2022-05-17clk: bcm2835: fix bcm2835_clock_choose_divStefan Wahren
The commit 09e3b18ca5de ("clk: bcm2835: Remove unused variable") accidentially breaks the behavior of bcm2835_clock_choose_div() and booting of Raspberry Pi. The removed do_div macro call had side effects, so we need to restore it.

2022-05-07ARM: pxa: move clk register definitions to driverArnd Bergmann
The clock register definitions are now used (almost) exclusively in the clk driver, and that relies on no other mach/*.h header files any more. Remove the dependency on mach/pxa*-regs.h by addressing the registers as offsets from a void __iomem * pointer, which is either passed from a board file, or (for the moment) ioremapped at boot time from a hardcoded address in case of DT (this should be moved into the DT of course).

2022-05-06clk: sunxi-ng: h616: Add PLL derived 32KHz clockAndre Przywara
The RTC section of the H616 manual mentions in a half-sentence the existence of a clock "32K divided by PLL_PERI(2X)". This is used as one of the possible inputs for the mux that selects the clock for the 32 KHz fanout pad. On the H616 this is routed to pin PG10, and some boards use that clock output to compensate for a missing 32KHz crystal. On the OrangePi Zero2 this is for instance connected to the LPO pin of the WiFi/BT chip. The new RTC clock binding requires this clock to be named as one input clock, so we need to expose this to the DT. In contrast to the D1 SoC there does not seem to be a gate for this clock, so just use a fixed divider clock, using a newly assigned clock number.

2022-05-06clk: sunxi-ng: h6-r: Add RTC gate clockAndre Przywara
The H6 and H616 feature an (undocumented) bus clock gate for accessing the RTC registers. This seems to be enabled at reset (or by the BootROM), so we got away without it so far, but exists regardless. Since the new RTC clock binding for the H616 requires this "bus" clock to be specified in the DT, add this to R_CCU clock driver and expose it on the DT side with a new number. We do this for both the H6 and H616, but mark it as IGNORE_UNUSED, as we cannot reference it in any H6 DTs.

2022-05-04clk: tegra: Register clocks from root to leafTimo Alho
Current clock initialization causes intermediate registering of orphan clocks (i.e. a clock without a parent registered). CCF keeps track of orphan clocks and any time a new clock is registered, it will loop through the list of orphan and queries if the parent is now available. This operation triggers one or more clock operations, which are IPCs with BPMP-FW. Hence, due to the order in which the clocks appear currently, this causes > 5000 IPC messages to be sent to BPMP-FW during clock initialization. Optimize the clock probing by registering clocks hierarchically from root clock towards leafs.

2022-05-03clk: rockchip: Mark hclk_vo as critical on rk3568Sascha Hauer
Whenever pclk_vo is enabled hclk_vo must be enabled as well. This is described in the Reference Manual as: | 2.8.6 NIU Clock gating reliance | | A part of niu clocks have a dependence on another niu clock in order to | sharing the internal bus. When these clocks are in use, another niu | clock must be opened, and cannot be gated. These clocks and the special | clock on which they are relied are as following: | | Clocks which have dependency The clock which can not be gated | ----------------------------------------------------------------- | ... | pclk_vo_niu, hclk_vo_s_niu hclk_vo_niu | ... The clock framework doesn't offer a way to enable clock B whenever clock A is enabled, at least not when B is not an ancestor of A. Workaround this by marking hclk_vo as critical so it is never disabled. This is suboptimal in terms of power consumption, but a stop gap solution until the clock framework has a way to deal with this. We have this clock tree: | aclk_vo 2 2 0 300000000 0 0 50000 Y | aclk_hdcp 0 0 0 300000000 0 0 50000 N | pclk_vo 2 3 0 75000000 0 0 50000 Y | pclk_edp_ctrl 0 0 0 75000000 0 0 50000 N | pclk_dsitx_1 0 0 0 75000000 0 0 50000 N | pclk_dsitx_0 1 2 0 75000000 0 0 50000 Y | pclk_hdmi_host 1 2 0 75000000 0 0 50000 Y | pclk_hdcp 0 0 0 75000000 0 0 50000 N | hclk_vo 2 5 0 150000000 0 0 50000 Y | hclk_hdcp 0 0 0 150000000 0 0 50000 N | hclk_vop 0 2 0 150000000 0 0 50000 N Without this patch the edp, dsitx, hdmi and hdcp driver would enable their clocks which then enables pclk_vo, but hclk_vo stays disabled and register accesses just hang. hclk_vo is enabled by the VOP2 driver, so reproducibility of this issue depends on the probe order.

2022-05-02clk: imx: scu: Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usageMiaoqian Lin
If the device is already in a runtime PM enabled state pm_runtime_get_sync() will return 1. Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync() fails, so use pm_runtime_resume_and_get() instead. this function will handle this.
