2017-12-26clk: use atomic runtime pm api in clk_core_is_enabledDong Aisheng1-1/+2
Current clk_pm_runtime_put is using pm_runtime_put_sync which is not safe to be called in clk_core_is_enabled as it should be able to run in atomic context. Thus use pm_runtime_put instead which is atomic safe.

2017-12-19clk: sunxi: sun9i-mmc: Implement reset callback for reset controlsChen-Yu Tsai1-0/+12
Our MMC host driver now issues a reset, instead of just deasserting the reset control, since commit c34eda69ad4c ("mmc: sunxi: Reset the device at probe time"). The sun9i-mmc clock driver does not support this, and will fail, which results in MMC not probing. This patch implements the reset callback by asserting the reset control, then deasserting it after a small delay.

2017-12-05clk: Manage proper runtime PM state in clk_change_rate()Marek Szyprowski1-0/+5
clk_change_rate() propagates rate change down to all its children. Such operation requires managing proper runtime PM state of each child, what was missing. Add needed calls to clk_pm_runtime*() to ensure that set_rate() clock callback is called on runtime active clock. This fixes following issue found on Exynos5433 TM2 board with devfreq enabled: Synchronous External Abort: synchronous external abort (0x96000210) at 0xffffff80093f5600 Internal error: : 96000210 [#1] PREEMPT SMP Modules linked in: CPU: 0 PID: 5 Comm: kworker/u16:0 Not tainted 4.15.0-rc1-next-20171129+ #4 Hardware name: Samsung TM2 board (DT) Workqueue: devfreq_wq devfreq_monitor task: ffffffc0ca96b600 task.stack: ffffff80093a8000 pstate: a0000085 (NzCv daIf -PAN -UAO) pc : clk_divider_set_rate+0x54/0x118 lr : clk_divider_set_rate+0x44/0x118 ...

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis. Summary: Core: - runtime PM support for clk providers - devm API for of_clk_add_hw_provider() New Drivers: - Mediatek MT2712 and MT7622 - Renesas R-Car V3M SoC Updates: - runtime PM support for Samsung exynos5433/exynos4412 providers - removal of clkdev aliases on Samsung SoCs - convert clk-gpio to use gpio descriptors - various driver cleanups to match kernel coding style - Amlogic Video Processing Unit VPU and VAPB clks - sigma-delta modulation for Allwinner audio PLLs - Allwinner A83t Display clks - support for the second display unit clock on Renesas RZ/G1E - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR - new clock ids for Rockchip rk3188 and rk3368 SoCs - various 'const' markings on clk_ops structures - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: stm32h7: fix test of clock config clk: pxa: fix building on older compilers clk: sunxi-ng: a83t: Fix i2c buses bits clk: ti: dra7-atl-clock: fix child-node lookups clk: qcom: common: fix legacy board-clock registration clk: uniphier: fix DAPLL2 clock rate of Pro5 clk: uniphier: fix parent of miodmac clock data clk: hi3798cv200: correct parent mux clock for 'clk_sdio0_ciu' clk: hisilicon: Delete an error message for a failed memory allocation in hisi_register_clkgate_sep() clk: hi3660: fix incorrect uart3 clock freqency clk: kona-setup: Delete error messages for failed memory allocations ARC: clk: fix spelling mistake: "configurarion" -> "configuration" clk: cdce925: remove redundant check for non-null parent_name clk: versatile: Improve sizeof() usage clk: versatile: Delete error messages for failed memory allocations clk: ux500: Improve sizeof() usage clk: ux500: Delete error messages for failed memory allocations clk: spear: Delete error messages for failed memory allocations clk: ti: Delete error messages for failed memory allocations clk: mmp: Adjust checks for NULL pointers ...

2017-11-13clk: mmp: Use common error handling code in mmp_clk_register_mix()Markus Elfring1-6/+8
Add a jump target so that a bit of exception handling can be better reused at the end of this function. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2017-11-03Update MIPS email addressesPaul Burton5-5/+5
MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.
