2019-01-07clk: rockchip: fix frac settings of GPLL clock for rk3328Katsuhiro Suzuki1-6/+6
This patch fixes settings of GPLL frequency in fractional mode for rk3328. In this mode, FOUTVCO is calcurated by following formula: FOUTVCO = FREF * FBDIV / REFDIV + ((FREF * FRAC / REFDIV) >> 24) The problem is in FREF * FRAC >> 24 term. This result always lacks one from target value is specified by rate member. For example first itme of rk3328_pll_frac_rate originally has - rate : 1016064000 - refdiv: 3 - fbdiv : 127 - frac : 134217 - FREF * FBDIV / REFDIV = 1016000000 - (FREF * FRAC / REFDIV) >> 24 = 63999 Thus calculated rate is 1016063999. It seems wrong. If frac has 134218 (it is increased 1 from original value), second term is 64000. All other items have same situation. So this patch adds 1 to frac member in all items of rk3328_pll_frac_rate.

2018-08-06clk: rockchip: Add pclk_rkpwm_pmu to PMU critical clocks in rk3399Levin Du1-0/+1
PWM2 is commonly used to control voltage of PWM regulator of VDD_LOG in RK3399. On the Firefly-RK3399 board, PWM2 outputs 40 KHz square wave from power on and the VDD_LOG is about 0.9V. When the kernel boots normally into the system, the PWM2 keeps outputing PWM signal. But the kernel hangs randomly after "Starting kernel ..." line on that board. When it happens, PWM2 outputs high level which causes VDD_LOG drops to 0.4V below the normal operating voltage. By adding "pclk_rkpwm_pmu" to the rk3399_pmucru_critical_clocks array, PWM clock is ensured to be prepared at startup and the PWM2 output is normal. After repeated tests, the early boot hang is gone. This patch works on both Firefly-RK3399 and ROC-RK3399-PC boards. Signed-off-by: Levin Du <djw@t-chip.com.cn> Signed-off-by: Heiko Stuebner <heiko@sntech.de>

2018-05-23clk: rockchip: remove deprecated gate-clk code and dt-bindingHeiko Stuebner2-99/+0
Initially we tried modeling clocks via the devicetree before switching to clocks declared in the clock drivers and only exporting specific ids to the devicetree. As the old code was in the kernel for 1-2 releases when the new mode of operation was added we kept it for backwards compatibility. That deprecation notice is in the binding since july 2014, so nearly 4 years now and I think it's time to drop the old cruft. Especially as at the time using the mainline kernel on Rockchip devices was not really possible, except for experiments on the really old socs of the rk3066 + rk3188 line, so there shouldn't be any devicetrees still around that rely on that code.

There are many factors affecting the clock phase, including clock rate, temperature, logic voltage and silicon process, etc. But clock rate is the most significant one here, and the driver should be aware of the change of the clock rate.

The MMC sample and drv clock for rockchip platforms are derived from the bus clock output to the MMC/SDIO card. So it should never happens that the clk rate is zero given it should inherits the clock rate from its parent. If something goes wrong and makes the clock rate to be zero, the calculation would be wrong but may still make the mmc tuning process work luckily.

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.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2017-08-08clk: rockchip: add special approximation to fix up fractional clk's jitterElaine Zhang1-0/+36
>From Rockchips fractional divider description: 3.1.9 Fractional divider usage To get specific frequency, clocks of I2S, SPDIF, UARTcan be generated by fractional divider. Generally you must set that denominator is 20 times larger than numerator to generate precise clock frequency. So the fractional divider applies only to generate low frequency clock like I2S, UART. Therefore add a special approximation function that handles this special requirement. Signed-off-by: Elaine Zhang <zhangqing@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
