On SAMA7G5 the prescaler part of master clock has been implemented as a changeable one. Everytime the prescaler is changed the PMC_SR.MCKRDY bit must be polled. Value 1 for PMC_SR.MCKRDY means the prescaler update is done. Driver polls for this bit until it becomes 1. On SAMA7G5 it has been discovered that in some conditions the PMC_SR.MCKRDY is not rising but the rate it provides it's stable. The workaround is to add a timeout when polling for PMC_SR.MCKRDY. At the moment, for SAMA7G5, the prescaler will be removed from Linux clock tree as all the frequencies for CPU could be obtained from PLL and also there will be less overhead when changing frequency via DVFS.

SAMA7G5 supports DVFS by changing cpuck. On SAMA7G5 mck0 shares the same parent with cpuck as seen in the following clock tree: +----------> cpuck | FRAC PLL ---> DIV PLL -+-> DIV ---> mck0 mck0 could go b/w 32KHz and 200MHz on SAMA7G5. To avoid mck0 overclocking while changing FRAC PLL or DIV PLL the commit implements a notifier for mck0 which applies a safe divider to register (maximum value of the divider which is 5) on PRE_RATE_CHANGE events (such that changes on PLL to not overclock mck0) and sets the maximum allowed rate on POST_RATE_CHANGE events.

SAM9X60's PLL which is also part of SAMA7G5 is composed of 2 parts: one fractional part and one divider. On SAMA7G5 the CPU PLL could be changed at run-time to implement DVFS. The hardware clock tree on SAMA7G5 for CPU PLL is as follows: +---- div1 ----------------> cpuck | FRAC PLL ---> DIV PLL -+-> prescaler ---> div0 ---> mck0 The div1 block is not implemented in Linux; on prescaler block it has been discovered a bug on some scenarios and will be removed from Linux in next commits. Thus, the final clock tree that will be used in Linux will be as follows: +-----------> cpuck | FRAC PLL ---> DIV PLL -+-> div0 ---> mck0 It has been proposed in [1] to not introduce a new CPUFreq driver but to overload the proper clock drivers with proper operation such that cpufreq-dt to be used. To accomplish this DIV PLL and div0 implement clock notifiers which applies safe dividers before FRAC PLL is changed. The current commit treats only the DIV PLL by adding a notifier that sets a safe divider on PRE_RATE_CHANGE events. The safe divider is provided by initialization clock code (sama7g5.c). The div0 is treated in next commits (to keep the changes as clean as possible).

SAMA7G5 has 4 master clocks (MCK1..4) which are controlled though the register at offset 0x30 (relative to PMC). In the last/first phase of suspend/resume procedure (which is architecture specific) the parent of master clocks are changed (via assembly code) for more power saving (see file arch/arm/mach-at91/pm_suspend.S, macros at91_mckx_ps_enable and at91_mckx_ps_restore). Thus the macros corresponding to register at offset 0x30 need to be shared b/w clk-master.c and pm_suspend.S. commit ec03f18c ("clk: at91: add register definition for sama7g5's master clock") introduced the proper macros but didn't adapted the clk-master.c as well. Thus, this commit adapt the clk-master.c to use the macros introduced in commit ec03f18c ("clk: at91: add register definition for sama7g5's master clock").

Before going to backup mode architecture specific PM code sets the first word in securam (file arch/arm/mach-at91/pm.c, function at91_pm_begin()).

SAMA5D2 and SAMA7G5 have a special power saving mode (backup mode) where most of the SoC's components are powered off (including PMC). Resuming from this mode is done with the help of bootloader. Peripherals are not aware of the power saving mode thus most of them are disabling clocks in proper suspend API and re-enable them in resume API without taking into account the previously setup rate. Moreover some of the peripherals are acting as wakeup sources and are not disabling the clocks in this scenario, when suspending. Since backup mode cuts the power for peripherals, in resume part these clocks needs to be re-configured. The initial PMC suspend/resume code was designed only for SAMA5D2's PMC (as it was the only one supporting backup mode). SAMA7G supports also backup mode and its PMC is different (few new functionalities, different registers offsets, different offsets in registers for each functionalities). To address both SAMA5D2 and SAMA7G5 PMC add .save_context()/.resume_context() support to each clocks driver and call this from PMC driver.

The Ux500 PRCC (peripheral reset and clock controller) can also control reset of the IP blocks, not just clocks. As the PRCC is probed as a clock controller and we have other platforms implementing combined clock and reset controllers, follow this pattern and implement the PRCC rest controller as part of the clock driver. The reset controller needs to be selected from the machine as Ux500 has traditionally selected its mandatory subsystem prerequisites from there.

This rewrites the ux500/u8500 clock bindings in YAML schema and extends them with the PRCC reset controller. The bindings are a bit idiomatic but it just reflects their age, the ux500 platform was used as guinea pig for early device tree conversion of platforms in 2015. The new subnode for the reset controller follows the pattern of the old bindings and adds a node with reset-cells for this.

On sm8250 dispcc and videocc registers are powered up by the MMCX power domain. Currently we use a regulator to enable this domain on demand, however this has some consequences, as genpd code is not reentrant.

Add support for the camera clock controller found on SC7280 based devices. This would allow camera drivers to probe and control their clocks.

As also shown on downstream dts[1], for a correct operation of the Venus block, we have to retain MEM/PERIPH when halting the video_core, video_axi and video_subcore0 branches: add these CXCs to the main Venus GDSC.
