add missing of_node_put ...
