Pull ARM SoC late updates from Arnd Bergmann: "Here are two branches that came relatively late during the linux-5.0 development cycle and have dependencies on the other branches: - On the TI OMAP platform, the CPSW Ethernet PHY mode selection driver is being replaced, this puts the final pieces in place - On the DaVinci platform, the interrupt handling code in arch/arm gets moved into a regular device driver in drivers/irqchip. Since they both had some time in linux-next after the 5.0-rc8 release, I'm sending them along with the other updates" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (38 commits) net: ethernet: ti: cpsw: deprecate cpsw-phy-sel driver ARM: davinci: remove intc related fields from davinci_soc_info irqchip: davinci-cp-intc: move the driver to drivers/irqchip ARM: davinci: cp-intc: remove redundant comments ARM: davinci: cp-intc: drop GPL license boilerplate ARM: davinci: cp-intc: use readl/writel_relaxed() ARM: davinci: cp-intc: unify error handling ARM: davinci: cp-intc: improve coding style ARM: davinci: cp-intc: request the memory region before remapping it ARM: davinci: cp-intc: use the new-style config structure ARM: davinci: cp-intc: convert all hex numbers to lowercase ARM: davinci: cp-intc: use a common prefix for all symbols ARM: davinci: cp-intc: add the new config structures for da8xx SoCs irqchip: davinci-cp-intc: add a new config structure ARM: davinci: cp-intc: add a wrapper around cp_intc_init() ARM: davinci: cp-intc: remove cp_intc.h irqchip: davinci-aintc: move the driver to drivers/irqchip ARM: davinci: aintc: remove unnecessary includes ARM: davinci: aintc: remove the timer-specific irq_set_handler() ARM: davinci: aintc: request memory region before remapping it ...

The aintc driver has now been cleaned up. Move it to drivers/irqchip where it belongs. There's no device-tree support for any dm* board so there's no IRQCHIP_OF_DECLARE() - there's only the exported init function called from machine code.

irqchip: Add driver for Cirrus Logic Madera codecs

2018-12-18T14:06:56Z

The Cirrus Logic Madera codecs (Cirrus Logic CS47L35/85/90/91 and WM1840) are highly complex devices containing up to 7 programmable DSPs and many other internal sources of interrupts plus a number of GPIOs that can be used as interrupt inputs. The large number (>150) of internal interrupt sources are managed by an on-board interrupt controller. This driver provides the handling for the interrupt controller. As the codec is accessed via regmap, we can make use of the generic IRQ functionality from regmap to do most of the work. Only around half of the possible interrupt source are currently of interest from the driver so only this subset is defined. Others can be added in future if needed. The KConfig options are not user-configurable because this driver is mandatory so is automatically included when the parent MFD driver is selected.

"LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines We'll continouslly improve csky subsystem in future" Arnd acks, and adds the following notes: "I did a thorough review of the ABI, which as usual mainly consists of spotting any files that don't use the asm-generic ABI itself, and having it changed to it matches exactly what we do on other new architectures. I also looked at every other patch and commented on maybe half of them where I saw something that did not quite seem right. Others have reviewed specific patches in greater depth. I'm sure that one could fine more of the minor details, but as long as they are not ABI relevant, they can be fixed later. The only patch that is part of the ABI and that nobody reviewed is the signal handling. This is one of the areas I never worked on in much detail. I did not see anything wrong with it, but I also don't know what the problems with the other architectures are here, and we seem to be hitting issues occasionally, and we never managed to generalize this enough for new architectures to have a trivial implementation. I was originally hoping that we could have the 64-bit time_t interfaces ready in time to completely drop the 32-bit ones, but that did not happen. We might still remove them in the next merge window depending on whether the libc upstream people prefer to keep them or not. One more general comment: I think this may well be the last new CPU architecture we ever add to the kernel. Both nds32 and c-sky are made by companies that also work on risc-v, and generally speaking risc-v seems to be killing off any of the minor licensable instruction set projects, just like ARM has mostly killed off the custom vendor-specific instruction sets already. If we add another architecture in the future, it may instead be something like the LLVM bitcode or WebAssembly, who knows?"

irqchip: add C-SKY APB bus interrupt controller

2018-10-25T16:54:30Z

The driver is for C-SKY APB bus interrupt controller. It's a simple interrupt controller which use pending reg to detect the irq and use enable/disable reg to mask/unmask interrupt sources. A lot of SOCs based on C-SKY CPU use the interrupt controller as root controller. Signed-off-by: Guo Ren Reviewed-by: Mark Rutland
