Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "Sort of on the quieter side this time, which is probably due more to me not catching up as quickly on patch review than anything else. Overall it seems normal though, a few small changes to the core, mostly small non-critical fixes here and there as well as driver updates for new and existing hardware support. The biggest things are the TI clk driver rework to lay the groundwork for clkctrl support in the next merge window and the AmLogic audio/graphics clk support. Core: - clk_possible_parents debugfs file so we know which parents a clk could possibly have - Fix to make clk rate change notifiers stop on the first failure instead of continuing New Drivers: - Mediatek MT6797 SoCs - hi655x PMIC clks - AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks - Allwinner H5 SoCs and PRCM hardware Updates: - Nvidia Tegra T210 cleanups and non-critical fixes - TI OMAP cleanups in preparation for clkctrl support - trivial fixes like kcalloc(), devm_* conversions, and seq_puts() - ZTE zx296718 SoC VGA clks - Rockchip clk-ids, fixups, and rename of rk1108 to rv1108 - IDT VersaClock 5P49V5935 support - Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (151 commits) clk: x86: pmc-atom: Checking for IS_ERR() instead of NULL clk: ti: divider: try to fix ti_clk_register_divider clk: mvebu: Use kcalloc() in two functions clk: mvebu: Use kcalloc() in of_cpu_clk_setup() clk: nomadik: Delete error messages for a failed memory allocation in two functions clk: nomadik: Use seq_puts() in nomadik_src_clk_show() clk: Improve a size determination in two functions clk: Replace four seq_printf() calls by seq_putc() clk: si5351: Delete an error message for a failed memory allocation in si5351_i2c_probe() clk: si5351: Use devm_kcalloc() in si5351_i2c_probe() clk: at91: Use kcalloc() in of_at91_clk_pll_get_characteristics() reset: mediatek: Add MT2701 ethsys reset controller include file clk: mediatek: add mt2701 ethernet reset clk: hi6220: Add the hi655x's pmic clock clk: ti: fix building without legacy omap3 clk: ti: fix linker error with !SOC_OMAP4 clk: hi3620: Fix a typo in one variable name clk: hi3620: Delete error messages for a failed memory allocation in two functions clk: hi3620: Use kcalloc() in hi3620_mmc_clk_init() clk: hisilicon: Delete error messages for failed memory allocations in hisi_clk_init() ...
