Sometimes, due to high interrupt latency in the continuous mode of DMA transfer, the half buffer complete interrupt is handled after DMA has transferred the full buffer. When this is detected, stop DMA immediately and restart with the next buffer if the next buffer is ready. originally fixed by Victor(Weiguo) Pan <wpan@nvidia.com> In place of using the simple spin_lock()/spi_unlock() in the interrupt thread, using the spin_lock_irqsave() and spin_unlock_irqrestore(). The lock is shared between the normal process context and interrupt context. originally fixed by Laxman Dewangan (ldewangan@nvidia.com) The use of shadow registers caused memory corruption at physical address 0 because the enable bit was not shadowed, and assuming it needed to be set would enable an unconfigured dma block. Most of the register accesses don't need to know the previous state of the registers, and the few places that do need to modify only a few bits in the registers are the same ones that were sometimes incorrectly setting the enable bit. This patch convert tegra_dma_update_hardware to set the entire register, and the other users to read-modify-write, and drops the shadow registers completely. Also fixes missing locking in tegra_dma_allocate_channel Signed-off-by: NColin Cross <ccross@android.com>

On Tegra, calling clk_set_rate on the CPU clock may call into the regulator API. If the regulator driver that controls the CPU voltage rail has been suspended, this can lead to attempted communication with a hardware block that has already been turned off. Adds a SUSPEND_PREPARE notification hook to drop the frequency to the lowest possible during suspend. Also adds 216MHz (off of PLLP) as the lowest CPU frequency, which allows PLLX to be turned off.

This patch fixes bug introduced in revision: f8e9e984 omap1: DMA: move LCD related code from plat-omap to mach-omap1 The code introduced by this patch didn't consider any other CPUs but OMAP1510, which rendered OMAP310 -- which has the same LCD controller -- non-working. Use cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue. Bug found on Palm Zire 71 hardware.

This patch fixes a wrongly used lcd enable pin. The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.

Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs supporting SMP must have the new CPU ID format, so check for this first. Then check for ARM11MPCore, which fails the MPIDR check.

Ensure that the ISA/PCI IO space accessors are properly ordered on ARMv6+ architectures. These should always be ordered with respect to all other accesses.

Disable the initrd if the passed address already overlaps the reserved region. This avoids oopses on Netwinders when NeTTrom tells the kernel that an initrd is located at mem+4MB, but this overlaps the BSS, resulting in the kernels in-use BSS being freed. This should be applied to v2.6.37-stable. Cc: <stable@kernel.org> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
