Commit b8d2798f authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This is a fairly quiet release. We don't have any patches to the core
  framework. The only patch that can even be considered "core" adds
  another clk_get() variant. The rest of the changes are in drivers for
  various SoCs, and we have a few bits for ARM shmobile architecture
  code (dts and mach) due to the dependency we're breaking between
  shmobile architecture code and its clk driver. Those shmobile bits
  have also been pulled into arm-soc tree. Here's the summary:

  Core:

   - Support for devm_get_clk_from_child() used with DT bindings that
     have subnodes with the 'clocks' property

  New Drivers:

   - Allwinner A64 (sun50i)
   - i.MX imx6ull
   - Socionext's UniPhier SoC CPUs
   - Mediatek MT2701 SoCs
   - Rockchip rk1108 SoCs
   - Qualcomm MSM8994/MSM8992 SoCS
   - Qualcomm RPM Clocks
   - Hisilicon Hi3516CV300 and Hi3798CV200 CRG
   - Oxford Semiconductor OX820 and OX810SE SoCs
   - Renesas RZ/G1M and RZ/GIE SoCs
   - Renesas R-Car RST driver for mode pin states

  Updates:

   - Four Allwinner SoCs are migrated to the new style clk driver
   - Rockchip rk3399,rk3066 PLL optimizations
   - i.MX LVDS display glitch fixes and AV PLL precision improvements
   - Qualcomm MSM8996 GPU GDSCs, hw controlled GDSCs, and Alpha PLL
     support
   - Explicit demodularization of always builtin drivers
   - Freescale Qoriq ls1012a and ls1046a support
   - Exynos 5433 parent typo fix and critical clock tagging
   - Renesas r8a7743/r8a7745 CPG
   - Renesas R-Car M3-W CSI2/VIN/SYS-DMAC/(H)SCIF/I2C/DRIF/gfx support
   - stm32f4* LSI, LSE, RTC, and QSPI clocks
   - pxa27x and pxa25x cpufreq as clks
   - TI omap36xx sprz319 advisory 2.1 workaround
   - Broadcom bcm2835 rate change propogation to PLLH_AUX from VEC"

Qualcomm RPM Clock Controller Binding
------------------------------------------------
The RPM is a dedicated hardware engine for managing the shared
SoC resources in order to keep the lowest power profile. It
communicates with other hardware subsystems via shared memory
and accepts clock requests, aggregates the requests and turns
the clocks on/off or scales them on demand.

* Rockchip RK1108 Clock and Reset Unit
The RK1108 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
Required Properties:
- compatible: should be "rockchip,rk1108-cru"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- #reset-cells: should be 1.
Optional Properties:
- rockchip,grf: phandle to the syscon managing the "general register files"
If missing pll rates are not changeable, due to the missing pll lock status.
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. All available clocks are defined as
preprocessor macros in the dt-bindings/clock/rk1108-cru.h headers and can be
used in device tree sources. Similar macros exist for the reset sources in
these files.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xin24m" - crystal input - required,
- "ext_vip" - external VIP clock - optional
- "ext_i2s" - external I2S clock - optional
- "ext_gmac" - external GMAC clock - optional
- "hdmiphy" - external clock input derived from HDMI PHY - optional
- "usbphy" - external clock input derived from USB PHY - optional
Example: Clock controller node:
cru: cru@20200000 {

rockchip,grf = <&grf>;
