All platform MSI users and the PCI/MSI code handle per device MSI domains when the irqdomain associated to the device provides MSI parent functionality. Remove the "global" platform domain related code and provide the MSI parent functionality by filling in msi_parent_ops. Signed-off-by:

The core infrastructure has everything in place to switch ICU to per device MSI domains and avoid the convoluted construct of the existing platform-MSI layering violation. The new infrastructure provides a wired interrupt specific interface in the MSI core which converts the 'hardware interrupt number + trigger type' allocation which is required for wired interrupts in the regular irqdomain code to a normal MSI allocation. The hardware interrupt number and the trigger type are stored in the MSI descriptor device cookie by the core code so the ICU specific code can retrieve them. The new per device domain is only instantiated when the irqdomain which is associated to the ICU device provides MSI parent functionality. Up to that point it invokes the existing code. Once the parent is converted the code for the current platform-MSI mechanism is removed. The new domain shares the interrupt chip callbacks and the translation function. The only new functionality aside of filling out the msi_domain_templates is a domain specific set_desc() callback, which will go away once all platform-MSI code has been converted. Signed-off-by:

The MBI chip creates two MSI domains: - PCI/MSI - Platform device domain Both have the MBI domain as parent and differ slightly in the interrupt chip callbacks and the platform device domain supports level type signaling. Convert it over to the MSI parent domain mechanism by: - Providing the required templates - Implementing a custom init_dev_msi_info() callback which sets the chip callbacks and the level support flags depending on the domain bus token type of the per device domain.

Similar to the previous conversion of the PCI/MSI support lift the prepare() callback from the existing platform MSI code and enable platform MSI and the related device domain bus tokens in select and the child domain initialization code. All platform MSI users are automatically using the new per device MSI model now. Signed-off-by:

Add the prerequisites for DEVICE MSI into the shared select() and child domain init function. These domains are really trivial and just provide a custom irq chip callback to write the MSI message. Signed-off-by:

Thomas Gleixner authored
The its_pci_msi_prepare() function from the ITS-PCI/MSI code provides the 'global' PCI/MSI domains. Move this function to the ITS-MSI parent code and amend the function to use the domain hardware size, which is the MSI[X] vector count, for allocating the ITS slots for the PCI device. Enable PCI matching in msi_parent_ops and provide the necessary update to the ITS specific child domain initialization function so that the prepare callback gets invoked on allocations. The latter might be optimized to do the allocation right at the point where the child domain is initialized, but keep it simple for now. Signed-off-by:

Add the bus tokens for DOMAIN_BUS_PCI_DEVICE_MSI and DOMAIN_BUS_PCI_DEVICE_MSIX to the common child init function. Provide the match mask which can be used by parent domain implementation so the bitmask based child bus token match works. Signed-off-by:

Thomas Gleixner authored
To support per device MSI domains the ITS must provide MSI parent domain functionality. Provide the basic skeleton for this: - msi_parent_ops - child domain init callback - the MSI parent flag set in irqdomain::flags This does not make ITS a functional parent domain as there is no bit set in the bus_select_mask yet, but it provides the base to implement PCI and platform MSI support gradually on top.

Thomas Gleixner authored
All irqdomains which provide MSI parent domain functionality for per device MSI domains need to provide a select() callback for the irqdomain and a function to initialize the child domain. Most of these functions would just be copy&paste with minimal modifications, so provide a library function which implements the required functionality and is customizable via parent_domain::msi_parent_ops. The check for the supported bus tokens in msi_lib_init_dev_msi_info() is expanded step by step within the next patches. Signed-off-by:

Most ARM(64) PCI/MSI domains mask and unmask in the parent domain after or before the PCI mask/unmask operation takes place. So there are more than a dozen of the same wrapper implementation all over the place. Don't make the same mistake with the new per device PCI/MSI domains and provide a new MSI feature flag, which lets the domain implementation enable this sequence in the PCI/MSI code. Signed-off-by:

Pull clk fix from Stephen Boyd: "One fix for the SiFive PRCI clocks so that the device boots again. This driver was registering clkdev lookups that were always going to be useless. This wasn't a problem until clkdev started returning an error in these cases, causing this driver to fail probe, and thus boot to fail because clks are essential for most drivers. The fix is simple, don't use clkdev because this is a DT based system where clkdev isn't used" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: sifive: Do not register clkdevs for PRCI clocks
