2015-05-18BCM270x: Use bcm2708-vcioNoralf Trønnes1-1/+1
Use bcm2708-vcio instead of the arch version. Change affected drivers to use linux/platform_data/mailbox-bcm2708.h Signed-off-by: Noralf Trønnes <>
2015-05-18dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.cNoralf Trønnes1-1/+1
Merge the legacy DMA API driver with bcm2708-dmaengine. This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox driver is also needed). Changes to the dma.c code: - Use BIT() macro. - Cutdown some comments to one line. - Add mutex to vc_dmaman and use this, since the dev lock is locked during probing of the engine part. - Add global g_dmaman variable since drvdata is used by the engine part. - Restructure for readability: vc_dmaman_chan_alloc() vc_dmaman_chan_free() bcm_dma_chan_free() - Restructure bcm_dma_chan_alloc() to simplify error handling. - Use device irq resources instead of hardcoded bcm_dma_irqs table. - Remove dev_dmaman_register() and code it directly. - Remove dev_dmaman_deregister() and code it directly. - Simplify bcm_dmaman_probe() using devm_* functions. - Get dmachans from DT if available. - Keep 'dma.dmachans' module argument name for backwards compatibility. Make it available on ARCH_BCM2835 as well. Signed-off-by: Noralf Trønnes <>
2015-05-18BCM2708: Migrate to the Common Clock Frameworknotro1-1/+1
As part of moving towards using Device Tree, the Common Clock Framework has to be used instead of the BCM2708 clock implementation. Selecting COMMON_CLK removes the need to set CLKDEV_LOOKUP and HAVE_CLK explicitly. CONFIG_ARCH_BCM2708_CHIPIT #ifdef's are removed. They are no longer in use. Signed-off-by: Noralf Tronnes <>
2015-05-18Add bcm2708_gpio driverpopcornmix1-0/+1
Signed-off-by: popcornmix <> bcm2708: Add extension to configure internal pulls The bcm2708 gpio controller supports internal pulls to be used as pull-up, pull-down or being entirely disabled. As it can be useful for a driver to change the pull configuration from it's default pull-down state, add an extension which allows configuring the pull per gpio. Signed-off-by: Julian Scheel <> bcm2708-gpio: Revert the use of pinctrl_request_gpio In non-DT systems, pinctrl_request_gpio always fails causing "requests probe deferral" messages. In DT systems, it isn't useful because the reference counting is independent of the normal pinctrl pin reservations. gpio: Only clear the currently occurring interrupt. Avoids losing interrupts See: linux #760 bcm2708_gpio: Avoid calling irq_unmask for all interrupts When setting up the interrupts, specify that the handle_simple_irq handler should be used. This leaves interrupt acknowledgement to the caller, and prevents irq_unmask from being called for all interrupts. Issue: linux #760
