2016-05-21Merge tag 'clk-for-linus' of ↵Linus Torvalds1-0/+1
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "It's the usual big pile of driver updates and additions, but we do have a couple core changes in here as well. Core: - CLK_IS_CRITICAL support has been added. This should allow drivers to properly express that a certain clk should stay on even if their prepare/enable count drops to 0 (and in turn the parents of these clks should stay enabled). - A clk registration API has been added, clk_hw_register(), and an OF clk provider API has been added, of_clk_add_hw_provider(). These APIs have been put in place to further split clk providers from clk consumers, with the goal being to have clk providers never deal with struct clk pointers at all. Conversion of provider drivers is on going. clkdev has also gained support for registering clk_hw pointers directly so we can convert drivers that don't use devicetree. New Drivers: - Marvell ap806 and cp110 system controllers (with clks inside!) - Hisilicon Hi3519 clock and reset controller - Axis ARTPEC-6 clock controllers - Oxford Semiconductor OXNAS clock controllers - AXS10X I2S PLL - Rockchip RK3399 clock and reset controller Updates: - MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos 542x SoCs, and some more clk ID exporting for bus frequency scaling - Proper BCM2835 PCM clk support and various other clks - i.MX clk updates for i.MX6SX, i.MX7, and VF610 - Renesas updates for R-Car H3 - Tegra210 got updates for DisplayPort and HDMI 2.0 - Rockchip driver refactorings and fixes due to adding RK3399 support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (139 commits) clk: fix critical clock locking clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPM clk: ingenic: Allow divider value to be divided clk: sunxi: Add display and TCON0 clocks driver clk: rockchip: drop old_rate calculation on pll rate changes clk: rockchip: simplify GRF handling in pll clocks clk: rockchip: lookup General Register Files in rockchip_clk_init clk: rockchip: fix the rk3399 sdmmc sample / drv name clk: mvebu: new driver for Armada CP110 system controller dt-bindings: arm: add DT binding for Marvell CP110 system controller clk: mvebu: new driver for Armada AP806 system controller clk: hisilicon: add CRG driver for hi3519 soc clk: hisilicon: export some hisilicon APIs to modules reset: hisilicon: add reset controller driver for hisilicon SOCs clk: bcm/kona: Do not use sizeof on pointer type clk: qcom: msm8916: Fix crypto clock flags clk: nxp: lpc18xx: Initialize clk_init_data::flags to 0 clk/axs10x: Add I2S PLL clock driver clk: imx7d: fix ahb clock mux 1 clk: fix comment of devm_clk_hw_register() ...

2016-04-20clk: Add {devm_}clk_hw_{register,unregister}() APIsStephen Boyd1-0/+1
We've largely split the clk consumer and provider APIs along struct clk and struct clk_hw, but clk_register() still returns a struct clk pointer for each struct clk_hw that's registered. Eventually we'd like to only allocate struct clks when there's a user, because struct clk is per-user now, so clk_register() needs to change. Let's add new APIs to register struct clk_hws, but this time we'll hide the struct clk from the caller by returning an int error code. Also add an unregistration API that takes the clk_hw structure that was passed to the registration API. This way provider drivers never have to deal with a struct clk pointer unless they're using the clk consumer APIs. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

Introduce gpiod_get_optional() and gpiod_get_index_optional() helpers that make it easier for drivers to handle optional GPIOs. Currently in order to handle optional GPIOs, a driver needs to special case error handling for -ENOENT, such as this: gpio = gpiod_get(dev, "foo"); if (IS_ERR(gpio)) { if (PTR_ERR(gpio) != -ENOENT) return PTR_ERR(gpio); gpio = NULL; } if (gpio) { /* set up GPIO */ } With these new helpers the above is reduced to: gpio = gpiod_get_optional(dev, "foo"); if (IS_ERR(gpio)) return PTR_ERR(gpio); if (gpio) { /* set up GPIO */ } While at it, device-managed variants of these functions are also provided.

This mostly consists of patches that didn't quite make the last cycle. Lots of interesting things under review currently. Core: - Add devm_iio_device_register/unregister. I took some convincing on whether there would be many devices that really were simple enough to need no explicit actions on removal. Turns out there are some. - Move some stray docs to above the relevant implemenation. - Drop a redundant repeated check on the fact the trigger has actually changed when there is a userspace attempt change it. Drivers: New drivers - Freescale MPL3115A2 Pressure / temperature sensor New functionality - hid_sensors: add sensitivity support. DT bindings - tsl2563 - hmc5843 Cleanups - Drop unused scan_type from viperboard adc driver. - devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130, adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018 and ad2s1200. Note that this was proposed in a number of other drivers and this revealed a number of missorderings in remove functions. Also for now I have blocked this on any device that any hardware suspend suport on the basis that we probably want to power down devices if they have no driver support loaded.

2013-01-22lib: devres: Introduce devm_ioremap_resource()Thierry Reding1-1/+2
The devm_request_and_ioremap() function is very useful and helps avoid a whole lot of boilerplate. However, one issue that keeps popping up is its lack of a specific error code to determine which of the steps that it performs failed. Furthermore, while the function gives an example and suggests what error code to return on failure, a wide variety of error codes are used throughout the tree. In an attempt to fix these problems, this patch adds a new function that drivers can transition to. The devm_ioremap_resource() returns a pointer to the remapped I/O memory on success or an ERR_PTR() encoded error code on failure. Callers can check for failure using IS_ERR() and determine its cause by extracting the error code using PTR_ERR(). devm_request_and_ioremap() is implemented as a wrapper around the new API and return NULL on failure as before. This ensures that backwards compatibility is maintained until all users have been converted to the new API, at which point the old devm_request_and_ioremap() function should be removed. A semantic patch is included which can be used to convert from the old devm_request_and_ioremap() API to the new devm_ioremap_resource() API. Some non-trivial cases may require manual intervention, though.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control subsystem changes from Linus Walleij: - Generic Device Tree bindings and hooks for drivers so we can move over modern drivers to using this. - Device Tree bindings for Tegra SoCs. - Funneling some devicetree helper code for the drivers/of subsystem. - New pin control drivers for: * Freescale MXS * Freescale i.MX51 * Freescale i.MX53 All of these use Device Tree bindings. - Dummy pinctrl handles for stepwise migration to pinctrl, akin to dummy regulators. - Minor non-urgent fixes and improvments. Fix up trivial conflicts in Documentation/driver-model/devres.txt and drivers/pinctrl/core.c, * tag 'pinctrl-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (46 commits) pinctrl: pinctrl-imx: add imx51 pinctrl driver pinctrl: pinctrl-imx: add imx53 pinctrl driver pinctrl: pinctrl-pxa3xx: remove empty pinmux disable function pinctrl: pinctrl-mxs: remove empty pinmux disable function pinctrl: pinctrl-imx: remove empty pinmux disable function pinctrl: make pinmux disable function optional pinctrl: a minor error checking improvement for pinconf pinctrl: mxs: skip gpio nodes for group creation pinctrl: mxs: create group for pin config node pinctrl: (cosmetic) fix two entries in DocBook comments pinctrl: add more info to error msgs in pin_request pinctrl: add pinctrl-mxs support pinctrl: pinctrl-imx: add imx6q pinctrl driver pinctrl: pinctrl-imx: add imx pinctrl core driver dt: add of_get_child_count helper function pinctrl: support gpio request deferred probing pinctrl: add pinctrl_provide_dummies interface for platforms to use pinctrl: enhance reporting of errors when loading from DT pinctrl: add kerneldoc for pinctrl_ops device tree functions pinctrl: propagate map validation errors ...
