This patch adds support for human readable names defined in 'label' property. Such names are visible to userspace and makes debugging much easier.

2017-01-06soc: rockchip: add driver handling grf setupHeiko Stuebner
The General Register Files are an area of registers containing a lot of single-bit settings for numerous components as well full components like usbphy control. Therefore all used components are accessed via the syscon provided by the grf nodes or from the sub-devices created through the simple-mfd created from the grf node. Some settings are not used by anything but will need to be set up according to expectations on the kernel side. Best example is the force_jtag setting, which defaults to on and results in the soc switching the pin-outputs between jtag and sdmmc automatically depending on the card-detect status. This conflicts heavily with how the dw_mmc driver expects to do its work and also with the clock-controller, which has most likely deactivated the jtag clock due to it being unused. So far the handling of this setting was living in the mach-rockchip code for the arm32-based rk3288 but that of course doesn't work for arm64 socs and would also look ugly for further arm32 socs. Also always disabling this setting is quite specific to linux and its subsystems, other operating systems might prefer other settings, so that the bootloader cannot really set a sane default for all. So introduce a top-level driver for the grf that handles these settings that need to be a certain way but nobody cares about. Other needed settings might surface in the future and can then be added here, but only as a last option. Ideally general GRF settings should be handled in the driver needing them.

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" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (150 commits) clk: bcm: Fix 'maybe-uninitialized' warning in bcm2835_clock_choose_div_and_prate() clk: add devm_get_clk_from_child() API clk: st: clk-flexgen: Unmap region obtained by of_iomap clk: keystone: pll: Unmap region obtained by of_iomap clk:mmp:clk-of-mmp2: Free memory and Unmap region obtained by kzalloc and of_iomap clk:mmp:clk-of-pxa910: Free memory and Unmap region obtained by kzmalloc and of_iomap clk: mmp: clk-of-pxa1928: Free memory obtained by kzalloc clk: cdce925: Fix limit check clk: bcm: Make COMMON_CLK_IPROC into a library clk: qoriq: added ls1012a clock configuration clk: ti: dra7: fix "failed to lookup clock node gmac_gmii_ref_clk_div" boot message clk: bcm: Allow rate change propagation to PLLH_AUX on VEC clock clk: bcm: Support rate change propagation on bcm2835 clocks clk: bcm2835: Avoid overwriting the div info when disabling a pll_div clk clk: ti: omap36xx: Work around sprz319 advisory 2.1 clk: clk-wm831x: fix a logic error clk: uniphier: add cpufreq data for LD11, LD20 SoCs clk: uniphier: add CPU-gear change (cpufreq) support clk: qcom: Put venus core0/1 gdscs to hw control mode clk: qcom: gdsc: Add support for gdscs with HW control ...

2016-11-29soc: fsl: fix section mismatch build warningsSudeep Holla
We get the following warning with the driver is compiled in: WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported: WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the function fsl_guts_probe() to the function .init.text:of_flat_dt_get_machine_name() The function fsl_guts_probe() references the function __init of_flat_dt_get_machine_name(). This is often because fsl_guts_probe lacks a __init annotation or the annotation of of_flat_dt_get_machine_name is wrong. This patch fixes the issue by using the normal DT/OF API rather than the of_flat_* one.
