2019-07-11mailbox: omap: Add support for TI K3 SoCsSuman Anna2-18/+27
The TI K3 AM65x and J721E family of SoCs have a new Mailbox IP that is based on the existing Mailbox IP present in OMAP architecture based SoCs. Each instance of the legacy OMAP Mailbox IP is now a single cluster within the newer Mailbox IP instance on K3 architecture based SoCs. A single K3 Mailbox IP instance has multiple clusters with each cluster providing the same functionality as the existing OMAP Mailbox IP. Reuse the existing OMAP Mailbox driver to extend the support for this newer IP present within the Main NavSS block on K3 SoCs. The K3 family of SoCs use 64-bit ARMv8 processors for running Linux, so the driver is also enhanced to deal with the differences between the 32-bit message payloads and the 64-bit pointers used by the client drivers.

Now that we've gotten rid of clk_readl() we can remove io.h from the clk-provider header and push out the io.h include to any code that isn't already including the io.h header but using things like readl/writel, etc. Found with this grep: git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \ xargs git grep -l \ -e '\<__iowrite32_copy\>' --or \ -e '\<__ioread32_copy\>' --or \ -e '\<__iowrite64_copy\>' --or \ -e '\<ioremap_page_range\>' --or \ -e '\<ioremap_huge_init\>' --or \ -e '\<arch_ioremap_pud_supported\>' --or \ -e '\<arch_ioremap_pmd_supported\>' --or \ -e '\<devm_ioport_map\>' --or \ -e '\<devm_ioport_unmap\>' --or \ -e '\<IOMEM_ERR_PTR\>' --or \ -e '\<devm_ioremap\>' --or \ -e '\<devm_ioremap_nocache\>' --or \ -e '\<devm_ioremap_wc\>' --or \ -e '\<devm_iounmap\>' --or \ -e '\<devm_ioremap_release\>' --or \ -e '\<devm_memremap\>' --or \ -e '\<devm_memunmap\>' --or \ -e '\<__devm_memremap_pages\>' --or \ -e '\<pci_remap_cfgspace\>' --or \ -e '\<arch_has_dev_port\>' --or \ -e '\<arch_phys_wc_add\>' --or \ -e '\<arch_phys_wc_del\>' --or \ -e '\<memremap\>' --or \ -e '\<memunmap\>' --or \ -e '\<arch_io_reserve_memtype_wc\>' --or \ -e '\<arch_io_free_memtype_wc\>' --or \ -e '\<__io_aw\>' --or \ -e '\<__io_pbw\>' --or \ -e '\<__io_paw\>' --or \ -e '\<__io_pbr\>' --or \ -e '\<__io_par\>' --or \ -e '\<__raw_readb\>' --or \ -e '\<__raw_readw\>' --or \ -e '\<__raw_readl\>' --or \ -e '\<__raw_readq\>' --or \ -e '\<__raw_writeb\>' --or \ -e '\<__raw_writew\>' --or \ -e '\<__raw_writel\>' --or \ -e '\<__raw_writeq\>' --or \ -e '\<readb\>' --or \ -e '\<readw\>' --or \ -e '\<readl\>' --or \ -e '\<readq\>' --or \ -e '\<writeb\>' --or \ -e '\<writew\>' --or \ -e '\<writel\>' --or \ -e '\<writeq\>' --or \ -e '\<readb_relaxed\>' --or \ -e '\<readw_relaxed\>' --or \ -e '\<readl_relaxed\>' --or \ -e '\<readq_relaxed\>' --or \ -e '\<writeb_relaxed\>' --or \ -e '\<writew_relaxed\>' --or \ -e '\<writel_relaxed\>' --or \ -e '\<writeq_relaxed\>' --or \ -e '\<readsb\>' --or \ -e '\<readsw\>' --or \ -e '\<readsl\>' --or \ -e '\<readsq\>' --or \ -e '\<writesb\>' --or \ -e '\<writesw\>' --or \ -e '\<writesl\>' --or \ -e '\<writesq\>' --or \ -e '\<inb\>' --or \ -e '\<inw\>' --or \ -e '\<inl\>' --or \ -e '\<outb\>' --or \ -e '\<outw\>' --or \ -e '\<outl\>' --or \ -e '\<inb_p\>' --or \ -e '\<inw_p\>' --or \ -e '\<inl_p\>' --or \ -e '\<outb_p\>' --or \ -e '\<outw_p\>' --or \ -e '\<outl_p\>' --or \ -e '\<insb\>' --or \ -e '\<insw\>' --or \ -e '\<insl\>' --or \ -e '\<outsb\>' --or \ -e '\<outsw\>' --or \ -e '\<outsl\>' --or \ -e '\<insb_p\>' --or \ -e '\<insw_p\>' --or \ -e '\<insl_p\>' --or \ -e '\<outsb_p\>' --or \ -e '\<outsw_p\>' --or \ -e '\<outsl_p\>' --or \ -e '\<ioread8\>' --or \ -e '\<ioread16\>' --or \ -e '\<ioread32\>' --or \ -e '\<ioread64\>' --or \ -e '\<iowrite8\>' --or \ -e '\<iowrite16\>' --or \ -e '\<iowrite32\>' --or \ -e '\<iowrite64\>' --or \ -e '\<ioread16be\>' --or \ -e '\<ioread32be\>' --or \ -e '\<ioread64be\>' --or \ -e '\<iowrite16be\>' --or \ -e '\<iowrite32be\>' --or \ -e '\<iowrite64be\>' --or \ -e '\<ioread8_rep\>' --or \ -e '\<ioread16_rep\>' --or \ -e '\<ioread32_rep\>' --or \ -e '\<ioread64_rep\>' --or \ -e '\<iowrite8_rep\>' --or \ -e '\<iowrite16_rep\>' --or \ -e '\<iowrite32_rep\>' --or \ -e '\<iowrite64_rep\>' --or \ -e '\<__io_virt\>' --or \ -e '\<pci_iounmap\>' --or \ -e '\<virt_to_phys\>' --or \ -e '\<phys_to_virt\>' --or \ -e '\<ioremap_uc\>' --or \ -e '\<ioremap\>' --or \ -e '\<__ioremap\>' --or \ -e '\<iounmap\>' --or \ -e '\<ioremap\>' --or \ -e '\<ioremap_nocache\>' --or \ -e '\<ioremap_uc\>' --or \ -e '\<ioremap_wc\>' --or \ -e '\<ioremap_wc\>' --or \ -e '\<ioremap_wt\>' --or \ -e '\<ioport_map\>' --or \ -e '\<ioport_unmap\>' --or \ -e '\<ioport_map\>' --or \ -e '\<ioport_unmap\>' --or \ -e '\<xlate_dev_kmem_ptr\>' --or \ -e '\<xlate_dev_mem_ptr\>' --or \ -e '\<unxlate_dev_mem_ptr\>' --or \ -e '\<virt_to_bus\>' --or \ -e '\<bus_to_virt\>' --or \ -e '\<memset_io\>' --or \ -e '\<memcpy_fromio\>' --or \ -e '\<memcpy_toio\>' I also reordered a couple includes when they weren't alphabetical and removed clk.h from kona, replacing it with clk-provider.h because that driver doesn't use clk consumer APIs.

2019-04-04acpi: Create subtable parsing infrastructureKeith Busch1-1/+1
Parsing entries in an ACPI table had assumed a generic header structure. There is no standard ACPI header, though, so less common layouts with different field sizes required custom parsers to go through their subtable entry list. Create the infrastructure for adding different table types so parsing the entries array may be more reused for all ACPI system tables and the common code doesn't need to be duplicated.

2019-03-11mailbox: imx: keep MU irq working during suspend/resumeAnson Huang1-2/+2
During noirq suspend phase, mailbox MU irq will be masked but many drivers still need to communicate with system controller firmware via mailbox, if MU irq is masked, it will cause RPC timeout as below: [ 23.372103] imx-scu scu: RPC send msg timeout Setting MU irq to be wakeup source is NOT working as GIC driver does NOT have .irq_set_wake implemented, so to support suspend/resume, just make imx mailbox driver NOT suspend, since MU is always a wakeup source on i.MX platforms with system controller inside, and its power/clock is maintained by system controller, mailbox driver no need to manage them.

The Tegra HSP block supports 'shared mailboxes' that are simple 32-bit registers consisting of a FULL bit in MSB position and 31 bits of data. The hardware can be configured to trigger interrupts when a mailbox is empty or full. Add support for these shared mailboxes to the HSP driver. The initial use for the mailboxes is the Tegra Combined UART. For this purpose, we use interrupts to receive data, and spinning to wait for the transmit mailbox to be emptied to minimize unnecessary overhead.
