2018-12-25Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linuxLinus Torvalds5-562/+96
Pull clk updates from Stephen Boyd: "This round is dominated by NXP's i.MX clk drivers. We gained support for two or three i.MX SoCs in here and that mostly means a lot of driver code and data. Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk drivers added in here, and then we get to the long tail of driver updates and non-critical fixes all around, including code for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal. Apart from the usual driver updates we have an update to make registering OF based clk providers a little simpler when they're devices created as a child of a device backed by a node in DT. Drivers don't have to jump through hoops to unregister the provider upon driver removal anymore because the API does the right thing and uses the parent device DT node. Summary: Core: - Make devm_of_clk_add_hw_provider() use parent dt node if necessary - Various SPDX taggings - Mark clk_ops const when possible New Drivers: - NXP i.MX7ULP SoC clock support - NXP i.MX8QXP SoC clock support - NXP i.MX8MQ SoC clock support - NXP QorIQ T1023 SoC support - Qualcomm SDM845 audio subsystem clks - Qualcomm SDM845 GPU clck controllers - Qualcomm QCS404 RPM clk support - Mediatek MT7629 SoC clk controllers - Allwinner F1c100s SoC clocks - Allwinner H6 display engine clocks - Amlogic GX video clocks - Support for Amlogic meson8b CPU frequency scaling - Amlogic Meson8b CPU post-divider clocks Updates: - Proper suspend/resume on VersaClock5 - Shrink code some with DEFINE_SHOW_ATTRIBUTE() - Register fixes for Rockchip rk3188 and rk3328 - One new critical clock for Rockchip rk3188 and a fixed clock id (double used number) - New clock id for Rockchip rk3328 - Amlogic Meson8/Meson8b video clock support - Amlogic got a clk-input helper and used it for the axg-audio clock driver - Sigma Delta modulation for the Allwinner A33 audio clocks - Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs - Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W - Support for SDHI and USB clocks on Renesas RZ/A2 - Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M - Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks, etc)" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (172 commits) clk: imx: imx7ulp: add arm hsrun mode clocks support dt-bindings: clock: imx7ulp: add HSRUN mode related clocks clk: Use of_node_name_eq for node name comparisons clk: vc5: Add suspend/resume support clk: qcom: Drop unused 8998 clock clk: qcom: Leave mmss noc on for 8998 clk: tegra: Return the exact clock rate from clk_round_rate clk: tegra30: Use Tegra CPU powergate helper function soc/tegra: pmc: Drop SMP dependency from CPU APIs clk: tegra: Fix maximum audio sync clock for Tegra124/210 clk: tegra: get rid of duplicate defines clk: imx: add imx8qxp lpcg driver clk: imx: add lpcg clock support clk: imx: add imx8qxp clk driver clk: imx: Make the i.MX8MQ CCM clock driver CLK_IMX8MQ dependant clk: imx: add scu clock common part clk: imx: add configuration option for mmio clks dt-bindings: clock: add imx8qxp lpcg clock binding dt-bindings: clock: imx8qxp: add SCU clock IDs clk: qcom: Add missing msm8998 resets ...

2018-12-19regmap: irq: add an option to clear status registers on unmaskBartosz Golaszewski1-0/+4
Some interrupt controllers whose interrupts are acked on read will set the status bits for masked interrupts without changing the state of the IRQ line. Some chips have an additional "feature" where if those set bits are not cleared before unmasking their respective interrupts, the IRQ line will change the state and we'll interpret this as an interrupt although it actually fired when it was masked. Add a new field to the irq chip struct that tells the regmap irq chip code to always clear the status registers before actually changing the irq mask values.

Add level active IRQ support to regmap-irq irqchip. Change breaks existing regmap-irq type setting. Convert the existing drivers which use regmap-irq with trigger type setting (gpio-max77620) to work with this new approach. So we do not magically support level-active IRQs on gpio-max77620 - but add support to the regmap-irq for chips which support them =) We do not support distinguishing situation where HW supports rising and falling edge detection but not both. Separating this would require inventing yet another flags for IRQ types. Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2018-12-19PM-runtime: Switch autosuspend over to using hrtimersVincent Guittot2-5/+6
PM-runtime uses the timer infrastructure for autosuspend. This implies that the minimum time before autosuspending a device is in the range of 1 tick included to 2 ticks excluded -On arm64 this means between 4ms and 8ms with default jiffies configuration -And on arm, it is between 10ms and 20ms These values are quite high for embedded systems which sometimes want the duration to be in the range of 1 ms. It is possible to switch autosuspend over to using hrtimers to get finer granularity for short durations and take advantage of slack to retain some margins and get long timeouts with minimum wakeups. On an arm64 platform that uses 1ms for autosuspending timeout of its GPU, idle power is reduced by 10% with hrtimer. The latency impact on arm64 hikey octo cores is: - mark_last_busy: from 1.11 us to 1.25 us - rpm_suspend: from 15.54 us to 15.38 us [Only the code path of rpm_suspend() that starts hrtimer has been measured.] arm64 image (arm64 default defconfig) decreases by around 3KB with following details: $ size vmlinux-timer text data bss dec hex filename 12034646 6869268 386840 19290754 1265a82 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 12030550 6870164 387032 19287746 1264ec2 vmlinux The latency impact on arm 32bits snowball dual cores is : - mark_last_busy: from 0.31 us usec to 0.77 us - rpm_suspend: from 6.83 us to 6.67 usec The increase of the image for snowball platform that I used for testing performance impact, is neglictable (244B). $ size vmlinux-timer text data bss dec hex filename 7157961 2119580 264120 9541661 91981d build-ux500/vmlinux size vmlinux-hrtimer text data bss dec hex filename 7157773 2119884 264248 9541905 919911 vmlinux-hrtimer And arm 32bits image (multi_v7_defconfig) increases by around 1.7KB with following details: $ size vmlinux-timer text data bss dec hex filename 13304443 6803420 402768 20510631 138f7a7 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 13304299 6805276 402768 20512343 138fe57 vmlinux Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Rafael J.

This has pulled in a few architecture changes as well. - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl. - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S controllers.

2018-12-14mm/sparse: add common helper to mark all memblocks presentLogan Gunthorpe1-0/+6
Presently the arches arm64, arm and sh have a function which loops through each memblock and calls memory present. riscv will require a similar function. Introduce a common memblocks_present() function that can be used by all the arches. Subsequent patches will cleanup the arches that make use of this.

2018-12-14mm: introduce common STRUCT_PAGE_MAX_SHIFT defineLogan Gunthorpe1-0/+5
This define is used by arm64 to calculate the size of the vmemmap region. It is defined as the log2 of the upper bound on the size of a struct page. We move it into mm_types.h so it can be defined properly instead of set and checked with a build bug. This also allows us to use the same define for riscv.

2018-12-14include/linux/compiler_types.h: don't pollute userspace with macro definitionsXiaozhou Liu1-54/+54
Macros 'inline' and '__gnu_inline' used to be defined in compiler-gcc.h, which was (and is) included entirely in (__KERNEL__ && !__ASSEMBLY__). Commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h mutually exclusive") had those macros exposed to userspace, unintentionally. Then commit a3f8a30f3f00 ("Compiler Attributes: use feature checks instead of version checks") moved '__gnu_inline' back into (__KERNEL__ && !__ASSEMBLY__) and 'inline' was left behind. Since 'inline' depends on '__gnu_inline', compiling error showing "unknown type name ‘__gnu_inline’" will pop up, if userspace somehow includes <linux/compiler.h>. Other macros like __must_check, notrace, etc. are in a similar situation. So just move all these macros back into (__KERNEL__ && !__ASSEMBLY__). Note: 1. This patch only affects what userspace sees. 2. __must_check (when !CONFIG_ENABLE_MUST_CHECK) and noinline_for_stack were once defined in __KERNEL__ only, but we believe that they can be put into !__ASSEMBLY__ too.

2018-12-14PM / Domains: Propagate performance state updatesViresh Kumar1-0/+4
Currently a genpd only handles the performance state requirements from the devices under its control. This commit extends that to also handle the performance state requirement(s) put on the master genpd by its sub-domains. There is a separate value required for each master that the genpd has and so a new field is added to the struct gpd_link (link->performance_state), which represents the link between a genpd and its master. The struct gpd_link also got another field prev_performance_state, which is used by genpd core as a temporary variable during transitions. On a call to dev_pm_genpd_set_performance_state(), the genpd core first updates the performance state of the masters of the device's genpd and then updates the performance state of the genpd. The masters do the same and propagate performance state updates to their masters before updating their own. The performance state transition from genpd to its master is done with the help of dev_pm_opp_xlate_performance_state(), which looks at the OPP tables of both the domains to translate the state.

2018-12-14PM / Domains: Save OPP table pointer in genpdViresh Kumar1-0/+2
dev_pm_genpd_set_performance_state() will be required to call dev_pm_opp_xlate_performance_state() going forward to translate from performance state of a sub-domain to performance state of its master. And dev_pm_opp_xlate_performance_state() needs pointers to the OPP tables of both genpd and its master. Lets fetch and save them while the OPP tables are added. Fetching the OPP tables should never fail as we just added the OPP tables and so add a WARN_ON() for such a bug instead of full error paths.

2018-12-14OPP: Don't return 0 on error from of_get_required_opp_performance_state()Viresh Kumar1-3/+3
of_get_required_opp_performance_state() returns 0 on errors currently and a positive performance state otherwise. Since 0 is a valid performance state (representing off), it would be better if this routine returns negative values on error. That will also make it behave similar to dev_pm_opp_xlate_performance_state(), which also returns performance states and returns negative values on error. Change the return type of the function to "int" in order to return negative values. This doesn't have any users for now and so no other part of the kernel will be impacted with this change.

2018-12-14OPP: Add dev_pm_opp_xlate_performance_state() helperViresh Kumar1-0/+7
dev_pm_genpd_set_performance_state() needs to handle performance state propagation going forward. Currently this routine only gets the required performance state of the device's genpd as an argument, but it doesn't know how to translate that to master genpd(s) of the device's genpd. Introduce a new helper dev_pm_opp_xlate_performance_state() which will be used to translate from performance state of a device (or genpd sub-domain) to another device (or master genpd). Normally the src_table (of genpd sub-domain) will have the "required_opps" property set to point to one of the OPPs in the dst_table (of master genpd), but in some cases the genpd and its master have one to one mapping of performance states and so none of them have the "required-opps" property set. Return the performance state of the src_table as it is in such cases.
