* OMAP: DSS2: Add dss_features for omap4 and overlay manager related featuresArchit Taneja2011-01-102-3/+47
| | | | | | | | Initialize a dss_features struct for omap4. Add support for LCD2 manager by introducing a new member in dss_feat_id. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
* OMAP: DSS2: Clean up DISPC color mode validation checksArchit Taneja2011-01-103-48/+14
| | | | | | | | | | | | The supported set of color modes varies for different DISPC pipelines(plane) and omap version. This makes the checks for validation of a color mode more complicated as new omap versions are added. A dss_feature function is created which tells if a color_mode is supported for a plane on the current omap revision.

| | | | | | | | | | | Still keep sharp_ls_panel, since the sharp_ls_panel driver contains blacklight control driver code which will be moved out later.

* OMAP: DSS2: Add generic DPI panel display driverBryan Wu2011-01-104-0/+401
| | | | | | | | | | | | | | Generic DPI panel driver includes the driver and 4 similar panel configurations. It will match the panel name which is passed from platform data and setup the right configurations. With generic DPI panel driver, we can remove those 4 duplicated panel display drivers. In the future, it is simple for us just add new panel configuration date in panel-generic-dpi.c to support new display panel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the smartreflex framework to support OMAP4. The changes are minor like compiling smartreflex Kconfig option for OMAP4 also, and a couple of OMAP4 checks in the smartreflex framework. The change in sr_device.c where new logic has to be introduced for reading the efuse registers is due to the fact that in OMAP4 the efuse registers are 24 bit aligned. A __raw_readl will fail for non-32 bit aligned address and hence the 8-bit read and shift. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

With Smartreflex the power supply voltage can be adapted to the silicon performance(manufacturing process, temperature induced performance, age induced performance etc). There are differnet classes of smartreflex implementation. Class-0: Manufacturing Test Calibration Class-1: Boot-Time Software Calibration Class-2: Continuous Software Calibration Class-3: Continuous Hardware Calibration Class-4: Fully Integrated Power Management OMAP3 has two smartreflex modules one associated with VDD MPU and the other associated with VDD CORE. This patch adds support for smartreflex driver. The driver is designed for Class-1 , Class-2 and Class-3 support and is a platform driver. Smartreflex driver can be enabled through a Kconfig option "SmartReflex support" under "System type"->"TI OMAP implementations" menu. Smartreflex autocompensation feature can be enabled runtime through a debug fs option. To enable smartreflex autocompensation feature echo 1 > /debug/voltage/vdd_<X>/smartreflex/autocomp To disable smartreflex autocompensation feature echo 0 > /debug/voltage/vdd_<X>/smartreflex/autocomp where X can be mpu, core , iva etc. This patch contains code originally in linux omap pm branch.

The driver allows configuring the voltage controller and voltage processors during init and exports APIs to enable/disable voltage processors, scale voltage and reset voltage. The driver maintains the global voltage table on a per VDD basis which contains the various voltages supported by the VDD along with per voltage dependent data like smartreflex efuse offset, errminlimit and voltage processor errorgain. The driver also allows the voltage parameters dependent on the PMIC to be passed from the PMIC file through an API. The driver allows scaling of VDD voltages either through "vc bypass method" or through "vp forceupdate method" the choice being configurable through the board file. This patch contains code originally in linux omap pm branch smartreflex driver. Major contributors to this driver are Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley, Nishant Menon, Kevin Hilman. The separation of PMIC parameters into a separate structure which can be populated from the PMIC file is based on the work of Lun Chang from Motorola in an internal tree.

These dividers are defined by the PRCM specification and without these dividers the rates of the below clocks are calculated incorrectly. This may cause internal peripherals using these clocks to operate at the wrong frequency. - abe_24m_fclk (freq = divided-by-8) - ddrphy_ck (freq = parent divided-by-2) - dll_clk_div_ck (freq = parent divided-by-2) - per_hs_clk_div_ck (freq = parent divided-by-2) - usb_hs_clk_div_ck (freq = parent divided-by-3) - func_12m_fclk (freq = parent divided-by-16) - func_24m_clk (freq = parent divided-by-4) - func_24mc_fclk (freq = parent divided-by-8) - func_48mc_fclk (freq = divided-by-4) - lp_clk_div_ck (freq = divided-by-16) - per_abe_24m_fclk (freq = divided-by-4) Signed-off-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com> Cc: Rajendra Nayak <rnayak@ti.com>

| | * OMAP4: clock data: Keep L3INSTR clock domain modulemode under HW controlSantosh Shilimkar2010-12-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | L3INSTR clock domain is read only register and its reset value is HW_AUTO. The modules withing this clock domain needs to be kept under hardware control. MODULEMODE: - 0x0: Module is disable by software. Any INTRCONN access to module results in an error, except if resulting from a module wakeup (asynchronous wakeup). - 0x1: Module is managed automatically by hardware according to clock domain transition. A clock domain sleep transition put module into idle. A wakeup domain transition put it back into function. If CLKTRCTRL=3, any INTRCONN access to module is always granted. Module clocks may be gated according to the clock domain state. This patch keeps CM_L3INSTR_L3_3_CLKCTRL, CM_L3INSTR_L3_INSTR_CLKCTRL and CM_L3INSTR_INTRCONN_WP1_CLKCTRL module mode under hardware control by using ENABLE_ON_INIT flag. Without this the OMAP4 device OFF mode SAR restore phase aborts during interconnect register restore phase. This can be also handled by doing explicit a clock enable and disable in the low power code since there is no direct module associated with it. But that seems not necessary since the clock domain is under HW control.

| | * OMAP4: powerdomain: Remove L3INIT_PD OFF stateSantosh Shilimkar2010-12-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP4, there is an issue when L3INIT transitions to OFF mode without device OFF. The SAR restore mechanism will not get triggered without wakeup from device OFF and hence the USB host and USB TLL context will not be restored. Hardware team recommended to remove the OFF state support for L3INIT_PD since there is no power impact. It will be removed on next OMAP revision (OMAP4440 and beyond). Hence this patch removed the OFF state from L3INIT_PD. The deepest state supported on L3INIT_PD is OSWR just like CORE_PD and PER_PD Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> [b-cousson@ti.com: update the changelog with next OMAP info] Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
