* ARM: dts: mmp2-olpc-xo-1-75: clear the warnings when make dtbsZhen Lei2020-12-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The check_spi_bus_bridge() in scripts/dtc/checks.c requires that the node have "spi-slave" property must with "#address-cells = <0>" and "#size-cells = <0>". But currently both "#address-cells" and "#size-cells" properties are deleted, the corresponding default values are 2 and 1. As a result, the check fails and below warnings is displayed. arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): \ /soc/apb@d4000000/spi@d4037000: incorrect #address-cells for SPI bus also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3 arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): \ /soc/apb@d4000000/spi@d4037000: incorrect #size-cells for SPI bus also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3 arch/arm/boot/dts/mmp2-olpc-xo-1-75.dtb: Warning (spi_bus_reg): \ Failed prerequisite 'spi_bus_bridge' Because the value of "#size-cells" is already defined as zero in the node "ssp3: spi@d4037000" in arch/arm/boot/dts/mmp2.dtsi. So we only need to explicitly add "#address-cells = <0>" and keep "#size-cells" no change.

* ARM: keystone: remove SECTION_SIZE_BITS/MAX_PHYSMEM_BITSArnd Bergmann2020-12-071-3/+0
| | | | | | | | | | | | | | | | | | | | | | | These definitions are evidently left over from the days when sparsemem settings were platform specific. This was no longer the case when the platform got merged. There was no warning in the past, but now the asm/sparsemem.h header ends up being included indirectly, causing this warning: In file included from /git/arm-soc/arch/arm/mach-keystone/keystone.c:24: arch/arm/mach-keystone/memory.h:10:9: warning: 'SECTION_SIZE_BITS' macro redefined [-Wmacro-redefined] #define SECTION_SIZE_BITS 34 ^ arch/arm/include/asm/sparsemem.h:23:9: note: previous definition is here #define SECTION_SIZE_BITS 28 ^ Clearly the definitions never had any effect here, so remove them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DCDC1 regulator powers many different subsystems. While some of them can work at 3.0 V, some of them can not. For example, VCC-HDMI can only work between 3.24 V and 3.36 V. According to OS images provided by the board manufacturer this regulator should be set to 3.3 V.

To make it easier to control this, hoist this warning into Kconfig and the main Makefile so that disabling it is simpler, as the warning will only be enabled in a couple places (main Makefile and a couple of compressed boot folders that blow away LDFLAGS_vmlinx) and making it conditional is easier due to Kconfig syntax. One small additional benefit of this is saving a call to ld-option on incremental builds because we will have already evaluated it for CONFIG_LD_ORPHAN_WARN. To keep the list of supported architectures the same, introduce CONFIG_ARCH_WANT_LD_ORPHAN_WARN, which an architecture can select to gain this automatically after all of the sections are specified and size asserted. A special thanks to Kees Cook for the help text on this config.

Since we are approaching to deprecate 32bit machines and already made the config option available for only builtin build since v5.8, lastly it has been not default option in zsmalloc, it's time to drop the option for better maintenance.

Switch all arch_cpu_idle() implementations to use raw_local_irq_{en,dis}able() and carefully manage the lockdep,rcu,tracing state like we do in entry.

The same problem will be hit on all 32-bit architectures that have a physical address space larger than 4GB and happen to not enable sparsemem and include asm/sparsemem.h from asm/pgtable.h. After the initial discussion, I suggested just always defining MAX_POSSIBLE_PHYSMEM_BITS whenever CONFIG_PHYS_ADDR_T_64BIT is set, or provoking a build error otherwise. This addresses all configurations that can currently have this runtime bug, but leaves all other configurations unchanged. I looked up the possible number of bits in source code and datasheets, here is what I found: - on ARC, CONFIG_ARC_HAS_PAE40 controls whether 32 or 40 bits are used - on ARM, CONFIG_LPAE enables 40 bit addressing, without it we never support more than 32 bits, even though supersections in theory allow up to 40 bits as well. - on MIPS, some MIPS32r1 or later chips support 36 bits, and MIPS32r5 XPA supports up to 60 bits in theory, but 40 bits are more than anyone will ever ship - On PowerPC, there are three different implementations of 36 bit addressing, but 32-bit is used without CONFIG_PTE_64BIT - On RISC-V, the normal page table format can support 34 bit addressing. There is no highmem support on RISC-V, so anything above 2GB is unused, but it might be useful to eventually support CONFIG_ZRAM for high pages.

We should not override the cpuidle states with a hardcoded PWRDM_POWER_ON value. Instead, we should use a configured idle state that does not cause the context to be lost. Otherwise we end up configuring a potentially improper state for the MPUSS. We also want to update the returned state index for the selected state. Let's just select the highest power idle state C1 to ensure no context loss is allowed on cpu_cluster_pm_enter() errors. With these changes we can now unconditionally call omap4_enter_lowpower() for WFI like we did earlier before commit 55be2f50336f ("ARM: OMAP2+: Handle errors for cpu_pm"). And we can return the selected state index.

In the MMU on case, we remain in HYP mode as configured by the firmware, and rely on the fact that any HVC instruction issued in this mode will be dispatched via the SVC slot in the HYP vector table. However, this slot will point to a Thumb2 symbol if the kernel is built in Thumb2 mode, and so we have to configure HSCTLR to ensure that the exception handlers are invoked in Thumb2 mode as well.

The mv88e6352 supports an MDIO clock of 12MHz. However the older 88e6185 does not like 12MHz, and often fails to probe. Reduce the clock speed to 5MHz, which seems to work reliably.
