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 v5 and v4 of this series: - Moved drivers from misc/gpio/spi to mfd - Removed implicit init-time iosel setup - Minor cleanups in backlight driver Changes between v3 and v4 of this series: - Replaced polled wait for sequence termination with interrupt - Improved locking within SSP driver - Other minor cleanups 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 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 | 192 +++++++ arch/arm/mach-davinci/devices-tnetv107x.c | 25 + arch/arm/mach-davinci/include/mach/tnetv107x.h | 2 + arch/arm/mach-davinci/tnetv107x.c | 2 +- drivers/mfd/Kconfig | 31 + drivers/mfd/Makefile | 3 + drivers/mfd/ti-ssp-gpio.c | 205 +++++++ drivers/mfd/ti-ssp-spi.c | 402 ++++++++++++++ drivers/mfd/ti-ssp.c | 475 ++++++++++++++++ drivers/regulator/Kconfig | 10 + drivers/regulator/Makefile | 1 + drivers/regulator/tps6524x-regulator.c | 692 ++++++++++++++++++++++++ drivers/video/backlight/Kconfig | 7 + drivers/video/backlight/Makefile | 2 +- drivers/video/backlight/tps6116x.c | 339 ++++++++++++ include/linux/mfd/ti_ssp.h | 97 ++++ 16 files changed, 2483 insertions(+), 2 deletions(-) create mode 100644 drivers/mfd/ti-ssp-gpio.c create mode 100644 drivers/mfd/ti-ssp-spi.c create mode 100644 drivers/mfd/ti-ssp.c create mode 100644 drivers/regulator/tps6524x-regulator.c create mode 100644 drivers/video/backlight/tps6116x.c create mode 100644 include/linux/mfd/ti_ssp.h ------------------------------------------------------------------------------ Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.
