| * phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.Peter Griffin2015-01-301-19/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy365 phy driver to access sysconfig register offsets via syscfg dt property. This is because the reg property should not be mixing address spaces like it does currently for miphy365. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. This patch breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it. This change has been done as a single atomic commit to ensure it is bisectable.

| * phy: exynos-video-mipi: Fix regression by adding support for PMU regmapSylwester Nawrocki2015-01-301-32/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the Exynos Power Management Unit (PMU) driver was converted to the platform device driver in commit 14fc8b93d47323561edf5d482 ("ARM: EXYNOS: Add platform driver support for Exynos PMU") and then PMU device nodes added to Exynos4 DTs in commit 7b9613aca42a5522d269 ("ARM: dts: add PMU syscon node for exynos4") the mipi video phy driver started failing probing, due to overlapping memory mapped register region resources. Now all the Exynos peripheral devices which have registers in the PMU region are supposed to use the regmap provided by the syscon driver. So support for regmap is added in this patch, this unfortunately creates yet another indirection into that supposedly trivial driver. The additional mutex is required because single register is used by PHY pairs (they share bit in a register). An improvement here could be to allow a PHY instance be created with a driver custom mutex, which would then be common for each PHY pair. This would eliminate one of 3 mutexes which need to be taken in the phy_power_on/ phy_power_off code path. However, I tried to keep this bug fix patch possibly simple. This change is needed to make MIPI DSI displays and MIPI CSI-2 camera sensors working again on Exynos4 boards.

This is because other phy's (miphy28, miphy365) have a combination of memory mapped registers and sysconfig control regs, and we shouldn't be mixing address spaces in the reg property. In addition we would ideally like the sysconfig offsets to be passed via DT in a uniform way. This new method will also allow us to support devices which have sysconfig registers in different banks more easily and it is also analagous to how keystone and bcm7745 platforms pass there syscon offsets in DT. This breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Failed test case: Boot without SATA drive connected. Suspend/resume the board and then connect SATA drive. It fails to enumerate. Due to Errata i783 "SATA Lockup After SATA DPLL Unlock/Relock" we can't allow SATA DPLL to be in the unlocked state. The SATA refclk (sata_ref_clk) is the source of the SATA_DPLL. This clock is being controlled only by the AHCI SATA driver and is shut off during system suspend (if the SATA drive was not already attached) causing the SATA DPLL to be unlocked and so causing errata i783. To prevent sata_ref_clk from being disabled, we add the control of this clock to the SATA PHY driver and prevent it from being disabled. This also fixes the issue of SATA not working on OMAP5/DRA7 when AHCI platform driver is built as a module. NOTE: Device tree changes also required for OMAP5 & DRA7.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On system suspend, the runtime_suspend() driver hook doesn't get called for USB phy and so the clocks are not disabled in the driver. This causes the L3INIT_960M_GFCLK and L3INIT_480M_GFCLK to remain active on the DRA7 platform while in system suspend. In case of pcie-phy, the runtime_suspend hook gets called after the suspend hook so we introduce a flag phy->enabled to keep track if our clocks are enabled or not to prevent multiple enable/disables. Add suspend/resume hooks to the driver. Move enabling/disabling clock code into helper functions.

As of DRA74x silicon rev 1.1, pcie_pcs register definition has changed. Bits 16-23 are used to configure delay values for *both* phy1 and phy2. Hence phyid is no longer required. So, drop id field from ti_pipe3 structure and its subsequent references for configuring pcie_pcs register. Also, pcie_pcs register now needs to be configured with delay value of 0x96 at bit positions 16-23. See register description of CTRL_CORE_PCIE_PCS in ARM572x TRM, SPRUHZ6, October 2014, section 18.5.2.2, table 18-1804. This is needed to ensure Gen2 cards are enumerated consistently.

* | phy: miphy365x: Pass sysconfig register offsets via syscfg dt property.Peter Griffin2015-01-111-19/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the miphy365 phy driver to access sysconfig register offsets via syscfg dt property. This is because the reg property should not be mixing address spaces like it does currently for miphy365. This change then also aligns us to how other platforms such as keystone and bcm7445 pass there syscon offsets via DT. This patch breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it. This change has been done as a single atomic commit to ensure it is bisectable.

|/ | | | | | | | | | | | | | | | | | | | | | Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161, update the phy driver to not use the reg property to access the sysconfig register offsets. This is because other phy's (miphy28, miphy365) have a combination of memory mapped registers and sysconfig control regs, and we shouldn't be mixing address spaces in the reg property. In addition we would ideally like the sysconfig offsets to be passed via DT in a uniform way. This new method will also allow us to support devices which have sysconfig registers in different banks more easily and it is also analagous to how keystone and bcm7745 platforms pass there syscon offsets in DT. This breaks DT compatibility, but this platform is considered WIP, and is only used by a few developers who are upstreaming support for it.

Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.
