At some point omap2 changed the bits for GET_OMAP_CLASS, which broke 15xx detection on 730 as noticed by Russell King. This patch fixes omap2 cpu detection to respect the original GET_OMAP_CLASS, and simplifies the detection for 34xx. Signed-off-by: NTony Lindgren <tony@atomide.com>

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.

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.

Add minimal omap3430 support based on earlier patches from Syed Mohammed Khasim. Also merge in omap34xx SRAM support from Karthik Dasu and use consistent naming for sram init functions. Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.

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>

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>
