2011-01-10arm: omap4: pandaboard: turn on PHY reference clock at initAnand Gadiyar
The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz reference clock. This clock is provided from the OMAP4's fref_clk3 pad. Recent changes to clock44xx_data.c made the clock framework aware of the existence of these fref_clk[i] lines. If the option CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the clock framework will turn these clocks off during bootup. Explicitly request and keep this clock enabled at init for the Pandaboard, so that the PHY receives this clock at all times.

2010-12-22OMAP4: Smartreflex framework extensionsThara Gopinath
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>

2010-12-22OMAP3: PM: Adding smartreflex class3 driverThara Gopinath
Smartreflex Class3 implementation continuously monitors silicon performance and instructs the Voltage Processors to increase or decrease the voltage. This patch adds smartreflex class 3 driver. This driver hooks up with the generic smartreflex driver smartreflex.c to abstract out class specific implementations out of the generic driver. Class3 driver is chosen as the default class driver for smartreflex. If any other class driver needs to be implemented, the init of that driver should be called from the board file. That way the new class driver will over-ride the Class3 driver. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-12-22OMAP3: PM: Adding smartreflex device file.Thara Gopinath
This patch adds support for device registration of various smartreflex module present in the system. This patch introduces the platform data for smartreflex devices which include the efused n-target vaules, a parameter to indicate whether smartreflex autocompensation needs to be enabled on init or not. An API omap_enable_smartreflex_on_init is provided for the board files to enable smartreflex autocompensation during system boot up.

2010-12-22OMAP3: PM: Adding smartreflex driver support.Thara Gopinath
SmartReflex modules do adaptive voltage control for real-time voltage adjustments. 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. Major contributors to this driver are Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley, Nishant Menon, Kevin Hilman.

2010-12-22OMAP3: PM: Adding voltage driver support.Thara Gopinath
This patch adds voltage driver support for OMAP3. 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.

2010-12-22Keyboard: omap-keypad: use matrix_keypad.hJanusz Krzysztofik
Most keypad drivers make use of the <linux/input/matrix_keypad.h> defined macros, structures and inline functions. Convert omap-keypad driver to use those as well, as suggested by a compile time warning, hardcoded into the OMAP <palt/keypad.h>. Created against linux-2.6.37-rc5. Tested on Amstrad Delta. Compile tested with omap1_defconfig and omap2plus_defconfig shrinked to board-h4.
