The only part of plat-samsung that is shared with arch-exynos is the CPU identification code.

2020-08-19ARM: samsung: make pm-debug platform independentArnd Bergmann
The pm-debug code is one of the few things shared between s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210 independent of plat-samsung, change the common bits of this code to no longer reference the s3c specific bits. In particular, all the CPU checks need to be moved out of the common code into platform specific files.

2020-08-19ARM: samsung: remove s3c_pm_debug_init()Arnd Bergmann
On s3c24xx and s3c64xx, this is just a wrapper around s3c_pm_debug_init_uart(), but this function does not exist on s5pv210, which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally not set. In a configuration that supports both s5pv210 and s3c64xx, we would always call the s3c64xx function, which is probably incorrect when running on s5pv210. Remove the function call completely on s5pv210 and skip the wrapper on s3c as a cleanup. As a side-effect, the s3c64xx behavior is now always the same, regardless of whether it is a DT-only configuration or both DT and ATAGS are supported for booting.

There is no real phy driver, so s3c-hsudc just pokes the registers itself. Improve this a little by making it a platform data callback like we do for gpios.

2020-08-19ARM: s3c24xx: simplify mach/io.hArnd Bergmann
s3c24xx has a custom implementation of the inb/outb family of I/O accessors, implementing both general register access and ISA I/O port through a multiplexer. As far as I can tell, the first case has never been needed, and certainly is not used now, as drivers only use inb/outb to actually driver ISA or PCI port I/O. Similarly, the special ISA support is limited to a single machine, the Simtec Electronics BAST (EB2410ITX) with its PC/104 expansion connector, all other machines could simply use the generic implementation from asm/io.h that expects a single memory-mapped address range for byte, word and dword access. As no other machines besides BAST actually selects CONFIG_ISA, this is likely not even necessary. As a cleanup, remove support for the non-ISA access from the helpers, and make the ISA access use the virtual address window that we use elsewhere for PCI I/O ports. In configurations without the BAST machine, this now falls back on the generic implementation from asm/io.h, but the mach/io.h header is still relied on to include a number of other header files implicitly.

A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not really needed and the s3c24xx watchdog driver can depend on Samsung ARM architectures instead. The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung platforms are here exceptions. All others just depend on CONFIG_ARCH_xxx.

2020-08-19ARM, sched/topology: Revert back to default scheduler topologyValentin Schneider
The ARM-specific GMC level is meant to be built using the thread sibling mask, but no devicetree in arch/arm/boot/dts uses the 'thread' cpu-map binding. With SD_SHARE_POWERDOMAIN gone, this topology level can be removed, at which point ARM no longer benefits from having a custom defined topology table. Delete the GMC topology level by making ARM use the default scheduler topology table.

2020-08-19ARM: dts: omap3: Add cpu trips and cooling map for omap34/36 familiesAdam Ford
Currently, OMAP3_THERMAL is disabled by default, so the bandgap sensor is unavailable, and enabling it will somewhat increase power consumption. However for boards which operate near their thermal limit, OMAP3_THERMAL can be enabled and monitored to keep the processor from either running too fast, or shutdown when it's deemed to be operating at an unsafe thermal limit at the expense of increased power consumption. The OMAP3530, OMAP3630, and DM3730 all show thresholds of 90C and 105C depending on commercial or extended temperature ratings. This patch expands the thermal information to include the limits of 80C for alert and 90C critical based on commercial temperature rating. It sets the coolings-cells for the 34xx and 36xx CPU's which will start to throttle back their maximum frequency when the bangap sensor reads above the alert temerature of 80C. For boards who which to increase the temperatures for extended temperature ratings, these can be changed on their respective device trees with something like: &cpu_alert0 { temperature = <90000>; /* millicelsius */ }; &cpu_crit { temperature = <105000>; /* millicelsius */ }; Signed-off-by: Adam Ford <aford173@gmail.com> Tested-by: H.

2020-08-18ARM: dts: Configure am3 and am4 sgx for genpd and drop platform dataTony Lindgren
We can power off the SGX power domain when not in use when we configure it for genpd. And with that change, we can now also drop the old unused legacy platform data.

2020-08-18soc: ti: omap-prm: Add basic power domain supportTony Lindgren
The PRM controller has currently only support for resets while the power domains are still handled in the platform code. Let's add basic power domain support to enable and disable a PRM controlled power domain if configured in the devicetree. This can be used for various hardware accelerators, and interconnect instances. Further support can be added later on as needed for runtime configuration based on domain-idle-states.

2020-08-17ARM: dts: exynos: add prefetch properties for L2C-310 cacheGuillaume Tucker
Add the devicetree properties to enable instruction and data prefetch on exynos4210 and exynos4412 which use the L2C-310 cache. No other Exynos chip appears to be using this L2 cache hardware. This follows the default bits being set in the l2c_aux_val register for the Exynos platform, which can now be cleared as a result.

2020-08-17ARM: exynos: clear L310_AUX_CTRL_NS_LOCKDOWN in default l2c_aux_valGuillaume Tucker
The L310_AUX_CTRL_NS_LOCKDOWN flag is set during the L2C enable sequence. There is no need to set it in the default register value, this was done before support for it was implemented in the code. It is not set in the hardware initial value either. Clean this up by removing this flag from the default l2c_aux_val, and add it to the l2c_aux_mask to print an alert message if it was already set before the kernel initialisation.
