clk: versatile: mask VCO bits before writing

2016-02-10T17:56:31Z

The Versatile syscon ICST driver OR:s the bits into place but forgets to mask the previous value, making the code only work if the register is zero or giving haphazard results. Mask the 19 bits used by the Versatile syscon interface register. Regression caused and now fixed by yours truly.

Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

ARM: versatile: switch to DT only booting and remove legacy code

2015-12-15T22:53:21Z

With DT support for clocks, irqchips, timers, and PCI now in place, DT based booting has feature parity with non-DT legacy boot. The final piece is actually enabling common clock support on Versatile. Enabling full DT support requires either removing the old Versatile clock code, updating the legacy boot to use the common clock code, or making DT and legacy boot mutually exclusive. Given that removing legacy boot code is the goal anyway, I am going with the 1st option. Signed-off-by: Rob Herring Cc: Russell King Cc: Linus Walleij Cc: Mike Turquette Signed-off-by: Arnd Bergmann

clk: versatile-icst: add device tree support

2015-12-15T08:42:50Z

This adds support for the ARM syscon ICST clocks to initialized directly from the device tree syscon node on ARM Integrator, Versatile and RealView reference designs. Cc: Michael Turquette Cc: Stephen Boyd Cc: linux-clk@vger.kernel.org Signed-off-by: Linus Walleij

clk: versatile-icst: refactor to allocate regmap separately

2015-12-15T08:42:49Z

Break out the registration function so it creates a regmap and pass to the setup function, so the latter can be shared with a device tree probe function that already has a regmap. Cc: Michael Turquette Cc: Stephen Boyd Cc: linux-clk@vger.kernel.org Signed-off-by: Linus Walleij

clk: versatile-icst: convert to use regmap

2015-12-15T08:42:48Z

Instead of passing around register bases, pass around a regmap in this driver. This refactoring make things so much easier when we later want to manage an ICST that is part of a syscon. Cc: Michael Turquette Cc: Stephen Boyd Cc: linux-clk@vger.kernel.org Signed-off-by: Linus Walleij

clk/realview: stop using machine headers

2015-12-15T08:41:33Z

In order to move realview into multiplatform, we have to prevent device drivers from accessing the machine header files. In case of the clk driver, this is very simple, we just copy the small set of register definitions into the driver that needs them. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Walleij

clk: versatile: remove unneeded error message

2015-11-20T17:17:18Z

If kzalloc fails we will already have many messages in the log and we do not need another message to know that kzalloc for sp810 has failed. Signed-off-by: Sudip Mukherjee Signed-off-by: Stephen Boyd

clk: versatile: fix memory leak

2015-11-18T22:25:48Z

If of_clk_parent_fill() fails then we printed an error message and returned. But we missed freeing sp810. Signed-off-by: Sudip Mukherjee Signed-off-by: Stephen Boyd
