The code currently panics if PCI is enabled but the SoC has no PCI bus. This check is superfluous as the driver only loads if enabled in the devicetree. Signed-off-by:

MT7688 has several uarts that can be used for console. There are several boards in the wild, that use ttyS1 or ttyS2. This patch applies a simply autodetection routine to figure out which ttyS the bootloader used as console. The uarts come up in 6 bit mode by default. The bootloader will have set 8 bit mode on the console. Find that 8bit tty and use it. Signed-off-by:

If the USB HCD is running and the cpu is scaled too low, then the USB stops working. Increase the idle speed of the core to fix this if the kernel is built with USB support. The "magic" values are taken from the Ralink SDK Kernel. Signed-off-by:

request_mem_region() returns a pointer and not an integer with an error value. A check for "< 0" on a pointer will cause problems, replace it with not null checks instead. This was found with sparse. Signed-off-by:

When the SoC starts up most of the devices should be deactivated by the PMU, they should be activated when they get used by their drivers. Some devices should not get deactivate at startup like the serial, register them in a special way. Signed-off-by:

The PMU register are accessed in a non atomic way and they could be accessed by different threads simultaneously, which could cause problems this patch adds locking around the PMU registers. In addition we now also wait till the PMU is actually deactivated.

This drops another symbol dependency between setup.c and sprom.c which will allow us to make SPROM code a separated module (and share it with ARM). Patch tested on Linksys WRT300N V1. Signed-off-by:

To support (extract) SPROM on Broadcom ARM devices we should separate SPROM code and make it a separated module. We won't want to export bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard fallback function and then modify ssb to use it. Signed-off-by:

This adds a basic implementation of clk_round_rate() The clk_round_rate() function is called by multiple drivers and subsystems now and the lantiq clk driver is supposed to export this, but doesn't do so, this causes linking problems like this one: ERROR: "clk_round_rate" [drivers/media/v4l2-core/videodev.ko] undefined!

for_each_child_of_node performs an of_node_get on each iteration, so no of_node_get is needed on breaking out of the loop when the device_node structure is saved in another variable. A simplified semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root; local idexpression child; @@ for_each_child_of_node(root, child) { ... * of_node_get(child) ... break; } // </smpl> Signed-off-by:

Add user-mode implementations of gettimeofday() and clock_gettime() to the VDSO. This is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below the VDSO data page. When a supported clocksource is not in use, the VDSO functions will return -ENOSYS, which causes libc to fall back on the standard syscall path. When support for neither of these clocksources is compiled into the kernel at all, the VDSO still provides clock_gettime(), as the coarse realtime/monotonic clocks can still be implemented. However, gettimeofday() is not provided in this case as nothing can be done without a suitable clocksource. This causes the symbol lookup to fail in libc and it will then always use the standard syscall path. This patch includes a workaround for a bug in QEMU which results in RDHWR on the CP0 count register always returning a constant (incorrect) value. A fix for this has been submitted, and the workaround can be removed after the fix has been in stable releases for a reasonable amount of time. A simple performance test which calls gettimeofday() 1000 times in a loop and calculates the average execution time gives the following results on a Malta + I6400 (running at 20MHz): - Syscall: ~31000 ns - VDSO (GIC): ~15000 ns - VDSO (CP0): ~9500 ns [markos.chandras@imgtec.com: - Minor code re-arrangements in order for mappings to be made in the order they appear to the process' address space. - Move do_{monotonic, realtime} outside of the MIPS_CLOCK_VSYSCALL ifdef - Use gic_get_usm_range so we can do the GIC mapping in the arch/mips/kernel/vdso instead of the GIC irqchip driver] Signed-off-by:Alex Smith <alex.smith@imgtec.com> Signed-off-by:

The GIC provides a "user-mode visible" section containing a mirror of the counter registers which can be mapped into user memory. This will be used by the VDSO time function implementations, so provide a function to map it in. When the GIC is not enabled in Kconfig a dummy inline version of this function is provided, along with "#define gic_present 0", so that we don't have to litter the VDSO code with ifdefs. [markos.chandras@imgtec.com: - Move mapping code to arch/mips/kernel/vdso.c and use a resource type to get the GIC usermode information - Avoid renaming function arguments and use __gic_base_addr to hold the base GIC address prior to ioremap.] [ralf@linux-mips.org: Fix up gic_get_usm_range() to compile and make inline again.] Signed-off-by:Marc Zyngier <marc.zyngier@arm.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Jason Cooper <jason@lakedaemon.net> Cc: Marc Zyngier <marc.zyngier@arm.com> Cc: Alex Smith <alex.smith@imgtec.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-kernel@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/11281/Signed-off-by:
