2013-03-12ARM: w1-gpio: fix erroneous gpio requestsJohan Hovold
Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add ext_pullup_enable pin in platform data") which added a gpio entry to the platform data, but did not add the required initialisers to the board files using it. Consequently, the driver would request gpio 0 at probe, which could break other uses of the corresponding pin. On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for instance, breaks SPI0 on at91sam9g20.

2013-03-11xen: arm: mandate EABI and use generic atomic operations.Ian Campbell
Rob Herring has observed that c81611c4e96f "xen: event channel arrays are xen_ulong_t and not unsigned long" introduced a compile failure when building without CONFIG_AEABI: /tmp/ccJaIZOW.s: Assembler messages: /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]' Will Deacon pointed out that this is because OABI does not require even base registers for 64-bit values. We can avoid this by simply using the existing atomic64_xchg operation and the same containerof trick as used by the cmpxchg macros. However since this code is used on memory which is shared with the hypervisor we require proper atomic instructions and cannot use the generic atomic64 callbacks (which are based on spinlocks), therefore add a dependency on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much downside to this. While thinking about this we also observed that OABI has different struct alignment requirements to EABI, which is a problem for hypercall argument structs which are shared with the hypervisor and which must be in EABI layout. Since I don't expect people to want to run OABI kernels on Xen depend on CONFIG_AEABI explicitly too (although it also happens to be enforced by the !GENERIC_ATOMIC64 requirement too).

2013-03-08arm: plat-orion: fix address decoding when > 4GB is usedThomas Petazzoni
During the system initialization, the orion_setup_cpu_mbus_target() function reads the SDRAM address decoding registers to find out how many chip-selects of SDRAM have been enabled, and builds a small array with one entry per chip-select. This array is then used by device drivers (XOR, Ethernet, etc.) to configure their own address decoding windows to the SDRAM. However, devices can only access the first 32 bits of the physical memory. Even though LPAE is not supported for now, some Marvell boards are now showing up with 8 GB of RAM, configured using two SDRAM address decoding windows: the first covering the first 4 GB, the second covering the last 4 GB. The array built by orion_setup_cpu_mbus_target() has therefore two entries, and device drivers try to set up two address decoding windows to the SDRAM. However, in the device registers for the address decoding, the base address is only 32 bits, so those two windows overlap each other, and the devices do not work at all. This patch makes sure that the array built by orion_setup_cpu_mbus_target() only contains the SDRAM decoding windows that correspond to the first 4 GB of the memory. To do that, it ignores the SDRAM decoding windows for which the 4 low-order bits are not zero (the 4 low-order bits of the base register are used to store bits 32:35 of the base address, so they actually indicate whether the base address is above 4 GB). This patch allows the newly introduced armada-xp-gp board to properly operate when it is mounted with more than 4 GB of RAM. Without that, all devices doing DMA (for example XOR and Ethernet) do not work at all.

2013-03-08arm: mvebu: Reduce reg-io-width with UARTsHeikki Krogerus
Setting the reg-io-width to 1 byte represents more accurate description of the HW. This will fix an issue where UART driver causes kernel panic during bootup. Gregory CLEMENT traced the issue to autoconfig() in 8250.c, where the existence of FIFO is checked from UART_IIR register. The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.

2013-03-08ARM: kirkwood: fix to retain gbe MAC addresses for DT kernelsSebastian Hesselbarth
The ethernet controller used on kirkwood looses its MAC address register contents when the corresponding clock is gated. As soon as mv643xx_eth is built as module, the clock gets gated and when loading the module, the MAC address is gone. Proper DT support for the mv643xx_eth driver is expected soon, so we add a workaround to always enable ge0/ge1 clocks on kirkwood. This workaround is also already used on non-DT kirkwood kernels.

2013-03-08ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper
When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.

2013-03-07ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) ↵Ivan Djelic
optimizations Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on assumptions about the implementation of memset and similar functions. The current ARM optimized memset code does not return the value of its first argument, as is usually expected from standard implementations. For instance in the following function: void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter) { memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter)); waiter->magic = waiter; INIT_LIST_HEAD(&waiter->list); } compiled as: 800554d0 <debug_mutex_lock_common>: 800554d0: e92d4008 push {r3, lr} 800554d4: e1a00001 mov r0, r1 800554d8: e3a02010 mov r2, #16 ; 0x10 800554dc: e3a01011 mov r1, #17 ; 0x11 800554e0: eb04426e bl 80165ea0 <memset> 800554e4: e1a03000 mov r3, r0 800554e8: e583000c str r0, [r3, #12] 800554ec: e5830000 str r0, [r3] 800554f0: e5830004 str r0, [r3, #4] 800554f4: e8bd8008 pop {r3, pc} GCC assumes memset returns the value of pointer 'waiter' in register r0; causing register/memory corruptions. This patch fixes the return value of the assembly version of memset. It adds a 'mov' instruction and merges an additional load+store into existing load/store instructions. For ease of review, here is a breakdown of the patch into 4 simple steps: Step 1 ====== Perform the following substitutions: ip -> r8, then r0 -> ip, and insert 'mov ip, r0' as the first statement of the function. At this point, we have a memset() implementation returning the proper result, but corrupting r8 on some paths (the ones that were using ip). Step 2 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 1: save r8: - str lr, [sp, #-4]! + stmfd sp!, {r8, lr} and restore r8 on both exit paths: - ldmeqfd sp!, {pc} @ Now <64 bytes to go. + ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go. (...) tst r2, #16 stmneia ip!, {r1, r3, r8, lr} - ldr lr, [sp], #4 + ldmfd sp!, {r8, lr} Step 3 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 0: save r8: - stmfd sp!, {r4-r7, lr} + stmfd sp!, {r4-r8, lr} and restore r8 on both exit paths: bgt 3b - ldmeqfd sp!, {r4-r7, pc} + ldmeqfd sp!, {r4-r8, pc} (...) tst r2, #16 stmneia ip!, {r4-r7} - ldmfd sp!, {r4-r7, lr} + ldmfd sp!, {r4-r8, lr} Step 4 ====== Rewrite register list "r4-r7, r8" as "r4-r8".

2013-03-06ARM: 7666/1: decompressor: add -mno-single-pic-base for building the ↵Jonathan Austin
decompressor Before jumping to (position independent) C-code from the decompressor's assembler world we set-up the C environment. This setup currently does not set r9, which for arm-none-uclinux-uclibceabi toolchains is by default expected to be the PIC offset base register (IE should point to the beginning of the GOT). Currently, therefore, in order to build working kernels that use the decompressor it is necessary to use an arm-linux-gnueabi toolchain, or similar. uClinux toolchains cause a prefetch abort to occur at the beginning of the decompress_kernel function. This patch allows uClinux toolchains to build bootable zImages by forcing the -mno-single-pic-base option, which ensures that the location of the GOT is re-derived each time it is required, and r9 becomes free for use as a general purpose register.

2013-03-04ARM: dts: remove generated .dtb files on cleanNishanth Menon
commit 5f300acd8ae9f3d4585154370012ffc5c665330f (ARM: 7152/1: distclean: Remove generated .dtb files) ensured that dtbs were cleaned up when they were in arch/arm/boot. However, with the following commit: commit 499cd8298628eeabf0eb5eb6525d4faa0eec80d8 (ARM: dt: change .dtb build rules to build in dts directory) make clean now leaves dtbs in arch/arm/boot/dts/ untouched. Include dts directory so that clean-files rule from arch/arm/boot/dts/Makefile is invoked when make clean is done.

2013-03-04ARM: bcm2835: fix I2C module clock rateStephen Warren
BCM2835-ARM-Peripherals.pdf states that the I2C module's input clock is nominally 150MHz, and that value is currently reflected in bcm2835.dtsi. However, practical measurements show that the rate is actually 250MHz, and this agrees with various downstream kernels. Switch the I2C clock's frequency to 250MHz so that the generated bus clock rate is accurate. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Olof Johansson <olof@lixom.net>

2013-03-04ARM: OMAP2+: mux: correct wrong error messagesRuslan Bilovol
This is needed because the omap_mux_get_by_name() function calls the _omap_mux_get_by_name subfunction for each mux partition until needed mux is not found. As a result, we get messages like "Could not find signal XXX" for each partition where this mux name does not exist. This patch fixes wrong error message in the _omap_mux_get_by_name() function moving it to the omap_mux_get_by_name() one and as result reduces noise in the kernel log. My kernel log without this patch: [...] [ 0.221801] omap_mux_init: Add partition: #2: wkup, flags: 3 [ 0.222045] _omap_mux_get_by_name: Could not find signal fref_clk0_out.sys_drm_msecure [ 0.222137] _omap_mux_get_by_name: Could not find signal sys_nirq [ 0.222167] _omap_mux_get_by_name: Could not find signal sys_nirq [ 0.225006] _omap_mux_get_by_name: Could not find signal uart1_rx.uart1_rx [ 0.225006] _omap_mux_get_by_name: Could not find signal uart1_rx.uart1_rx [ 0.270111] _omap_mux_get_by_name: Could not find signal fref_clk4_out.fref_clk4_out [ 0.273406] twl: not initialized [...] My kernel log with this patch: [...] [ 0.221771] omap_mux_init: Add partition: #2: wkup, flags: 3 [ 0.222106] omap_mux_get_by_name: Could not find signal sys_nirq [ 0.224945] omap_mux_get_by_name: Could not find signal uart1_rx.uart1_rx [ 0.274536] twl: not initialized [...] Signed-off-by: Ruslan Bilovol <ruslan.bilovol@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2013-03-04ARM: OMAP2+: Fix broken gpmc supportJon Hunter
Commit 6797b4fe (ARM: OMAP2+: Prevent potential crash if GPMC probe fails) added code to ensure that GPMC chip-selects could not be requested until the device probe was successful. The chip-selects should have been unreserved at the end of the probe function, but the code to unreserve them appears to have ended up in the gpmc_calc_timings() function and hence, this is causing problems requesting chip-selects. Fix this merge error by unreserving the chip-selects at the end of the probe, but before we call the gpmc child probe functions (for device-tree) which request a chip-select.
