* omap mmc: force MMC module reset on bootKevin Hilman2008-12-10
| | | | | | | | | | | The bootloader may leave the MMC in a state which prevents hitting retention. Even when MMC is not compiled in, each MMC module needs to be forced into reset. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* omap mmc: Add low-level initialization for hsmmc controllerTony Lindgren2008-12-10
| | | | | | | | | | | | | | | | | | | | | | | Add low-level initialization for hsmmc controller. Merged into this patch patch are various improvments and board support by Grazvydas Ignotas and David Brownell. Also change wire4 to be wires, as some newer controllers support 8 data lines.

* omap mmc: Add better MMC low-level initTony Lindgren2008-12-10
| | | | | | | | | | | | | | | | | | | | | | This will simplify the MMC low-level init, and make it more flexible to add support for a newer MMC controller in the following patches. The patch rearranges platform data and gets rid of slot vs controller confusion in the old data structures. Also fix device id numbering in the clock code. Some code snippets are based on an earlier patch by Russell King <linux@arm.linux.org.uk>. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>
* omap mmc: Remove broken MMC init codeTony Lindgren2008-12-10
| | | | | | | | | | | | | Most of the omap1 MMC boards got broken by an earlier patch 138ab9f8321f67c71984ca43222efa71b0a0a0a9. If you look closely, the MMC init funtions are pretty much just stubs. Remove broken init code to make room for cleaner MMC init code. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP2: Fix cpu detectionTony Lindgren2008-12-10

* ARM: OMAP: switch to gpio_direction_outputDavid Brownell2008-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | More conversion to the standard GPIO interfaces: stop using omap_set_gpio_direction() entirely, and switch over to the gpio_direction_output() call. Note that because gpio_direction_output() includes the initial value, this change isn't quite transparent. - For the call sites which defined an initial value either before or after setting the direction, that value was used. When that value was previously assigned afterwards, this could eliminate a brief output glitch ... and possibly change behavior. In a few cases (LCDs) several values were assigned together ... those were re-arranged to match the explicit sequence provided. - Some call sites didn't define such a value; so I chose an initial "off/reset" value that seemed to default to "off". In short, files touched by this patch might notice some small changes in startup behavior (with trivial fixes).

| | | | | | | | | | | | | | | | This patch replaces some legacy OMAP GPIO calls with the "new" (not really, any more!) calls that work on most platforms. The calls addressed by this patch are the simple ones to get and set values ... for code that's in mainline, including the implementations of those calls. Except for the declarations and definitions of those calls, all of these changes were performed by a simple SED script. Plus, a few "if() set() else set()" branches were merged by hand.

* ARM: OMAP: Enable GPIO debounce clock only when debounce is enabled v3Jouni Hogander2008-12-10
| | | | | | | | | | | | | | | | | | | This patch changes gpio "driver" to enable debounce clock for gpio-bank only when debounce is enabled for some gpio in that bank. Gpio functional clocks are also renamed in clock tree, gpioX_fck -> gpioX_dbck. This patch triggers problem with gpio wake-up and Omap3. Gpios in PER domain aren't capable to generate wake-up if PER domain is in sleep state. For this iopad wake-up should be used and needed pad configuration should be done. Enabling iopad wake-up for gpio pads is left for bootloader or omap mux configuration in kernel.

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.

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: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Associate each OMAP24xx clock in arch/arm/mach-omap2/clock24xx.h with a clockdomain. Also move the L4 clock up higher in the file in preparation to define the SSI L4 iclk. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thie patch adds code to the powerdomain layer to track the clockdomains associated with each powerdomain. It also modifies the clockdomain code to register clockdomains with their corresponding powerdomain when the clockdomain is registered.

| | * | ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain codePaul Walmsley2008-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
