2016-12-11MIPS: Lantiq: Fix mask of GPE frequencyHauke Mehrtens1-1/+1
The hardware documentation says bit 11:10 are used for the GPE frequency selection. Fix the mask in the define to match these bits.

2016-10-04MIPS: Lantiq: Make xrx200_phy_fw explicitly non-modularPaul Gortmaker1-8/+4
The Kconfig currently controlling compilation of this code is: arch/mips/lantiq/Kconfig:config XRX200_PHY_FW arch/mips/lantiq/Kconfig: bool "XRX200 PHY firmware loader" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. We don't replace module.h with init.h since the file doesn't need that.

2016-08-02MIPS: store the appended dtb address in a variableJonas Gorski1-2/+2
Instead of rewriting the arguments to match the UHI spec, store the address of a appended or UHI supplied dtb in fw_supplied_dtb. That way the original bootloader arugments are kept intact while still making the use of an appended dtb invisible for mach code. Mach code can still find out if it is an appended dtb by comparing fw_arg1 with fw_supplied_dtb.

2016-07-24MIPS: Lantiq: Register IRQ handler for virtual IRQ numberHauke Mehrtens1-1/+1
We used the hardware IRQ number to register the IRQ handler and not the virtual one. This probably caused some problems because the hardware IRQ numbers are only unique for each IRQ controller and not in the system. The virtual IRQ number is managed by Linux and unique in the system. This was probably the reason there was a gab of 8 IRQ numbers added before the numbers used for the lantiq IRQ controller. With the current setup the hardware and the virtual IRQ numbers are the same.

2016-07-24MIPS: Lantiq: Use the real EXIN countJohn Crispin1-3/+3
We runtime load the available external interrupts into an array and store the number inside exin_avail. Some of the code however uses MAX_EIU for looping over the array which may partially be 0. This is a cosmetic fix as the existing code works as is. It is just nicer to only loop over the array elements that were actually populated during probe.

2015-08-03MIPS: SMP: Don't increment irq_count multiple times for call function IPIsAlex Smith1-1/+1
The majority of SMP platforms handle their IPIs through do_IRQ() which calls irq_{enter/exit}(). When a call function IPI is received, smp_call_function_interrupt() is called which also calls irq_{enter,exit}(), meaning irq_count is raised twice. When tick broadcasting is used (which is implemented via a call function IPI), this incorrectly causes all CPU idle time on the core receiving broadcast ticks to be accounted as time spent servicing IRQs, as account_process_tick() will account as such if irq_count is greater than 1. This results in 100% CPU usage being reported on a core which receives its ticks via broadcast. This patch removes the SMP smp_call_function_interrupt() wrapper which calls irq_{enter,exit}(). Platforms which handle their IPIs through do_IRQ() now call generic_smp_call_function_interrupt() directly to avoid incrementing irq_count a second time. Platforms which don't (loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt() wrapped in irq_{enter,exit}().

The voice and dsl drivers need to know which SoC we are running on. Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com> Patchwork: http://patchwork.linux-mips.org/patch/8046/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2014-11-24MIPS: lantiq: add support for xrx200 firmware depending on soc typeJohn Crispin1-1/+22
VR9 needs different firmware files for the various phy/soc revisions. Some boards are ship with older and newer SoC revisions. To be able to boot a single image on all versions we need to define both firmware files inside the devicetree.

2014-11-24MIPS: lantiq: handle vmmc memory reservationJohn Crispin2-0/+71
The Lantiq SoCs have a 2nd mips core called "voice mips macro core (vmmc)" which is used to run the voice firmware. This driver allows us to register a chunk of memory that the voice driver can later use for the 2nd core.
