| * ARM: imx: Add wake functionality to GPIODinh Nguyen2010-10-261-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | Add function definition for irq_chip.set_wake to enable GPIO to wake-up the system. This patch has been tested on a MX51 Babbage system that had suspend code implemented. The set_wake implementation is necessary for a GPIO to wake up a system from suspend.

| | | | | | | | | | | | | | | | | | | | | | | | | | Commit c074512 (imx-esdhc: update devices registration) renamed MX35_INT_MMC_SDHC2 to MX35_INT_ESDHC2 which broke expansion of the MXC_INT_MMC_SDHC2 macro. As (the only user of MXC_INT_MMC_SDHC2) is only used on mx31 use the MX31 prefixed symbol to define its resources. Moreover to reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC prefixed symbols are removed.

* | mm: stack based kmap_atomic()Peter Zijlstra2010-10-262-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep the current interface but ignore the KM_type and use a stack based approach. The advantage is that we get rid of crappy code like: #define __KM_PTE \ (in_nmi() ? KM_NMI_PTE : \ in_irq() ? KM_IRQ_PTE : \ KM_PTE0) and in general can stop worrying about what context we're in and what kmap slots might be appropriate for that. The downside is that FRV kmap_atomic() gets more expensive. For now we use a CPP trick suggested by Andrew: #define kmap_atomic(page, args...) __kmap_atomic(page) to avoid having to touch all kmap_atomic() users in a single patch.

For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as we can access RAM even while in self-refresh mode.

It reads from sequential addresses on the memory bus, and writes repeatedly to the same address on the APB bus. Two transfer modes are supported, oneshot for transferring a known size to or from a peripheral, and continuous for streaming data. In continuous mode, a callback occurs when the buffer is half full to allow the existing data to be handled and a new request queued.x v2 changes: dma API no longer uses PTR_ERR Signed-off-by: Erik Gilling <konkers@android.com> Signed-off-by: Colin Cross <ccross@android.com>
| * | | | [ARM] tegra: Add cpufreq supportColin Cross2010-10-213-0/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement cpufreq support for the Tegra SOC. DVFS is handled by the core virtual cpu clock. The frequencies of the two cores are tied together, the highest frequency requested by either core determines the actual frequency. Signed-off-by: Colin Cross <ccross@android.com>

The lock enable bit is at bit 22 instead of 18 in the MISC register, and the post divider field is a single bit with reversed values from other PLLs. - Simplify recalculating clock rates - Fix UART divider flags - Remove unused clock ops Signed-off-by: Colin Cross <ccross@android.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra SOC contains fuses to identify the CPU type and bin, and a unique id. The CPU info is required to determine the correct voltages for each cpu and core frequency. Signed-off-by: Colin Cross <ccross@android.com>

Setting a pingroup to TEGRA_MUX_SAFE will automatically select a mux setting that is guaranteed not to conflict with any of the hardware blocks. Signed-off-by: Gary King <gking@nvidia.com>
