2011-09-07ARM: davinci: correct MDSTAT_STATE_MASKSergei Shtylyov
MDSTAT.STATE occupies bits 0..5 according to all available documentation, so fix the #define MDSTAT_STATE_MASK at last. Using the wrong value seems to have been harmless though... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
2011-09-07ARM: davinci: da850 EVM: read mac address from SPI flashRajashekhara, Sudhakar
DA850/OMAP-L138 EMAC driver uses random mac address instead of a fixed one because the mac address is not stuffed into EMAC platform data. This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.

2011-08-29ARM: mach-shmobile: Remove 3DG/SGX from sh7372 INTCSMagnus Damm
This patch removes support for the SGX interrupt source in the sh7372 INTCS controller. The SGX hardware block included in sh7372 is already hooked up to the ARM Cortex-A8 core using the INTCA controller, so SGX users are encouraged to make use of that interrupt source instead. Removing support for the SGX interrupt source in INTCS simplifies the sh7372 power management code by allowing us to assume that only INTCA needs to be powered on to operate the SGX hardware. If the INTCS interrupt source would be kept then the kernel would be forced to deal with additional dependencies that does not follow the regular power domain hiearachy. With this patch in place we can safely power down INTCS while the SGX is operating. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2011-08-28ARM: pm: CPU specific code should not overwrite r1 (v:p offset)Russell King
r1 stores the v:p offset from the CPU invariant resume code, and is expected to be preserved by the CPU specific code. Overwriting it is not a good idea. We've managed to get away with it on sa1100 platforms because most happen to have PHYS_OFFSET == PAGE_OFFSET, but that may not be the case depending on kernel configuration. So fix this latent bug. This fixes xsc3 as well which was saving and restoring this register independently. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Fix that by setting only the suspend_noirq and resume_noirq methods with custom versions. Note that all other PM domain methods (including the "normal" suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS, which configures them all to the default subsystem (platform_bus) methods.

2011-08-24ARM: mach-shmobile: sh7372 LCDC1 suspend fixMagnus Damm
Associate the HDMI clock together with LCDC1 on sh7372. Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.

2011-08-15ARM: 7014/1: cache-l2x0: Fix L2 Cache size calculation.Srinivas Kandagatla
This patch fixes L2 Cache size calculations for L2C-210, L2C-310 and PL310, by changing the L2X0_AUX_CTRL_WAY_SIZE_MASK from 2 bits to 3 bits. The Auxiliary Control Register for L2C-210, L2C-310 and PL310 has 3bits [19:17] for Way size, however the existing code only uses 2 bits to get this value. This results in incorrect cachesize calculations. It also results in performing operations on the whole cache when we erroneously decide that the range is big enough (due to l2x0_size being too small) and also prints incorrect cachesize.

2011-08-15ARM: 6967/1: ep93xx: ts72xx: fix board model detectionPetr Štetiar
Fix the obvious error in board detection logic, because according to the TS's manual, the model is stored in the least three significant bits. For example the byte read on my ts-7300 is 0x23 and the detection then fails.
