2009-11-02MIPS: AR7: register watchdog device only if enabled in hw configurationFlorian Fainelli2-1/+11
This patch checks if the watchdog enable bit is set in the DCL register meaning that the hardware watchdog actually works and if so, register the ar7_wdt platform_device. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-11-02MIPS: BCM63xx: Prepare for watchdog supportFlorian Fainelli2-1/+38
This patch prepares the board code to register a bcm63xx_wdt platform_device that we are going to use in a subsequent patch. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-11-02MIPS: BCM63xx: Make bcm63xx_uart_register an initfuncFlorian Fainelli3-10/+1
This patch removes the calls to bcm63xx_uart_register in board_bcm963xx.c and make bcm63xx_uart_register an initfunc. Allows us to remove bcm63xx_dev_uart.h which was there to make checkpatch.pl happy. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This patch fixes a lockup on BCM6345 where setting the PLL soft reset bit will also lock the other blocks including UART. Instead of setting only the PLL soft reset bit in the software reset register, set this bit but do not touch the others.

2009-11-02MIPS: Don't write ones to reserved entryhi bits.Ralf Baechle1-5/+5
We've silently been relying on the hardware chopping off excess, reserved ASID bits for no better reason that it saving an instruction. Because we already have: #define cpu_asid(cpu, mm) (cpu_context((cpu), (mm)) & ASID_MASK) in <asm/mmu_context.h>. We can use a cleanup to avoid writing non-zero bits into the reserved entryhi bits. This avoid triggering some debugging assertion in the Cavium simulator. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-10-31NOMMU: Don't pass NULL pointers to fput() in do_mmap_pgoff()David Howells1-2/+4
Don't pass NULL pointers to fput() in the error handling paths of the NOMMU do_mmap_pgoff() as it can't handle it. The following can be used as a test program: int main() { static long long a[1024 * 1024 * 20] = { 0 }; return a;} Without the patch, the code oopses in atomic_long_dec_and_test() as called by fput() after the kernel complains that it can't allocate that big a chunk of memory. With the patch, the kernel just complains about the allocation size and then the program segfaults during execve() as execve() can't complete the allocation of all the new ELF program segments.

2009-10-30Driver core: allow certain drivers prohibit bind/unbind via sysfsDmitry Torokhov3-8/+19
Platform drivers registered via platform_driver_probe() can be bound to devices only once, upon registration, because discard their probe() routines to save memory. Unbinding the driver through sysfs 'unbind' leaves the device stranded and confuses users so let's not create bind and unbind attributes for such drivers.

2009-10-30Driver core: fix driver_register() return valueStas Sergeev1-1/+1
In this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c the check was added for another driver to already claim the same device on the same bus. But the returned error code was wrong: to modprobe, the -EEXIST means that _this_ driver is already installed. It therefore doesn't produce the needed error message when _another_ driver is trying to register for the same device. Returning -EBUSY fixes the problem.

2009-10-30Staging: Panel: prevent driver from calling misc_deregister twice on same ressourcePeter Huewe1-3/+10
This patch prevents the driver from calling misc_deregister twice on the same ressouce when unloading the driver. Unloading the driver without this patch results in a Kernel BUG like this: Panel driver version 0.9.5 registered on parport0 (io=0x378). BUG: unable to handle kernel paging request at 0000000000100108 IP: [<ffffffff803c02ee>] misc_deregister+0x2d/0x90 PGD 6caff067 PUD 762b7067 PMD 0 Oops: 0002 [#1] PREEMPT SMP last sysfs file: /sys/devices/platform/w83627hf.656/in8_input ... This patch fixes this issue, although maybe not in the best way possible :) linux version v2.6.32-rc1 - linus git tree, Di 29.
