* OMAP3: hwmod: support to specify the offset position of various SYSCONFIG ↵Thara Gopinath2010-02-244-29/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | register bits. In OMAP3 Some modules like Smartreflex do not have the regular sysconfig register.Instead clockactivity bits are part of another register at a different bit position than the usual bit positions 8 and 9. In OMAP4, a new scheme is available due to the new protocol between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG bitfields position will be different. The IP_REVISION register should be at offset 0x00. It should contain a SCHEME field. From this we can determine whether the IP follows legacy scheme or the new scheme. 31:30 SCHEME Used to distinguish between old scheme and current. Read 0x0: Legacy protocol. Read 0x1: New PRCM protocol defined for new OMAP4 IPs For legacy IP 13:12 MIDLEMODE 11:8 CLOCKACTIVITY 6 EMUSOFT 5 EMUFREE 4:3 SIDLEMODE 2 ENAWAKEUP 1 SOFTRESET 0 AUTOIDLE For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target): 5:4 STANDBYMODE (Ex MIDLEMODE) 3:2 IDLEMODE (Ex SIDLEMODE) 1 FREEEMU (Ex EMUFREE) 0 SOFTRESET Unfortunately In OMAP4 also some IPs will not follow any of these two schemes. This is the case at least for McASP, SmartReflex and some security IPs. This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which can be used by the hwmod structures to specify the offsets for the sysconfig register of the IP.Also two static structures omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined which can be used directly to populate the sysc_fields if the IP follows legacy or new OMAP4 scheme. If the IP follows none of these two schemes a new omap_hwmod_sysc_fields structure has to be defined and passed as part of omap_hwmod_sysconfig.

* OMAP2/3 clock: Extend find_idlest() to pass back idle state valueRanjith Lohithakshan2010-02-249-23/+52
| | | | | | | | | | | | | | | | Current implementation defines clock idle state indicators based on the cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide manner. This patch extends the find_idlest() function in clkops to pass back the idle state indicator for that clock, thus allowing idle state indicators to be defined on a per clock basis if required. This is specifically needed on AM35xx devices as the new IPSS clocks indicates the idle status (0 is idle, 1 is ready) in a way just opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

* OMAP3 PM: Adding counters for power domain logic off and mem off during ↵Thara Gopinath2010-02-243-0/+32
| | | | | | | | | | | | | | | | | | | | | | retention. This patch adds counters to keep track of whether the powerdomain logic or software controllable memory banks are turned off when the power domain enters retention. During power domain retention if logic gets turned off, the scenario is known as Open Switch Retention. Also during retention s/w controllable memory banks of a power domain can be chosen to be kept in retention or off. This patch adds one counter per powerdomain to track the power domain logic state during retention. Number of memory bank state counters added depends on the number of software controllable memory banks of the powerdomain.

* OMAP: omap_device: add omap_device_is_valid()Kevin Hilman2010-02-242-0/+18
| | | | | | | | | | | | | | | | | | The omap_device struct contains a 'struct platform_device'. Normally, converting a platform_device pointer to an omap_device pointer consists of simply doing a container_of(), as is done currently by the to_omap_device() macro. However, if this is attempted when using platform_device that has not been created as part of the omap_device creation, the container_of() will point to a memory location before the platform_device pointer which will contain random data. Therefore, we need a way to detect valid omap_device pointers. This patch solves this by using the simple magic number approach.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for a valid mux name should be performed regardless of whether DEBUG_FS is enabled or not.

This fixes the issue currently seen with boards not booting up if DEBUG_FS is not enabled in defconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 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 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'.

With this patch, I have finally managed to get rid of all random playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before that, values read back from McBSP registers to be used for updating them happened to be errornous. From the hardware side, the issue appeared to be caused by a relatively high power requirements of an external USB adapter connected to the board's printer dedicated USB port. I think there is one important point that makes this patch worth of applying, apart from my hardware quality. With the current code, if it ever happens to any machine, no matter if OMAP1510 or newer, to read incorrect value from a McBSP register, this wrong value will get written back without any checking. That can lead to hardware damage if, for example, an input pin is turned into output as a result.

* | omap: McBSP: Use macros for all register read/write operationsJanusz Krzysztofik2010-02-151-22/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several places where readw()/writew() functions are used instead of OMAP_MCBSP_READ()/WRITE() macros for manipulating McBSP registers. Replace them with macros to ensure consistent behaviour after caching is introduced. Tested on OMAP1510 based Amstrad Delta. Compile-tested with omap_3430sdp_defconfig.

| | | | | | | | | | | | | | | | | | | | | | There was a potential risk that the following "memset" could override its range if a given address was not the 1st entry of a largepage.
