This adds a driver for the RTC COH 901 331 found in the ST-Ericsson U300 series mobile platforms to the RTC subsystem. It integrates to the ARM kernel support recently added to RMKs ARM tree and will be enabled in the U300 defconfig in due time. Signed-off-by:

This adds a driver for Freescale's MXC internal real time clock modules. The code is taken from Freescale's BSPs, but modified to fit the current kernel coding mechanisms. Also, the PMIC external clock function was removed for now to not add dead bits and keep the code as simple as possible. [akpm@linux-foundation.org: make PIE_BIT_DEF[] static] Signed-off-by:

Support two new half-duplex SPI implementation restrictions, for links that talk to TX-only or RX-only devices. (Existing half-duplex flavors support both transfer directions, just not at the same time.) Move spi_async() into the spi.c core, and stop inlining it. Then make that function perform error checks and reject messages that demand more than the underlying controller can support. Based on a patch from Marek Szyprowski which did this only for the bitbanged GPIO driver. Cc: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by:

Ben Dooks authored
With the update to the spi_bitbang driver, the transfer setup code is being called more often, and thus is often re-doing calculations that have been done before. The SPI layer allows our driver to add its own data to each device so add a result cache to each device. This should also remove the problem where we where directly setting up registers in the setup call which meant we might overwrite the state of an extant transfer., Signed-off-by:

This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it. Signed-off-by:

Anton Vorontsov authored
With this patch spi drivers can use standard spi_driver.id_table and MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like we do with I2C drivers. This is useful when a single driver supports several variants of devices but it is not possible to detect them in run-time (like non-JEDEC chips probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is overkill. This patch also makes life a lot easier on OpenFirmware platforms, since with OF we extensively use proper device IDs in modaliases. Signed-off-by:

After memory hotplug (or other events in future), kcore size can be modified. To update inode->i_size, we have to know inode/dentry but we can't get it from inside /proc directly. But considerinyg memory hotplug, kcore image is updated only when it's opened. Then, updating inode->i_size at open() is enough. Signed-off-by:

Presently the size of /proc/kcore which can be read by 'ls -l' is 0. But it's not the correct value. On x86-64, ls -l shows ... root root 140737486266368 2009-09-17 10:29 /proc/kcore Then, 7FFFFFFE02000. This comes from vmalloc area's size. (*) This shows "core" size, not memory size. This patch shows the size by updating "size" field in struct proc_dir_entry. Later, lookup routine will create inode and fill inode->i_size based on this value. Then, this has a problem. - Once inode is cached, inode->i_size will never be updated. Then, this patch is not memory-hotplug-aware. To update inode->i_size, we have to know dentry or inode. But there is no way to lookup them by inside kernel. Hmmm.... Next patch will try it. Signed-off-by:

Some archs define MODULED_VADDR/MODULES_END which is not in VMALLOC area. This is handled only in x86-64. This patch make it more generic. And we can use vread/vwrite to access the area. Fix it. Signed-off-by:

Benjamin Herrenschmidt <benh@kernel.crashing.org> pointed out that vmemmap range is not included in KCORE_RAM, KCORE_VMALLOC .... This adds KCORE_VMEMMAP if SPARSEMEM_VMEMMAP is used. By this, vmemmap can be readable via /proc/kcore Because it's not vmalloc area, vread/vwrite cannot be used. But the range is static against the memory layout, this patch handles vmemmap area by the same scheme with physical memory. This patch assumes SPARSEMEM_VMEMMAP range is not in VMALLOC range. It's correct now. [akpm@linux-foundation.org: fix typo] Signed-off-by:
