2010-08-02omap: Devkit8000: Use DIE id to initialize dm9000 MAC addressKan-Ru Chen
The devkit8000 boards often come with empty EEPROM thus without valid ethernet MAC address. The DIE id to MAC formula is copied from u-boot. Signed-off-by: Kan-Ru Chen <kanru@0xlab.org> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-08-02OMAP3: AM3505/3517 do not have IO wakeup capabilitystanley.miao
AM3505/3517 doesn't have IO wakeup capability, so we do not need to set the bit OMAP3430_EN_IO and the bit OMAP3430_EN_IO_CHAIN in the register PM_WKEN_WKUP when the system enters suspend state.

2010-08-02omap2/3/4: serial: errata i202: fix for MDR1 accessDeepak K
Errata i202 (OMAP3430 - 1.12, OMAP3630 - 1.6): UART module MDR1 register access can cause a dummy underrun condition which could result in a freeze in the case of IrDA communication or if used as UART, corrupted data. Workaround is as follows for everytime MDR1 register is changed: * setup all required UART registers * setup MDR1.MODE_SELECT bit field * Wait 5 L4 clk cycles + 5 UART functional clock cycles * Clear the Tx and RX fifo using FCR register Note: The following step is not done as I am assuming it is not needed due to reconfiguration being done and there is no halted operation perse. * Read if required, the RESUME register to resume halted operation Based on an earlier patch at: http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=42d4a342c009bd9727c100abc8a4bc3063c22f0c Signed-off-by: Deepak K <deepak.k@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2010-08-02omap: rx51: Set regulator V28 always onJarkko Nikula
It seems that the battery cover sensor in Nokia N900 is powered from the V28 domain. Now if this regulator is disabled it causes that the gpio 160 reads only zero which effectively causes uSD removal detection. Currently the bootloader enabled V28 is kept on but this may change in the future according to comment in drivers/regulator/core.c: regulator_has_full_constraints. Also if there are any consumers on the V28 domain doing regulator_enable regulator_disable cycle the V28 will be disabled after that. Prepare for these by defining the V28 as always_on regulator.
