| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver. However TSADC is present only on Exynos4210 so on Trats2 board (with Exynos4412 SoC) the exynos-adc driver could not be probed: ERROR: could not get clock /adc@126C0000:adc(0) exynos-adc 126c0000.adc: failed getting clock, err = -2 exynos-adc: probe of 126c0000.adc failed with error -2 Instead on Exynos4x12 SoCs the main clock used by Analog to Digital Converter is located in different register and it is named in datasheet as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock is the same as purpose of TSADC from Exynos4210. The patch adds gate clock for Exynos4x12 using the proper register so backward compatibility is preserved. This fixes the probe of exynos-adc driver on Exynos4x12 boards and allows accessing sensors connected to it on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

|/ | | | | | | | | | | | | | Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Only include clk.h in files that are using it. The clkdev.h header isn't always used either, so remove it and add in slab.h where files were relying on it to include slab for them.

| * 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.
