git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull module_platform_driver replacement from Paul Gortmaker: "Replace module_platform_driver with builtin_platform driver in non modules. We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the <module.h> which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of <module.h> during a pending header cleanup. So we convert them here vs adding an include of <module.h> to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance
2015-07-01soc: qcom: spm: Fix idle on THUMB2 kernelsStephen Boyd1-1/+1
The ifc6410 firmware always enters the kernel in ARM state from deep idle. Use the cpu_resume_arm() wrapper instead of cpu_resume() to property switch into the THUMB2 state when we wake up from idle. This fixes a problem reported by Kevin Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2 kernel because the platform's firmware always enters the kernel in ARM mode from deep idle states.

This file depends on Kconfig SOC_REALVIEW which is a bool, so we use the appropriate registration function, which avoids us relying on an implicit inclusion of <module.h> which we are doing currently. While this currently works, we really don't want to be including the module.h header in non-modular code, which we'd be forced to do, pending some upcoming code relocation from init.h into module.h. So we fix it now by using the non-modular equivalent.

2015-06-01drivers: soc: sunxi: Introduce SoC driver to map SRAMsMaxime Ripard5-0/+297
The Allwinner SoCs have a handful of SRAM that can be either mapped to be accessible by devices or the CPU. That mapping is controlled by an SRAM controller, and that mapping might not be set by the bootloader, for example if the device wasn't used at all, or if we're using solutions like the U-Boot's Falcon Boot. We could also imagine changing this at runtime for example to change the mapping of these SRAMs to use them for suspend/resume or runtime memory rate change, if that ever happens. These use cases require some API in the kernel to control that mapping, exported through a drivers/soc driver. This driver also implement a debugfs file that shows the SRAM found in the system, the current mapping and the SRAM that have been claimed by some drivers in the kernel.

2015-05-27soc: mediatek: PMIC wrap: Fix register state machine handlingSascha Hauer1-10/+2
When the PMIC wrapper state machine has read a register it goes into the "wait for valid clear" (vldclr) state. The state machine stays in this state until the VLDCLR bit is written to. We should write this bit after reading a register because the SCPSYS won't let the system go into suspend as long as the state machine waits for valid clear. Since now we never leave the state machine in vldclr state we no longer have to check for this state on pwrap_read/pwrap_write entry and can remove the corresponding code.

2015-05-27soc: mediatek: PMIC wrap: Fix clock rate handlingSascha Hauer1-35/+7
replace chipselect extension values based on SPI clock with hardcoded SoC specific values. The PMIC wrapper has the ability of extending the chipselects by configurable amounts of time. We configured the values based on the rate of SPI clock, but this is wrong. The delays should be configured based on the internal PMIC clock that latches the values from the SPI bus to the internal PMIC registers. By default this clock is 24MHz. Other clock frequencies are for debugging only and can be removed from the driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>

2015-04-28ARM: qcom: Add Subsystem Power Manager (SPM) driverLina Iyer3-0/+393
SPM is a hardware block that controls the peripheral logic surrounding the application cores (cpu/l$). When the core executes WFI instruction, the SPM takes over the putting the core in low power state as configured. The wake up for the SPM is an interrupt at the GIC, which then completes the rest of low power mode sequence and brings the core out of low power mode. The SPM has a set of control registers that configure the SPMs individually based on the type of the core and the runtime conditions. SPM is a finite state machine block to which a sequence is provided and it interprets the bytes and executes them in sequence. Each low power mode that the core can enter into is provided to the SPM as a sequence. Configure the SPM to set the core (cpu or L2) into its low power mode, the index of the first command in the sequence is set in the SPM_CTL register. When the core executes ARM wfi instruction, it triggers the SPM state machine to start executing from that index. The SPM state machine waits until the interrupt occurs and starts executing the rest of the sequence until it hits the end of the sequence. The end of the sequence jumps the core out of its low power mode. Add support for an idle driver to set up the SPM to place the core in Standby or Standalone power collapse mode when the core is idle.

This adds support for the PMIC wrapper found on MediaTek MT8135 and MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these are currently not supported. On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via SPI. The SPI master interface is not directly visible to the CPU, but only through the PMIC wrapper inside the SoC. The communication between the SoC and the PMIC can optionally be encrypted. Also a non standard Dual IO SPI mode can be used to increase speed. The MT8135 also supports a special feature named "IP Pairing". With IP Pairing the pins of some SoC internal peripherals can be on the PMIC. The signals of these pins are routed over the SPI bus using the pwrap bridge. Because of these optional non SPI conform features the PMIC driver is not implemented as a SPI bus master driver.

This adds a device tree controlled option to enable PMC-based thermal reset in overheating situations. Thermtrip is supported on Tegra30, Tegra114 and Tegra124. The thermal reset only works when the thermal sensors are calibrated, so a soctherm driver is also required. The thermtrip event is triggered by the soctherm block, and all soctherm sensors default to showing a temperature of zero Celsius before they are initialized.

They have an open source userspace built on top of this interface, and the code looks as good as it was going to get out of tree. - Initial atomic modesetting work The need for an atomic modesetting interface to allow userspace to try and send a complete set of modesetting state to the driver has arisen, and been suffering from neglect this past year. No more, the start of the common code and changes for msm driver to use it are in this tree. Ongoing work to get the userspace ioctl finished and the code clean will probably wait until next kernel. - DisplayID 1.3 and tiled monitor exposed to userspace. Tiled monitor property is now exposed for userspace to make use of. - Rockchip drm driver merged. - imx gpu driver moved out of staging Other stuff: - core: panel - MIPI DSI + new panels. expose suggested x/y properties for virtual GPUs - i915: Initial Skylake (SKL) support gen3/4 reset work start of dri1/ums removal infoframe tracking fixes for lots of things. - nouveau: tegra k1 voltage support GM204 modesetting support GT21x memory reclocking work - radeon: CI dpm fixes GPUVM improvements Initial DPM fan control - rcar-du: HDMI support added removed some support for old boards slave encoder driver for Analog Devices adv7511 - exynos: Exynos4415 SoC support - msm: a4xx gpu support atomic helper conversion - tegra: iommu support universal plane support ganged-mode DSI support - sti: HDMI i2c improvements - vmwgfx: some late fixes. - qxl: use suggested x/y properties" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (969 commits) drm: sti: fix module compilation issue drm/i915: save/restore GMBUS freq across suspend/resume on gen4 drm: sti: correctly cleanup CRTC and planes drm: sti: add HQVDP plane drm: sti: add cursor plane drm: sti: enable auxiliary CRTC drm: sti: fix delay in VTG programming drm: sti: prepare sti_tvout to support auxiliary crtc drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off} drm: sti: fix hdmi avi infoframe drm: sti: remove event lock while disabling vblank drm: sti: simplify gdp code drm: sti: clear all mixer control drm: sti: remove gpio for HDMI hot plug detection drm: sti: allow to change hdmi ddc i2c adapter drm/doc: Document drm_add_modes_noedid() usage drm/i915: Remove '& 0xffff' from the mask given to WA_REG() drm/i915: Invert the mask and val arguments in wa_add() and WA_REG() drm: Zero out DRM object memory upon cleanup drm/i915/bdw: Fix the write setting up the WIZ hashing mode ...

2014-09-26soc: add driver for the ARM RealViewLinus Walleij5-0/+157
This adds a SoC driver to be used by the ARM RealView reference boards. We create the "versatile" directory to hold the different ARM reference designs as per the pattern of the clk directory layout. The driver utilze the syscon to get to the register needed. After this we can use sysfs to get at some SoC properties on RealView DT variants like this: > cd /sysbus/soc/devices/soc0 > ls board family machine power subsystem build fpga manufacturer soc_id uevent > cat family Versatile > cat fpga Multi-layer AXI > cat board HBI-0147 > cat build 03 Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Conflicts: drivers/soc/Kconfig drivers/soc/Makefile
