* OMAP3: cpuidle: Update statistics for correct stateSanjeev Premi2010-02-23
| | | | | | | | | | | | | | | | | | | When 'enable_off_mode' is 0, the target power state for MPU and CORE was locally changed to PWRDM_POWER_RET but, the statistics are updated for idle state originally selected by the governor. This patch 'invalidates' the idle states that lead either of MPU or Core to PWRDM_POWER_OFF state when 'enable_off_mode' is '0'. The states are valid once 'enable_off_mode' is set to '1'. Added function next_valid_state() to check if current state is valid; else get the next valid state. It is called from omap3_enter_idle_bm().

| * omap: Remove DEBUG_FS dependency for mux name checkingRanjith Lohithakshan2010-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for a valid mux name should be performed regardless of whether DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] last sysfs file: Modules linked in: CPU: 0 Not tainted (2.6.33-rc8 #10) PC is at strcmp+0x18/0x40 LR is at omap_mux_init_signal+0x68/0x14c ... This fixes the issue currently seen with boards not booting up if DEBUG_FS is not enabled in defconfig. Note that the earlier ifndef + ifdef now becomes simpler ifdef else: If CONFIG_OMAP_MUX is selected, we use pin names. If it's not selected, we only want the GPIO to mux register mapping.

* | omap_hsmmc: Allow for a shared VccQAdrian Hunter2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EMMC can have two voltage supplies, Vcc and VccQ which are implemented in the code as consumer supplies vmmc and vmmc_aux. If the regulator that supplies vmmc_aux is shared with other consumers, then sending it to sleep will disrupt those consumers. However, the TWL4030-family regulators may have OFF remapped to SLEEP, in which case 'regulator_disable()' will put the regulator to sleep only when all consumers are disabled - which is the desired behaviour. This patch adds a platform data field to allow that option. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* | omap: RX51: Remux to pull eMMC lines down when powering offAdrian Hunter2010-02-15
| | | | | | | | | | | | | | | | | | | | | | It has been discovered that, when eMMC is powered off, current will flow from OMAP eMMC data pull-ups to the eMMC voltage supply. Configuring pads for OMAP off-mode does not help because eMMC is powered off independently of OMAP off-mode. Hence the pads are now re-configured when eMMC is powered on or off.

* | omap_hsmmc: Move gpio and regulator control from board fileAdrian Hunter2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the setup code for GPIO's and Voltage Regulators from the board file mmc-twl4030.c to the driver omap_hsmmc.c. PBIAS and other system control configuration remains in the board file. Moving GPIO code to the driver makes the board initialisation code independent of when GPIO's are defined. That makes the board initialisation now entirely independent of its original twl4030 roots. Moving Voltage Regulator code to the driver allows for further development of regulator support in the core MMC code. It also permits the MMC core to be compiled as a module, because the board code no longer calls MMC core functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for flashes on 3430SDP boards. All three NAND, NOR and OneNAND are supported. I have tested it on 3430SDP (ES2 and ES3.1). This patch can be treated as an example to "how to utilize": 'gpmc-nand.c' and 'board-sdp-flash.c'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds 'board-sdp-flash.c', which could be utilized by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp). This file does initialization for all three flash devices present in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number dynamically using switch setting information (S8: 1-4). This also expects partition information from core board files (for ex: board-3430sdp.c). Which allows to choose different default partitions for different boards. A new structure is created for this purpose: 'flash_partitions' in 'mach/board-sdp.h'. This has two members: 1. struct mtd_partition *parts 2. int nr_parts A board file is expected to fill this structure and pass it to 'sdp-flsash-init'. Partition information should be passed in structure array of 'flash_partitions'. Partition information should be passed in below sequence in array: NOR OneNAND NAND Signed-off-by: Vimal Singh <vimalsingh@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
