      arm: mach-omap2: smartreflex: fix another memory leak · 865212ab
      由 Aaro Koskinen 提交于 
      Temporary strings with volt_* file names should be released after the
debugfs entries are created. While at it, also simplify the string
allocation, and use just snprintf() to create the name.

The patch eliminates kmemleak reports with the following stack trace
(multiple objects depending on HW):

      davinci: tnetv107x: fix register indexing for GPIOs numbers > 31 · c284d9fa
      由 Hirosh Dabui 提交于 
      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)

      由 Rajashekhara, Sudhakar 提交于 
      After the multi-component commit f0fba2ad (ASoC: multi-component - ASoC
Multi-Component Support) for ASoC, we need to register the platform
device for davinci-pcm-audio.

This patch and patch at [1] are required for audio to work on
DA850/OMAP-L138.

      OMAP2+: clocksource: fix crash on boot when !CONFIG_OMAP_32K_TIMER · cbc94380
      由 Paul Walmsley 提交于 
      
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] CPU: 0    Not tainted  (2.6.38-rc5-00057-g04aa67de #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.

      OMAP2/3: clock: fix fint calculation for DPLL_FREQSEL · ea68c00e
      由 John Ogness 提交于 
      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.
