No functional change, just a readability fix. The symbolic name of the shift value used in writing CM_AUTOIDLE_PLL_IVA2 referred values in the CM_CLKSTCTRL_IVA2 register. Fix this to use the AUTOIDLE fields. Signed-off-by:

The GPTIMER TLDR register does not need to be written if the GPTIMER is not in autoreload mode. This is the usual case for dynamic tick-enabled kernels. Simulation data indicate that skipping the read that occurs as part of the write should save at least 300-320 ns for each GPTIMER1 timer reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write posting is enabled.) Skipping the write itself probably won't have much impact since it should be posted on the OCP interconnect. Tested on 2430SDP and 3430SDP. Signed-off-by:

omap_dm_timer_write_reg() already waits for pending writes to complete, so the extra wait in omap_dm_timer_set_load() is superfluous. Signed-off-by:

Now that H3 is converted to use GPIO calls, get rid of the legacy gpio_expander_omap code ... it has no more users. One more needless divergence from mainline gone! Signed-off-by:

Update board-h3.c to use standard GPIO calls to set up the IRDA transceiver, not legacy OMAP-only gpioexpander code. Also, move the #include <.../ov9640.h>; the header is gone, there's currently no driver for that camera sensor. Signed-off-by:

Finish removing dependency of TWL driver stack on platform-specific IRQ definitions ... and remove the build dependency on OMAP. This lets the TWL4030 code be included in test builds for most platforms, and will make it easier for non-OMAP folk to update most of this code for new APIs etc. Signed-off-by:

Disable the TWL4030_PWRIRQ_PWRBTN symbol from the system headers; initialization of the power button handler still needs work, so an equivalent symbol is defined in its driver. Power IRQs now properly handle trigger specs from request_irq(); stop goofing with registers reserved to the IRQ infrastructure. Minor cleanup: switch several messages to pr_debug(). Signed-off-by:

Add init data for the LDO regulators used on Beagle boards: - VMMC1 is the main MMC1 power - VSIM powers MMC1 too: DAT4-DAT7 pins, for HSMMC cards - VDAC for S-Video output Those regulators need to be hooked up to the MMC1 and FB (?) devices through the regulator framework. Signed-off-by:

Initial code to create twl4030 voltage regulator devices, using the new regulator framework. Note that this now starts to care what name is used to declare the TWL chip: - TWL4030 is the "old" chip; newer ones have a bigger variety of VAUX2 voltages. - The tps65930 and tps65920 are cost-reduced catalog versions of the TWL5030 parts ... fewer regulators, no BCI, etc. (Rev C Beagles were anticipated to use '930 parts...) Board-specific regulator configuration should be provided, listing which regulators are used and their constraints (e.g. 1.8V only). Code that could ("should"?) leverage the regulator stuff includes twl4030 USB transceiver support and MMC glue, LCD support for the 3430SDP and Labrador boards, and S-Video output. Signed-off-by: -

There are already various drivers having bigger label than 10 bytes. Most of them fit well under 20 bytes but make column width exact so that oversized labels don't mess up output alignment. Signed-off-by:

During _omap3_noncore_dpll_lock(), if a DPLL has no active downstream clocks and DPLL autoidle is enabled, the DPLL may never lock, since it will enter autoidle immediately. To resolve this, disable DPLL autoidle while locking the DPLL, and unconditionally wait for the DPLL to lock. This fixes some bugs where the kernel would hang when returning from retention or return the wrong rate for the DPLL. This patch is a collaboration with Peter de Schrijver <peter.de-schrijver@nokia.com> and Kevin Hilman <khilman@deeprootsystems.com>. Signed-off-by:

The DPLL FREQSEL jitter correction bits are set based on a table in the 34xx TRM, Table 4-38, according to the DPLL's internal clock frequency "Fint." Several Fint frequency ranges are missing from this table. Previously, we allowed these Fint frequency ranges to be selected in the rate rounding code, but did not change the FREQSEL bits. Correspondence with the OMAP hardware team indicates that Fint values not in the table should not be used. So, prevent them from being selected during DPLL rate rounding. This removes warnings and also can prevent the chip from locking up. The first pass through the rate rounding code will update the DPLL max and min dividers appropriately, so later rate rounding passes will run faster than the first. Peter de Schrijver <peter.de-schrijver@nokia.com> put up with several test cycles of this patch - thanks Peter. Signed-off-by:

The previous DPLL rate rounding algorithm counted the divider (N) down from the maximum to 1. Since we currently use a broad DPLL rate tolerance, and lower N values are more power-efficient, we can often bypass several iterations through the loop by counting N upwards from 1.

The I2C controller clears its OCP_SYSCONFIG register after an OCP soft reset. Reprogram OCP_SYSCONFIG for maximum power savings on rev3.6 controllers and beyond. On 2430, this involves setting the module AUTOIDLE bit. On 3430, this includes module AUTOIDLE, wakeup enable, slave smart-idle, and considers only the module functional clock state for idle-ack. Boot-tested on 2430SDP and 3430SDP. Signed-off-by:

i2c-omap discriminates only between "revision 1" or "greater than revision 1." A following patch introduces code that must also discriminate between rev2.x, rev3.6, and rev3.12 controllers. Support this by storing the full revision data from the I2C_REV register, rather than just a single bit. The revision definitions may need to be extended for other ES levels that aren't currently available here. rev3.6 is what's present on the 2430SDP here (unknown ES revision); rev3.12 is used on the 3430ES2 here.
