| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clock With the addition of the new Samsung specific cpu-clock type, the arm clock can be represented as a cpu-clock type. Add the CPU clock configuration data and instantiate the CPU clock type for Exynos4210. Changes by Bartlomiej: - fixed issue with wrong dividers being setup by Common Clock Framework (by an addition of CLK_RECALC_NEW_RATES clock flag to mout_apll clock, without this change cpufreq-dt driver showed ~10 mA larger energy consumption when compared to cpufreq-exynos one when "performance" cpufreq governor was used on Exynos4210 SoC based Origen board), this was probably meant to be workarounded by use of CLK_GET_RATE_NOCACHE and CLK_DIVIDER_READ_ONLY clock flags in the original patchset (in "[PATCH v12 6/6] clk: samsung: remove unused clock aliases and update clock flags") but using these flags is not sufficient to fix the issue observed - removed Exynos5250 and Exynos5420 support for now Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Mike Turquette <mturquette@linaro.org> Cc: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>
| * clk: samsung: add infrastructure to register cpu clocksThomas Abraham2015-06-203-1/+423
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CPU clock provider supplies the clock to the CPU clock domain. The composition and organization of the CPU clock provider could vary among Exynos SoCs. A CPU clock provider can be composed of clock mux, dividers and gates. This patch defines a new clock type for CPU clock provider and adds infrastructure to register the CPU clock providers for Samsung platforms. Changes by Bartlomiej: - fixed issue with setting lower dividers before the parent clock speed was lowered (the issue resulted in lockup on Exynos4210 SoC based Origen board when "ondemand" cpufreq governor was stress tested) - fixed missing spin_unlock on error in exynos_cpuclk_post_rate_change() problem by moving cfg_data search outside of the spin locked area - removed leftover kfree() in exynos_register_cpu_clock() that could result in dereferencing the NULL pointer on error - moved spin_lock earlier in exynos_cpuclk_pre_rate_change() to cover reading of E4210_SRC_CPU and E4210_DIV_CPU1 registers - added missing "last chance" checks to wait_until_divider_stable() and wait_until_mux_stable() (needed in case that IRQ handling took long time to proceed and resulted in function printing incorrect error message about timeout) - moved E4210_CPU_DIV[0,1]() macros just before their only users, this resulted in moving them from patch #2 to patch #3/6 ("clk: samsung: exynos4: add cpu clock configuration data and instantiate cpu clock") - removed E5250_CPU_DIV[0,1](), E5420_EGL_DIV0() and E5420_KFC_DIV() macros for now - added my Copyrights to drivers/clk/samsung/clk-cpu.c Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Mike Turquette <mturquette@linaro.org> Cc: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ae43b3289186 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12") added pm support for the pl330 dma driver but it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated during suspend and this in turn makes its parent clock aclk266_g2d to be gated. But the clock needs to be ungated prior suspend to allow the system to be suspend and resumed correctly. Add GATE_BUS_TOP register to the list of registers to be restored when the system enters into a suspend state so aclk266_g2d will be ungated. Thanks to Abhilash Kesavan for figuring out that this was the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | The statement static const char *name[]; defines a modifiable array of pointers to constant chars. That is *name[0] = 'f'; is forbidden, but name[0] = "f"; is not. So marking an array that is defined as above with __initconst is wrong. Either an additional const must be added such that the whole definition reads: static const char *const name[] __initconst; or where this is not possible __initdata must be used.

Additionally the framework core underwent a bit of surgery with two major changes: - The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. - The addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage. We think we fixed it all up but for this reason there are lots of last minute commits trying to undo the damage" * tag 'clk-for-linus-3.20' of git://git.linaro.org/people/mike.turquette/linux: (113 commits) clk: Only recalculate the rate if needed Revert "clk: mxs: Fix invalid 32-bit access to frac registers" clk: qoriq: Add support for the platform PLL powerpc/corenet: Enable CLK_QORIQ clk: Replace explicit clk assignment with __clk_hw_set_clk clk: Add __clk_hw_set_clk helper function clk: Don't dereference parent clock if is NULL MIPS: Alchemy: Remove bogus args from alchemy_clk_fgcs_detr clkdev: Always allocate a struct clk and call __clk_get() w/ CCF clk: shmobile: div6: Avoid division by zero in .round_rate() clk: mxs: Fix invalid 32-bit access to frac registers clk: omap: compile legacy omap3 clocks conditionally clkdev: Export clk_register_clkdev clk: Add rate constraints to clocks clk: remove clk-private.h pci: xgene: do not use clk-private.h arm: omap2+ remove dead clock code clk: Make clk API return per-user struct clk instances clk: tegra: Define PLLD_DSI and remove dsia(b)_mux clk: tegra: Add support for the Tegra132 CAR IP block ...
