2014-02-04MIPS: Alchemy: Fix DB1100 GPIO registrationManuel Lauss1-5/+2
With CONFIG_GPIOLIB=y gpios need to be requested before they can be modified. Request the SD carddetect pins, and drop the SPI direction setup, as the driver does that for us anyway. This gets rid of a lot of WARN_ON()s triggered by GPIO core, and restores functionality of the touschreen controller.

Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.

The second patch an overlooked and unused chunk of mips code that that fails to build after the first patch. The code hasn't been in linux-next for long (as I was out of it and could not sheppared the cold properly) but the patch has been around for a long time just waiting for the day when I had finished the uid/gid conversions. Putting the code in linux-next did find the compile failure on mips so I took the time to get that fix reviewed and included.

2014-01-24MIPS: KVM: remove shadow_tlb codeJames Hogan3-138/+0
The kvm_mips_init_shadow_tlb() function is called from kvm_arch_vcpu_init() and initialises entries 0 to current_cpu_data.tlbsize-1 of the virtual cpu's shadow_tlb[64] array. However newer cores with FTLBs can have a tlbsize > 64, for example the ProAptiv I'm testing on has a total tlbsize of 576. This causes kvm_mips_init_shadow_tlb() to overflow the shadow_tlb[64] array and overwrite the comparecount_timer among other things, causing a lock up when starting a KVM guest. Aside from kvm_mips_init_shadow_tlb() which only initialises it, the shadow_tlb[64] array is only actually used by the following functions: - kvm_shadow_tlb_put() & kvm_shadow_tlb_load() These are never called. The only call sites are #if 0'd out. - kvm_mips_dump_shadow_tlbs() This is never called. It was originally added for trap & emulate, but turned out to be unnecessary so it was disabled. So instead of fixing the shadow_tlb initialisation code, lets just remove the shadow_tlb[64] array and the above functions entirely. The only functional change here is the removal of broken shadow_tlb initialisation. The rest just deletes dead code.

2014-01-24MIPS: KVM: use common EHINV aware UNIQUE_ENTRYHIJames Hogan1-3/+1
When KVM is enabled and TLB invalidation is supported, kvm_mips_flush_host_tlb() can cause a machine check exception due to multiple matching TLB entries. This can occur on shutdown even when KVM hasn't been actively used. Commit adb78de9eae8 (MIPS: mm: Move UNIQUE_ENTRYHI macro to a header file) created a common UNIQUE_ENTRYHI in asm/tlb.h but it didn't update the copy of UNIQUE_ENTRYHI in kvm_tlb.c to use it. Commit 36b175451399 (MIPS: tlb: Set the EHINV bit for TLBINVF cores when invalidating the TLB) later added TLB invalidation (EHINV) support to the common UNIQUE_ENTRYHI. Therefore make kvm_tlb.c use the EHINV aware UNIQUE_ENTRYHI implementation in asm/tlb.h too.

The early serial code is not needed because we already have early printk support provided by common/earlycons.c This change also fixes the following build error that occurs when CONFIG_SERIAL_8250 is not configured for Netlogic XLR boards: arch/mips/built-in.o: In function `nlm_early_serial_setup': setup.c:(.init.text+0x274): undefined reference to `early_serial_setup' make: *** [vmlinux] Error 1 Reported-by: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/6083/
2014-01-24MIPS: Netlogic: Add default DTB for XLP9XX SoCJayachandran C4-1/+92
Add a default device tree fie for XLP9XX boards, and add code to use this device tree if no DTB is passed to the kernel. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/6287/
2014-01-24MIPS: Netlogic: XLP9XX PIC OF supportJayachandran C1-6/+31
Support for adding legacy IRQ domain for XLP9XX. The node id of the PIC has to be calulated differently for XLP9XX. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/6286/
2014-01-24MIPS: Netlogic: XLP9XX USB supportGanesan Ramalingam4-13/+84
XLP9XX has a USB 3.0 controller on-chip with 2 xHCI ports. The USB block is similar to the one on XLP2XX, so update usb-init-xlp2.c to handle XLP9XX as well.

2014-01-24MIPS: PCI: Netlogic XLP9XX supportJayachandran C4-23/+90
Add PCI support for Netlogic XLP9XX. The PCI registers and SoC bus numbers have changed in XLP9XX. Also skip a few (bus,dev,fn) combinations which have issues when read.

2014-01-24MIPS: Netlogic: Add cpu to node mapping for XLP9XXJayachandran C8-14/+33
XLP9XX has 20 cores per node, opposed to 8 on earlier XLP8XX. Update code that calculates node id from cpu id to handle this. Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: John Crispin <blogic@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/6283/

2014-01-24MIPS: Netlogic: SYS block updates of XLP9XXJayachandran C5-26/+84
Add the SYS block registers for XLP9XX, most of them have changed. The wakeup sequence has been updated to set the coherent mode from the main thread rather than the woken up thread.

2014-01-24MIPS: Netlogic: update iomap.h for XLP9XXJayachandran C3-2/+48
Most IO block offsets have changed in XLP9XX. Update iomap.h to add the new addresses of different SoC blocks like PIC, SYS, UART etc. that are needed by the base code. On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus corresponding to the node. Update iomap code to reflect this.
