We should always check if the bus is free, independently if it is a read or write. It should be done before the first message, though. After that, we ourselves keep the bus busy. Remove a 'ret' assignment which only silenced a build warning. Signed-off-by:

The i2c-eg20t driver is for a companion chip to the Intel Atom E600 series processors. These are 32-bit x86 processors so the driver is only needed on X86_32. Add COMPILE_TEST as an alternative, so that the driver can still be build-tested elsewhere. Signed-off-by:

Newer SoCs have so fast input clocks that the ICCL/H registers only count every second clock to have a meaningful 9-bit range. The driver was already prepared for that happening, but didn't use it so far. Add the proper DT configuration for SoCs that need it. Signed-off-by:

Due to misconfiguration, it can happen that the calculated timing parameters are out of range. Bail out if that happens. We can also simplify some logic later because of the verified value. Also, make the printouts of the values more precise by adding the hex-prefixes. Signed-off-by:

HSI2C module on Exynos5260 differs from current modules in following ways: 1. HSI2C on Exynos5260 has fifo_depth of 16bytes 2. Module needs to be reset as a part of init sequence. Hence, Following changes are involved. 1. Add a new compatible string and Updates the Documentation dt bindings. 2. Introduce a variant struct to support the changes in H/W 3. Reset the module during init. Thus, bringing the module back to default state irrespective of what firmware did with it. Signed-off-by:

Ulf Hansson authored
For !CONFIG_PM_RUNTIME, the device were never put back into active state while resuming. For CONFIG_PM_RUNTIME, we blindly trusted the device to be inactive while we were about to handle it at suspend late, which is just too optimistic. Even if the driver uses pm_runtime_put_sync() after each tranfer to return it's runtime PM resources, there are no guarantees this will actually mean the device will inactivated. The reason is that the PM core will prevent runtime suspend during system suspend, and thus when a transfer occurs during the early phases of system suspend the device will be kept active after the transfer. To handle both issues above, use pm_runtime_force_suspend|resume() from the system suspend|resume callbacks. Signed-off-by:

Pull two powerpc fixes from Ben Herrenschmidt: "Here are a couple of fixes for 3.15. One from Anton fixes a nasty regression I introduced when trying to fix a loss of irq_work whose consequences is that we can completely lose timer interrupts on a CPU... not pretty. The other one is a change to our PCIe reset hook to use a firmware call instead of direct config space accesses to trigger a fundamental reset on the root port. This is necessary so that the FW gets a chance to disable the link down error monitoring, which would otherwise trip and cause subsequent fatal EEH error" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: irq work racing with timer interrupt can result in timer interrupt hang powerpc/powernv: Reset root port in firmware
