For modules having single clock, clk_get should be done with dev_id. But current davinci implementation handles multiple instances of the UART devices with single platform_device_register.

2013-01-03ARM: davinci: da8xx_register_spi() should not register SPI board infoVivien Didelot
Without this patch, da8xx_register_spi() registers the SPI board info, the SPI controller, and sets its number of chipselect to the size of the static spi_board_info array. This is bad because a SPI board info may declare devices for different SPI buses, and because other code can also call spi_register_board_info() (e.g. a daughter board might provide additional SPI devices). This patch removes the spi_register_board_info() call from da8xx_register_spi(), renames this last one to da8xx_register_spi_bus() to be more explicit, takes the number of chipselect as a function parameter, and updates the impacted board-da8{3,5}0-evm.c, and board-mityomapl138.c files accordingly. It also sets the SPI platform data static, as it doesn't need to be exported.

2011-09-17ARM: davinci: Explicitly set channel controllers' default queuesIdo Yariv
Davinci platforms may define a default queue for each channel controller. If one is not defined, the default queue is set to EVENTQ_1. However, there's no way to distinguish between an unset default queue to one that is set to EVENTQ_0, as EVENTQ_0 = 0. Explicitly specify the default queue for all channel controllers on all Davinci platforms to EVENTQ_1, and don't overwrite it in the EDMA probe function. One exception is the DA850 board, for which EVENTQ_1 is not a valid option for its second channel controller. Use EVENTQ_0 instead for that channel controller.

2010-05-06Davinci: watchdog reset separation across socsCyril Chemparathy
The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.
