soc: Convert to using %pOFn instead of device_node.name

2018-10-04T19:16:01+00:00

In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier.

Pull clk updates from Stephen Boyd: "This time we have a good set of changes to the core framework that do some general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for Actions Semi so it takes up some lines to add all the different types, and the Qualcomm diff is there because we add support for two SoCs and it's quite a bit of data. Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And then the long tail of driver updates for various fixes and stuff follows after that. Core: - debugfs cleanups removing error checking and an unused provider API - Removal of a clk init typedef that isn't used - Usage of match_string() to simplify parent string name matching - OF clk helpers moved to their own file (linux/of_clk.h) - Make clk warnings more readable across kernel versions New Drivers: - Qualcomm SDM845 GCC and Video clk controllers - Qualcomm MSM8998 GCC - Actions Semi S900 SoC support - Nuvoton npcm750 microcontroller clks - Amlogic axg AO clock controller Removed Drivers: - Deprecated Rockchip clk-gate driver Updates: - debugfs functions stopped checking return values - Support for the MSIOF module clocks on Rensas R-Car M3-N - Support for the new Rensas RZ/G1C and R-Car E3 SoCs - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs - Berlin and Amlogic SPDX tagging - Usage of of_clk_get_parent_count() in more places - Proper implementation of the CDEV1/2 clocks on Tegra20 - Allwinner H6 PRCM clock support and R40 EMAC support - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet - Round closest support for meson's mpll driver - Support for meson8b nand clocks and gxbb video decoder clocks - Mediatek mali clks - STM32MP1 fixes - Uniphier LD11/LD20 stream demux system clock" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) clk: qcom: Export clk_fabia_pll_configure() clk: bcm: Update and add Stingray clock entries dt-bindings: clk: Update Stingray binding doc clk-si544: Properly round requested frequency to nearest match clk: ingenic: jz4770: Add 150us delay after enabling VPU clock clk: ingenic: jz4770: Enable power of AHB1 bus after ungating VPU clock clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle clk: ingenic: jz4770: Change OTG from custom to standard gated clock clk: ingenic: Support specifying "wait for clock stable" delay clk: ingenic: Add support for clocks whose gate bit is inverted clk: use match_string() helper clk: bcm2835: use match_string() helper clk: Return void from debug_init op clk: remove clk_debugfs_add_file() clk: tegra: no need to check return value of debugfs_create functions clk: davinci: no need to check return value of debugfs_create functions clk: bcm2835: no need to check return value of debugfs_create functions clk: no need to check return value of debugfs_create functions clk: imx6: add EPIT clock support clk: mvebu: use correct bit for 98DX3236 NAND ...

treewide: Use struct_size() for devm_kmalloc() and friends

Solve the pd could only ever turn off but never turn them on again, if the pd registers have the writemask bits. So far this affects the rk3328 only.

soc: rockchip: power-domain: Use of_clk_get_parent_count() instead of open coding

2018-05-02T15:33:52+00:00

As of_clk_get_parent_count() returns zero on failure, while of_count_phandle_with_args() might return a negative error code, this also fixes the issue of possibly using a negative number in the allocation below.
