2011-02-23OMAP: fix fncpy API callJean Pihet
Fix a potential problem with function types when calling the fncpy API to copy the PM code functions to SRAM. Signed-off-by: Jean Pihet <j-pihet@ti.com>
2011-02-23omap: use fncpy to copy the PM code functions to SRAMJean Pihet
The new fncpy API is better suited for copying some code to SRAM at runtime. This patch changes the ad-hoc code to the more generic fncpy API. Tested OK on OMAP3 in low power modes (RET/OFF) using omap2plus_defconfig with !CONFIG_THUMB2_KERNEL. Compile tested on OMAP1/2 using omap1_defconfig.

2011-02-21OMAP: Introduce device scale implementationVishwanath BS
This patch adds omap_device_scale API which can be used to generic device rate scaling. Based on original patch from Thara. Signed-off-by: Vishwanath BS <vishwanath.bs@ti.com> Cc: Thara Gopinath <thara@ti.com>
2011-02-21OMAP: Introduce dependent voltage domain supportVishwanath BS
There could be dependencies between various voltage domains for maintaining system performance or hardware limitation reasons like VDD<X> should be at voltage v1 when VDD<Y> is at voltage v2. This patch introduce dependent vdd information structures in the voltage layer which can be used to populate these dependencies for a voltage domain. This patch also adds support to scale the dependent vdd and the scalable devices belonging to it during the scaling of a main vdd through omap_voltage_scale. As part of this, some of the voltage layer structure definitions are moved from voltage.c to voltage.h as it needs to be used in the dvfs layer for dependency voltage handling.

2011-02-21OMAP: Introduce device specific set rate and get rate in omap_device structureThara Gopinath
This patch extends the omap_device structure to contain pointers to scale the operating rate of the device and to retrieve the operating rate of the device. This patch also adds the three new APIs in the omap device layer namely omap_device_set_rate that can be called to set a new operating rate for a device, omap_device_get_rate that can be called to retrieve the operating frequency for a device and omap_device_register_dvfs_callbacks to register the device specific set_rate and get_rate functions. The omap_device_set_rate and omap_device_get_rate does some routine error checks and finally calls into the device specific set_rate and get_rate APIs populated through omap_device_populate_rate_fns.

2011-02-21OMAP: Introduce accessory APIs for DVFSVishwanath BS
This patch introduces accessory APIs for DVFS. Data structures added: 1. omap_dev_user_list: This structure maintains list of frequency requests per device basis. When a device needs to be scaled to a particular frequency, This list is searched to find the maximum request for a given device. If noone has placed any request, device frequency is obtained from device opp table. 2. omap_vdd_dev_list: This strcucture stores device list per vdd basis. Whenever a device is registered with a vdd, it is added to this list. 3. omap_vdd_user_list: User list of devices associated with each voltage domain instance. The user list is implemented using plist structure with priority node populated with the voltage values. 4. omap_vdd_dvfs_info: This structure is used to abstract DVFS related information per VDD basis. It holds pointer to corresponding vdd's voltagedomain instance and pointer to user list. Following APIs have been added to operate on above data structures: 1. omap_dvfs_add_vdd_user - API to add a user into omap_vdd_user_list 2. omap_vdd_user_list - API to remove a user from omap_vdd_user_list 3. omap_dvfs_register_device - API to register a device with vdd 4. omap_dvfs_add_freq_request - API to add a frequency request into omap_dev_user_list 5. omap_dvfs_remove_freq_request - API to remove a frequency request from omap_dev_user_list 6. omap_dvfs_find_voltage - API to find the opp corresponding to given voltage DVFS layer is initialized and basic data structures are allocated and initialized as part of this. This patch is based on Thara's previous DVFS implementation, but with major rework. Signed-off-by: Vishwanath BS <vishwanath.bs@ti.com> Cc: Thara Gopinath <thara@ti.com>

Hwmod needs database of all IPs in a system. This patch generates the hwmod database for Display Sub System applicable for OMAP3430 and OMAP36xx. DSS is also considered as an IP as DISPC, RFBI and named as dss_core. For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in each IP. This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also the firewall regions are different between 3430es1 and later.

overlay manager. A panel connects to one of the overlay managers of DSS through some interface block. On OMAP4, specifying the type of the display is not sufficient to conclude which manager the panel should be connected to. Hence, a new member 'channel' is introduced in omap_dss_device structure to determine which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe() uses this channel parameter to set the correct manager to the corresponding omap_dss_device. The channel parameter is used only once to ensure the correct managers are set for each panel. The parameter dssdev->manager->id will take care of ensuring that the panel and then the interface driver configures the correct DISPC channel. Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

2011-01-07arm: omap: gpio: don't access irq_desc array directlyFelipe Balbi
Instead of accessing the irq_desc array directly we can use irq_to_desc(irq). That will allow us to, if wanted, select SPARSE_IRQ and irq_descs will be added to a radix tree, instead of a array. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-01-07OMAP: GPIO: fix _set_gpio_triggering() for OMAP2+Mika Westerberg
In case on OMAP2+ we call set_24xx_gpio_triggering() instead of updating reg and l values. However, at the end of the function we perform a write: __raw_writel(l, reg); So on OMAP2+ we end up writing 0 to the bank->base which is not correct (typically this points to GPIO_REVISION register). Fix this by returning immediately after call to set_24xx_gpio_triggering(). Signed-off-by: Mika Westerberg <ext-mika.1.westerberg@nokia.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

Replace the page_to_dma() and dma_to_page() macros with their PFN equivalents. This allows us to map parts of memory which do not have a struct page allocated to them to bus addresses. This will be used internally by dma_alloc_coherent()/dma_alloc_writecombine(). Build tested on Versatile, OMAP1, IOP13xx and KS8695.

It appears that arch/arm/mach-omap2/timer-gp.o is needed by OMAP2PLUS.
