* ARM: kirkwood: remove lagacy clk workaroundsSebastian Hesselbarth2013-11-241-37/+1Star
| | | | | | | | | | | With legacy devices converted to DT and a proper ethernet MAC workaround, we can now remove the clk workarounds for legacy devices. While at it, also cleanup the list of includes.

| | | | | | | | | | | | | | | | | | | | | | | | | | The ARM architected timer driver doesn't compile without GENERIC_CLOCKEVENTS selected, so ensure that we select it when building for a platform that has the timer. Without this patch, mach-virt fails to build without something like mach-vexpress also selected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uwe reported a build failure when targetting a NOMMU platform with my recent prefetch changes: arch/arm/lib/changebit.S: Assembler messages: arch/arm/lib/changebit.S:15: Error: architectural extension `mp' is not allowed for the current base architecture This is due to use of the .arch_extension mp directive immediately prior to an ALT_SMP(...) instruction. Whilst the ALT_SMP macro will expand to nothing if !CONFIG_SMP, gas will still choke on the directive. This patch fixes the issue by only emitting the sequence (including the directive) if CONFIG_SMP=y.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LPAE enabled kernels use the 64-bit version of TTBR0 and TTBR1 registers. If we're running an LPAE kernel, fill the upper half of TTBR0 with 0 because we're setting it to the idmap here (the idmap is guaranteed to be < 4Gb) and fully restore TTBR1 instead of just restoring the lower 32 bits. Failure to do so can cause failures on resume from suspend when these registers are only half restored.

| * ARM: 7882/1: mm: fix __phys_to_virt to work with 64 bit phys_addr_t in BE caseVictor Kamensky2013-11-141-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure that inline assembler that expects 'r' operand receives 32 bit value. Before this fix in case of CONFIG_ARCH_PHYS_ADDR_T_64BIT and CONFIG_ARM_PATCH_PHYS_VIRT __phys_to_virt function passed 64 bit value to __pv_stub inline assembler where 'r' operand is expected. Compiler behavior in such case is not well specified. It worked in little endian case, but in big endian case incorrect code was generated, where compiler confused which part of 64 bit value it needed to modify. For example BE snippet looked like this: N:0x80904E08 : MOV r2,#0 N:0x80904E0C : SUB r2,r2,#0x81000000 when LE similar code looked like this N:0x808FCE2C : MOV r2,r0 N:0x808FCE30 : SUB r2,r2,#0xc0, 8 ; #0xc0000000 Note 'r0' register is va that have to be translated into phys To avoid this situation use explicit cast to 'unsigned long', which explicitly discard upper part of phys address and convert value to 32 bit. Also add comment so such cast will not be removed in the future.

Introduce kvm_kaddr_to_phys which translates both types of valid kernel addresses to the corresponding physical address. At the same time resolves a typing issue where we were storing the physical address as a 32 bit unsigned long (on arm), truncating the physical address for addresses above the 4GB limit. This caused breakage on Keystone.

For a device such as i2c who uses autosuspend, it is possible to enter the suspend path with dev->power.runtime_status = RPM_ACTIVE. As part of the suspend flow, the generic runtime logic would increment it's dev->power.disable_depth to 1. This should prevent further pm_runtime_get_sync from succeeding once the runtime_status has been set to RPM_SUSPENDED. Now, as part of the suspend_noirq handler in omap_device, we force the following: if the device status is !suspended, we force the device to idle using omap_device_idle (clocks are cut etc..). This ensures that from a hardware perspective, the device is "suspended". However, runtime_status is left to be active. *if* an operation is attempted after this point to pm_runtime_get_sync, runtime framework depends on runtime_status to indicate accurately the device status, and since it sees it to be ACTIVE, it assumes the module is functional and returns a non-error value. As a result the user will see pm_runtime_get succeed, however a register access will crash due to the lack of clocks. To prevent this from happening, we should ensure that runtime_status exactly indicates the device status. As a result of this change any further calls to pm_runtime_get* would return -EACCES (since disable_depth is 1). On resume, we restore the clocks and runtime status exactly as we suspended with. These operations are not expected to fail as we update the states after the core runtime framework has suspended itself and restore before the core runtime framework has resumed.

This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC wakeup). The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or software reset. This means that their interrupts may be enabled during early boot if, for example, they where not disabled during a previous shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a user reset). Furthermore, an RTC or RTT-alarm may also be active. The RTC and RTT-interrupts use the shared system-interrupt line, which is also used by the PIT, and if an interrupt occurs before a handler (e.g. RTC-driver) has been installed this leads to the system interrupt being disabled and prevents the system from booting. Note that when boot hangs due to an early RTC or RTT-interrupt, the only way to get the system to start again is to remove the backup power (e.g. battery) or to disable the interrupt manually from the bootloader. In particular, a user reset is not sufficient. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: stable@vger.kernel.org # 3.11.x

This patch reorders the calls so the CPU reset handler code does not read an uninitialized variable.

We can't enable WM8750 in multi_v7_defconfig since it's a v6-based device, but it's still valuable to have an in-tree defconfig that is suitable for the hardware. This is based on multi_v7_defconfig and can be tweaked over time. It gets us off the ground for now. Naming it vt8500_v6_v7 similar to i.MX since there are v5-based vt8500 chips as well.
