2016-04-27ARM: davinci: Move clock init after ioremap.David Lechner1-0/+1
Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem. The davinci_common_init() function must be called before the ioremap, so the clock init is now split out as separate function. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

2011-09-17ARM: davinci: Explicitly set channel controllers' default queuesIdo Yariv1-0/+1
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.

2010-05-13Davinci: jtag_id - use ioremap()Cyril Chemparathy1-1/+1
This patch replaces the jtag id base info in davinci_soc_info with a physical address which is then ioremap()ed within common code. This patch (in combination with a similar change for PSC) will allow us to eliminate the SYSCFG nastiness in DA8xx code.

2010-05-13Davinci: gpio - use ioremap()Cyril Chemparathy1-1/+1
This patch modifies the gpio_base definition in davinci_soc_info to be a physical address, which is then ioremap()ed by the gpio initialization function. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-06Davinci: watchdog reset separation across socsCyril Chemparathy1-0/+1
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.
