2022-03-11clk: hisilicon: Terminate clk_div_table with sentinel elementJonathan Neuschäfer
In order that the end of a clk_div_table can be detected, it must be terminated with a sentinel element (.div = 0).

This driver is a platform driver. The probe function can be called after kernel init, and try to reference kernel memory that has been freed. Drop the __init markings everywhere here to avoid referencing initdata from non-init code. Fixes modpost warnings.

There is a potential execution path in which function platform_get_resource() returns NULL. If this happens, we will end up having a NULL pointer dereference. Fix this by replacing devm_ioremap with devm_ioremap_resource, which has the NULL check and the memory region request. This code was detected with the help of Coccinelle.

2018-06-01clk/driver/hisi: Consolidate the Kconfig for the CLOCK_STUBDaniel Lezcano
The current defconfig is inconsistent as it selects the mailbox and the clock for the hi6220 and the hi3660 without having their Kconfigs making sure the dependencies are correct. It ends up when selecting different versions for the kernel (for example when git bisecting) those options disappear and they don't get back, leading to unexpected behaviors. In our case, the cpufreq driver does no longer work because the clock fails to initialize due to the clock stub and the mailbox missing. In order to have the dependencies correctly set when defaulting, let's do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk automatically") where we select automatically the driver when the parent driver is selected. With sensible defaults in place, we can leave other choices for EXPERT.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The large diff this time around is from the addition of a new clk driver for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well. Core: - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops - debugfs ops macroized to shave some lines of boilerplate code - Always calculate the phase instead of caching it in clk_get_phase() - More __must_check on bulk clk APIs New Drivers: - TI's Davinci family of SoCs - Intel's Stratix10 SoC - stm32mp157 SoC - Allwinner H6 CCU - Silicon Labs SI544 clock generator chip - Renesas R-Car M3-N and V3H SoCs - i.MX6SLL SoCs Removed Drivers: - ST-Ericsson AB8540/9540 Updates: - Mediatek MT2701 and MT7622 audsys support and MT2712 updates - STM32F469 DSI and STM32F769 sdmmc2 support - GPIO clks can sleep now - Spreadtrum SC9860 RTC clks - Nvidia Tegra MBIST workarounds and various minor fixes - Rockchip phase handling fixes and a memory leak plugged - Renesas drivers switch to readl/writel from clk_readl/clk_writel - Renesas gained CPU (Z/Z2) and watchdog support - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support - Qualcomm PM8921 PMIC XO buffers - Amlogic migrates to regmap APIs - TI Keystone clk latching support - Allwinner H3 and H5 video clk fixes - Broadcom BCM2835 PLLs needed another bit to enable - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix - i.MX6UL/ULL epdc_podf support - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (233 commits) clk: davinci: add a reset lookup table for psc0 clk: imx: add clock driver for imx6sll dt-bindings: imx: update clock doc for imx6sll clk: imx: add new gate/gate2 wrapper funtion clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux clk: cs2000: set pm_ops in hibernate-compatible way clk: bcm2835: De-assert/assert PLL reset signal when appropriate clk: imx7d: Move clks_init_on before any clock operations clk: imx7d: Correct ahb clk parent select clk: imx7d: Correct dram pll type clk: imx7d: Add USB clock information clk: socfpga: stratix10: add clock driver for Stratix10 platform dt-bindings: documentation: add clock bindings information for Stratix10 clk: ti: fix flag space conflict with clkctrl clocks clk: uniphier: add additional ethernet clock lines for Pro4 clk: uniphier: add SATA clock control support clk: uniphier: add PCIe clock control support clk: Add driver for the si544 clock generator chip clk: davinci: Remove redundant dev_err calls clk: uniphier: add ethernet clock control support for PXs3 ...

The clock COMBPHY1 has already been supported by hi3798cv200 driver, but COMBPHY0 is missing. It adds COMBPHY0 clock support. Since the mux table is being shared by COMBPHY0 and COMBPHY1, it renames comphy1_mux_p and comphy1_mux_table a bit to drop instance number '1' from there.

2017-12-28clk: divider: fix incorrect usage of container_ofJerome Brunet
divider_recalc_rate() is an helper function used by clock divider of different types, so the structure containing the 'hw' pointer is not always a 'struct clk_divider' At the following line: > div = _get_div(table, val, flags, divider->width); in several cases, the value of 'divider->width' is garbage as the actual structure behind this memory is not a 'struct clk_divider' Fortunately, this width value is used by _get_val() only when CLK_DIVIDER_MAX_AT_ZERO flag is set. This has never been the case so far when the structure is not a 'struct clk_divider'. This is probably why we did not notice this bug before Fixes: afe76c8fd030 ("clk: allow a clk divider with max divisor when zero") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Acked-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-06clk: hisilicon: Add support for Hi3660 stub clocksKaihua Zhong
Hi3660 has four stub clocks, which are big and LITTLE cluster clocks, GPU clock and DDR clock. These clocks ask MCU for frequency scaling by sending message through mailbox. This commit adds support for stub clocks, it requests the dedicated mailbox channel at initialization; then later uses this channel to send message to MCU to execute frequency scaling. The four stub clocks share the same mailbox channel, but every stub clock has its own command id so MCU can distinguish the requirement coming for which clock. A shared memory is used to present effective frequency value, so the clock driver uses I/O mapping for the memory and reads back rate value.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis. Summary: Core: - runtime PM support for clk providers - devm API for of_clk_add_hw_provider() New Drivers: - Mediatek MT2712 and MT7622 - Renesas R-Car V3M SoC Updates: - runtime PM support for Samsung exynos5433/exynos4412 providers - removal of clkdev aliases on Samsung SoCs - convert clk-gpio to use gpio descriptors - various driver cleanups to match kernel coding style - Amlogic Video Processing Unit VPU and VAPB clks - sigma-delta modulation for Allwinner audio PLLs - Allwinner A83t Display clks - support for the second display unit clock on Renesas RZ/G1E - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR - new clock ids for Rockchip rk3188 and rk3368 SoCs - various 'const' markings on clk_ops structures - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: stm32h7: fix test of clock config clk: pxa: fix building on older compilers clk: sunxi-ng: a83t: Fix i2c buses bits clk: ti: dra7-atl-clock: fix child-node lookups clk: qcom: common: fix legacy board-clock registration clk: uniphier: fix DAPLL2 clock rate of Pro5 clk: uniphier: fix parent of miodmac clock data clk: hi3798cv200: correct parent mux clock for 'clk_sdio0_ciu' clk: hisilicon: Delete an error message for a failed memory allocation in hisi_register_clkgate_sep() clk: hi3660: fix incorrect uart3 clock freqency clk: kona-setup: Delete error messages for failed memory allocations ARC: clk: fix spelling mistake: "configurarion" -> "configuration" clk: cdce925: remove redundant check for non-null parent_name clk: versatile: Improve sizeof() usage clk: versatile: Delete error messages for failed memory allocations clk: ux500: Improve sizeof() usage clk: ux500: Delete error messages for failed memory allocations clk: spear: Delete error messages for failed memory allocations clk: ti: Delete error messages for failed memory allocations clk: mmp: Adjust checks for NULL pointers ...
