Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "The diff is dominated by the Allwinner A10/A20 SoCs getting converted to the sunxi-ng framework. Otherwise, the heavy hitters are various drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are some other new clk drivers in here too but overall this is just a bunch of clk drivers for various different pieces of hardware and a collection of non-critical fixes for clk drivers. New Drivers: - Allwinner R40 SoCs - Renesas R-Car Gen3 USB 2.0 clock selector PHY - Atmel AT91 audio PLL - Uniphier PXs3 SoCs - ARC HSDK Board PLLs - AXS10X Board PLLs - STMicroelectronics STM32H743 SoCs Removed Drivers: - Non-compiling mb86s7x support Updates: - Allwinner A10/A20 SoCs converted to sunxi-ng framework - Allwinner H3 CPU clk fixes - Renesas R-Car D3 SoC - Renesas V2H and M3-W modules - Samsung Exynos5420/5422/5800 audio fixes - Rockchip fractional clk approximation fixes - Rockchip rk3126 SoC support within the rk3128 driver - Amlogic gxbb CEC32 and sd_emmc clks - Amlogic meson8b reset controller support - IDT VersaClock 5P49V5925/5P49V6901 support - Qualcomm MSM8996 SMMU clks - Various 'const' applications for struct clk_ops - si5351 PLL reset bugfix - Uniphier audio on LD11/LD20 and ethernet support on LD11/LD20/Pro4/PXs2 - Assorted Tegra clk driver fixes" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (120 commits) clk: si5351: fix PLL reset ASoC: atmel-classd: remove aclk clock ASoC: atmel-classd: remove aclk clock from DT binding clk: at91: clk-generated: make gclk determine audio_pll rate clk: at91: clk-generated: create function to find best_diff clk: at91: add audio pll clock drivers dt-bindings: clk: at91: add audio plls to the compatible list clk: at91: clk-generated: remove useless divisor loop clk: mb86s7x: Drop non-building driver clk: ti: check for null return in strrchr to avoid null dereferencing clk: Don't write error code into divider register clk: uniphier: add video input subsystem clock clk: uniphier: add audio system clock clk: stm32h7: Add stm32h743 clock driver clk: gate: expose clk_gate_ops::is_enabled clk: nxp: clk-lpc32xx: rename clk_gate_is_enabled() clk: uniphier: add PXs3 clock data clk: hi6220: change watchdog clock source clk: Kconfig: Name RK805 in Kconfig for COMMON_CLK_RK808 clk: cs2000: Add cs2000_set_saved_rate ...

+* Renesas R-Car USB 2.0 clock selector
+
+This file provides information on what the device node for the R-Car USB 2.0
+clock selector.
+
+If you connect an external clock to the USB_EXTAL pin only, you should set
+the clock rate to "usb_extal" node only.
+If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
+is not needed because this is default setting. (Of course, you can set the
+clock rates to both "usb_extal" and "usb_xtal" nodes.
+
+Case 1: An external clock connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |External |---|USB_EXTAL ---> all usb channels|
+ |clock | |USB_XTAL |
+ +----------+ +-------------------------------+
+In this case, we need this driver with "usb_extal" clock.
+
+Case 2: An oscillator connects to R-Car SoC
+ +----------+ +--- R-Car ---------------------+
+ |Oscillator|---|USB_EXTAL -+-> all usb channels|
+ | |---|USB_XTAL --+ |
+ +----------+ +-------------------------------+
+In this case, we don't need this selector.
+
+Required properties:
+- compatible: "renesas,r8a7795-rcar-usb2-clock-sel" if the device is a part of
+ an R8A7795 SoC.
+ "renesas,r8a7796-rcar-usb2-clock-sel" if the device if a part of
+ an R8A7796 SoC.
+ "renesas,rcar-gen3-usb2-clock-sel" for a generic R-Car Gen3
+ compatible device.
+
+ When compatible with the generic version, nodes must list the
+ SoC-specific version corresponding to the platform first
+ followed by the generic version.
+
+- reg: offset and length of the USB 2.0 clock selector register block.
+- clocks: A list of phandles and specifier pairs.
+- clock-names: Name of the clocks.
+ - The functional clock must be "ehci_ohci"
+ - The USB_EXTAL clock pin must be "usb_extal"
+ - The USB_XTAL clock pin must be "usb_xtal"
+- #clock-cells: Must be 0
+
+Example (R-Car H3):
+
+ usb2_clksel: clock-controller@e6590630 {

+STMicroelectronics STM32H7 Reset and Clock Controller
+=====================================================
+
+The RCC IP is both a reset and a clock controller.
+
+Please refer to clock-bindings.txt for common clock controller binding usage.
+Please also refer to reset.txt for common reset controller binding usage.
+
+Required properties:
+- compatible: Should be:
+ "st,stm32h743-rcc"
+
+- reg: should be register base and length as documented in the
+ datasheet
+
+- #reset-cells: 1, see below
+
+- #clock-cells : from common clock binding; shall be set to 1
+
+- clocks: External oscillator clock phandle
+ - high speed external clock signal (HSE)
+ - low speed external clock signal (LSE)
+ - external I2S clock (I2S_CKIN)
+
+Optional properties:
+- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
+ write protection (RTC clock).
+
+Example:
+
+ rcc: reset-clock-controller@58024400 {
+ compatible = "st,stm32h743-rcc", "st,stm32-rcc";
+ reg = <0x58024400 0x400>;
+ #reset-cells = <1>;
+ #clock-cells = <2>;
+ clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
+
+ st,syscfg = <&pwrcfg>;
+};
+
+The peripheral clock consumer should specify the desired clock by
+having the clock ID in its "clocks" phandle cell.
+
+Example:
+
+ timer5: timer@40000c00 {
+ compatible = "st,stm32-timer";
+ reg = <0x40000c00 0x400>;
+ interrupts = <50>;
+ clocks = <&rcc TIM5_CK>;
+ };
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+
+For example, for CRC reset:
+ crc = AHB4RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x88 / 4 * 32 + 19 = 1107
+
+Example:
+
+ timer2 {
+ resets = <&rcc STM32H7_APB1L_RESET(TIM2)>;
+ };
