Misc updates from linux-omap tree, mostly to update common device initialization and add missing defines from linux-omap tree. Also some changes to make room for adding 34xx in following patches. Note that the I2C resources are now set up in arch/arm/plat-omap/i2c.c helper, and can be removed from devices.c. Signed-off-by: NTony Lindgren <tony@atomide.com>

Some register offsets are different for 242x and 243x. This will allow compiling sleep code for both chips into the same kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the omap24xx_cpu_suspend instead of loading the values since the only. Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL instead of the address as that's what omap24xx_cpu_suspend expects to determine between DDR and SDR. This bug has not been noticed as the boards seem to have DDR instead of SDR. Note that some PM patches are still missing. The PM patches will be added later on once the base files are in sync with linux-omap tree. Signed-off-by: NTony Lindgren <tony@atomide.com>

gpio.c wilfully casts physical addresses to void __iomem * and then fixes them up at runtime using: bank->base = IO_ADDRESS(bank->base); where accesses prior to this fixup are via omap_read/omap_write, and after are by __raw_read/__raw_write. This doesn't lend itself to static checking, nor to easy understanding of the code. And so, OMAP_MPUIO_BASE gets to be the right type - integer like since it's a physical address, not a MMIO pointer.

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies for use with __raw_{read|write}* for accessing registers. Therefore, these macros should return (void __iomem *) cookies, not integer values. Doing this improves typechecking, and means we can find those places where, eg, DMA controllers are incorrectly given virtual addresses to DMA to, or physical addresses are thrown through a virtual to physical address translation.

OMAP3430ES2+ introduces a new feature: optional powerdomain context hardware save-and-restore (SAR). Currently, this feature only applies to USBHOST and USBTLL module context when the USBHOST or CORE powerdomains enter a low-power sleep state[1]. This feature avoids re-enumeration of USB devices when the powerdomains return from idle, which is potentially time-consuming. This patch adds support for enabling and disabling hardware save-and-restore to the powerdomain code. Three new functions are added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and pwrdm_can_hdwr_sar(). A new struct powerdomain "flags" field is added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with SAR support. Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com> for clarifying the purpose of these bits. 1. For the USBHOST controller module, context loss occurs when the USBHOST powerdomain enters off-idle. For USBTLL, context loss occurs either if CORE enters off-idle, or if the CORE logic is configured to turn off when CORE enters retention-idle (OSWR). 34xx ES2 TRM 4.8.6.1.1, 4.8.6.1.2 Signed-off-by: NPaul Walmsley <paul@pwsan.com> Signed-off-by: NTony Lindgren <tony@atomide.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This patch creates an interface to the clockdomain registers in the PRM/CM modules on OMAP2/3. This interface is intended to be used by PM code, e.g., pm.c; not by device drivers directly. The patch also adds clockdomain usecount tracking. This is intended to be called whenever the first clock in a clockdomain is enabled, or when the last enabled clock in a clockdomain is disabled. If the clockdomain is in software-supervised mode, the code will force-wakeup or force-sleep the clockdomain. If the clockdomain is in hardware-supervised mode, the first clock enable will add sleep and wakeup dependencies on a user-selectable set of parent domains (usually MPU & IVA2), and the disable will remove them. Each clockdomain will be defined in later patches as static structures. The clockdomain structures are linked into a list at boot by clkdm_register(), similar to the OMAP clock code. The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which when enabled will emit verbose debug messages via pr_debug().

OMAP at least gets the return type(s) for the DMA translation functions wrong, which can lead to subtle errors. Avoid this by moving the DMA translation functions to asm/dma-mapping.h, and converting them to inline functions. Fix the OMAP DMA translation macros to use the correct argument and result types. Also, remove the unnecessary casts in dmabounce.c. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This adds a simple sysfs interface for GPIOs. /sys/class/gpio /export ... asks the kernel to export a GPIO to userspace /unexport ... to return a GPIO to the kernel /gpioN ... for each exported GPIO #N /value ... always readable, writes fail for input GPIOs /direction ... r/w as: in, out (default low); write high, low /gpiochipN ... for each gpiochip; #N is its first GPIO /base ... (r/o) same as N /label ... (r/o) descriptive, not necessarily unique /ngpio ... (r/o) number of GPIOs; numbered N .. N+(ngpio - 1) GPIOs claimed by kernel code may be exported by its owner using a new gpio_export() call, which should be most useful for driver debugging. Such exports may optionally be done without a "direction" attribute. Userspace may ask to take over a GPIO by writing to a sysfs control file, helping to cope with incomplete board support or other "one-off" requirements that don't merit full kernel support: echo 23 > /sys/class/gpio/export ... will gpio_request(23, "sysfs") and gpio_export(23); use /sys/class/gpio/gpio-23/direction to (re)configure it, when that GPIO can be used as both input and output. echo 23 > /sys/class/gpio/unexport ... will gpio_free(23), when it was exported as above The extra D-space footprint is a few hundred bytes, except for the sysfs resources associated with each exported GPIO. The additional I-space footprint is about two thirds of the current size of gpiolib (!). Since no /dev node creation is involved, no "udev" support is needed. Related changes: * This adds a device pointer to "struct gpio_chip". When GPIO providers initialize that, sysfs gpio class devices become children of that device instead of being "virtual" devices. * The (few) gpio_chip providers which have such a device node have been updated. * Some gpio_chip drivers also needed to update their module "owner" field ... for which missing kerneldoc was added. * Some gpio_chips don't support input GPIOs. Those GPIOs are now flagged appropriately when the chip is registered. Based on previous patches, and discussion both on and off LKML. A Documentation/ABI/testing/sysfs-gpio update is ready to submit once this merges to mainline.

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

debugfs can provide the infrastructure to trace the dependencies of clock tree hierarchy quite visibly. This patch enables to keep track of clock tree hierarchy and expose their attributes under each clock directry as below: omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/ /debug/clock/omap_32k_fck/ |-- gpt10_fck |-- gpt11_fck |-- gpt1_fck |-- per_32k_alwon_fck | |-- gpio2_fck | |-- gpio3_fck | |-- gpio4_fck | |-- gpio5_fck | |-- gpio6_fck | `-- wdt3_fck |-- ts_fck `-- wkup_32k_fck |-- gpio1_fck `-- wdt2_fck 14 directories omap:~# tree /debug/clock/omap_32k_fck/gpt10_fck/ /debug/clock/omap_32k_fck/gpt10_fck/ |-- flags |-- rate `-- usecount 0 directories, 3 files Although, compared with David Brownell's small patch, this may look bit overkilling, I expect that this debugfs can deal with other PRCM complexities at the same time. For example, powerdomain dependencies can be expressed by using symbolic links of these clocks if powerdomain supports dubgfs as well.
