2011-05-21ARM: zImage: make sure the stack is 64-bit alignedNicolas Pitre
commit 3bd2cbb95543acf44fe123eb9f038de54e655eb4 upstream. With ARMv5+ and EABI, the compiler expects a 64-bit aligned stack so instructions like STRD and LDRD can be used. Without this, mysterious boot failures were seen semi randomly with the LZMA decompressor. While at it, let's align .bss as well.

2011-05-09ARM: 6891/1: prevent heap corruption in OABI semtimedopDan Rosenberg
commit 0f22072ab50cac7983f9660d33974b45184da4f9 upstream. When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not bound the nsops argument. A sufficiently large value will cause an integer overflow in allocation size, followed by copying too much data into the allocated buffer. Fix this by restricting nsops to SEMOPM. Untested.

2011-04-21ARM: 6864/1: hw_breakpoint: clear DBGVCR out of resetWill Deacon
commit e89c0d7090c54d7b11b9b091e495a1ae345dd3ff upstream. The DBGVCR, used for configuring vector catch debug events, is UNKNOWN out of reset on ARMv7. When enabling monitor mode, this must be zeroed to avoid UNPREDICTABLE behaviour. This patch adds the zeroing code to the debug reset path.

2011-03-27ASoC: mini2440: Fix uda134x codec problem.Marek Belisko
commit a110f4ef810ee29d810876df725f41d66629733e upstream. ASoC audio for mini2440 platform in current kenrel doesn't work. First problem is samsung_asoc_dma device is missing in initialization. Next problem is with codec. Codec is initialized but never probed because no platform_device exist for codec driver. It leads to errors during codec binding to asoc dai. Next problem was platform data which was passed from board to asoc main driver but not passed to codec when called codec_soc_probe(). Following patch should fix issues. But not sure if in correct way. Please review.

2011-03-23davinci: DM644x EVM: register MUSB device earlierSergei Shtylyov
commit 60d97a840175d3becb2e6de36537a5cdfc0ec3a9 upstream. The MUSB driver doesn't see its platform device on DM644x EVM board anymore since commit 73b089b052a69020b953312a624a6e1eb5b81fab (usb: musb: split davinci to its own platform_driver) because the new probe is called as subsys_initcall() now, and the device is registered later than that by the board code. Move the registration to davinci_evm_init() -- it's safe to do so because the MUSB core device still gets initialized as fs_initcall() -- which is late enough for the I2C GPIO expander (which controls VBUS) to be initialized.

This patch modifies the number of total GPIO lines for Bank F for Samsung S5P6440 and S5P6450 SoCs from 2 to 16. This is necessary as the GPIO lines from 0 to 13 are reserved and only lines 14 and 15 are used. As during initialization, the line number starts at 0, putting 2 does not solve the intended purpose.

This patch fix a bug in the register indexing for GPIOs numbers > 31 to get the relevant hardware registers of tnetv107x to control the GPIOs. In the structure tnetv107x_gpio_regs: struct tnetv107x_gpio_regs { u32 idver; u32 data_in[3]; u32 data_out[3]; u32 direction[3]; u32 enable[3]; }; The GPIO hardware register addresses of tnetv107x are stored. The chip implements 3 registers of each entity to serve 96 GPIOs, each register provides a subset of 32 GPIOs. The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit and gpio_reg_clear_bit. The bug implied the use of macros to access the relevant hardware register e.g. the driver code used the macro like this: 'gpio_reg_clear_bit(&reg->data_out, gpio)' But it has to be used like this: 'gpio_reg_clear_bit(reg->data_out, gpio)'. The different results are shown here: - &reg->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes) - reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes) Acked-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Hirosh Dabui <hirosh.dabui@snom.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

2011-02-26ARM: 6768/1: hw_breakpoint: ensure debug logic is powered up on v7 coresWill Deacon
ARMv7 allows the debug core logic to be powered down and provides the DBGPRSR register so that software can power-up and check the status of the logic. This patch ensures that the debug logic is powered up on ARMv7 cores before we attempt to access the extended debug registers.

2011-02-26ARM: 6767/1: ptrace: fix register indexing in GETHBPREGS requestWill Deacon
The GETHBPREGS ptrace request incorrectly maps its index argument onto the thread's saved debug state when the index != 0. This has not yet been seen from userspace because GDB (the only user of this request) only reads from register 0. This patch fixes the indexing.

2011-02-25omap4: prcm: Fix the CPUx clockdomain offsetsSantosh Shilimkar
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base. The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power domain control register Fix the same. The autogen scripts is fixed thanks to Benoit Cousson With the old value, the clockdomain code would access the *_PWRSTCTRL.POWERSTATE field when it thought it was accessing the *_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause system power management to behave incorrectly.

OMAP2+ kernels built without CONFIG_OMAP_32K_TIMER crash on boot after the 2.6.38 sched_clock changes: [ 0.000000] OMAP clockevent source: GPTIMER1 at 13000000 Hz [ 0.000000] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 0.000000] pgd = c0004000 [ 0.000000] [00000000] *pgd=00000000 [ 0.000000] Internal error: Oops: 80000005 [#1] SMP [ 0.000000] last sysfs file: [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 Not tainted (2.6.38-rc5-00057-g04aa67d #152) [ 0.000000] PC is at 0x0 [ 0.000000] LR is at sched_clock_poll+0x2c/0x3c Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and clocksource resolution about three orders of magnitude higher than with CONFIG_OMAP_32K_TIMER set. The tradeoff is that the lowest power consumption states are not available. Fix by calling init_sched_clock() from the GPTIMER clocksource init code.

2011-02-22OMAP2/3: clock: fix fint calculation for DPLL_FREQSELJohn Ogness
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction Feature", it is shown that the internal frequency is calculated by CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is already "N+1" since Linux is using the values to divide by. In the technical reference manual, "N" is referring to the divider's register value (0-127). During power management testing, it was observed that programming the wrong jitter correction value can cause the system to become unstable and eventually crash.
