2011-04-25arm, hw_breakpoints: Fix racy access to ptrace breakpointsFrederic Weisbecker
While the tracer accesses ptrace breakpoints, the child task may concurrently exit due to a SIGKILL and thus release its breakpoints at the same time. We can then dereference some freed pointers. To fix this, hold a reference on the child breakpoints before manipulating them.

2011-04-25ARM: Davinci: Fix I2C build errorsRussell King - ARM Linux
Several Davinci platforms select the I2C EEPROM support, but don't select I2C support. This causes I2C EEPROM support to be built into the kernel, but I2C support may not be configured to be built in. This leads to linker errors due to missing I2C symbols. Arrange for I2C to be selected whenever EEPROM_AT24 is selected. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

2011-04-20OMAP3: PM: Do not rely on ROM code to restore CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLLEduardo Valentin
As per OMAP3 erratum (i671), ROM code adds extra latencies while restoring CM_AUTOIDLE_PLL register, if AUTO_PERIPH_DPLL is equal to 1. This patch stores 0's in scratchpad content area corresponding to AUTO_PERIPH_DPLL, to prevent ROM code to try to lock per DPLL, since it won't respect proper programing scheme. This register is then stored in prcm context. The saving and restore is now done by kernel side. Here follow the erratum description DESCRIPTION After OFF mode transition, among many restorations, the ROM Code restores the CM_AUTOIDLE_PLL register, and after that, it tries to relock the PER DPLL. In case the restoration data stored in scratchpad memory contains a field CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL = 1, then the way the ROM Code restores and locks the PER DPLL does not respect the PER DPLL programming scheme. In that case, the DPLL might not lock. Meanwhile, when trying to lock the PER DPLL, the ROM Code does not hang. Only extra latencies are introduced at wake-up. WORKAROUND When saving the context-restore structure in scratchpad memory, in order to respect the PER DPLL programming scheme, it is advised to store 0 in the CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL field of the saved structure. After wake-up, the application should store in CM_AUTOIDLE_PLL register the right desired value.

2011-04-20OMAP4: clock data: Change DSS clock aliasesTomi Valkeinen
DSS driver has used fck and ick clocks on OMAP2/3 to get DSS HW up and running, and also to get the pixel clock's source clock rate from the fck. On OMAP4 the clock data is set up in a different way, as there's no ick, dss_fck points to a fake clock which just affects DSS's MODULEMODE, and dss_dss_clk if the DSS_FCK. >From DSS driver's point of view the dss_fck sounds like an ick, and dss_dss_clk is the fck. While this is not entirely correct from HW point of view, especially for the ick, configuring the clock aliases that way makes DSS "just work" with OMAP4's clock setup. In the (hopefully near) future DSS driver will be reworked to use pm_runtime support which should clean up the clock code.

2011-04-12ARM: mxc: Correct data alignment in headsmp.S for CONFIG_THUMB2_KERNELDave Martin
Directives such as .long and .word do not magically cause the assembler location counter to become aligned in gas. As a result, using these directives in code sections can result in misaligned data words when building a Thumb-2 kernel (CONFIG_THUMB2_KERNEL). This is a Bad Thing, since the ABI permits the compiler to assume that fundamental types of word size or above are word- aligned when accessing them from C. If the data is not really word-aligned, this can cause impaired performance and stray alignment faults in some circumstances. In general, the following rules should be applied when using data word declaration directives inside code sections: * .quad and .double: .align 3 * .long, .word, .single, .float: .align (or .align 2) * .short: No explicit alignment required, since Thumb-2 instructions are always 2 or 4 bytes in size. immediately after an instruction.

2011-04-12ARM: mxs/clock-mx28: fix up name##_set_rateUwe Kleine-König
For the lcdif clock get_rate looks as follows: read div from HW_CLKCTRL_DIS_LCDIF.DIV return clk_get_rate(clk->parent) / div with clk->parent being ref_pix_clk on my system. ref_pix_clk's rate depends on HW_CLKCTRL_FRAC1.PIXFRAC. The set_rate function for lcdif does: parent_rate = clk_get_rate(clk->parent); based on that calculate frac and div such that parent_rate * 18 / frac / div is near the requested rate. HW_CLKCTRL_FRAC1.PIXFRAC is updated with frac HW_CLKCTRL_DIS_LCDIF.DIV is updated with div For this calculation to be correct parent_rate needs to be initialized not with the clock rate of lcdif's parent (i.e. ref_pix) but that of its grandparent (i.e. ref_pix' parent == pll0_clk). The obvious downside of this patch is that now set_rate(lcdif) changes its parent's rate, too. Still this is better than a wrong rate.
