Migrate to smsc911x ethernet driver instead of smc911x driver. The smsc911x ethernet driver supports NAPI and performs better under heavy traffic. With the smc911x driver we were witnessing very high iowait time for high IO load over NFS. Signed-off-by:

Initialize vmmc and vmmc_aux regulators Note that the omap3evm_twldata.vmmc1 and omap3evm_twldata.vsim are set in omap3_evm_i2c_init() to avoid a merge conflict with the MFD tree. These will be initialized in omap3evm_i2c_boardinfo as a fix later on. Signed-off-by:

Added runtime programming for the differences in EHCI interface between OMAP3EVM revisions (Rev >= E) and (Rev < E). Changes: - EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E uses GPIO pin 135. - Rev >= E uses EHCI Vbus enable GPIO22 line. - Rev >= E uses GPIO61 to select EHCI port either on main board or on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have EHCI port on main board. - Currently GPIO61 it programmed to enable EHCI port on main board only. Signed-off-by:Ajay Kumar Gupta <ajay.gupta@ti.com>

The mainline merge of the 3430SDP support (commit 6fdc29e2) seems to have messed up the 3430 defconfig completely. Update the defconfig using a known good version (SDP defconfig from v2.6.26-omap2 and current beagle defconfig) as reference. The image size is now 1.9 MB down from 2.4 MB earlier, and the number of modules is 8, down from 203. Build time also scales proportionally. Other support (OneNAND, etc) can be enabled as needed. Note that this patch intentionally does not update CONFIG_FB related options to avoid merge conflicts with the pending omap_dss2 patches. Signed-off-by:

This patch disables a GPIO module when all pins of a GPIO module are inactive (clock gating forced at module level) and enables the module when any gpio in the module is requested. The module is enabled only when "mod_usage" indicates that no GPIO in that module is currently active and the GPIO being requested is the 1st one to be active in that module. Each module would be disabled in omap_gpio_free() API when all GPIOs in a particular module becomes inactive. The module is re-enabled in omap_gpio_request() API when a GPIO is requested from the module that was previously disabled. Since individual GPIO's bookkeeping is added in this patch via "mod_usage", the same is used in omap_set_gpio_debounce() & omap_set_gpio_debounce_time() APIs to ensure that the gpio being used is actually "requested" prior to being used (Nishant Menon's <nm@ti.comSuggestion) GPIO module level details are specific to hardware and hence introducing this patch in low level layer (plat-omap/gpio.c) Signed-off-by:

map_iovm_area is only called from a context where its second argument is known not to be NULL, so drop the unnecessary test. If new could be NULL, the initialization of da should be moved below the test. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != \(x = E\|&x\) * x == NULL // </smpl> Signed-off-by:

All of the OMAP3 IVA physical address macros in plat-omap/include/plat/omap34xx.h are wrong[1]: OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear to be accessible from the L3 interconnect, and in any case is definitely not at 0x40000000; the latter address appears to be the internal IVA physical address base for the OMAP2420's interrupt control[2]. OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to the IVA starts at 0x5c000000, not 0x58000000. OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not in the L3 IVA address space. OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from the OMAP2420 days and no longer applies to OMAP3. OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000. Nothing that uses these can possibly be working, so drop them. When future code needs these, correct versions can be added in. 1. OMAP34xx Multimedia Device Silicon Revision 3.1.x Rev. W, Table 2-8: "L3 Interconnect View of the IVA2.2 Subsystem Memory Space." p. 229. 2. OMAP2420 Multimedia Processor Silicon Revision 2.1.1, 2.2 (Rev.

OMAP3630 is the latest in the family of OMAP3 devices and among the changes it introduces are: New OPP levels for new voltage and frequency levels. a bunch of Bug fixes to various modules feature additions, notably with ISP, sDMA etc. Details about the chip is available here: http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606 Strategy used: Strategy to introduce this device into Linux was discussed here: Ref: http://marc.info/?t=125343303400003&r=1&w=2 Two approaches were available: a) Consider 3630 generation of devices as a new family of silicon b) Consider 3630 as an offshoot of 3430 family of devices As a common consensus, (b) seems to be more valid for 3630 as: * There are changes which are easily handled by using "FEATURES" infrastructure. For details how to do this, see thread: http://marc.info/?t=125050998500001&r=1&w=2 * Most of existing 34xx infrastructure can be reused(almost 90%+) - so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx()) all over the place - lesser chance of bugs due to reuse of proven code flow - 36xx specific handling can still be done where required within the existing infrastructure NOTE: * If additional 34xx series are added, OMAP3430_REV_ESXXXX can be added on top of the existing 3630 ones are renumbered This patch was tested on SDP3430, boot tested on 3630 platform using 3430sdp defconfig Signed-off-by:

The l3_ocpi_ck clock is needed on omap7xx processors for USB. Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for the usb_dc_ck on omap7xx, which is a different bit than that of the omap16xx-defined clock of the same name. I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as dc_clk and hhc_clk, respectively, for omap7xx CPUs. Additionally, I added a check in machine_without_vbus_sense for all omap7xx devices, as presently I know of no omap7xx-based devices that have vbus sense, and it made more sense to me to use a cpu check here than to spell out each machine one at a time. Finally, DMA is disabled for omap7xx, as it causes problems with these chips. Cc: linux-usb@vger.kernel.org Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by:
