2017-02-28T11:06:10Z

All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update code where relevant to move away from virt_to_phys(). Acked-by: Russell King Reviewed-by: Laura Abbott Signed-off-by: Florian Fainelli Signed-off-by: Russell King

mvebu: make mvebu_armada375_smp_wa_init() static

The mvebu_armada375_smp_wa_init() is not exported or declared anywhere, so make it static to fix the following warning: arch/arm/mach-mvebu/system-controller.c:130:6: warning: symbol 'mvebu_armada375_smp_wa_init' was not declared.

ARM: mvebu: build armada375-smp code conditionally

2015-02-18T11:20:29Z

mvebu_armada375_smp_wa_init is only used on armada 375 but is defined for all mvebu machines. As it calls a function that is only provided sometimes, this can result in a link error: arch/arm/mach-mvebu/built-in.o: In function `mvebu_armada375_smp_wa_init': :(.text+0x228): undefined reference to `mvebu_setup_boot_addr_wa' To solve this, we can just change the existing #ifdef around the function to also check for Armada375 SMP platforms.

ARM: mvebu: use the common function for Armada 375 SMP workaround

2014-07-24T11:46:10Z

Use the common function mvebu_setup_boot_addr_wa() introduced in the commit "ARM: mvebu: Add a common function for the boot address work around" instead of the dedicated version for Armada 375. This commit also moves the workaround in the system-controller module. Indeed the workaround on 375 is really related to setting the boot address which is done by the system controller. As a bonus we no longer use an harcoded value to access the register storing the boot address.

ARM: mvebu: Use system controller to get the soc id when possible

2014-06-30T17:40:59Z

On Armada 38x it is possible to get the SoC Id and the revision without using the PCI register. Accessing the PCI registers implies enabling its clock and, because of the initialization issue, not keeping them enable. So if possible it is better to avoid it. Armada 370 and Armada XP provides the SoC ID values from the system controller but not the revision. Armada 375 provides both but the SoC ID value looks buggy (0x6660 instead of 0x6720).

ARM: mvebu: add function to set the resume boot address for Armada 375

2014-05-08T16:08:14Z

In order to boot the secondary CPUs on Armada 375, we need to set the boot address of these CPUs, through a register part of the System Controller (this deviates from the Armada XP design, where the boot address was defined using a register part of the PMSU unit). Therefore, this commit adds a new helper function in the System Controller driver to set the secondary CPU boot address. Moreover, it moves the System Controller initialization as an early_initcall(), since arch_initcall() is too late for an SMP-related initialization.

ARM: mvebu: add Armada 375 support to the system-controller driver

2014-02-22T00:41:09Z

The system controller block in the Armada 375 has different register offsets for the system reset and other related functions. Therefore, this commit introduces the new "armada-375-system-controller" compatible string to identify the Armada 375 variant of the system controller.

ARM: mvebu: make use of of_find_matching_node_and_match

Instead of the of_find_matching_node()/of_match_node() pair, which requires two iterations through the match table, make use of of_find_matching_node_and_match(), which only iterates through the table once. While we're here, mark the of_system_controller table const. Signed-off-by: Josh Cartwright Reviewed-by: Thomas Petazzoni Acked-by: Gregory CLEMENT Signed-off-by: Jason Cooper
