2018-05-15clk: stm32: fix: stm32 clock drivers are not compiled by defaultGabriel Fernandez
Clock driver is mandatory if the machine is selected. Then don't use 'bool' and 'depends on' commands, but 'def_bool' with the machine(s).

2018-05-15clk: imx6ull: use OSC clock during AXI rate changeStefan Agner
On i.MX6 ULL using PLL3 seems to cause a freeze when setting the parent to IMX6UL_CLK_PLL3_USB_OTG. This only seems to appear since commit 6f9575e55632 ("clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux"), probably because the clock is now forced to be on.

2018-04-25clk: meson: meson8b: fix meson8b_cpu_clk parent clock nameMartin Blumenstingl
meson8b_cpu_clk has two parent clocks: - meson8b_xtal - meson8b_cpu_scale_out_sel The name of the "xtal" clock parent is specified correctly. However, there is a typo in the name of the second parent clock. The meson8b_cpu_scale_out_sel definition uses the name "cpu_scale_out_sel" (which matches the name from the datasheet). However, the mux parent definition uses the name "cpu_out_sel" which does not match any existing clock.

2018-04-25clk: meson: meson8b: fix meson8b_fclk_div3_div clock nameMartin Blumenstingl
The names of all fclk divider gate clocks follow the naming schema "fclk_divN" and the name of all fclk fixed dividers follow the naming schema "fclk_divN_div". There's one exception to this rule: meson8b_fclk_div3_div's name is "fclk_div_div3". It's child clock meson8b_fclk_div3 however references it as "fclk_div3_div" (following the naming schema explained above). Fix the naming of the meson8b_fclk_div3_div clock to follow the naming schema. This also fixes serial console on my Meson8m2 board because "clk81" uses fclk_div3 as parent. However, since the hierarchy stops at meson8b_fclk_div3 there's no known parent clock and the rate of "clk81" and all of it's children (UART clock, SDIO MMC controller clock, ...) are all 0.

2018-04-16clk: meson: honor CLK_MUX_ROUND_CLOSEST in clk_regmapJerome Brunet
Using __clk_mux_determine_rate effectively ignores CLK_MUX_ROUND_CLOSEST if set the related clk_regmap mux instance. Use clk_mux_determine_rate_flags() to make sure the flag is honored.

2018-04-16clk: honor CLK_MUX_ROUND_CLOSEST in generic clk muxJerome Brunet
CLK_MUX_ROUND_CLOSEST is part of the clk_mux documentation but clk_mux directly calls __clk_mux_determine_rate(), which overrides the flag. As result, if clk_mux is instantiated with CLK_MUX_ROUND_CLOSEST, the flag will be ignored and the clock rounded down. To solve this, this patch expose clk_mux_determine_rate_flags() in the clk-provider API and uses it in the determine_rate() callback of clk_mux.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The large diff this time around is from the addition of a new clk driver for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well. Core: - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops - debugfs ops macroized to shave some lines of boilerplate code - Always calculate the phase instead of caching it in clk_get_phase() - More __must_check on bulk clk APIs New Drivers: - TI's Davinci family of SoCs - Intel's Stratix10 SoC - stm32mp157 SoC - Allwinner H6 CCU - Silicon Labs SI544 clock generator chip - Renesas R-Car M3-N and V3H SoCs - i.MX6SLL SoCs Removed Drivers: - ST-Ericsson AB8540/9540 Updates: - Mediatek MT2701 and MT7622 audsys support and MT2712 updates - STM32F469 DSI and STM32F769 sdmmc2 support - GPIO clks can sleep now - Spreadtrum SC9860 RTC clks - Nvidia Tegra MBIST workarounds and various minor fixes - Rockchip phase handling fixes and a memory leak plugged - Renesas drivers switch to readl/writel from clk_readl/clk_writel - Renesas gained CPU (Z/Z2) and watchdog support - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support - Qualcomm PM8921 PMIC XO buffers - Amlogic migrates to regmap APIs - TI Keystone clk latching support - Allwinner H3 and H5 video clk fixes - Broadcom BCM2835 PLLs needed another bit to enable - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix - i.MX6UL/ULL epdc_podf support - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (233 commits) clk: davinci: add a reset lookup table for psc0 clk: imx: add clock driver for imx6sll dt-bindings: imx: update clock doc for imx6sll clk: imx: add new gate/gate2 wrapper funtion clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux clk: cs2000: set pm_ops in hibernate-compatible way clk: bcm2835: De-assert/assert PLL reset signal when appropriate clk: imx7d: Move clks_init_on before any clock operations clk: imx7d: Correct ahb clk parent select clk: imx7d: Correct dram pll type clk: imx7d: Add USB clock information clk: socfpga: stratix10: add clock driver for Stratix10 platform dt-bindings: documentation: add clock bindings information for Stratix10 clk: ti: fix flag space conflict with clkctrl clocks clk: uniphier: add additional ethernet clock lines for Pro4 clk: uniphier: add SATA clock control support clk: uniphier: add PCIe clock control support clk: Add driver for the si544 clock generator chip clk: davinci: Remove redundant dev_err calls clk: uniphier: add ethernet clock control support for PXs3 ...

2018-04-05clk: ti: fix flag space conflict with clkctrl clocksTero Kristo
The introduction of support for CLK_SET_RATE_PARENT flag for clkctrl clocks used a generic clock flag, which causes a conflict with the rest of the clkctrl flags, namely the NO_IDLEST flag. This can cause boot failures on certain platforms where this flag is introduced, by omitting the wait for the clockctrl module to be fully enabled before proceeding with rest of the code. Fix this by moving all the clkctrl specific flags to their own bit-range.

Since hclk_sd and pclk_ddr source clock from CPLL or GPLL, and these two PLL may change their frequency. If we do not assign right id to pclk_ddr and hclk_sd, they will alway use default cur register value, and may get the frequency exceed their signed off frequency. So assign correct Id for them, then we can assign frequency for them in dts.

The newly added clock notifier may return an error code but so far the error output in the function would only return an error pointer from registering the clock. So when the clock notifier fails the clock would be unregistered but the return would still be the clock pointer which could then not be dereferenced correctly. So fix the error handling to prevent that.
