2019-12-11clk: imx: Replace all the clk based helpers with macrosAbel Vesa1-27/+12
Replacing with macros all the clk based API helpers we reduce the code duplication. The end goal is to get rid of all these macros when there will be no more users of the clk based API, that is, when all the i.MX clock provider drivers will be switched completely to the clk_hw based API. This is another step in moving away from the non clk_hw based API usage throughout the i.MX clock drivers. The reason for doing that is to have a clear split between the clock provider and the clock consumer API.

2019-12-11clk: imx: Add correct failure handling for clk based helpersAbel Vesa1-15/+22
If the clk_hw based API returns an error, trying to return the clk from hw will end up in a NULL pointer dereference. So adding the to_clk checker and using it inside every clk based macro helper we handle that case correctly. This to_clk is also temporary and will go away along with the clk based macro helpers once there is no user that need them anymore.

2019-12-09clk: imx8m: Suppress bind attrsLeonard Crestez3-0/+15
The clock drivers on imx8m series are registered as platform devices and this opens the possibility of reloading the driver at runtime. This doesn't actually work: clocks are never removed and attempting to bind again results in registration errors and a crash. Almost all devices depend on clocks anyway so rebinding is unlikely to ever be useful Fix this by explicitly suppressing bind attrs like several other clock drivers.

2019-12-09clk: imx: Mark dram pll on 8mm and 8mn with CLK_GET_RATE_NOCACHELeonard Crestez4-2/+10
DRAM frequency switches are executed in firmware and can change the configuration of the DRAM PLL outside linux. Mark these CLKs with CLK_GET_RATE_NOCACHE so we always read back the PLL config registers and recalculate rates. In current DRAM frequency tables on 8mm/8mn only the maximum frequency uses the PLL so it's always configured in the same way. However reading back the PLL configuration is the correct behavior and allows additional setpoints in the future.

These clocks are only modified as part of DRAM frequency switches during which DRAM itself is briefly inaccessible. The switch is performed with a SMC call to by TF-A which runs from a SRAM area; upon returning to linux several clocks bits are modified and we need to update them. For rate bits an easy solution is to just mark with CLK_GET_RATE_NOCACHE so that new rates are always read back from registers.

Pull clk updates from Stephen Boyd: "This merge window we have one small clk provider API in the core framework and then a bunch of driver updates and a handful of new drivers. In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here.

2019-11-04clk: imx: imx8mq: fix sys3_pll_out_selsPeng Fan1-2/+2
It is not correct that sys3_pll_out use sys2_pll1_ref_sel as parent. According to the current imx_clk_sccg_pll design, it uses both bypass1/2, however set bypass2 as 1 is not correct, because it will make sys[x]_pll_out use wrong parent and might access wrong registers. So correct bypass2 to 0 and fix sys3_pll_out_sels.

2019-10-28clk: imx7ulp: do not export out IMX7ULP_CLK_MIPI_PLL clockFancy Fang1-2/+1
The mipi pll clock comes from the MIPI PHY PLL output, so it should not be a fixed clock. MIPI PHY PLL is in the MIPI DSI space, and it is used as the bit clock for transferring the pixel data out and its output clock is configured according to the display mode. So it should be used only for MIPI DSI and not be exported out for other usages. Signed-off-by: Fancy Fang <chen.fang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2019-10-28clk: imx8m: Use SYS_PLL1_800M as intermediate parent of CLK_ARMLeonard Crestez2-2/+2
During cpu frequency switching the main "CLK_ARM" is reparented to an intermediate "step" clock. On imx8mm and imx8mn the 24M oscillator is used for this purpose but it is extremely slow, increasing wakeup latencies to the point that i2c transactions can timeout and system becomes unresponsive. Fix by switching the "step" clk to SYS_PLL1_800M, matching the behavior of imx8m cpufreq drivers in imx vendor tree. This bug was not immediately apparent because upstream arm64 defconfig uses the "performance" governor by default so no cpufreq transitions happen.
