It has a built-in programmable execution engine that can be programmed to operate as almost any serial bus (I2C, SPI, EasyScale, and others). This patch series implements a driver stack that looks like the following: +--------+ | eeprom | . . . +--------+ +-----------+ +--------------+ +---------+ | regulator | . . . | i2c-gpio | | 1-wire | . . . +-----------+ +--------------+ +---------+ +----------------------+ +--------------------------------+ | ssp-spi | | ssp-gpio | +----------------------+ +--------------------------------+ +----------------------------------------------------------+ | ssp | +----------------------------------------------------------+ Changes between v2 and v3 of this series: - Minor cleanups in Kconfig and Makefile ordering Changes between v1 and v2 of this series: - Replaced open()/close() semantics with dynamic platform_device registration on SSP probe. - Removed user-land interface to regulator registers - More sensible regulator constraints - Other minor cleanups Cyril Chemparathy (12): misc: add driver for sequencer serial port davinci: add tnetv107x ssp platform device davinci: add ssp config for tnetv107x evm board spi: add ti-ssp spi master driver davinci: add spi devices on tnetv107x evm regulator: add driver for tps6524x regulator davinci: add tnetv107x evm regulators gpio: add ti-ssp virtual gpio driver davinci: add tnetv107x evm ti-ssp gpio device backlight: add support for tps6116x controller davinci: add tnetv107x evm backlight device davinci: add tnetv107x evm i2c eeprom device arch/arm/mach-davinci/board-tnetv107x-evm.c | 199 +++++++ arch/arm/mach-davinci/devices-tnetv107x.c | 25 + arch/arm/mach-davinci/include/mach/ti_ssp.h | 98 ++++ arch/arm/mach-davinci/include/mach/tnetv107x.h | 2 + arch/arm/mach-davinci/tnetv107x.c | 2 +- drivers/gpio/Kconfig | 10 + drivers/gpio/Makefile | 1 + drivers/gpio/ti-ssp-gpio.c | 200 +++++++ drivers/misc/Kconfig | 11 + drivers/misc/Makefile | 1 + drivers/misc/ti_ssp.c | 436 +++++++++++++++ drivers/regulator/Kconfig | 10 + drivers/regulator/Makefile | 1 + drivers/regulator/tps6524x-regulator.c | 692 ++++++++++++++++++++++++ drivers/spi/Kconfig | 7 + drivers/spi/Makefile | 1 + drivers/spi/spi_ti_ssp.c | 397 ++++++++++++++ drivers/video/backlight/Kconfig | 7 + drivers/video/backlight/Makefile | 2 +- drivers/video/backlight/tps6116x.c | 340 ++++++++++++ 20 files changed, 2440 insertions(+), 2 deletions(-) create mode 100644 arch/arm/mach-davinci/include/mach/ti_ssp.h create mode 100644 drivers/gpio/ti-ssp-gpio.c create mode 100644 drivers/misc/ti_ssp.c create mode 100644 drivers/regulator/tps6524x-regulator.c create mode 100644 drivers/spi/spi_ti_ssp.c create mode 100644 drivers/video/backlight/tps6116x.c ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev
