Move platform_device_register() for serial device to omap_serial_init() There is no need to have arch_initcall() dependency in serial as already board files call the function omap_serial_init() Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Make 770 LCD work by adding clk_add_alias(). Also remove the old unused functions. Note that the clk_add_alias() could probably be moved to arch/arm/clkdev.c later on.

Convert the board-rx51 smc91x code to be generic and make the boards to use it. This allows future recalculation of the timings when the source clock gets scaled. Also correct the rx51 interrupt to be IORESOURCE_IRQ_HIGHLEVEL. Thanks to Paul Walmsley <paul@pwsan.com> for better GPMC timing calculations. Signed-off-by: Tony Lindgren <tony@atomide.com>

Add generic onenand support when connected to GPMC and make the boards to use it. The patch has been modified to make it more generic to support all the boards with GPMC. The patch also remove unused prototype for omap2_onenand_rephase(void). Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC and setting the GPMC timings in the bootloader. Setting the GPMC timings in the bootloader will not allow supporting frequency scaling for the onenand source clock. Signed-off-by: Tony Lindgren <tony@atomide.com>

Original OMAP DMA chaining design had chain_id as one of the callback parameters. Patch 538528de changed it to use logical channel instead. Correct the naming for callback to also use logical channel number instead of the chain_id.

Update OMAP1-specific PM infrastructure. This is a sync of what is in linux-omap for OMAP1. This mostly de-couples OMAP1 PM from OMAP2/3 PM and renames things accordingly, and removes omap2/3 specific code from OMAP1 specific headers.

Add D2D clocks (modem_fck, sad2d_ick, mad2d_ick) to clock framework and ensure that auto-idle bits are set for these clocks during PRCM init. Also add omap3_d2d_idle() function called durint PRCM setup which ensures D2D pins are MUX'd correctly to enable retention for standalone (no-modem) devices.

This patch makes it possible to change uart sleep timeout. New sysfs entry is added (/sys/devices/platform/serial8250.<uart>/sleep_timeout) Writing zero will disable the timeout feature and prevent UART clocks from being disabled. Also default timeout is increased to 5 second to make serial console more usable. Original patch was written by Tero Kristo.

This patch allows the UART clocks to be disabled when the OMAP UARTs are inactive, thus permitting the chip to hit retention in idle. After the expiration of an activity timer, each UART is allowed to disable its clocks so the system can enter retention. The activity timer is (re)activated on any UART interrupt, UART wake event or any IO pad wakeup. The actual disable of the UART clocks is done in the 'prepare_idle' hook called from the OMAP idle loop. While the activity timer is active, the smart-idle mode of the UART is also disabled. This is due to a "feature" of the UART module that after a UART wakeup, the smart-idle mode may be entered before the UART has communicated the interrupt, or upon TX, an idle mode may be entered before the TX FIFOs are emptied. Upon suspend, the 'prepare_suspend' hook cancels any pending activity timers and allows the clocks to be disabled immediately. In addition, upon disabling clocks the UART state is saved in case of an off-mode transition while clocks are off. Special thanks to Tero Kristo for the initial ideas and first versions of UART idle support, and to Jouni Hogander for extra testing and bugfixes. Tested on OMAP3 (Beagle, RX51, SDP, EVM) and OMAP2 (n810) Cc: Tero Kristo <tero.kristo@nokia.com> Cc: Jouni Hogander <jouni.hogander@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

This patch is to sync the core linux-omap PM code with mainline. This code has evolved and been used for a while the linux-omap tree, but the attempt here is to finally get this into mainline. Following this will be a series of patches from the 'PM branch' of the linux-omap tree to add full PM hardware support from the linux-omap tree. Much of this PM core code was written by Jouni Hogander with significant contributions from Paul Walmsley as well as many others from Nokia, Texas Instruments and linux-omap community.

This reverts commit 5461af5a. Adding a disable hook to the irq_chip is not the way to fix the problem being addressed by this patch. Instead, we need to fix support for [enable|disable]_irq_wake(). Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
