| * microblaze: Fix build with make 3.82Thomas Backlund2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | When running make headers_install_all on x86_64 and make 3.82 I hit this: arch/microblaze/Makefile:80: *** mixed implicit and normal rules. Stop. make: *** [headers_install_all] Error 2 So split the rules to satisfy make 3.82.

| | | | | | | | | | | | | | | | | | | | | | | | DCR bus is natively used for PowerPC. Microblaze has no infrastructure for compile DCR that's why is necessary to exclude it.

| * microblaze: Support C optimized lib functions for little-endianMichal Simek2010-10-21
| | | | | | | | | | | | | | | | Optimized C library functions can rapidly speedup the kernel. memset doesn't need to be optimized because there is no difference in behavior on little/big endian cpu. Signed-off-by: Michal Simek <monstr@monstr.eu>

| * microblaze: Support timer on AXI liteMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | | | | | New microblaze systems uses two buses. One for memories and flashes and the second for low-speed peripherals which can run on different CLK. This is the reason why the kernel is trying to read clock-frequency directly from node. If there is then the kernel will work with it. If not then cpu CLK is used.

| * microblaze: Add support for little-endian MicroblazeMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.

| * microblaze: Do not compile early console support for uartlite if is disabledMichal Simek2010-10-21

| * microblaze: Report if only one timer is usedMichal Simek2010-10-21
| | | | | | | | | | | | | | | | | | Kernel needs two timers because of clocksource and clockevent. It is better to show warning message directly on early console if available. If it isn't available kernel log buffer contains it. Signed-off-by: Michal Simek <monstr@monstr.eu>

| * | hwmon: lis3: use block read to access data registersSamu Onkalo2010-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add optional blockread function to interface driver. If available the chip driver uses it for data register access. For 12 bit device it reads 6 bytes to get 3*16bit data. For 8 bit device it reads out 5 bytes since every second byte is dummy. This optimizes bus usage and reduces number of operations and interrupts needed for one data update.

If default rate is 0, reset default value is used. Added control for duration via platform data. Added possibility to configure interrupts to trig on both rising and falling edge. The lis3 WU unit can be configured quite many ways and with some configurations it is quite handy to get coordinate refresh when some event trigs and when it reason goes away.
